elementFromPoint method
The elementFromPoint()
method, available on the Document object, returns the topmost Element
at the specified coordinates
(relative to the viewport).
If the element at the specified point belongs to another document (for
example, the
document of an iframe), that document's parent element is returned
(the <iframe> itself). If the element at the given point is anonymous
or XBL generated content, such as a textbox's scroll bars, then the first
non-anonymous
ancestor element (for example, the textbox) is returned.
Elements with set to none will be ignored,
and the element below it will be returned.
If the method is run on another document (like an <iframe>'s
subdocument), the coordinates are relative to the document where the
method is being
called.
If the specified point is outside the visible bounds of the document or
either
coordinate is negative, the result is null.
If you need to find the specific position inside the element, use Document.caretPositionFromPoint.
