Question

How to get the scroll position value of a document?

Answer 1

Here's how to get the scrollHeight of an element obtained using a jQuery selector:

$(selector)[0].scrollHeight

If selector is the id of the element (e.g. elemId), it is guaranteed that the 0-indexed item of the array will be the element you wish to select, and scrollHeight will be correct.
