offsetParent property

Retrieves a reference to the container object that defines the offsetTop and offsetLeft properties of the object.

Syntax

JavaScript

p = object.offsetParent

 

Property values

Type: Object

the container object.

Remarks

Most of the time the offsetParent property returns the body object.

Examples

This example shows how to determine the position of a td object. Although the td object appears to the far right in the document, its position is close to the x-axis and y-axis, because its offset parent is a table object rather than the document body.


<html>

<head>
<title>Elements: Positions</title>
<script type="text/javascript">

  function showPosition()
  {
    var oElement = document.all.oCell;
    
    console.log("The TD element is at (" + oElement.offsetLeft + 
          "," + oElement.offsetTop + ")\n" + "The offset parent is " 
          + oElement.offsetParent.tagName );
  }
  </script>
</head>

<body onload="showPosition()">

<p>This document contains a right-aligned table.
<table align="right" border="1">
	<tr>
		<td id="oCell">This is a small table.</td>
	</tr>
</table>
</p>

</body>

</html>
