JS Event Listeners

[hybrid kill3r]

So, I have a javascript function that when a user clicks on a link with this attached, it opens a confirmation asking if they want to continue. But instead of using onclick everytime I want to use it, I want to use something like rel="confirm" on the anchor. How would I do this?

function confirmAction(hyperlink){    if(confirm(("Are you sure you want to do this?  This action CANNOT be undone!!!")){	    	    window.location = hyperlink;	        } else {	    	    return false;        }}

After the page is loaded, loop through every <a> element using document.getElementsByTagName(). If the "rel" property is "confirm" then attach an event listener to the link.
