关于时间有效期
一个订单有个有效期40分钟 入库的时候开始读 用户可以查看订单 在页面上会显示最新的时间
比如入库过去5分钟40秒 然后查询出这个订单 会有一个时间在读 剩34分20秒 等到入库后40分钟后
状态会变为失效 这个要怎么实现啊 求高手 大虾指教啊

这样?

还有你说的那个页面刷新对这个没影响的
[解决办法]
那就应该是倒计时代码了，给你参考一下：
<form name="form1"> <div align="center" align="center"> <center>离2010年还有:<br> <input type="textarea" name="left" size="35" style="text-align: center"> </center> </div> </form> <script LANGUAGE="javascript"> startclock() var timerID = null; var timerRunning = false; function showtime() { Today = new Date(); var NowHour = Today.getHours(); var NowMinute = Today.getMinutes(); var NowMonth = Today.getMonth(); var NowDate = Today.getDate(); var NowYear = Today.getYear(); var NowSecond = Today.getSeconds(); if (NowYear <2000) NowYear=1900+NowYear; Today = null; Hourleft = 23 - NowHour Minuteleft = 59 - NowMinute Secondleft = 59 - NowSecond Yearleft = 2009 - NowYear Monthleft = 12 - NowMonth - 1 Dateleft = 31 - NowDate if (Secondleft<0) { Secondleft=60+Secondleft; Minuteleft=Minuteleft-1; } if (Minuteleft<0) { Minuteleft=60+Minuteleft; Hourleft=Hourleft-1; } if (Hourleft<0) { Hourleft=24+Hourleft; Dateleft=Dateleft-1; } if (Dateleft<0) { Dateleft=31+Dateleft; Monthleft=Monthleft-1; } if (Monthleft<0) { Monthleft=12+Monthleft; Yearleft=Yearleft-1; } Temp=Yearleft+'年, '+Monthleft+'月, '+Dateleft+'天, '+Hourleft+'小时, '+Minuteleft+'分, '+Secondleft+'秒' document.form1.left.value=Temp; timerID = setTimeout("showtime()",1000); timerRunning = true; } var timerID = null; var timerRunning = false; function stopclock () { if(timerRunning) clearTimeout(timerID); timerRunning = false; } function startclock () { stopclock(); showtime(); } // --> </script>
