 InterValObj = window.setInterval(SetRemainTime, 1000); //間隔函數(shù)，1秒執(zhí)行

當(dāng)我們在webservice里讀取到數(shù)據(jù)庫中的時間字段后，把時間分割判斷。Javascript代碼如下：

<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
function Times() {
var tempTime=document.getElementById("currTime").innerHTML.split(":");
var hour=tempTime[0];
var minute=tempTime[1];
var second=tempTime[2];
if(second>=1)
{
second=(second-1>9)?(second-1):"0"+(second-1);
}
else
{
  second="59";
   if(minute>=1){
     minute=(minute-1>9)?(minute-1):"0"+(minute-1);
   }else{
    minute="59";
     if(hour>=1){
      hour=(hour-1>9)?(hour-1):"0"+(hour-1);
     }else{
      minute="00";
      hour="0"+0;
     }
   }
}
document.getElementById("currTime").innerHTML=hour+":"+minute+":"+second;
if(hour==0&&minute==0&&second==0)
{
document .getElementById ("currTime").style .display ="none";
}
else
setTimeout (Times,1000);
}
//當(dāng)窗體加載是調(diào)用。相當(dāng)于onload（）事件
 (function gettime()
  {
  $.ajax({
  contentType:"application/json",
  type: "POST",
  url: "WebService.asmx/Gettime",
  data: "{'id':'1'}",
  dataType: 'json',
  success: function(msq){
  document .getElementById ("currTime").innerHTML =msq.d ;
  }
  });
     setTimeout (Times,1000) ；
 })();
 </script>

多個倒計時>>>
