<HEAD>
<TITLE> JS獲取DIV相對坐標</TITLE>
<script type="text/javascript"><!--
function getX(obj){
var parObj=obj;
var left=obj.offsetLeft;
while(parObj=parObj.offsetParent){
left+=parObj.offsetLeft;
}
return left;
}
function getY(obj){
var parObj=obj;
var top=obj.offsetTop;
while(parObj = parObj.offsetParent){
top+=parObj.offsetTop;
}
return top;
}
function DisplayCoord(event){
var top,left,oDiv;
oDiv=document.getElementById("demo");
top=getY(oDiv);
left=getX(oDiv);
document.getElementById("mp_x").innerHTML = (event.clientX-left+document.documentElement.scrollLeft) -2+"px";
document.getElementById("mp_y").innerHTML = (event.clientY-top+document.documentElement.scrollTop) -2+"px";
}
// --></script>
</HEAD>
<BODY mce_style="margin:40px;">
<div onmousemove="DisplayCoord(event)">
