A jQuery plugin which allows you to quickly add check all/uncheck all functionality to your forms or tables.

Download / Fork

Source is available on GitHub.

Setup

Include jQuery and the script somewhere on your page.

<script src="jquery.js"></script>
<script src="jquery-check-all.js"></script>

You'll have markup which contains your checkboxes, for example:

<table>
  <thead>
    <tr>
      <td><input id="check-all" type="checkbox"></td>
      <td></td>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td><input type="checkbox" value="1"></td>
      <td>option 1</td>
    </tr>
    <tr>
      <td><input type="checkbox" value="2"></td>
      <td>option 2</td>
    </tr>
    <tr>
      <td><input type="checkbox" value="3"></td>
      <td>option 3</td>
    </tr>
  </tbody>
</table>

Call the checkAll() function on your "check all" checkbox to initialize the plugin.

<script>
  $(document).ready(function() {
    $('#check-all').checkAll();
  });
</script>

Options

The plugin can be supplied with an options object to further filter which checkboxes you want to group.

var options = { container: $('#table'), showIndeterminate: true };
$('#check-all-box').checkAll(options);

Alternatively, options may be supplied via data attributes. Note that options passed via the options object will override any options specified via data attributes.

<input id="check-all" type="checkbox" data-show-indeterminate="true">

Available options:

• container: A selector string or jQuery object of the element which contains the children checkboxes. Defaults to document.
• childCheckboxes: A selector string or jQuery object of the children checkboxes. Defaults to input[type=checkbox]. Note: if you supply this option, make sure what you're passing are checkboxes.
• showIndeterminate: a boolean which specifies whether to display the check all checkbox in the indeterminate state if a subset of the children checkboxes are selected.

Requirements

• jQuery 1.7+/2.0+
