Need to calculate offsetRight in javascript
- by Dan Bailiff
I need to calculate the offsetRight of a DOM object. I already have some rather simple code for getting the offsetLeft, but there is no javascript offsetRight property. If I add the offsetLeft and offsetWidth, will that work? Or is there a better way?
function getOffsetLeft(obj)
{
if(obj == null)
return 0;
var offsetLeft = 0;
var tmp = obj;
while(tmp != null)
{
offsetLeft += tmp.offsetLeft;
tmp = tmp.offsetParent;
}
return offsetLeft;
}
function getOffsetRight(obj)
{
if (obj == null)
return 0;
var offsetRight = 0;
var tmp = obj;
while (tmp != null)
{
offsetRight += tmp.offsetLeft + tmp.offsetWidth;
tmp = tmp.offsetParent;
}
return offsetRight;
}
