window.onload=function () { var lunboimg = document.getElementById('lunbo').getElementsByTagName('div'); var n=0; function lunbofun() { for (var i=0;i<lunboimg.length;i++){ lunboimg[i].style.display='none'; } lunboimg[n].style.display='block'; } function start(){ n++; if (n>=lunboimg.length) { n=0; } lunbofun(); } setInterval(start,3000); }
