今天在维护集团网站的时候，也出现了 'bannerADrotator未定义'的错误！
网上搜了一下，也有朋友出现这个问题，也有解决方法，拷过去以备用！
出现错误的源码：
var bannerAD=new Array();
var bannerADlink=new Array();
var adNum=0;
bannerAD[0]="Image/1.jpg"
bannerADlink[0]="http://www.sina.com/";
bannerAD[1]="Image/2.jpg"
bannerADlink[1]="http://www.it365cn.com/";
bannerAD[2]="Image/3.jpg"
bannerADlink[2]="http://www.163.com/";
bannerAD[3]="Image/4.jpg"
bannerADlink[3]="http://www.sohu.com/";
var preloadedimages=new Array();
for (i=1;i<bannerAD.length;i++){
preloadedimages[i]=new Image();
preloadedimages[i].src=bannerAD[i];
}
function setTransition(){
if (document.all){
bannerADrotator.filters.revealTrans.Transition=Math.floor(Math.random()*23);
bannerADrotator.filters.revealTrans.apply();
}
}
function playTransition(){
if (document.all)
bannerADrotator.filters.revealTrans.play()
}
function nextAd(){
if(adNum<bannerAD.length-1)adNum++ ;
else adNum=0;
setTransition();
document.images.bannerADrotator.src=bannerAD[adNum];
playTransition();
theTimer=setTimeout("nextAd()", 5000);
}
function jump2url(){
jumpUrl=bannerADlink[adNum];
jumpTarget='_blank';
if (jumpUrl != ''){
if (jumpTarget != '')window.open(jumpUrl,jumpTarget);
else location.href=jumpUrl;
}
}
function displayStatusMsg() {
status=bannerADlink[adNum];
document.returnValue = true;
}
