本文实例讲述了JS实现物体带缓冲的间歇运动效果。分享给大家供大家参考，具体如下：
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="content-type" charset="utf-8" />
<meta http-equiv="content-type" content="text/html" />
<title>demo</title>
</head>
<body>
<div id="odiv" style="position:absolute;width:200px;height:100px;background:red;left:0;border:1px solid #333;"></div>
<script type="text/javascript">
var odiv=document.getElementById('odiv');
odiv.onmouseover=function(){
move(this,'width',500,function(){
move(odiv,'left',300,function(){
move(odiv,'height',500,function(){
move(odiv,'borderWidth',10)
});
});
});
}
function move(obj,arr,target,fn){
clearInterval(obj.dt);
obj.dt=setInterval(function(){
obj.ol=parseInt(obj.style[arr]);
if(obj.ol==target){
clearInterval(obj.dt);
if(fn) fn();
}else{
obj.speed=(target-obj.ol)/8;
obj.speed>0?obj.speed=Math.ceil(obj.speed):obj.speed=Math.floor(obj.speed);
obj.style[arr]=obj.ol+obj.speed+"px";
}
},30);
}
</script>
</body>
</html>
希望本文所述对大家JavaScript程序设计有所帮助。
