如何使用codeigniter中的onclick函数将id传递给控制器

Question

This is my code. I want to pass Id to use in the controller for delete

<button onclick="Delete(<?php echo $article->id; ?>)">Delete</button>

And this is function through which the id is passed to the controller

<script type="text/javascript">
    function Delete(id)
    {

      var conf=confirm('Are you want to delete');
      if (conf) 
      {
          $.ajax({
          url:'admin/delet_data',
          type:"post",
          data:{dlt_id:id},
          });
      }

    }
  </script>

I want the id in this function

 public function delet_data()
{
    echo $this->input->post('dlt_id'); exit;    
}

Answer 1

concatenate the id with url

js

 url:'admin/delet_data'+id,

then use function like this in controller

Controller

public function delet_data($id)
{
    echo $id;
}
