Question

I want to track a variable as I navigate around my site. How can I use jQuery to output this value without having to worry about tracking down wherever it might be affected and having it update.

var num = 1;

$(#trackvariable).text(num)  

I want the above to execute constantly as it were.. I don’t necessarily want to do it on a timer. Is there any way to do that?

If you want to listen to changes on a textnode, you can do something like this:

function InitListener () {
    var container = document.getElementById ("textContainer");
    var textNode = container.firstChild;
    if (textNode.addEventListener) {
        textNode.addEventListener ('DOMCharacterDataModified', OnCharacterModified, false);
    }
}
