求一段实现几个页面在iframe中每隔几秒钟自动跳转

setInterval(location.href=ar[i>length-1?0:i++],5000);只是写个意思,代码自己写吧

  1.   

    <html>
    <head>
        <script>
            $ = function (id) {
                return document.getElementById(id);
            };
            
            var url = [];
            
            url.push ('http://www.baidu.com');
            url.push ('http://www.google.com');
            url.push ('http://www.csdn.cn');
            
            var count = 0;
            
            function changeSrc (ifr) {
                var iframe = $(ifr);
                
                if (count >= url.length) count = 0;
                
                iframe.src = url[count];
                
                count ++;
            }
            
            setInterval("changeSrc('iframe1')",3000);
        </script>
    </head>
    <body>
        <iframe id="iframe1" src="http://www.baidu.com"></iframe></body>
    </html>
      

  2.   

    <script language="JavaScript">
    <!--
    //设置版块跳转的路径,多个类此
    var bq1={"1.htm","2.htm","3.htm"};
    var bq2={"11.htm","22.htm","33.htm"};var i=j=0;//各个版块的计数变量;
    var time=5000;//5秒跳转;//跳转函数,counter为相应版块的计数变量
    function jump(iframeName,bqArr,counter)
    {
    if(counter<bqArr.length)
    {
    iframeName.location.href=bq1[i];
    counter++;
    }
    else
    {
    iframeName.location.href=bq1[0];
    counter=0;
    }
    }
    //调用
    window.setInterval(jump("iframe1",bq1,i),time);
    window.setInterval(jump("iframe2",bq2,j),time);
    //-->
    </script>
