本文实例讲述了JS实现兼容各种浏览器的高级拖动方法。分享给大家供大家参考，具体如下：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>高级拖动</title>
<style>
#toBeDraged{
width:100px;
height:100px;
line-height:100px;
border:1px solid red;
position:absolute;
text-align:center;
font-family:Arial, Helvetica, sans-serif;
cursor:move;
}
</style>
<script type= "text/javascript">
window.onload = function(){
doDrag();
}
function doDrag(){
var div = document.getElementById("toBeDraged");
var posx;
var posy;
div.onmousedown = function(e){
var e = e || window.event;
if (div.setCapture) {
div.setCapture();
}
posx = e.clientX - parseInt(div.offsetLeft);
posy = e.clientY - parseInt(div.offsetTop);
document.onmousemove = function(ev){
var ev = ev || window.event;//如果是IE
if (ev.setcapture) {
}
div.style.left = (ev.clientX - posx)+"px";
div.style.top = (ev.clientY - posy)+"px";
}
document.onmouseup = function(){
document.onmousemove = null;
document.onmouseup = null;
if (div.releaseCapture) {
div.releaseCapture();
}
}
}
}
</script>
</head>
<body>
<div id = "toBeDraged">你拖我啊!</div>
</body>
</html>
希望本文所述对大家JavaScript程序设计有所帮助。
