I have the following function in my header:

1. <script type="text/javascript">
   
   function updateWithAlpha() {
   $("#casestudy").load("alpha.html");
   };
   
   </script>
   
   
   
   
   
   
   

The function is called immediately when the page loads.  I don't want it called immediately.  I only want it to work when a link is clicked.  The link works with this function.  Though, why is being called when the page loads?
thanks
