function getDim(el)
{
for (var lx=0,ly=0; el!=null; lx+=el.offsetLeft,ly+=el.offsetTop,el=el.offsetParent);
return {x:lx,y:ly}
}
//创建遮挡层
function createLayer(el)
{
myImgDim = getDim(el);

document.writeln("<div id='Layer1' style='position:absolute; z-index:1; left: "+myImgDim.x+"px; top: "+myImgDim.y+"px;'>");
