Add scrollParent() method to detect the scrolling parent

[paul]

Similar to how jQuery.fn.offsetParent works, this function returns the immediate scrolling parent.

This means in detail, the first element in parents() that has one of the following css attributes set to auto or scroll: overflow, overflow-x, overflow-y.

It's especially useful in anything collision detection related - 10+ instances in jQuery UI, for example could be made a lot shorter.

I'm not sure this would be useful for the common jQuery user. If it's needed in UI, maybe it'd be better to add that to UI.

Can you provide a couple of non-UI related applications ?

[paul]

Collision detection means:

1) Any tooltip plugin 2) Any menu plugin

In other words, any usecase where you have an element and you need to control and check in what logical container it sits in - that is always the scrollParent.

[flesler]

tooltip and menu seem like UI to me. Any non-UI test cases.

[paul]

There are hundreds of plugins that create similar functionality that are not part of jQuery UI - or are you talking of the generic term "user interface"?

If you're talking not specifically about jQuery UI, then your argument is almost pointless - jQuery is always used to alter/create an UI.
