小程序里面做倒计时

第一步,建立util.wxs

第二步:util.wxs里面的内容

module.exports = {
    formatTimeLeft: function(timeleft){ 
        var day = 0;
        var hour = 0;
        var min = 0;
        var second = 0;
        //计算天
        day =  parseInt(timeleft / (24 * 60 * 60));
        hour = parseInt((timeleft - day * (24 * 60 * 60)) / (60 * 60));
        min =  parseInt((timeleft - day * (24 * 60 * 60) - hour * (60 * 60))/ 60  );
        second = parseInt(timeleft - day * (24 * 60 * 60) - hour * (60 * 60) - min * 60);
        if(day > 0){
            return day+"天"+hour+"时"+min+"分";
        }else{
           return  hour+"时"+min+"分"+second+"秒";
        }
    },
    dateteap: function (timestamp) {
      var date = getDate(timestamp)
      var year = date.getFullYear()
      var month = date.getMonth() + 1
      var day = date.getDate()

      var hour = date.getHours()
      var minute = date.getMinutes()
      var second = date.getSeconds()
      return year+\'-\'+month+\'-\'+day
    },
    getday:function(times) {
        return Math.round(times / 86400)
    },
    newdate:function(timestamp){
      var date = getDate(timestamp)
      var year = date.getFullYear()
      var month = date.getMonth() + 1
      var day = date.getDate()

      var hour = date.getHours()
      var minute = date.getMinutes()
      var second = date.getSeconds()
      return month+\'月\'+day+"日"
    }    
}

第三步,在要渲染的文件中引入wxs模块

第四步:页面显示
