Action confirmation with JavaScript

Just a simple little trick for confirming with a user before they undertake an action on your web page. Sometimes you need to confirm things. You know, does the user of your site really want to delete that file FOREVER, or not. You can do it the hard way with a catch page to confirm, but the easier way is to use JavaScript.

Just like this:

<a href="irrevocable-action.php?doitnow=yes" onclick="return confirm('Are you really, really, really sure you want to do this?')">Do It!!</a>

When the user clicks the link, they will hit a pop up box, displaying the confirmation message and two buttons. If they click yes the link is followed and the action completed, otherwise they stay on the page and nothing happens.
