今天遇到的问题：IE6/7返回offsetTop没有计算body的margin

function GetRealOffset(o)
{

        var elem = o;
        var leftOffset = elem.offsetLeft;
        var topOffset = elem.offsetTop;
        var parent = elem.offsetParent;

        while(parent)
        {
             leftOffset += parent.offsetLeft;
             topOffset += parent.offsetTop;
            parent = parent.offsetParent;
        }
        var Offsets = new Object();
        Offsets.top = topOffset;
        Offsets.left = leftOffset;

        return Offsets;
}
