<script><!--var tSeconds=0;var tMinutes=0;var tHours=0;var timer=null;function schedule(hours,minutes,seconds){ tHours = hours; tMinutes = minutes; tSeconds = seconds; //TODO check.. run();}function run(){ var date=new Date(); if((date.getMinutes()-tMinutes==0) &&(date.getSeconds()-tSeconds==0) &&(date.getHours()-tHours==0)){ toDo(); window.clearTimeout(timer); }else{ timer = window.setTimeout("run()",1); }}function toDo(){ //Add your operation here alert('do some thing');}--></script>
<body οnlοad="schedule(20,15,00)">
备注：
1、shedule(20,15,00)之间的数字代表小时,分钟,秒
2、function toDo(){ //Add your operation here alert('do some thing');}
这函数里面即为你要运行的函数。如果想运行后台函数：
1)先在前台建立个按钮<asp:Button ID="Button1" runat="server" Text="获取数据" οnclick="Button1_Click" />；
2)在后台Button1_Click里编写你所需运行的功能；
3)在前台JS里toDo()函数中调用按钮函数：
function toDo(){ //Add your operation here document.getElementById("Button1").click(); }
以上方法均测试过，未发现问题。
