附注：
方法1：
function getAbsPoint(e)
{
var x = e.offsetLeft, y = e.offsetTop;
while(e=e.offsetParent)
{
x += e.offsetLeft;
y += e.offsetTop;
}
alert("x:"+x+","+"y:"+y);
}
方法2：
function getAbsPoint(obj)
{
var x,y;
orect = obj.getBoundingClientRect();
x=oRect.left
y=oRect.top
alert("("+x+","+y+")")
}
JS中获得窗口属性的方法
1。获得屏幕的分辨率：
screen.width
screen.height
2。获得窗口大小：
document.body.clientWidth
document.body.clientHeight
3。获得窗口大小（包含Border、Scroll等元素）
document.body.offsetWidth
