Retrieves the height of the object relative to the layout or coordinate parent, as specified by the offsetParent property.
Syntax
| JavaScript | |
|---|
Property values
Type: Integer
the height, in pixels.
Remarks
You can determine the location, width, and height of an object by using a combination of the offsetLeft, offsetTop, offsetHeight, and offsetWidth properties. These numeric properties specify the physical coordinates and dimensions of the object relative to the object's offset parent.
For more information about how to access the dimension and location of elements on the page through the Dynamic HTML (DHTML) Document Object Model (DOM), see Measuring Element Dimension and Location with CSSOM in Internet Explorer 9.
Examples
This example adjusts the size of a clock's readout to fit the current width and height of the document body.
<html>
<head>
<title>A Simple Clock</title>
<script language="JavaScript">
function startClock()
{
window.setInterval("Clock_Tick()", 1000);
Clock_Tick();
}
var iRatio = 4;
function Clock_Tick()
{
var dToday = Date();
var sTime = dToday.substring(11,19);
var iDocHeight = document.body.offsetHeight;
var iDocWidth = document.body.offsetWidth;
if ((iDocHeight*iRatio)>iDocWidth)
iDocHeight = iDocWidth / iRatio;
document.all.MyTime.innerText = sTime;
document.all.MyTime.style.fontSize = iDocHeight;
}
</script>
</head>
<body onload="startClock()">
<p id="MyTime"> </p>
</body>
</html>
This example uses the offsetHeight property and the clientHeight property to show different ways of measuring the object size.
<div id="oDiv" style="overflow: scroll; width: 200; height: 100"> . . . </div> <button onclick="console.log(oDiv.clientHeight)">client height</button> <button onclick="console.log(oDiv.offsetHeight)">offset height</button>
