Popup windows

Whats the code to setup pop up windows? I've got a page that I want to say Happy Birthday but I want it to popup different windows with messages; sort of like those popup ads.

Give this a try (in your head tag...you can change the width and height numbers, etc)P

Code:

---

<script language="JavaScript">
<!--
function popupWindow(url) { window.open(url,'popup','width=395,height=330,menubar=no,scrollbars=yes,toolbar=no,location=no,directories=no,resizable=no,top=50,left=50'); }
//-->
</script>

---

Then, this wherever you would like the link to active the window appear

Code:

---

<a href="" onClick="popupWindow('page.html'); return false;" onMouseOver="window.status='Click to Launch Popup!'; return true;" onMouseOut="window.status='';">
Click to Launch Popup!</a>

---

Hope that helps. :)
