  <h2 id="buttons-examples">Example uses</h2>
  <p>Do more with buttons. Control button states or create groups of buttons for more components like toolbars.</p>

  <h4>Stateful</h4>
  <p>Add <code>data-loading-text="Loading..."</code> to use a loading state on a button.</p>
  <div class="bs-example" style="padding-bottom: 24px;">
    <button type="button" id="loading-example-btn" data-loading-text="Loading..." class="btn btn-primary">
      Loading state
    </button>
  </div><!-- /example -->
{% highlight html %}
<button type="button" id="loading-example-btn" data-loading-text="Loading..." class="btn btn-primary">
  Loading state
</button>
<script>
  $('#loading-example-btn').click(function () {
    var btn = $(this)
    btn.button('loading')
    $.ajax(...).always(function () {
      btn.button('reset')
    });
  });
</script>
{% endhighlight %}

  <h4>Single toggle</h4>
  <p>Add <code>data-toggle="button"</code> to activate toggling on a single button.</p>
  <div class="bs-example" style="padding-bottom: 24px;">
    <button type="button" class="btn btn-primary" data-toggle="button">Single toggle</button>
  </div><!-- /example -->
{% highlight html %}
<button type="button" class="btn btn-primary" data-toggle="button">Single toggle</button>
{% endhighlight %}

  <h4>Checkbox</h4>
  <p>Add <code>data-toggle="buttons"</code> to a group of checkboxes for checkbox style toggling on btn-group.</p>
  <div class="bs-callout bs-callout-warning">
    <h4>Pre-checked options need <code>.active</code></h4>
    <p>For pre-checked options, you must add the <code>.active</code> class to the input's <code>label</code> yourself.</p>
  </div>
  <div class="bs-callout bs-callout-warning">
    <h4>Visual checked state only updated on click</h4>
    <p>If the checked state of a checkbox button is updated without firing a <code>click</code> event on the button (e.g. via <code>&lt;input type="reset"&gt;</code> or via setting the <code>checked</code> property of the input), you will need to toggle the <code>.active</code> class on the input's <code>label</code> yourself.</p>
  </div>
  <div class="bs-example" style="padding-bottom: 24px;">
    <div class="btn-group" data-toggle="buttons">
      <label class="btn btn-primary active">
        <input type="checkbox" autocomplete="off" checked> Option 1 (pre-checked)
      </label>
      <label class="btn btn-primary">
        <input type="checkbox" autocomplete="off"> Option 2
      </label>
      <label class="btn btn-primary">
        <input type="checkbox" autocomplete="off"> Option 3
      </label>
    </div>
  </div><!-- /example -->
{% highlight html %}
<div class="btn-group" data-toggle="buttons">
  <label class="btn btn-primary active">
    <input type="checkbox" autocomplete="off" checked> Option 1 (pre-checked)
  </label>
  <label class="btn btn-primary">
    <input type="checkbox" autocomplete="off"> Option 2
  </label>
  <label class="btn btn-primary">
    <input type="checkbox" autocomplete="off"> Option 3
  </label>
</div>
{% endhighlight %}

  <h4>Radio</h4>
  <p>Add <code>data-toggle="buttons"</code> to a group of radio inputs for radio style toggling on btn-group.</p>
  <div class="bs-callout bs-callout-warning">
    <h4>Preselected options need <code>.active</code></h4>
    <p>For preselected options, you must add the <code>.active</code> class to the input's <code>label</code> yourself.</p>
  </div>
  <div class="bs-callout bs-callout-warning">
    <h4>Visual checked state only updated on click</h4>
    <p>If the checked state of a radio button is updated without firing a <code>click</code> event on the button (e.g. via <code>&lt;input type="reset"&gt;</code> or via setting the <code>checked</code> property of the input), you will need to toggle the <code>.active</code> class on the input's <code>label</code> yourself.</p>
  </div>
  <div class="bs-example" style="padding-bottom: 24px;">
    <div class="btn-group" data-toggle="buttons">
      <label class="btn btn-primary active">
        <input type="radio" name="options" id="option1" autocomplete="off" checked> Option 1 (preselected)
      </label>
      <label class="btn btn-primary">
        <input type="radio" name="options" id="option2" autocomplete="off"> Option 2
      </label>
      <label class="btn btn-primary">
        <input type="radio" name="options" id="option3" autocomplete="off"> Option 3
      </label>
    </div>
  </div><!-- /example -->

<div class="btn-group" data-toggle="buttons">

    <input type="radio" name="options" id="option1" autocomplete="off" checked> Option 1 (preselected)
  </label>
  <label class="btn btn-primary">
    <input type="radio" name="options" id="option2" autocomplete="off"> Option 2
  </label>
  <label class="btn btn-primary">
    <input type="radio" name="options" id="option3" autocomplete="off"> Option 3

  <h2 id="buttons-usage">Usage</h2>
  <p>Enable buttons via JavaScript:</p>
{% highlight js %}
$('.btn').button()
{% endhighlight %}

  <h3>Markup</h3>
  <p>Data attributes are integral to the button plugin. Check out the example code below for the various markup types.</p>

  <h3>Options</h3>
  <p><em>None</em></p>

  <h3>Methods</h3>

  <h4>$().button('toggle')</h4>
  <p>Toggles push state. Gives the button the appearance that it has been activated.</p>
  <div class="bs-callout bs-callout-info">
    <h4>Auto toggling</h4>
    <p>You can enable auto toggling of a button by using the <code>data-toggle</code> attribute.</p>
  </div>
{% highlight html %}
<button type="button" class="btn btn-primary" data-toggle="button">...</button>
{% endhighlight %}

  <h4>$().button('loading')</h4>
  <p>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 <code>data-loading-text</code>.
  </p>
{% highlight html %}
<button id="loading-example-btn" type="button" class="btn btn-primary" data-loading-text="loading stuff...">...</button>
<script>
  $('#loading-example-btn').click(function () {
    var btn = $(this)
    btn.button('loading')
    $.ajax(...).always(function () {
      btn.button('reset')
    });
  });
</script>
{% endhighlight %}

  <div class="bs-callout bs-callout-danger">
    <h4>Cross-browser compatibility</h4>
    <p><a href="https://github.com/twbs/bootstrap/issues/793">Firefox persists form control states (disabledness and checkedness) across page loads</a>. A workaround for this is to use <code>autocomplete="off"</code>.</p>
  </div>

  <h4>$().button('reset')</h4>
  <p>Resets button state - swaps text to original text.</p>

  <h4>$().button(string)</h4>
  <p>Resets button state - swaps text to any data defined text state.</p>
{% highlight html %}
<button type="button" class="btn btn-primary" data-complete-text="finished!" >...</button>
<script>
  $('.btn').button('complete')
</script>
{% endhighlight %}
