[jQuery] Form plugin, add loading gif

[hubbs]

I am trying to add a loading gif to the form plugin, but each time I
do, it breaks.

I am using:

$(document).ready(function() {

//Create function for ajax asset builder
$('#page_asset_builder_28031').ajaxForm({
  iframe: true,
  success: function(html) {
  $("#loading").show();
  $("#ajaxResult").html($(html).find("#ajaxResponse"));
  $("#loading").hide();
  }});

});

I need to get the   $("#loading").hide(); statement moved up further
in the script, so that it gets activated right when the submit button
is clicked, rather on success, but when I create a function, and do
this, it seems to not work.

Any ideas?
