代码如下：
<script> <!-- var limit="0:10" if (document.images){ var parselimit=limit.split(":") parselimit=parselimit[0]*60+parselimit[1]*1 } function beginrefresh(){ if (!document.images) return if (parselimit==1) window.location.reload() else{ parselimit-=1 curmin=Math.floor(parselimit/60) cursec=parselimit%60 if (curmin!=0) curtime=curmin+"分"+cursec+"秒后重刷本页！" else curtime=cursec+"秒后重刷本页！" window.status=curtime setTimeout("beginrefresh()",1000) } } window.onload=beginrefresh file://--> </script>
