I am just trying to get this javascript to decipher between internal and external links, and in the event it is an internal link I would like to override the popup script so the visitors aren't bugged with a popup on every clicked internal link.

I found some code on here that is...



function checkUrl(href) {
leaving = ((href.indexOf("://") > -1) || (href.indexOf("www.") > -1));
}


...but I couldn't get it to work with my script. Please help! Thanks guys, and girls!

There are at least two problems here. The code at the bottom of your post won't work. All links will pass that test, even those to your own site. That's one, the other is when/how to use it if it did work.

Forget about whether the link is local or not for a moment. Let's say we prevent the user from leaving and present this new content and they do everything we ask of them. Then they go to leave for real, can they?

In any case, this code can tell which type of link was clicked:


(function(){
var links = {
addEvent: (function(){return window.addEventListener? function(el, ev, f){
el.addEventListener(ev, f, false);
}:window.attachEvent? function(el, ev, f){
el.attachEvent('on' + ev, f);
}:function(){return;};
})(),
check: function(e){
e = e || event;
var t = e.target || e.srcElement;
if(t == t.href && t.href.indexOf(loc) > -1){ //link is local
window.leaving = false;
} else { //link is off site
window.leaving = true;
}
}
}, loc = location.host.replace(/www./, '');
links.addEvent(window, 'load', function(){
var a = document.getElementsByTagName('a');
for (var i = a.length - 1; i > -1; --i){
links.addEvent(a[i], 'click', links.check);
}
});
})();

It will react before unload, even before beforeunload, so the leaving variable will be set for use in your other functions.
