I have an anchor link inside a div. I would like both the anchor link and div to process onclick events separately, but right now clicking on the anchor link also triggers the onclick event for the div. How do I prevent this?

Here's the code:

```

<html>
     <head>
     <style>
     #box {
          background-color: #ccffcc;
          width: 400px;
          height: 200px;
     }
     </style>
     <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js">
     </script>
     <script type="text/javascript">
          $(document).ready(function() {
               $("#mailto").click(function(event) {
                    // correctly opens an email client if clicked
                    $("a[@href^='http']").attr('target','_blank');
                    return( false );
               });

               $("#box").click(function() {
                    // always goes to the home page, even if the #mailto id is clicked
                    window.location = '/index.php';
               });
          });
     </script>
     </head>
     <body>
     <div id="box">
          <a  href="mailto:someone@psomewhere.com" id="mailto">someone@psomewhere.com
    </div>
     </body>
</html>

```

Is there a way for me to stop execution of the code after the mailto is loaded?

Thanks!

John
