I have an HTML as follow :

   <table class="responsive display table table-bordered">
    <tbody>
     <tr>
       <th>Sr No</th>
       <th>Student Code</th>

          <i class="icon-trash"></i>
        </a>
      </td>
      <td>
        <input name="deleteselect[]" value="2" type="checkbox">
      </td>
    </tr>
    <tr>
      <td>2</td>
      <td>1003</td>
      <td>Lisa Kurdow </td>
      <td>24-7-1965</td>
      <td> &nbsp;&nbsp;&nbsp;&nbsp;<a href="http://localhost/wordpress/wp-admin/admin.php?page=eMarksheet-student-list&amp;action=update&amp;id=6" rel="tooltip" title="update" class="update"><i class="icon-pencil"></i></a> &nbsp;&nbsp; <a href="http://localhost/wordpress/wp-admin/admin.php?page=eMarksheet-student-list&amp;action=delete&amp;id=6" onclick="return show_confirm();" rel="tooltip" title="Delete" class="delete"><i class="icon-trash"></i></a></td><td><input name="deleteselect[]" value="6" type="checkbox"></td></tr>
    </tbody></table>

I have a select all checkbox with id checkAll What I want is that when I click on this checkbox then it should select/deselect all the remaining check box in table

I have used the code :

<script type="text/javascript">
jQuery(document).ready(function (){
   $("#checkAll").change(function () {
    $("input:checkbox").prop('checked', $(this).prop("checked"));
});
});
</script>

But when I click on selectAll checkbox then it does not select the checkboxes. Please help me what is missing in it ?

Answer 1

If you get jQuery(...).prop not a function error, it means you are using an old version of jQuery ( < 1.6 ). Very old, it is recommended to update the jQuery. Use this code then:

<script type="text/javascript">
  jQuery(document).ready(function (){
    jQuery("#checkAll").change(function () {
      if (this.checked)
        jQuery("input:checkbox").attr('checked', "checked");
      else
        jQuery("input:checkbox").removeAttr('checked');
    });
  });
</script>

You can use bellow code. I tested it's working fine.

  $(document).ready(function(){ $("#checkAll").change(function () { $("input:checkbox").attr('checked', this.checked); }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script> <table class="responsive display table table-bordered"> <tbody> <tr> <th>Sr No</th> <th>Student Code</th> <th>Student Name</th> <th>Date Of Birth</th> <th>Action</th> <th>Select&nbsp;&nbsp;&nbsp;<a data-placement="left" rel="tooltip" title="Select All"><input id="checkAll" name="deleteselect[]" value="0" type="checkbox"></a></th> </tr> <form action="" method="post"></form> <tr> <td>1</td> <td>1001</td> <td>Rohit Singhal </td> <td>17-4-1988</td> <td> &nbsp;&nbsp;&nbsp;&nbsp; <a href="http://localhost/wordpress/wp-admin/admin.php?page=eMarksheet-student-list&amp;action=update&amp;id=2" rel="tooltip" title="update" class="update"> <i class="icon-pencil"></i> </a> &nbsp;&nbsp; <a href="http://localhost/wordpress/wp-admin/admin.php?page=eMarksheet-student-list&amp;action=delete&amp;id=2" onclick="return show_confirm();" rel="tooltip" title="Delete" class="delete"> <i class="icon-trash"></i> </a> </td> <td> <input name="deleteselect[]" value="2" type="checkbox"> </td> </tr> <tr> <td>2</td> <td>1003</td> <td>Lisa Kurdow </td> <td>24-7-1965</td> <td> &nbsp;&nbsp;&nbsp;&nbsp;<a href="http://localhost/wordpress/wp-admin/admin.php?page=eMarksheet-student-list&amp;action=update&amp;id=6" rel="tooltip" title="update" class="update"><i class="icon-pencil"></i></a> &nbsp;&nbsp; <a href="http://localhost/wordpress/wp-admin/admin.php?page=eMarksheet-student-list&amp;action=delete&amp;id=6" onclick="return show_confirm();" rel="tooltip" title="Delete" class="delete"><i class="icon-trash"></i></a></td><td><input name="deleteselect[]" value="6" type="checkbox"></td></tr> </tbody></table>
