jquery


$(function(){
  var abj = $("#shop_rec"),
    timeObj = abj.find(&#39;.time&#39;);
  var starttime = timeObj.data(&#39;starttime&#39;);

  // 定时器函数
  function actionDo(){
    return setInterval(function(){
      timeObj.each(function(index, el) {
        var t = $(this),
          surplusTime = t.data(&#39;endtime&#39;) -starttime;
        if (surplusTime <= 0) {
          t.html("活动已经开始");
        } else{
          var year = surplusTime/(24*60*60*365),
            showYear = parseInt(year),
            month = (year-showYear)*12,
            showMonth = parseInt(month),
            day = (month-showMonth)*30,
            showDay = parseInt(day),
            hour = (day-showDay)*24,
            showHour = parseInt(hour),
            minute = (hour-showHour)*60,
            showMinute = parseInt(minute),
            seconds = (minute-showMinute)*60,
            showSeconds = parseInt(seconds);
          t.html("");
          if (showYear>0) {
            t.append("<span>"+showYear+"年</span>")
          };
          if (showMonth>0) {
            t.append("<span>"+showMonth+"月</span>")
          };
          if (showDay>0) {
            t.append("<span>"+showDay+"天</span>")
          };
          if (showHour>=0) {
            t.append("<span>"+showHour+"小时</span>")
          };
          if (showMinute>=0) {
            t.append("<span>"+showMinute+"分钟</span>")
          };
          if (showSeconds>=0) {
            t.append("<span>"+showSeconds+"秒</span>")
          };
        };
      });
      starttime++;
    },1000); // 设定执行或延时时间
  };
  // 执行它
  actionDo();
});

不是特别优秀,但是小的应用完全没有问题。
