jQuery load php file (and send a value)?

[Hintswen]

Trying to load insert.php?id=#### into a div on the page

#### is a number that is from a form here's my code:

The form:
<form id="Add_Form" method="post">
ID: <input class="text" type="text" name="ID" value="<?php echo $_GET['id']; ?>" />
<input class="inputbutton" type="submit" /></form>

jQuery stuff:
$(document).ready(function(){
$("#Add_Form").submit(function() {
var ID = $('#ID').attr('value');
$("#Add_Load").get("insert.php", { "ID": ID } );
return false;
});
});
