question about style.height

[datactrl]

Hi, all

If I didn't set the height of an html element on a web page with html
attributes. Then obj.style.height always reports "0" even after the page has
completely rendered. Is there any way to get the actual height after being
rendered?

The following code will get the computed height in pixels:

var obj = document.getElementById("myObject");
var objHeight = null;
if(document.implementation.hasFeature("CSS", "2.0")) {
objHeight = document.defaultView.getComputedStyle(obj,
null).getPropertyCSSValue("height").getFloatValue(5);
}
else if(obj.clientHeight!=null) {
objHeight = obj.offsetHeight;
}
