js问题
<script language="JavaScript" type="text/JavaScript">var imgUrl=new Array();
var imgLink=new Array();
var adNum=0;
imgUrl[1]="../pic/1.jpg";
imgLink[1]="http://192.168.0.241/index/movie.asp?id=23226";
imgUrl[2]="../pic/4.jpg";
imgLink[2]="http://192.168.0.241/index/movie.asp?id=25312";

imgUrl[4]="../pic/4.jpg";
imgLink[4]="http://192.168.0.241/index/movie.asp?id=23226";
imgUrl[5]="../pic/5.jpg";
imgLink[5]="http://192.168.0.241/index/movie.asp?id=23226";
var imgj=0;
for (imgi=1;imgi<=5;imgi++) {
if( (imgUrl[imgi]!="") && (imgLink[imgi]!="") ) {
imgj++;
} else {
break;
}
}
function playTran(){
if (document.all)
imgInit.filters.revealTrans.play();
}
var key=0;
function nextAd(){
if(adNum<imgj)adNum++ ;
else adNum=1;
if( key==0 ){
key=1;
} else if (document.all){
imgInit.filters.revealTrans.Transition=23;
imgInit.filters.revealTrans.apply();
playTran();
}
document.images.imgInit.src=imgUrl[adNum];
theTimer=setTimeout("nextAd()", 8000);
}
function goUrl(){
jumpUrl=imgLink[adNum];
jumpTarget='_blank';
if (jumpUrl != ''){
if (jumpTarget != '')
window.open(jumpUrl,jumpTarget);
else
location.href=jumpUrl;
}
}
</script>
<a href="javascript:goUrl()"><img style="FILTER: revealTrans(duration=3,transition=20);" src="javascript:nextAd()" width=482 height=357 border=0 name=imgInit></a></div></td>
谁可以帮我详细的解释下这代码么。？
js我一点不会！
