About modals

A streamlined, but flexible, take on the traditional javascript modal plugin with only the minimum required functionality and smart defaults.

Download file

Static example

Below is a statically rendered modal.

Live demo

Toggle a modal via javascript by clicking the button below. It will slide down and fade in from the top of the page.

Launch demo modal

Using bootstrap-modal

Call the modal via javascript:

$('#myModal').modal(options)

Options

Name type default description
backdrop boolean true 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 key is pressed
show boolean true Shows the modal when initialized.

Markup

You can activate modals on your page easily without having to write a single line of javascript. Just set data-toggle="modal" on a controller element with a data-target="#foo" or href="#foo" which corresponds to a modal element id, and when clicked, it will launch your modal.

Also, to add options to your modal instance, just include them as additional data attributes on either the control element or the modal markup itself.

<a class="btn" data-toggle="modal" href="#myModal" >Launch Modal</a>
<div class="modal hide" id="myModal">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal">×</button>
    <h3>Modal header</h3>
  </div>
  <div class="modal-body">
    <p>One fine body…</p>
  </div>
  <div class="modal-footer">
    <a href="https://b8y.nengqian.cn/" class="btn" data-dismiss="modal">Close</a>
    <a href="https://s.nengqian.cn/" class="btn btn-primary">Save changes</a>
  </div>
</div>
Heads up! If you want your modal to animate in and out, just add a .fade class to the .modal element (refer to the demo to see this in action) and include bootstrap-transition.js.

Methods

.modal(options)

Activates your content as a modal. Accepts an optional options object.

$('#myModal').modal({
  keyboard: false
})

.modal('toggle')

Manually toggles a modal.

$('#myModal').modal('toggle')

.modal('show')

Manually opens a modal.

$('#myModal').modal('show')

.modal('hide')

Manually hides a modal.

$('#myModal').modal('hide')

Events

Bootstrap's modal class exposes a few events for hooking into modal functionality.

Event Description
show This event fires immediately when the show instance method is called.
shown This event is fired when the modal has been made visible to the user (will wait for css transitions to complete).
hide This event is fired immediately when the hide instance method has been called.
hidden This event is fired when the modal has finished being hidden from the user (will wait for css transitions to complete).
$('#myModal').on('hidden', function () {
  // do something…
})


This plugin adds quick, dynamic tab and pill functionality for transitioning through local content.

Using bootstrap-tab.js

Enable tabbable tabs via javascript (each tab needs to be activated individually):

$('#myTab a').click(function (e) {
  e.preventDefault();
  $(this).tab('show');
})

You can activate individual tabs in several ways:

$('#myTab a[href="#profile"]').tab('show'); // Select tab by name
$('#myTab a:first').tab('show'); // Select first tab
$('#myTab a:last').tab('show'); // Select last tab
$('#myTab li:eq(2) a').tab('show'); // Select third tab (0-indexed)

Markup

You can activate a tab or pill navigation without writing any javascript by simply 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.

<ul class="nav nav-tabs">
  <li><a href="#home" data-toggle="tab">Home</a></li>
  <li><a href="#profile" data-toggle="tab">Profile</a></li>
  <li><a href="#messages" data-toggle="tab">Messages</a></li>
  <li><a href="#settings" data-toggle="tab">Settings</a></li>
</ul>

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.

<ul class="nav nav-tabs" id="myTab">
  <li class="active"><a href="#home">Home</a></li>
  <li><a href="#profile">Profile</a></li>
  <li><a href="#messages">Messages</a></li>
  <li><a href="#settings">Settings</a></li>
</ul>
<div class="tab-content">
  <div class="tab-pane active" id="home">...</div>
  <div class="tab-pane" id="profile">...</div>
  <div class="tab-pane" id="messages">...</div>
  <div class="tab-pane" id="settings">...</div>
</div>
<script>
  $(function () {
    $('#myTab a:last').tab('show');
  })
</script>

Events

Event Description
show This event fires on tab show, but before the new tab has been shown. Use event.target and event.relatedTarget to target the active tab and the previous active tab (if available) respectively.
shown This event fires on tab show after a tab has been shown. Use event.target and event.relatedTarget to target the active tab and the previous active tab (if available) respectively.
$('a[data-toggle="tab"]').on('shown', function (e) {
  e.target // activated tab
  e.relatedTarget // previous tab
})

About Tooltips

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 data-attributes for local title storage.

About

Do more with buttons. Control button states or create groups of buttons for more components like toolbars.

Download file

Example uses

Use the buttons plugin for states and toggles.

Stateful
Single toggle
Checkbox
Radio

Using bootstrap-button.js

Enable buttons via javascript:

$('.nav-tabs').button()

Markup

Data attributes are integral to the button plugin. Check out the example code below for the various markup types.

<!-- Add data-toggle="button" to activate toggling on a single button -->
<button class="btn" data-toggle="button">Single Toggle</button>
<!-- Add data-toggle="buttons-checkbox" for checkbox style toggling on btn-group -->
<div class="btn-group" data-toggle="buttons-checkbox">
  <button class="btn">Left</button>
  <button class="btn">Middle</button>
  <button class="btn">Right</button>
</div>
<!-- Add data-toggle="buttons-radio" for radio style toggling on btn-group -->
<div class="btn-group" data-toggle="buttons-radio">
  <button class="btn">Left</button>
  <button class="btn">Middle</button>
  <button class="btn">Right</button>
</div>

Methods

$().button('toggle')

Toggles push state. Gives the button the appearance that it has been activated.

Heads up! You can enable auto toggling of a button by using the data-toggle attribute.
<button class="btn" data-toggle="button" >…</button>

$().button('loading')

Sets button state to loading - disables button and swaps text to loading text. Loading text should be defined on the button element using the data attribute data-loading-text.

<button class="btn" data-loading-text="loading stuff..." >...</button>
Heads up! Firefox persists the disabled state across page loads. A workaround for this is to use autocomplete="off".

$().button('reset')

Resets button state - swaps text to original text.

$().button(string)

Resets button state - swaps text to any data defined text state.

<button class="btn" data-complete-text="finished!" >...</button>
