I am wondering how I can get the amount of pixels (or measurement in general) from a div to the top of the window in Javascript. I am not looking for an offset y in relation to the document, simply to the top of where the browser is displaying. I tried the "answered" solution here: http://stackoverflow.com/questions/211703/is-it-possible-to-get-the-position-of-div-within-the-browser-viewport-not-with, but at least in Safari, I am running into a problem where it returns the same number no matter where the div's really are.

感谢您的帮助！

This answer tells you how to get the x and y coords of an element with respect the origin (top left) of a document. You just need to add the .scrollTop value to the y coord to get the distance in pixels from div to top of viewport.
