商淘wstmart電商平臺的營銷模塊中的限時搶購功能是如何實現(xiàn)的呢？實現(xiàn)該功能的函數(shù)代碼段是什么的呢？接下來就由小編wstmart帶大家一起來看看吧。

商淘wstmart電商平臺的秒殺活動的倒計時是根據(jù)后臺設(shè)置好的時段與當(dāng)前時間來計算，然后通過定時器來執(zhí)行代碼形成倒計時效果。

在顯示倒計時的頁面調(diào)用WST.countDown函數(shù)。

代碼段：

WST.countDown = function(opts){
   var itvTime = (opts.countDownType==1)?100:1000;
   var f = {
      zero: function(n){
         var n = parseInt(n, 10);
         if(n > 0){
            if(n <= 9){
               n = "0" + n;   
            }
            return String(n);
         }else{
            return "0";    
         }
      },
      count: function(){
         if(opts.nowTime){
            var d = new Date();
            d.setTime(opts.nowTime.getTime()+itvTime);
            opts.nowTime = d;
            d = null;
         }else{
            opts.nowTime = new Date();
         }
         //現(xiàn)在將來秒差值
         var dur = 0;
         var pms = {
            msec: "0",
            sec: "0",
            mini: "0",
            hour: "0",
            day: "0"
         };
         var dur = Math.round((opts.endTime.getTime() - opts.nowTime.getTime()));
         if(dur >= 0){
            pms.msec = Math.floor(dur / 100 % 10);
            pms.sec = Math.floor((dur /1000 % 60)) > 0? f.zero(dur / 1000 % 60) : "00";
            pms.mini = Math.floor((dur / 60000)) > 0? f.zero(Math.floor((dur / 60000)) % 60) : "00";
            pms.hour = Math.floor((dur / 3600000)) > 0? f.zero(Math.floor((dur / 3600000)) % 24) : "00";
            pms.day = Math.floor((dur / 86400000)) > 0? f.zero(Math.floor(dur / 86400000)) : "00";
         }
         pms.last = dur;
         pms.nowTime = opts.nowTime;
         opts.callback(pms);
         if(pms.last<=0)clearInterval(itv);
      }
   };
   var itv = setInterval(f.count, itvTime);
   return itv;
};
