Trigger Api Again After Few Javascript
JavaScript
Bring Bootstrap's components to life with over a dozen custom jQuery plugins. Hands include them all, or one by one.
Individual or compiled
Plugins can be included individually (using Bootstrap'south private *.js files), or all at once (using bootstrap.js or the minified bootstrap.min.js).
Using the compiled JavaScript
Both bootstrap.js and bootstrap.min.js contain all plugins in a single file. Include only ane.
Plugin dependencies
Some plugins and CSS components depend on other plugins. If yous include plugins individually, brand certain to check for these dependencies in the docs. Also note that all plugins depend on jQuery (this means jQuery must be included before the plugin files). Consult our bower.json to see which versions of jQuery are supported.
Data attributes
You can use all Bootstrap plugins purely through the markup API without writing a single line of JavaScript. This is Bootstrap's first-form API and should be your first consideration when using a plugin.
That said, in some situations it may be desirable to turn this functionality off. Therefore, we as well provide the power to disable the data attribute API by unbinding all events on the document namespaced with data-api. This looks like this:
$ ( document ). off ( '.data-api' ) Alternatively, to target a specific plugin, simply include the plugin'southward name as a namespace along with the information-api namespace like this:
$ ( certificate ). off ( '.alert.data-api' ) Only i plugin per element via information attributes
Don't apply information attributes from multiple plugins on the same element. For example, a button cannot both have a tooltip and toggle a modal. To attain this, use a wrapping element.
Programmatic API
We as well believe y'all should be able to use all Bootstrap plugins purely through the JavaScript API. All public APIs are single, chainable methods, and return the drove acted upon.
$ ( '.btn.danger' ). push ( 'toggle' ). addClass ( 'fat' ) All methods should accept an optional options object, a cord which targets a detail method, or nothing (which initiates a plugin with default behavior):
$ ( '#myModal' ). modal () // initialized with defaults $ ( '#myModal' ). modal ({ keyboard : imitation }) // initialized with no keyboard $ ( '#myModal' ). modal ( 'show' ) // initializes and invokes show immediately Each plugin besides exposes its raw constructor on a Constructor belongings: $.fn.popover.Constructor. If you'd similar to get a particular plugin instance, retrieve it direct from an chemical element: $('[rel="popover"]').data('popover').
Default settings
You can modify the default settings for a plugin by modifying the plugin's Constructor.DEFAULTS object:
$ . fn . modal . Constructor . DEFAULTS . keyboard = false // changes default for the modal plugin's `keyboard` selection to imitation No conflict
Sometimes it is necessary to apply Bootstrap plugins with other UI frameworks. In these circumstances, namespace collisions tin can occasionally occur. If this happens, you may phone call .noConflict on the plugin yous wish to revert the value of.
var bootstrapButton = $ . fn . push . noConflict () // return $.fn.button to previously assigned value $ . fn . bootstrapBtn = bootstrapButton // requite $().bootstrapBtn the Bootstrap functionality Events
Bootstrap provides custom events for most plugins' unique actions. More often than not, these come up in an infinitive and past participle course - where the infinitive (ex. testify) is triggered at the offset of an consequence, and its by participle form (ex. shown) is triggered on the completion of an action.
As of iii.0.0, all Bootstrap events are namespaced.
All infinitive events provide preventDefault functionality. This provides the ability to stop the execution of an action earlier it starts.
$ ( '#myModal' ). on ( 'show.bs.modal' , office ( due east ) { if ( ! data ) return e . preventDefault () // stops modal from being shown }) Version numbers
The version of each of Bootstrap'southward jQuery plugins can be accessed via the VERSION property of the plugin's constructor. For example, for the tooltip plugin:
$ . fn . tooltip . Constructor . VERSION // => "3.three.7" No special fallbacks when JavaScript is disabled
Bootstrap's plugins don't fall back particularly gracefully when JavaScript is disabled. If you care about the user feel in this case, utilise <noscript> to explain the situation (and how to re-enable JavaScript) to your users, and/or add your ain custom fallbacks.
Third-party libraries
Bootstrap does non officially support third-party JavaScript libraries similar Image or jQuery UI. Despite .noConflict and namespaced events, there may be compatibility problems that yous need to gear up on your ain.
About transitions
For simple transition furnishings, include transition.js once alongside the other JS files. If you're using the compiled (or minified) bootstrap.js, in that location is no need to include this—information technology's already there.
What's inside
Transition.js is a bones helper for transitionEnd events too as a CSS transition emulator. It'south used past the other plugins to check for CSS transition support and to grab hanging transitions.
Disabling transitions
Transitions tin be globally disabled using the following JavaScript snippet, which must come after transition.js (or bootstrap.js or bootstrap.min.js, as the case may be) has loaded:
$ . support . transition = false Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.
Multiple open modals non supported
Be sure non to open a modal while some other is still visible. Showing more than one modal at a fourth dimension requires custom code.
Modal markup placement
E'er endeavour to place a modal's HTML code in a superlative-level position in your document to avert other components affecting the modal'due south appearance and/or functionality.
Due to how HTML5 defines its semantics, the autofocus HTML aspect has no issue in Bootstrap modals. To accomplish the same effect, use some custom JavaScript:
$ ( '#myModal' ). on ( 'shown.bs.modal' , function () { $ ( '#myInput' ). focus () }) Examples
Static case
A rendered modal with header, trunk, and set up of actions in the footer.
<div class= "modal fade" tabindex= "-i" role= "dialog" > <div class= "modal-dialog" role= "document" > <div class= "modal-content" > <div class= "modal-header" > <button type= "button" class= "shut" data-dismiss= "modal" aria-characterization= "Close" ><span aria-hidden= "true" > × </span></button> <h4 class= "modal-championship" >Modal title</h4> </div> <div form= "modal-trunk" > <p>Ane fine body… </p> </div> <div class= "modal-footer" > <button type= "button" grade= "btn btn-default" information-dismiss= "modal" >Close</button> <push type= "button" class= "btn btn-primary" >Save changes</button> </div> </div> <!-- /.modal-content --> </div> <!-- /.modal-dialog --> </div> <!-- /.modal --> Alive demo
Toggle a modal via JavaScript by clicking the button beneath. Information technology volition slide downwards and fade in from the top of the page.
<!-- Push button trigger modal --> <push type= "button" class= "btn btn-primary btn-lg" information-toggle= "modal" information-target= "#myModal" > Launch demo modal </button> <!-- Modal --> <div grade= "modal fade" id= "myModal" tabindex= "-1" function= "dialog" aria-labelledby= "myModalLabel" > <div grade= "modal-dialog" role= "document" > <div class= "modal-content" > <div class= "modal-header" > <button type= "button" course= "shut" information-dismiss= "modal" aria-label= "Close" ><span aria-hidden= "true" > × </bridge></push> <h4 class= "modal-title" id= "myModalLabel" >Modal championship</h4> </div> <div course= "modal-body" > ... </div> <div class= "modal-footer" > <button type= "button" class= "btn btn-default" data-dismiss= "modal" >Close</push button> <button type= "button" course= "btn btn-chief" >Save changes</button> </div> </div> </div> </div> Make modals accessible
Exist sure to add role="dialog" and aria-labelledby="...", referencing the modal championship, to .modal, and role="document" to the .modal-dialog itself.
Additionally, yous may give a clarification of your modal dialog with aria-describedby on .modal.
Embedding YouTube videos
Embedding YouTube videos in modals requires additional JavaScript not in Bootstrap to automatically stop playback and more. See this helpful Stack Overflow post for more than information.
Optional sizes
Modals have 2 optional sizes, available via modifier classes to be placed on a .modal-dialog.
<!-- Big modal --> <button blazon= "push" class= "btn btn-chief" information-toggle= "modal" data-target= ".bs-example-modal-lg" >Large modal</button> <div class= "modal fade bs-instance-modal-lg" tabindex= "-1" role= "dialog" aria-labelledby= "myLargeModalLabel" > <div class= "modal-dialog modal-lg" role= "certificate" > <div class= "modal-content" > ... </div> </div> </div> <!-- Pocket-size modal --> <button type= "button" grade= "btn btn-primary" data-toggle= "modal" data-target= ".bs-case-modal-sm" >Small modal</button> <div class= "modal fade bs-example-modal-sm" tabindex= "-ane" role= "dialog" aria-labelledby= "mySmallModalLabel" > <div form= "modal-dialog modal-sm" function= "certificate" > <div class= "modal-content" > ... </div> </div> </div> Remove animation
For modals that only announced rather than fade in to view, remove the .fade class from your modal markup.
<div class= "modal" tabindex= "-1" role= "dialog" aria-labelledby= "..." > ... </div> Using the filigree system
To take reward of the Bootstrap grid system inside a modal, just nest .rowsouth within the .modal-body and so utilize the normal grid system classes.
<div grade= "modal fade" tabindex= "-1" part= "dialog" aria-labelledby= "gridSystemModalLabel" > <div grade= "modal-dialog" role= "certificate" > <div class= "modal-content" > <div course= "modal-header" > <button type= "button" class= "shut" data-dismiss= "modal" aria-label= "Close" ><span aria-subconscious= "true" > × </span></button> <h4 class= "modal-championship" id= "gridSystemModalLabel" >Modal title</h4> </div> <div grade= "modal-torso" > <div course= "row" > <div class= "col-md-iv" >.col-md-4</div> <div course= "col-md-4 col-medico-get-go-4" >.col-md-4 .col-physician-start-4</div> </div> <div grade= "row" > <div course= "col-dr.-3 col-physician-offset-3" >.col-dr.-3 .col-physician-kickoff-3</div> <div class= "col-doc-2 col-md-offset-4" >.col-dr.-2 .col-doctor-starting time-4</div> </div> <div class= "row" > <div class= "col-md-six col-doctor-offset-3" >.col-md-6 .col-physician-offset-3</div> </div> <div class= "row" > <div form= "col-sm-9" > Level one: .col-sm-9 <div class= "row" > <div class= "col-xs-8 col-sm-6" > Level 2: .col-xs-8 .col-sm-6 </div> <div grade= "col-xs-four col-sm-6" > Level 2: .col-xs-4 .col-sm-6 </div> </div> </div> </div> </div> <div form= "modal-footer" > <push type= "button" class= "btn btn-default" information-dismiss= "modal" >Shut</button> <button type= "button" class= "btn btn-primary" >Save changes</button> </div> </div> <!-- /.modal-content --> </div> <!-- /.modal-dialog --> </div> <!-- /.modal --> Have a bunch of buttons that all trigger the same modal, just with slightly different contents? Use upshot.relatedTarget and HTML data-* attributes (mayhap via jQuery) to vary the contents of the modal depending on which push was clicked. Encounter the Modal Events docs for details on relatedTarget,
<button type= "button" class= "btn btn-primary" data-toggle= "modal" data-target= "#exampleModal" data-whatsoever= "@mdo" >Open modal for @mdo</push button> <button blazon= "button" class= "btn btn-master" data-toggle= "modal" data-target= "#exampleModal" information-any= "@fat" >Open up modal for @fat</push button> <push type= "button" form= "btn btn-primary" data-toggle= "modal" information-target= "#exampleModal" data-whatever= "@getbootstrap" >Open modal for @getbootstrap</button> ...more buttons... <div class= "modal fade" id= "exampleModal" tabindex= "-i" role= "dialog" aria-labelledby= "exampleModalLabel" > <div class= "modal-dialog" role= "document" > <div class= "modal-content" > <div class= "modal-header" > <button type= "button" course= "shut" data-dismiss= "modal" aria-characterization= "Close" ><span aria-hidden= "true" > × </bridge></push button> <h4 course= "modal-title" id= "exampleModalLabel" >New bulletin</h4> </div> <div form= "modal-body" > <form> <div class= "course-group" > <label for= "recipient-name" class= "control-label" >Recipient:</label> <input blazon= "text" class= "grade-command" id= "recipient-name" > </div> <div class= "form-group" > <label for= "message-text" class= "control-label" >Bulletin:</characterization> <textarea class= "grade-control" id= "message-text" ></textarea> </div> </form> </div> <div class= "modal-footer" > <push button blazon= "push" class= "btn btn-default" data-dismiss= "modal" >Close</button> <push type= "button" class= "btn btn-principal" >Send message</button> </div> </div> </div> </div> $ ( '#exampleModal' ). on ( 'evidence.bs.modal' , office ( issue ) { var button = $ ( event . relatedTarget ) // Push button that triggered the modal var recipient = push button . data ( 'whatever' ) // Excerpt info from data-* attributes // If necessary, you could initiate an AJAX asking here (and then do the updating in a callback). // Update the modal'south content. Nosotros'll utilize jQuery here, but you could use a information bounden library or other methods instead. var modal = $ ( this ) modal . find ( '.modal-title' ). text ( 'New message to ' + recipient ) modal . discover ( '.modal-torso input' ). val ( recipient ) }) Usage
The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. Information technology besides adds .modal-open to the <body> to override default scrolling beliefs and generates a .modal-backdrop to provide a click area for dismissing shown modals when clicking outside the modal.
Via information attributes
Activate a modal without writing JavaScript. Set data-toggle="modal" on a controller element, like a button, along with a data-target="#foo" or href="#foo" to target a specific modal to toggle.
<button type= "button" data-toggle= "modal" data-target= "#myModal" >Launch modal</button> Via JavaScript
Telephone call a modal with id myModal with a single line of JavaScript:
$ ( '#myModal' ). modal ( options ) Options
Options can exist passed via information attributes or JavaScript. For data attributes, append the option name to data-, equally in data-backdrop="".
| Name | blazon | default | description |
|---|---|---|---|
| backdrop | boolean or the string 'static' | truthful | Includes a modal-backdrop element. Alternatively, specify static for a backdrop which doesn't close the modal on click. |
| keyboard | boolean | true | Closes the modal when escape cardinal is pressed |
| evidence | boolean | true | Shows the modal when initialized. |
| remote | path | false | This choice is deprecated since v3.3.0 and has been removed in v4. We recommend instead using client-side templating or a data binding framework, or calling jQuery.load yourself. If a remote URL is provided, content will be loaded one fourth dimension via jQuery'due south |
Methods
.modal(options)
Activates your content as a modal. Accepts an optional options object.
$ ( '#myModal' ). modal ({ keyboard : false }) .modal('toggle')
Manually toggles a modal. Returns to the caller before the modal has really been shown or hidden (i.e. before the shown.bs.modal or subconscious.bs.modal event occurs).
$ ( '#myModal' ). modal ( 'toggle' ) .modal('show')
Manually opens a modal. Returns to the caller before the modal has actually been shown (i.e. before the shown.bs.modal event occurs).
$ ( '#myModal' ). modal ( 'evidence' ) .modal('hide')
Manually hides a modal. Returns to the caller before the modal has actually been hidden (i.due east. earlier the hidden.bs.modal event occurs).
$ ( '#myModal' ). modal ( 'hide' ) .modal('handleUpdate')
Readjusts the modal's positioning to counter a scrollbar in case ane should appear, which would brand the modal jump to the left.
But needed when the superlative of the modal changes while it is open.
$ ( '#myModal' ). modal ( 'handleUpdate' ) Events
Bootstrap's modal class exposes a few events for hooking into modal functionality.
All modal events are fired at the modal itself (i.due east. at the <div class="modal">).
| Event Type | Description |
|---|---|
| show.bs.modal | This event fires immediately when the show instance method is called. If caused by a click, the clicked element is available as the relatedTarget holding of the event. |
| shown.bs.modal | This upshot is fired when the modal has been made visible to the user (will expect for CSS transitions to complete). If acquired past a click, the clicked element is available as the relatedTarget holding of the event. |
| hide.bs.modal | This event is fired immediately when the hide instance method has been called. |
| hidden.bs.modal | This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete). |
| loaded.bs.modal | This event is fired when the modal has loaded content using the remote option. |
$ ( '#myModal' ). on ( 'hidden.bs.modal' , function ( e ) { // do something... }) Examples
Add together dropdown menus to most annihilation with this uncomplicated plugin, including the navbar, tabs, and pills.
Within a navbar
Within pills
Usage
Via data attributes or JavaScript, the dropdown plugin toggles subconscious content (dropdown menus) by toggling the .open class on the parent list item.
On mobile devices, opening a dropdown adds a .dropdown-backdrop equally a tap area for closing dropdown menus when tapping outside the carte du jour, a requirement for proper iOS support. This ways that switching from an open up dropdown card to a different dropdown carte du jour requires an extra tap on mobile.
Note: The data-toggle="dropdown" attribute is relied on for closing dropdown menus at an application level, then it'southward a good idea to ever use information technology.
Via data attributes
Add information-toggle="dropdown" to a link or push to toggle a dropdown.
<div class= "dropdown" > <push id= "dLabel" type= "button" information-toggle= "dropdown" aria-haspopup= "truthful" aria-expanded= "faux" > Dropdown trigger <span class= "caret" ></span> </push> <ul class= "dropdown-bill of fare" aria-labelledby= "dLabel" > ... </ul> </div> To go on URLs intact with link buttons, utilise the data-target attribute instead of href="#".
<div class= "dropdown" > <a id= "dLabel" data-target= "#" href= "http://example.com/" data-toggle= "dropdown" role= "button" aria-haspopup= "true" aria-expanded= "false" > Dropdown trigger <span class= "caret" ></span> </a> <ul class= "dropdown-menu" aria-labelledby= "dLabel" > ... </ul> </div> Via JavaScript
Call the dropdowns via JavaScript:
$ ( '.dropdown-toggle' ). dropdown () information-toggle="dropdown" still required
Regardless of whether you call your dropdown via JavaScript or instead use the data-api, data-toggle="dropdown" is always required to be nowadays on the dropdown's trigger chemical element.
Options
None
Methods
$().dropdown('toggle')
Toggles the dropdown carte of a given navbar or tabbed navigation.
Events
All dropdown events are fired at the .dropdown-menu'southward parent chemical element.
All dropdown events have a relatedTarget property, whose value is the toggling anchor element.
| Event Type | Description |
|---|---|
| prove.bs.dropdown | This effect fires immediately when the show instance method is called. |
| shown.bs.dropdown | This issue is fired when the dropdown has been made visible to the user (will await for CSS transitions, to complete). |
| hide.bs.dropdown | This event is fired immediately when the hide example method has been chosen. |
| hidden.bs.dropdown | This event is fired when the dropdown has finished existence hidden from the user (will wait for CSS transitions, to complete). |
$ ( '#myDropdown' ). on ( 'show.bs.dropdown' , function () { // exercise something… }) The ScrollSpy plugin is for automatically updating nav targets based on scroll position. Scroll the expanse below the navbar and sentry the active grade modify. The dropdown sub items will be highlighted too.
Requires relative positioning
No matter the implementation method, scrollspy requires the use of position: relative; on the element you're spying on. In nearly cases this is the <body>. When scrollspying on elements other than the <body>, be sure to take a meridian set and overflow-y: scroll; practical.
Via data attributes
To easily add together scrollspy beliefs to your topbar navigation, add data-spy="scroll" to the chemical element you want to spy on (about typically this would be the <body>). Then add the data-target aspect with the ID or class of the parent element of any Bootstrap .nav component.
body { position : relative ; } <body data-spy= "scroll" data-target= "#navbar-example" > ... <div id= "navbar-instance" > <ul class= "nav nav-tabs" role= "tablist" > ... </ul> </div> ... </body> Via JavaScript
Subsequently adding position: relative; in your CSS, call the scrollspy via JavaScript:
$ ( 'body' ). scrollspy ({ target : '#navbar-example' }) Methods
.scrollspy('refresh')
When using scrollspy in conjunction with adding or removing of elements from the DOM, y'all'll demand to telephone call the refresh method like so:
$ ( '[data-spy="curl"]' ). each ( role () { var $spy = $ ( this ). scrollspy ( 'refresh' ) }) Options
Options tin can exist passed via data attributes or JavaScript. For data attributes, append the pick proper noun to data-, as in data-commencement="".
| Name | type | default | description |
|---|---|---|---|
| beginning | number | x | Pixels to beginning from tiptop when computing position of roll. |
Events
| Event Type | Description |
|---|---|
| activate.bs.scrollspy | This event fires whenever a new particular becomes activated by the scrollspy. |
$ ( '#myScrollspy' ). on ( 'actuate.bs.scrollspy' , function () { // do something… }) Case tabs
Add quick, dynamic tab functionality to transition through panes of local content, even via dropdown menus. Nested tabs are not supported.

Usage
Enable tabbable tabs via JavaScript (each tab needs to exist activated individually):
$ ( '#myTabs a' ). click ( function ( e ) { e . preventDefault () $ ( this ). tab ( 'show' ) }) You lot can activate private tabs in several ways:
$ ( '#myTabs a[href="#profile"]' ). tab ( 'show' ) // Select tab by name $ ( '#myTabs a:commencement' ). tab ( 'show' ) // Select first tab $ ( '#myTabs a:last' ). tab ( 'show' ) // Select last tab $ ( '#myTabs li:eq(2) a' ). tab ( 'show' ) // Select third tab (0-indexed) Markup
You tin can activate a tab or pill navigation without writing any JavaScript by only specifying data-toggle="tab" or data-toggle="pill" on an element. Adding the nav and nav-tabs classes to the tab ul will apply the Bootstrap tab styling, while adding the nav and nav-pills classes volition apply pill styling.
<div> <!-- Nav tabs --> <ul class= "nav nav-tabs" role= "tablist" > <li role= "presentation" class= "active" ><a href= "#dwelling" aria-controls= "abode" part= "tab" data-toggle= "tab" >Home</a></li> <li role= "presentation" ><a href= "#profile" aria-controls= "profile" part= "tab" data-toggle= "tab" >Contour</a></li> <li part= "presentation" ><a href= "#messages" aria-controls= "messages" role= "tab" data-toggle= "tab" >Messages</a></li> <li part= "presentation" ><a href= "#settings" aria-controls= "settings" role= "tab" data-toggle= "tab" >Settings</a></li> </ul> <!-- Tab panes --> <div form= "tab-content" > <div role= "tabpanel" course= "tab-pane active" id= "domicile" >...</div> <div role= "tabpanel" class= "tab-pane" id= "profile" >...</div> <div part= "tabpanel" class= "tab-pane" id= "messages" >...</div> <div role= "tabpanel" class= "tab-pane" id= "settings" >...</div> </div> </div> Fade effect
To make tabs fade in, add .fade to each .tab-pane. The get-go tab pane must too have .in to brand the initial content visible.
<div class= "tab-content" > <div role= "tabpanel" class= "tab-pane fade in active" id= "home" >...</div> <div part= "tabpanel" class= "tab-pane fade" id= "profile" >...</div> <div function= "tabpanel" class= "tab-pane fade" id= "letters" >...</div> <div role= "tabpanel" class= "tab-pane fade" id= "settings" >...</div> </div> Methods
$().tab
Activates a tab element and content container. Tab should have either a data-target or an href targeting a container node in the DOM. In the to a higher place examples, the tabs are the <a>s with information-toggle="tab" attributes.
.tab('show')
Selects the given tab and shows its associated content. Any other tab that was previously selected becomes unselected and its associated content is hidden. Returns to the caller before the tab pane has really been shown (i.due east. before the shown.bs.tab event occurs).
$ ( '#someTab' ). tab ( 'prove' ) Events
When showing a new tab, the events fire in the post-obit order:
-
hide.bs.tab(on the current active tab) -
show.bs.tab(on the to-exist-shown tab) -
hidden.bs.tab(on the previous agile tab, the same one as for thehide.bs.taboutcome) -
shown.bs.tab(on the newly-active just-shown tab, the same one as for theshow.bs.tabconsequence)
If no tab was already agile, then the hibernate.bs.tab and hidden.bs.tab events will not be fired.
| Consequence Type | Description |
|---|---|
| testify.bs.tab | This event fires on tab show, but earlier the new tab has been shown. Employ consequence.target and event.relatedTarget to target the active tab and the previous agile tab (if bachelor) respectively. |
| shown.bs.tab | This event fires on tab prove subsequently a tab has been shown. Use event.target and result.relatedTarget to target the agile tab and the previous active tab (if bachelor) respectively. |
| hide.bs.tab | This event fires when a new tab is to be shown (and thus the previous agile tab is to be hidden). Employ outcome.target and event.relatedTarget to target the current active tab and the new before longhoped-for-active tab, respectively. |
| subconscious.bs.tab | This event fires afterward a new tab is shown (and thus the previous active tab is subconscious). Use event.target and event.relatedTarget to target the previous active tab and the new active tab, respectively. |
$ ( 'a[data-toggle="tab"]' ). on ( 'shown.bs.tab' , part ( e ) { e . target // newly activated tab e . relatedTarget // previous active tab }) Inspired by the excellent jQuery.tipsy plugin written by Jason Frame; Tooltips are an updated version, which don't rely on images, use CSS3 for animations, and information-attributes for local title storage.
Tooltips with zero-length titles are never displayed.

Static tooltip
Four options are available: top, right, bottom, and left aligned.
Four directions
<push button type= "button" course= "btn btn-default" information-toggle= "tooltip" data-placement= "left" title= "Tooltip on left" >Tooltip on left</push button> <button blazon= "button" class= "btn btn-default" data-toggle= "tooltip" information-placement= "top" title= "Tooltip on tiptop" >Tooltip on top</push> <push button type= "button" class= "btn btn-default" data-toggle= "tooltip" data-placement= "bottom" title= "Tooltip on bottom" >Tooltip on bottom</button> <push type= "push" class= "btn btn-default" data-toggle= "tooltip" data-placement= "right" title= "Tooltip on right" >Tooltip on right</push> The tooltip plugin generates content and markup on demand, and past default places tooltips after their trigger element.
Trigger the tooltip via JavaScript:
$ ( '#example' ). tooltip ( options ) Markup
The required markup for a tooltip is only a data attribute and championship on the HTML element you wish to take a tooltip. The generated markup of a tooltip is rather simple, though information technology does require a position (past default, set to height by the plugin).
<!-- HTML to write --> <a href= "#" data-toggle= "tooltip" title= "Some tooltip text!" >Hover over me</a> <!-- Generated markup past the plugin --> <div course= "tooltip superlative" function= "tooltip" > <div grade= "tooltip-arrow" ></div> <div grade= "tooltip-inner" > Some tooltip text! </div> </div> Options

Methods
$().tooltip(options)
Attaches a tooltip handler to an chemical element collection.
.tooltip('show')
Reveals an element's tooltip. Returns to the caller before the tooltip has actually been shown (i.e. before the shown.bs.tooltip event occurs). This is considered a "manual" triggering of the tooltip. Tooltips with cypher-length titles are never displayed.
$ ( '#chemical element' ). tooltip ( 'show' ) .tooltip('hide')
Hides an element'due south tooltip. Returns to the caller before the tooltip has actually been hidden (i.due east. before the hidden.bs.tooltip event occurs). This is considered a "manual" triggering of the tooltip.
$ ( '#element' ). tooltip ( 'hide' ) .tooltip('toggle')
Toggles an element's tooltip. Returns to the caller earlier the tooltip has actually been shown or hidden (i.east. before the shown.bs.tooltip or hidden.bs.tooltip event occurs). This is considered a "transmission" triggering of the tooltip.
$ ( '#chemical element' ). tooltip ( 'toggle' ) .tooltip('destroy')
Hides and destroys an element's tooltip. Tooltips that use delegation (which are created using the selector option) cannot be individually destroyed on descendant trigger elements.
$ ( '#element' ). tooltip ( 'destroy' ) Events
| Result Type | Description |
|---|---|
| show.bs.tooltip | This upshot fires immediately when the show example method is chosen. |
| shown.bs.tooltip | This event is fired when the tooltip has been made visible to the user (will await for CSS transitions to complete). |
| hide.bs.tooltip | This consequence is fired immediately when the hide instance method has been called. |
| hidden.bs.tooltip | This event is fired when the tooltip has finished existence subconscious from the user (will wait for CSS transitions to complete). |

$ ( '#myTooltip' ). on ( 'hidden.bs.tooltip' , part () { // do something… }) Add pocket-sized overlays of content, like those on the iPad, to whatsoever element for housing secondary data.
Popovers whose both title and content are naught-length are never displayed.
Opt-in functionality
For operation reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.
One way to initialize all popovers on a folio would exist to select them by their data-toggle attribute:
$ ( function () { $ ( '[information-toggle="popover"]' ). popover () }) Popovers in button groups, input groups, and tables require special setting
When using popovers on elements inside a .btn-group or an .input-group, or on tabular array-related elements (<td>, <thursday>, <tr>, <thead>, <tbody>, <tfoot>), you'll have to specify the option container: 'body' (documented beneath) to avoid unwanted side effects (such as the chemical element growing wider and/or losing its rounded corners when the popover is triggered).
Popovers on disabled elements require wrapper elements
To add a popover to a disabled or .disabled element, put the chemical element within of a <div> and utilise the popover to that <div> instead.
Multiple-line links
Sometimes you want to add a popover to a hyperlink that wraps multiple lines. The default behavior of the popover plugin is to eye it horizontally and vertically. Add white-space: nowrap; to your anchors to avoid this.
Examples
Static popover
Four options are available: top, right, bottom, and left aligned.
Popover peak
Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.
Popover right
Sed posuere consectetur est at lobortis. Aenean european union leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.
Popover bottom
Sed posuere consectetur est at lobortis. Aenean european union leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.
Popover left
Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

Options for individual popovers can alternatively exist specified through the utilize of data attributes, as explained to a higher place.
Methods
$().popover(options)
Initializes popovers for an chemical element collection.
.popover('bear witness')
Reveals an element'due south popover. Returns to the caller before the popover has really been shown (i.due east. before the shown.bs.popover event occurs). This is considered a "transmission" triggering of the popover. Popovers whose both title and content are zero-length are never displayed.

$ ( '#myPopover' ). on ( 'subconscious.bs.popover' , office () { // do something… }) Example alerts
Add dismiss functionality to all alert messages with this plugin.
When using a .close button, it must exist the get-go child of the .warning-dismissible and no text content may come before it in the markup.
Usage
But add data-dismiss="alarm" to your shut button to automatically give an alert shut functionality. Closing an warning removes it from the DOM.
<push type= "push" grade= "shut" data-dismiss= "alarm" aria-characterization= "Shut" > <span aria-subconscious= "true" > × </span> </push> To have your alerts use blitheness when closing, make sure they have the .fade and .in classes already applied to them.
Methods
$().alert()
Makes an alert listen for click events on descendant elements which have the data-dismiss="alert" aspect. (Non necessary when using the data-api's motorcar-initialization.)
$().alert('shut')
Closes an alert past removing it from the DOM. If the .fade and .in classes are present on the element, the alarm volition fade out before it is removed.
Events
Bootstrap's alert plugin exposes a few events for hooking into alert functionality.
| Event Blazon | Description |
|---|---|
| close.bs.alert | This event fires immediately when the close instance method is called. |
| airtight.bs.warning | This event is fired when the alert has been closed (volition wait for CSS transitions to consummate). |
$ ( '#myAlert' ). on ( 'closed.bs.alert' , function () { // exercise something… }) Do more with buttons. Command push states or create groups of buttons for more components like toolbars.
Stateful
Add data-loading-text="Loading..." to utilise a loading state on a push button.
This feature is deprecated since v3.three.5 and has been removed in v4.
Apply whichever state y'all like!
For the sake of this demonstration, nosotros are using data-loading-text and $().button('loading'), but that's non the only state you can apply. Meet more on this beneath in the $().push(cord) documentation.
<push button type= "button" id= "myButton" data-loading-text= "Loading..." class= "btn btn-primary" autocomplete= "off" > Loading state </button> <script> $ ( '#myButton' ). on ( 'click' , function () { var $btn = $ ( this ). button ( 'loading' ) // business logic... $btn . button ( 'reset' ) }) </script> Single toggle
Add data-toggle="button" to activate toggling on a single button.
Pre-toggled buttons demand .active and aria-pressed="true"
For pre-toggled buttons, y'all must add together the .active class and the aria-pressed="true" attribute to the button yourself.
<button type= "button" class= "btn btn-primary" information-toggle= "button" aria-pressed= "false" autocomplete= "off" > Unmarried toggle </push button> Checkbox / Radio
Add data-toggle="buttons" to a .btn-grouping containing checkbox or radio inputs to enable toggling in their respective styles.
Preselected options need .agile
For preselected options, you must add the .active grade to the input's characterization yourself.
Visual checked country merely updated on click
If the checked state of a checkbox button is updated without firing a click event on the button (e.k. via <input type="reset"> or via setting the checked belongings of the input), you will need to toggle the .active class on the input's label yourself.
<div grade= "btn-group" data-toggle= "buttons" > <label class= "btn btn-primary agile" > <input type= "checkbox" autocomplete= "off" checked > Checkbox 1 (pre-checked) </label> <label class= "btn btn-chief" > <input blazon= "checkbox" autocomplete= "off" > Checkbox 2 </label> <characterization course= "btn btn-primary" > <input blazon= "checkbox" autocomplete= "off" > Checkbox three </label> </div>
<div class= "btn-group" data-toggle= "buttons" > <characterization class= "btn btn-primary agile" > <input type= "radio" proper name= "options" id= "option1" autocomplete= "off" checked > Radio one (preselected) </label> <label class= "btn btn-master" > <input blazon= "radio" name= "options" id= "option2" autocomplete= "off" > Radio 2 </label> <label class= "btn btn-principal" > <input type= "radio" name= "options" id= "option3" autocomplete= "off" > Radio 3 </label> </div> Methods
$().button('toggle')
Toggles push state. Gives the button the advent that it has been activated.
$().push('reset')
Resets push land - swaps text to original text. This method is asynchronous and returns before the resetting has really completed.
$().button(string)
Swaps text to any data divers text state.
<button blazon= "button" id= "myStateButton" information-consummate-text= "finished!" class= "btn btn-principal" autocomplete= "off" > ... </push button> <script> $ ( '#myStateButton' ). on ( 'click' , part () { $ ( this ). button ( 'complete' ) // push text will exist "finished!" }) </script> Flexible plugin that utilizes a handful of classes for easy toggle beliefs.
Plugin dependency
Collapse requires the transitions plugin to exist included in your version of Bootstrap.
Example
Click the buttons below to show and hibernate another chemical element via class changes:
-
.collapsehides content -
.collapsingis practical during transitions -
.collapse.inshows content
You can utilise a link with the href attribute, or a push with the information-target attribute. In both cases, the information-toggle="plummet" is required.

Make expand/collapse controls attainable
Exist sure to add aria-expanded to the control element. This aspect explicitly defines the current state of the collapsible element to screen readers and similar assistive technologies. If the collapsible element is closed by default, it should accept a value of aria-expanded="false". If you've set the collapsible element to exist open by default using the in form, prepare aria-expanded="true" on the control instead. The plugin will automatically toggle this attribute based on whether or non the collapsible chemical element has been opened or closed.
Additionally, if your control element is targeting a single collapsible chemical element – i.eastward. the data-target attribute is pointing to an id selector – yous may add an additional aria-controls aspect to the control chemical element, containing the id of the collapsible chemical element. Modern screen readers and similar assistive technologies brand employ of this attribute to provide users with additional shortcuts to navigate directly to the collapsible element itself.
Usage
The collapse plugin utilizes a few classes to handle the heavy lifting:
-
.collapsehides the content -
.plummet.inshows the content -
.collapsingis added when the transition starts, and removed when it finishes
These classes tin can be constitute in component-animations.less.
Via data attributes
Just add together data-toggle="collapse" and a data-target to the element to automatically assign command of a collapsible chemical element. The data-target attribute accepts a CSS selector to employ the collapse to. Exist sure to add together the grade collapse to the collapsible chemical element. If you'd like information technology to default open up, add the additional class in.
To add squeeze box-like group direction to a collapsible control, add together the data attribute data-parent="#selector". Refer to the demo to come across this in activity.
Via JavaScript
Enable manually with:
$ ( '.collapse' ). plummet () Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to information-, as in data-parent="".
| Proper noun | blazon | default | clarification |
|---|---|---|---|
| parent | selector | false | If a selector is provided, then all collapsible elements under the specified parent will be closed when this collapsible particular is shown. (like to traditional piano accordion beliefs - this is dependent on the console class) |
| toggle | boolean | true | Toggles the collapsible element on invocation |
Methods
.collapse(options)
Activates your content as a collapsible element. Accepts an optional options object.
$ ( '#myCollapsible' ). collapse ({ toggle : false }) .collapse('toggle')
Toggles a collapsible chemical element to shown or hidden. Returns to the caller earlier the collapsible element has actually been shown or hidden (i.e. before the shown.bs.collapse or hidden.bs.collapse event occurs).
.collapse('evidence')
Shows a collapsible element. Returns to the caller earlier the collapsible chemical element has actually been shown (i.e. before the shown.bs.plummet event occurs).
.collapse('hide')
Hides a collapsible element. Returns to the caller earlier the collapsible element has actually been subconscious (i.eastward. before the hidden.bs.collapse event occurs).
Events
Bootstrap's collapse class exposes a few events for hooking into collapse functionality.
| Event Blazon | Description |
|---|---|
| testify.bs.collapse | This result fires immediately when the evidence instance method is called. |
| shown.bs.plummet | This event is fired when a collapse element has been made visible to the user (volition wait for CSS transitions to complete). |
| hide.bs.collapse | This event is fired immediately when the hide method has been called. |
| subconscious.bs.plummet | This event is fired when a collapse chemical element has been hidden from the user (will wait for CSS transitions to complete). |
$ ( '#myCollapsible' ). on ( 'hidden.bs.collapse' , role () { // do something… }) A slideshow component for cycling through elements, like a carousel. Nested carousels are not supported.
Examples
<div id= "carousel-example-generic" class= "carousel slide" data-ride= "carousel" > <!-- Indicators --> <ol class= "carousel-indicators" > <li data-target= "#carousel-example-generic" data-slide-to= "0" class= "agile" ></li> <li data-target= "#carousel-example-generic" information-slide-to= "1" ></li> <li data-target= "#carousel-example-generic" data-slide-to= "two" ></li> </ol> <!-- Wrapper for slides --> <div form= "carousel-inner" role= "listbox" > <div class= "detail active" > <img src= "..." alt= "..." > <div class= "carousel-explanation" > ... </div> </div> <div grade= "item" > <img src= "..." alt= "..." > <div grade= "carousel-caption" > ... </div> </div> ... </div> <!-- Controls --> <a form= "left carousel-control" href= "#carousel-case-generic" role= "push" information-slide= "prev" > <span course= "glyphicon glyphicon-chevron-left" aria-subconscious= "truthful" ></span> <span class= "sr-only" >Previous</bridge> </a> <a class= "correct carousel-control" href= "#carousel-example-generic" role= "button" data-slide= "next" > <bridge class= "glyphicon glyphicon-chevron-right" aria-hidden= "true" ></span> <span class= "sr-only" >Next</span> </a> </div> Accessibility issue
The carousel component is generally not compliant with accessibility standards. If you need to exist compliant, please consider other options for presenting your content.
Transition animations not supported in Internet Explorer 8 & ix
Bootstrap exclusively uses CSS3 for its animations, merely Cyberspace Explorer viii & 9 don't support the necessary CSS properties. Thus, there are no slide transition animations when using these browsers. We have intentionally decided not to include jQuery-based fallbacks for the transitions.
Initial active element required
The .active class needs to be added to 1 of the slides. Otherwise, the carousel will not be visible.
Glyphicon icons not necessary
The .glyphicon .glyphicon-chevron-left and .glyphicon .glyphicon-chevron-right classes are non necessarily needed for the controls. Bootstrap provides .icon-prev and .icon-next as plain unicode alternatives.
Optional captions
Add captions to your slides easily with the .carousel-explanation chemical element within any .detail. Place just about whatever optional HTML inside there and it will exist automatically aligned and formatted.
Get-go slide label
Nulla vitae elit libero, a pharetra augue mollis interdum.
Second slide label

Previous Next
<div form= "item" > <img src= "..." alt= "..." > <div course= "carousel-caption" > <h3>...</h3> <p>...</p> </div> </div> Usage
Multiple carousels
Carousels require the apply of an id on the outermost container (the .carousel) for carousel controls to function properly. When calculation multiple carousels, or when irresolute a carousel'southward id, be sure to update the relevant controls.
Via data attributes
Utilise data attributes to easily control the position of the carousel. information-slide accepts the keywords prev or side by side, which alters the slide position relative to its current position.

|---|---|
| slide.bs.carousel | This consequence fires immediately when the slide instance method is invoked. |
| slid.bs.carousel | This event is fired when the carousel has completed its slide transition. |
$ ( '#myCarousel' ). on ( 'slide.bs.carousel' , function () { // do something… }) Example
The braze plugin toggles position: fixed; on and off, emulating the effect institute with position: sticky;. The subnavigation on the right is a live demo of the braze plugin.
Usage
Apply the affix plugin via data attributes or manually with your own JavaScript. In both situations, y'all must provide CSS for the positioning and width of your affixed content.
Annotation: Exercise non use the braze plugin on an element contained in a relatively positioned element, such as a pulled or pushed cavalcade, due to a Safari rendering bug.
Positioning via CSS
The braze plugin toggles between iii classes, each representing a detail country: .affix, .affix-meridian, and .affix-bottom. You must provide the styles, with the exception of position: fixed; on .affix, for these classes yourself (independent of this plugin) to handle the bodily positions.
Here'south how the braze plugin works:
- To kickoff, the plugin adds
.affix-summitto point the element is in its top-virtually position. At this point no CSS positioning is required. - Scrolling past the element you want affixed should trigger the actual affixing. This is where
.affixreplaces.affix-topand setsposition: fixed;(provided by Bootstrap's CSS). - If a bottom offset is defined, scrolling past it should replace
.brazewith.affix-bottom. Since offsets are optional, setting ane requires you to set the appropriate CSS. In this case, add togetherposition: accented;when necessary. The plugin uses the data aspect or JavaScript option to determine where to position the element from there.
Follow the higher up steps to set your CSS for either of the usage options beneath.
Via data attributes
To hands add braze beliefs to any chemical element, just add data-spy="affix" to the element y'all want to spy on. Employ offsets to ascertain when to toggle the pinning of an chemical element.
<div data-spy= "braze" data-offset-top= "60" data-beginning-lesser= "200" > ... </div> Via JavaScript
Call the braze plugin via JavaScript:
$ ( '#myAffix' ). affix ({ beginning : { top : 100 , lesser : part () { render ( this . bottom = $ ( '.footer' ). outerHeight ( true )) } } }) Options
Options tin be passed via data attributes or JavaScript. For data attributes, suspend the pick name to information-, equally in data-offset-top="200".
| Proper name | type | default | description |
|---|---|---|---|
| starting time | number | function | object | x | Pixels to showtime from screen when calculating position of scroll. If a single number is provided, the get-go will be applied in both top and bottom directions. To provide a unique, bottom and top offset only provide an object commencement: { top: 10 } or offset: { top: 10, lesser: 5 }. Utilize a part when yous demand to dynamically calculate an start. |
| target | selector | node | jQuery element | the window object | Specifies the target element of the affix. |
Methods

$ ( '#myAffix' ). affix ({ offset : 15 }) .affix('checkPosition')
Recalculates the country of the affix based on the dimensions, position, and scroll position of the relevant elements. The .affix, .braze-top, and .braze-lesser classes are added to or removed from the affixed content according to the new state. This method needs to be chosen whenever the dimensions of the affixed content or the target element are changed, to ensure correct positioning of the affixed content.
$ ( '#myAffix' ). affix ( 'checkPosition' ) Events
Bootstrap's affix plugin exposes a few events for hooking into affix functionality.
| Event Blazon | Clarification |
|---|---|
| affix.bs.affix | This consequence fires immediately before the element has been affixed. |
