[Javascript] Bubbling and canceling events

[Philip Thompson]

Hi all.

In the application I'm working on, I keep coming back to this similar  
problem. I'll just show you here...

<table>
<tr onclick="goToUrl('viewuser.php?user_id=1');">
   <td>Johnny Appleseed</td>
   <td>12/3/1981</td>
   <td><a href="javascript:printCard();">Print Card</a></td>
</tr>
<table>

Ok, let's say the user clicks on "Print Card". This is a javascript  
function that performs some AJAX-related things in the background (in  
this case, prints a card). After clicking to print, I wish nothing  
more to happen - I wish to cancel the set of events that follow. In  
this case, I want to cancel the call to the javascript function  
goToUrl() as specified in the <tr> element - I do not want to visit  
the view user page. To accomplish this, I attempted the following:

function printCard () {
   if (!e) var e = window.event;
   e.cancelBubble = true;
   if (e.stopPropagation) e.stopPropagation();

   //... do stuff here
}

However, it still redirects me!! Ahhhh! I can't handle it anymore. Is  
there anyway to cancel the redirection/events? I would be greatly  
appreciated if someone could shed some much-needed light.

Thanks in advance,
~Philip

Note: this is a somewhat simplified example of the real thing.
