Call load() function after ajax Success

I am trying to do a partial page re-load after my ajax POST returns successful. I have tried putting the load() function in the Success callback but it never gets triggered. I know it's not a problem with the load() function itself because I can run it in the console and it works fine. How do I run it on success? Thanks.

        $("#saveNewTask").click(function () {
            $.ajax({
                cache: false,
                url: url,
                data: data,
                type: "POST",
                error: function (e) {
                    console.log(e);
                    alert("Error creating new task");
                },
                success: function (response) {
                    $('#mainTaskWrapper').load('/Tasks #mainTaskWrapper');
                }
            });
        });

I got it figured out. I was making a dumb mistake. The ajax call was in an iframe and the element was in the parent doc. I had to select
#mainTaskWrapper

Open in new window

like
$('#mainTaskWrapper', window.parent.document)

Open in new window

Are you certain that the success clause is being invoked? Have you placed an alert or console.log statement in the success clause to confirm that it is being invoked? There are situations in which neither the error or success clause will be invoked.

Nothing wrong with the code
Sample
HTML
<button id="saveNewTask">Save</button>
<div id="mainTaskWrapper"></div>

Open in new window

jQuery
$(function() {
  url = 'reflect.php';
  data = {test: 'test'};
  $("#saveNewTask").click(function () {
    $.ajax({
      cache: false,
      url: url,
      data: data,
      type: "POST",
      error: function (e) {
        console.log(e);
        alert("Error creating new task");
      },
      success: function (response) {
        $('#mainTaskWrapper').load('t1685data.html #mainTaskWrapper');
      }
    });
  });
});

Open in new window

Load HTML [t1685data.html]
<!doctype html>
<html>
<body>
<p>This is outside of the load zone</p>
<div id="mainTaskWrapper">This is the content that will be displayed</div>
<p>This is outside of the load zone</p>
</body>
</html>

Problem must be elsewhere - what are you seeing in the console.
