刚刚写的 JS 全屏广告代码..
4秒后下拉显示 ..然后上拉隐藏..
<script type="text/javascript">
var intervalId = null;
function slideAd(id,nStayTime,sState,nMaxHth,nMinHth){
this.stayTime=nStayTime*3000 || 9000;
this.maxHeigth=nMaxHth || 712;
this.minHeigth=nMinHth || 1;
this.state=sState || "down" ;
var obj = document.getElementById(id);
if(intervalId != null)window.clearInterval(intervalId);
function openBox(){
var h = obj.offsetHeight;
obj.style.height = ((this.state == "down") ? (h + 3) : (h - 3))+"px";
if(obj.offsetHeight>this.maxHeigth){
window.clearInterval(intervalId);
intervalId=window.setInterval(closeBox,this.stayTime);
}
if (obj.offsetHeight<this.minHeigth){
window.clearInterval(intervalId);
obj.style.display="none";
}
}
function closeBox(){
slideAd(id,this.stayTime,"up",nMaxHth,nMinHth);
}
intervalId = window.setInterval(openBox,10);
}
</script>
</head>
<body>
<div id="MyMoveAd" style="height:12px; width:960px; margin:0 auto;overflow:hidden;">
<img src="61.jpg" />
</div>
<script type="text/javascript">
<!--
function openimg(){
slideAd('MyMoveAd',2);
}
setTimeout(openimg,4000)
-->
</script>
</body>
