php jQuery动态下拉列表

Question

I am having problem sending/reading ajax variable.

Ajax code is as below:

$.ajax({
    url: "/wp-content/themes/canvas-child/get-clients-dropdown.php?it=1",
    success: function(data) {
        $("#ClientID").html(data);
    }
});

I have tried to read it in another php file like this:

$InvoiceType = $_REQUEST['it'];
//$InvoiceType = $_POST['it'];
//$InvoiceType = $_GET['it'];

But none of above works. The variable $InvoiceType always stays empty.

What is the problem?

Answer 1

$.ajax({
      type: "GET",
      data: {it: "1"}, 
      url: "/wp-content/themes/canvas-child/get-clients-dropdown.php?it=1",
      success: function(data) {
         $("#ClientID").html(data);
      }
});

try this
