<script>
<!--
var limit="0:45"
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+"秒后刷新"

else

curtime=cursec+"秒后刷新"

window.status=curtime

setTimeout("beginrefresh()",1000)

}

}

window.onload=beginrefresh
