Events

Event Propagation

Note All events are propagated to and from input element to the toggle.

You should listen to events from the <input type="checkbox"> directly rather than look for custom events.

<input id="toggle-event" type="checkbox" data-toggle="toggle">
<div id="console-event"></div>
<script>
  $(function() {
    $('#toggle-event').change(function() {
      $('#console-event').html('Toggle: ' + $(this).prop('checked'))
    })
  })
</script>

API vs Input

This also means that using the API or Input to trigger events will work both ways.

<input id="toggle-trigger" type="checkbox" data-toggle="toggle">
<button class="btn btn-success" onclick="toggleApiOn()" >On by API</button>
<button class="btn btn-danger"  onclick="toggleApiOff()">Off by API</button>
<button class="btn btn-success" onclick="toggleInpOn()" >On by Input</button>
<button class="btn btn-danger"  onclick="toggleInpOff()">Off by Input</button>
<script>
  function toggleApiOn() {
    $('#toggle-trigger').bootstrapToggle('on')
  }
  function toggleApiOff() {
    $('#toggle-trigger').bootstrapToggle('off')  
  }
  function toggleInpOn() {
    $('#toggle-trigger').prop('checked', true).change()
  }
  function toggleInpOff() {
    $('#toggle-trigger').prop('checked', false).change()
  }
</script>
