Here is a previous method of doing a popunder.
Code:
var Popup = {

var ret = originalHandler(e);
if (typeof(ret) == "undefined" || ret == "") ret = handler(e);
return ret;
};
} else {
target["on" + eventName] = handler;
}
} else if (target.addEventListener) {
target.addEventListener(eventName, handler, false);
} else if (target.attachEvent) {
target.attachEvent("on" + eventName, handler);
} else {
var originalHandler = target["on" + eventName];
if (originalHandler) {
target["on" + eventName] = function(e) {
originalHandler(e);
handler(e);
};
} else {
target["on" + eventName] = handler;
}
}
},
