js实现变换图片flash

以下是js代码,我测试了,还不错

<div id="divs">
<img src="images/flash1.jpg" id="1" style="FILTER: revealTrans(duration=1,transition=16); cursor:pointer;" onclick="location.href = '#'">
<img src="images/flash2.jpg" id="2"   style="FILTER: revealTrans(duration=1,transition=17); cursor:pointer;display:none" onclick="location.href = '#'">
<img src="images/flash3.jpg" id="3"   style="FILTER: revealTrans(duration=1,transition=18); cursor:pointer;display:none" onclick="location.href = '#'">
<img src="images/flash4.jpg" id="4"   style="FILTER: revealTrans(duration=1,transition=19); cursor:pointer;display:none" onclick="location.href = '#'">
<img src="images/flash5.jpg" id="5"   style="FILTER: revealTrans(duration=1,transition=20); cursor:pointer;display:none" onclick="location.href = '#'">
<img src="images/flash6.jpg" id="6"   style="FILTER: revealTrans(duration=1,transition=21); cursor:pointer;display:none" onclick="location.href = '#'">
</div>

<script language="javascript">
function $(_sId) {
    return document.getElementById(_sId);
}
var speed=5000;
var setid=null;
var auto="true";
function galleryplay(divs,a,mtime){ //t为要应用此函数的id，a初始化时显示的项目的顺序数
    if(divs=="0")return false;
    var start=3;
    if(auto=="true")
    {
        start = a-1;//初始项目
        speed = mtime;//切换间隔
        setid = null;//定时器
        var loop = function(){ //自动切换
            ids = divs.split(",");
            for (var i=0;i<ids.length; i++)
            {
                 $(ids[i]).style.display='none';

            }
            $(ids[start]).filters.revealTrans.Transition = Math.floor(Math.random() * 23);
            $(ids[start]).filters.revealTrans.apply();
            $(ids[start]).filters.revealTrans.play();
            $(ids[start]).style.display='';

            setid=setTimeout(loop,speed);
            start++;
            if(start==ids.length){
                start=0;
            }
        };loop();
    }
}
galleryplay('1,2,3,4,5,6',1,5000);
</script>
