[jQuery] setTimeout / clearTimeout question...

[gr00vy0ne]

This is more of a general javascript question but when using
setTimeout and clearTimeout, does the "timer" variable have to exist
outside the function globally?

For instance, I understand the following:

var t;

$(".some_link").hover(function() {
    clearTimeout(t)
    $("#this_layer").show();
}, function() {
    t = setTimeout(function() {$("#this_layer").hide()}, 2000);
}

Is there a way to create the timer within the jquery hover so that
it's self-contained? Ideally, I'd like the timer to be dynamically
created as necessary so if I add other hovers then I don't need to
keep adding new variables to store the timer.

Would I have to create an array that stores each unique timer? Is that
the way to go?
