Rails spinoffs - Jun 2007 - Prototype: How to display a div placed in browser window on long page?

Hi

I want to put an "edit item" div on a pretty long item list.
How to make it always visible in the browser even if the list will be
scrolled? (aka CSS: fixed property)

Thanks

Piotr

1) Get the y position of the DIV
2) window.scrollTo(0, y)

I use the following to do this:

var myPos = findPos($(''someDIV''))
window.scrollTo(0, myPos[1])

function findPos(obj) {
	var curleft = curtop = 0;
	if (obj.offsetParent) {
		curleft = obj.offsetLeft
		curtop = obj.offsetTop
		while (obj = obj.offsetParent) {
			curleft += obj.offsetLeft
			curtop += obj.offsetTop
		}
	}
	return [curleft,curtop];
}
