获取一个DIV的绝对坐标的功能函数,即使是非绝对定位,一样能获取到
function getElCoordinate(dom) {
var t = dom.offsetTop;

dom=dom.offsetParent;
while (dom) {
t += dom.offsetTop;
l += dom.offsetLeft;
dom=dom.offsetParent;
}; return {
top: t,left: l
};

//兼容各种浏览器的,获取鼠标真实位置
function mousePosition(ev){
if(!ev) ev=window.event;
if(ev.pageX || ev.pageY){
return {x:ev.pageX,y:ev.pageY};
}
return {
x:ev.clientX + document.documentElement.scrollLeft - document.body.clientLeft,y:ev.clientY + document.documentElement.scrollTop - document.body.clientTop
};
