程序代码：

<script>
//获得对像绝对位置
var divtop,divleft
function getIE(e){
    var objtop=e.offsetTop;
    var objleft=e.offsetLeft;
    while(e=e.offsetParent)    {
        objtop+=e.offsetTop;
        objleft+=e.offsetLeft;
    }
    divtop = objtop
    divleft = objleft
}
//参考对象处显示对象位置,绝对位置
function Odiv(obj,div,yplace,xplace){
    getIE(obj)
    if (div.style.display=="none"){
        div.style.left = divleft + xplace;
        div.style.top = divtop + yplace;
        div.style.display = "";
    }else{
        div.style.display = "none"
    }
}
</script>
<a href="####" onclick="Odiv(this,ddd,0,0)">点我</a>
<div id="ddd" style="position:absolute;display:none; border:1px solid #000; width:200px; height:200px">我出来了</div>
