I'm using jQuery to sort a list of entries, between <LI></LI> tags, and then an Ajax post to validate the order and 'update' the page with the content returned.
$.ajax({url: "./test.php?id=<?php echo $id; ?>&action=modify",
contenttype: "application/x-www-form-urlencoded;charset=utf-8",
data: {myJson: data},
type: 'post',
success: function(data) {
$('html').html(data);
OnloadFunction ();
}
});
Then, I lose the ability to sort the list (I'm not sure if clear...). I tried to move the content of the $(document).ready inside the OnloadFunction (), and call it with <script>OnloadFunction ();</script> inside the block dealing with the modifications to do :
$action= $_GET['action'];
if ($action == "modify") {
// Code here
}
but it doesn't work...
I can't figure out how to do that. Could anyone help ?
I stripped out the main part of the code to keep only the essential (filename: test.php)
