UIEvent.pageX

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The UIEvent.pageX read-only property returns the horizontal coordinate of the event relative to the whole document.

Syntax

var pos = event.pageX

Examples

var pageX = event.pageX;

pageX is an integer value in pixels for the X coordinate of the mouse pointer, relative to the whole document, when the mouse event fired. This property takes into account any horizontal scrolling of the page.
