<body style="border:10px solid #ccc;padding:0px 0px;margin:5px 10px">
<div style="width:60%;border-right:1px dashed red;float:left;">
<div style="float:left;">
<div id="div1" style="border:5px red solid;height:300px;width:200px;overflow:auto">
<div style="height:500px;width:400px">请调整横竖滚动条后，点击按钮后查看offsetTop、offsetLeft、scrollTop、scrollLeft值。</div>
</div>
<input type="button" value="点击我!" onclick="req()" style="border: 1px solid purple;height: 25px;" />
</div>
</div>
<div style="width:30%;float:left;">
<ul style="list-style-type: none; line-height:30px;">
结果：
<li>offsetTop : <span id="li1"></span></li>
<li>offsetLeft : <span id="li2"></span></li>
<li> scrollTop : <span id="li3"></span></li>
<li>scrollLeft : <span id="li4"></span></li>
</ul>
</div>
<div style="clear:both;"></div>
<script>
function req() {
var div = document.getElementById("div1");
document.getElementById("li1").innerHTML = (div.offsetTop) + "px";//div1距离屏幕顶部的距离
document.getElementById("li2").innerHTML = (div.offsetLeft) + "px";//div1距离屏幕左部的距离
document.getElementById("li3").innerHTML = (div.scrollTop) + "px";//div1纵向滚动条滚动的距离
document.getElementById("li4").innerHTML = (div.scrollLeft) + "px";//div1横向滚动条滚动的距离
}
</script>
</body>
