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.
