<body style="width:2000px; height:1000px;">
<div id="demo" style="position:absolute; left:518px; right:100px; width:500px; height:500px; background:#CC0000; top: 114px;">Demo为了方便就直接用绝对定位的元素</div>
</body>
</html>
<script>
document.getElementById('demo').onclick=function (){
if (document.documentElement.getBoundingClientRect) {
alert("left:"+this.getBoundingClientRect().left)
alert("top:"+this.getBoundingClientRect().top)
alert("right:"+this.getBoundingClientRect().right)
alert("bottom:"+this.getBoundingClientRect().bottom)
var
X=
this.getBoundingClientRect().left+document.documentElement.scrollLeft;
var Y =
this.getBoundingClientRect().top+document.documentElement.scrollTop;
alert("Demo的位置是X:"+X+";Y:"+Y)
}
}
</script>
有了这个方法,获取页面元素的位置就简单多了,
var X=
this.getBoundingClientRect().left+document.documentElement.scrollLeft;
var Y =this.getBoundingClientRect().top+document.documentElement.scrollTop;
