View Page...The javascript is called when the

<div class="multiple_del" title="Delete"><img src="../../images/minus.png"/></div>
                </div>

    <table border="0"  cellpadding="0" style="width:100%;margin:0px auto" cellspacing="0" id="product-table">
                    <thead>
                        <tr>
                        <th class="tbl_hdr sorter-false"><img src="../../images/trash.png" style="padding-left:13px;"/></th><!--Multiple Delete--->
                        <th class="tbl_hdr">USER ID</th> <!--ID-->                    
                        <th class="tbl_hdr">‫NAME</th> <!--Name-->

                        <th class="tbl_hdr">PHONE NUMBER‎</th> <!--ph number-->
                        <th class="tbl_hdr sorter-false">STATUS</th> <!--publish/unpublish-->
                        <th class="tbl_hdr sorter-false" colspan="2">ACTION</th> <!--edit/delte-->

                       <a class="status published" value="<?php echo $user->id;?>" title="Published"></a>

                       </td>
                       </tr>    
                       <?php $count++;}?> 
                    </tbody>    
                    </table>
<div>
                <div class="multiple_del" title="Delete"><img src="../../images/minus.png"/></div>
                </div>

Javascript...

    $(document).ready(function(){

       $('.multiple_del').click(function(){
                var checkValues = $('input[name=checkboxlist]:checked').map(function()
                {
                    return $(this).val();
                }).get();
                //alert(checkValues);
                var url='<?php echo base_url(); ?>index.php/admin/delete_multiple';

                $.ajax({

                    type: 'POST',
                    url: url,
                    data: { ids: checkValues },
                    success:function(data)
                    {

                          window.location="<?php echo base_url(); ?>index.php/admin/users";
                          $( ".msg1" ).text( "Selected Users Deleted..!!");
                    }
                });

       });





});

Controller...The ajax url goes to this controller

public function delete_multiple()//Delete Multiple Users
      {

        $ids=$this->input->post('ids');
        $this->admin_model->delete_multiple($ids);

      }

Model...

function delete_multiple($ids)//Delete Multiple Users
    {

     $this->db
          ->where_in('id', $ids)
          ->delete('tbl_users');

    }

changing the checkbox name does not call the javascript...its not giving me the value of selected checkboxes in alert box — rinku simlai

You need to adjust your javascript according to name="checkboxlist[]". I would suggest reviewing question - stackoverflow.com/questions/9493531/… — Kamall A Joshi
