This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
The non-standard, read-only
pageX returns the horizontal coordinate of the event relative to the whole document.
This property was never part of any standard, and was only implemented across a subset of browsers, and only for a limited number of versions. A standardized version of
pageX was added to the
MouseEvent interface, however, and is well-supported. You should not expect to find
pageX on any non-mouse events. Do not look for
pageX on any non-mouse events in new code and update existing code as soon as possible.
var pos = event.pageX
An integer value, in pixels, indicating the X coordinate at which the mouse pointer was located when the event occurred. This value is relative to the left edge of the entire document, regardless of the current horizontal scrolling offset of the document.
For an example, see the documentation for the standard
MouseEvent.pageX property, which you should use instead.
This property is not part of any specification. See
