About modals

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

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.

Using bootstrap-modal

Call the modal via javascript:

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

Options

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://M.5491.com.cn/" class="btn" data-dismiss="modal">Close</a>
    <a href="https://YET.5491.com.cn/" class="btn btn-primary">Save changes</a>
  </div>

About dropdowns

Add dropdown menus to nearly anything in Bootstrap with this simple plugin. Bootstrap features full dropdown menu support on in the navbar, tabs, and pills.

Examples

Click on the dropdown nav links in the navbar and pills below to test dropdowns.

Using bootstrap-dropdown.js

Call the dropdowns via javascript:

Markup

To quickly add dropdown functionality to any element just add data-toggle="dropdown" and any valid bootstrap dropdown will automatically be activated.

<ul class="nav nav-pills">
  <li class="active"><a href="https://ocw.5491.com.cn/">Regular link</a></li>
  <li class="dropdown" id="menu1">
    <a class="dropdown-toggle" data-toggle="dropdown" href="#menu1">
      Dropdown
      <b class="caret"></b>
    </a>
    <ul class="dropdown-menu">
      <li><a href="https://ocw.5491.com.cn/">Action</a></li>
      <li><a href="https://ocw.5491.com.cn/">Another action</a></li>
      <li><a href="https://ocw.5491.com.cn/">Something else here</a></li>

      <li><a href="https://ocw.5491.com.cn/">Separated link</a></li>
    </ul>
  </li>
  ...
</ul>

To keep URLs intact, use the data-target attribute instead of href="https://ocw.5491.com.cn/".

<ul class="nav nav-pills">
  <li class="dropdown">
    <a class="dropdown-toggle" data-toggle="dropdown" data-target="#" href="https://ocw.5491.com.cn/path/to/page.html">
      Dropdown
      <b class="caret"></b>
    </a>
    <ul class="dropdown-menu">
      ...
    </ul>
  </li>
</ul>

Methods

$().dropdown()

A programatic api for activating menus for a given navbar or tabbed navigation.

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

Example tabs

Click the tabs below to toggle between hidden panes, even via dropdown menus.

• Home
• Profile
• Dropdown
  • @fat
  • @mdo

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

  <li><a href="#profile">Profile</a></li>
  <li><a href="#messages">Messages</a></li>
