offsetX property

Sets or retrieves the x-coordinate of a pointer's position relative to the object firing the event.

Syntax

JavaScript

p = object.offsetX

Property values

Type: Integer

the x-coordinate, in pixels.

Remarks

The property is read/write.

The coordinates match the offsetLeft and offsetTop properties of the object. Use offsetParent to find the container object that defines this coordinate system.

Examples

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.


<SCRIPT>
function offsetCoords()
{
    var offsetInfo = ""
    offsetInfo = "The x coordinate is: " + window.event.offsetX + "\r"
    offsetInfo += "The y coordinate is: " + window.event.offsetY + "\r"
    console.log(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>
