JSON uploading stringified html

[leslie]

I want to upload a whole user-updated html div, to later download again. This is what I put in the header of the html (it gave no errors, but doesn't upload either):

<script type="text/javascript">
 $(document).ready(function(){	 document.onbeforeunload = function {	
content = $('#content').html();
  $.post(url, {jsonData: JSON.stringify(content) }, function(response){$('#changelist').text(response);  }); 
   }
  )};
 })
</script>

What am I missing? Thanks!

url is not defined and the page likely is somewhere else should the AJAX response arrive.
