offsetX Property
Retrieves the x-coordinate of the mouse pointer's position relative to the object firing the event.
Syntax
HTML N/A Scripting [ iCoord = ] event.offsetX
Possible Values
iCoord Integer that specifies the x-coordinate, in pixels. The property is read-only with no default value.
Remarks
The coordinates match the offsetLeft and offsetTop properties of the object. Use offsetParent to find the container object that defines this coordinate system.
Example
This example uses the offsetX property to determine the mouse position relative to the container that fired the event, and displays the mouse coordinates in the status bar at the bottom of the window.
Sample Code
<SCRIPT> function offsetCoords() { var offsetInfo = "" offsetInfo = "The x coordinate is: " + window.event.offsetX + "\r" offsetInfo += "The y coordinate is: " + window.event.offsetY + "\r" alert(offsetInfo); } </SCRIPT> </HEAD> <BODY onmousemove="window.status = 'X=' + window.event.offsetX + ' Y=' + window.event.offsetY" ondblclick="offsetCoords()"> : <DIV onclick="offsetCoords();" . . . position:absolute; top:200; left:300;"> : </DIV>
