JQuery offset () prototype equivalent

Question

I would like to know if there is any prototype equivalent to the JQuery.offset () function?

Thank you for your help.

Answer 1

jQuery offset (element position relative to the document) is mapped to Element.cumulativeOffset

similarly, the jQuery position (element position relative to the offset parent) is displayed in Element.positionedOffset

Answer 2

If you are looking for an offset relative to the document, go for:

Element.cumulativeOffset

If you are looking for an offset relative to an element, go for:

Element.Offset.
