Get Left Position of Control

JavaScript function to Get the Left Position of any control.
Pass the control ID for which you want to calculate the left position.

function LeftPos(ctrlID, pos)
{
var leftCoord = 0;
while(ctrlID)
{
leftCoord += ctrlID.offsetLeft;
ctrlID= ctrlID.offsetParent;
}
return leftCoord + pos;
}
