图片自动切换不能执行，敬请帮忙

代码如下，为啥不能图片切换，请指教，谢谢！！！var imgUrl=new Array();
var imgLink=new Array();
var adNum=0;
imgUrl[1]='upfiles/qyzz2.jpg';
imgLink[1]='upfiles/qyzz2.jpg';
imgUrl[2]='upfiles/qyzz1.JPG';
imgLink[2]='upfiles/qyzz1.jpg';
imgUrl[3]='upfiles/qyzz3.jpg';
imgLink[3]='upfiles/qyzz3.jpg';
imgUrl[4]='upfiles/qyzz4.jpg';
imgLink[4]='upfiles/qyzz4.jpg';
var j=0;
for (i=1;i<=4;i++) {
if( (imgUrl[i]!='') && (imgLink[i]!='') ) {
j++;
} else {
break;
}
}
var imgPre=new Array();
function playTran()
{
if (document.all)
imgInit.filters.revealTrans.play();
}
var key=0;
function nextAd(){
if(adNum<j)adNum++ ;
else adNum=1;
if( key==0 ){
key=1;
} else if (document.all){
imgInit.filters.revealTrans.Transition=6;
imgInit.filters.revealTrans.apply();
playTran();
}
document.images.imgInit.src=imgUrl[adNum];
theTimer=setTimeout('nextAd()', 6000);
}
function goUrl(){
jumpUrl=imgLink[adNum];
jumpTarget='_blank';
if (jumpUrl != ''){
if (jumpTarget != '') 
window.open(jumpUrl,jumpTarget);
else
location.href=jumpUrl;
}
}
document.write ('<a href="javascript:goUrl()"><img style="FILTER: revealTrans(duration=2,transition=20);border:0px;" src="javascript:nextAd()" width=240 height=170 border=1 class=img01 name=imgInit></a>')

  1.   

    在IE7下测试没有问题。
    间隔时间比较长，
    你可以试一下下面的sample.<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

                function playTran(){
                    if (document.all)

  2.   

    又测试了一下，确实是有问题。
    IE单独执行的时候不好用。
    src="javascript:nextAd()"中的函数不能执行。
    你这样改一下吧。<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    上面兄弟，你的办法仍然不能自动切换，迷惑。
    我是在.net2003环境中运行的，但在asp环境下可以自由切换，迷惑！！！
