This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The offsetX read-only property of the MouseEvent interface provides the offset in the X coordinate of the mouse pointer between that event and the padding edge of the target node.
Syntax
var xOffset = instanceOfMouseEvent.offsetX;
Return value
A double floating point value. Early versions of the spec defined this as an integer. See the Browser compatibility section for details.
