前台往后台传值为时间戳

where.createstime = timeToStamp(data.field.createstime);

定义 layui.laytpl.toDateString 自己的方法 并使用 2  在定义

//时间戳的处理2 layui.laytpl.toDateString = function(d, format){
     var date = new Date(d || new Date())   ,ymd = [     this.digit(date.getFullYear(), 4)     ,this.digit(date.getMonth() + 1)     ,this.digit(date.getDate())   ]   ,hms = [     this.digit(date.getHours())     ,this.digit(date.getMinutes())     ,this.digit(date.getSeconds())   ];   format = format || 'yyyy-MM-dd HH:mm:ss';   return format.replace(/yyyy/g, ymd[0])   .replace(/MM/g, ymd[1])   .replace(/dd/g, ymd[2])   .replace(/HH/g, hms[0])   .replace(/mm/g, hms[1])   .replace(/ss/g, hms[2]); }; //数字前置补零 layui.laytpl.digit = function(num, length, end){
     var str = '';   num = String(num);   length = length || 2;   for(var i = num.length; i < length; i++){
       str += '0';   }   return num < Math.pow(10, length) ? str + (num|0) : num; }; 在列模板中调用时间戳的处理方法

table.render({ //其它参数在此省略   elem: '#demo'   ,cols: [[     {field: 'createTime', title: '创建时间', templet: '
     
      {
    { layui.laytpl.toDateString(d.time) }}
     
'}   ]] });
