删除按钮在CodeIgniter中不起作用

Question

Here's my Delete button:

<td>
    <a href="javascript:void(0);" onclick="delete(<?php echo $data->emp_id;?>);">
        <button id="button_delete">Delete</button>
    </a>
</td>

Here's my Javascript code:

<script type="text/javascript">
    var url="<?php echo base_url();?>";
    function delete(id)
    {
        var r=confirm("Do you want to delete this employee?");
        if (r==true)
        {
            window.location = url+"index.php/admin_logins/employee4/"+id;
        }
        else
        {
            return false;
        }
    }
</script>

Here's my controller (admin_logins.php) method -

function employee4($emp_id)
{
    $this->employee_model->delete_employee($emp_id);
    $this->index();
}

And here's my model(employee_model.php) method -

public function delete_employee($emp_id)
{
    $this->db->where('employee.emp_id',$emp_id);
    return $this->db->delete('employee');
}

My table name is employee and my database is MySQL.

Column Name         Datatype
   id                 int
  emp_id             varchar(15)
  emp_name           varchar(50)
  emp_mobile_no      varchar(15)

Whenever I click the Delete button, nothing happens. What am I doing wrong?

Answer 1

It's the function name delete I tested it and gave me this error:

Uncaught SyntaxError: Unexpected token delete

So try to name it with another name, ex: deleteEntry or deleteEmployee

delete is the javascript command so it's reserved word, and please always avoid to name functions or variables with reserved words

Alternatively I suggest to use the solution:

<td>
    <a href="index.php/admin_logins/employee4/<?php echo $data->emp_id;?>" 
       onclick="return confirm('Do you want to delete this employee?');">
        <button id="button_delete">Delete</button>
    </a>
</td>

Give a tags href, and onclick just return confirmation message
