Click Anywhere Pop Up - popup

Question

I'm trying to create a popup (new window) that appears when a person clicks anywhere on the page , but the problem is that my script creates a new tab for every click . I created a blogspot account just for test : http://faqetest123.blogspot.al/
what should I do for that ?
(example of a site that is using the popup that im trying to create is :atdhe.so)
Here is my code :
<script type="text/javascript">
document.onclick=function()
{
window.open('http://www.facebook.com');
}
</script>
Thanks

The window.open() function returns a reference to that window. So you should be able to use that reference to navigate to a new URL at a later time. Something like this:
var myPopup;
document.onclick=function()
{
if (!myPopup) {
myPopup = window.open('http://www.facebook.com');
} else if (myPopup.closed) {
myPopup = window.open('http://www.google.com');
} else {
myPopup.location.href = 'http://www.stackoverflow.com';
}
}
Note that this also attempts to check if the user has closed the pop-up and re-opens it.
Edit: Based on your comments below, it looks like I misunderstood. In order to have the popup execute once and then not again, you can simply remove the event handler after processing it. Something like this:
document.onclick=function()
{
window.open('http://www.facebook.com');
document.onclick = null;
}
