Question on a jquery function

Question on a jquery function

I'm trying to run a function that executes a spinner while a PHP script is loading and also refreshes a PHP file that counts the number of rows inserted to show the script's progress.

This is what I have so far:

  2.  <script type="text/javascript" language="javascript">
  3. // start spinner on button click
  4.    $(document).ajaxSend(function(spinner) {
  5. $("#spinner").show();
  6. }
  7. );

  9. // refresh progress script and output to #content div
  10. function updateProgress(){
  11.     $('#content').load('progress.php');
  12. }
  13. myTimer = setInterval( "updateProgress()", 2000 );

  15. // Execute the primary function
  16.    $(document).ready(function() {
  17.       $("#driver").click(function(event){
  18.           $('#stage').load('execute.php');
  19.       });
  20.    });
  21.  
  22. // hide spinner and content div when finished
  24. $(document).ajaxStop(function(spinner) {
  25. clearInterval(myTimer);
  26. $("#spinner").fadeOut("fast");
  27. $("#content").fadeOut("fast");
  28. });
  29.    </script>
