Obsolete
This feature is obsolete.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 UIEvent property 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.

Syntax

var pos = event.pageX

Value

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.

Examples

For an example, see the documentation for the standard MouseEvent.pageX property, which you should use instead.

Specifications

This property is not part of any specification. See MouseEvent.pageX instead.
