我是否正确地将值从jquery传递给我的控制器？

Question

I am doing a delete on a table using jquery,

$('table#chkbox td a.delete').click(function()
    {
        if (confirm("Are you sure you want to delete this row?"))
        {
            var id = $(this).parent().attr('id');

            var parent = $(this).parent().parent();

            $.ajax(
            {
                   type: "POST",
                   url: "<?php echo base_url().'index.php/libraryController/librarydelete' ?>",
                   data: { 'id': id },
                   cache: false,

                   success: function()
                   {
                        parent.fadeOut('slow', function() {$(this).remove();});
                   }
             });                
        }
    });

I am getting the id value correctly but my data parameter doesn't get passed to my controller,

function librarydelete($id)
{
$del = $id;
echo $del; 
$this->librarymodel->deletebook_issue($id);
$this->session->set_flashdata('response','Deleted successfully');
redirect('libraryController/loadmagazinedetails');
}

Any suggestion...

I am getting the error,

Missing argument 1 for libraryController::librarydelete() and Undefined variable: id

Your are posting the data, so you can get the id like this:

function librarydelete()
{
    $del = $_POST['id'];
    echo $del; 
    $this->librarymodel->deletebook_issue($_POST['id']);
    $this->session->set_flashdata('response','Deleted successfully');
    redirect('libraryController/loadmagazinedetails');
}

Looks like you are using codeigniter, so this would be even better:

$del = $this->input->post('id');
