转换layUI的数据表格中的日期格式方法

转换layUI的数据表格中的日期格式

前端jsp代码

 <table class=\"layui-table\" style=\"width:100%\" lay-data=\"{url:\'/why123/user/findUserAll?userType=0\', page:true, id:\'idTest\'}\" lay-filter=\"demo\">
 <thead>
 <tr>
  <th lay-data=\"{type:\'checkbox\', fixed: \'left\'}\"></th>
  <th lay-data=\"{field:\'userName\',align:\'center\'}\">用户名</th>
  <th lay-data=\"{field:\'gender\',align:\'center\',width:80}\">性别</th>
  <th lay-data=\"{field:\'mobile\',align:\'center\'}\">手机号码</th>
  <th lay-data=\"{field:\'email\',align:\'center\'}\">电子邮箱</th>
  <th lay-data=\"{field:\'userheat\',align:\'center\',width:100,sort:\'true\'}\">人气</th>
  <th lay-data=\"{field:\'regDate\',align:\'center\',templet:\'<div>{{ layui.laytpl.toDateString(d.regDate) }}</div>\'}\">注册时间</th>
  <th lay-data=\"{field:\'lastLogin\',align:\'center\',templet:\'<div>{{ layui.laytpl.toDateString(d.lastLogin) }}</div>\'}\">最后一次登录时间</th>
  <th lay-data=\"{fixed: \'right\', width:178, align:\'center\', toolbar: \'#barDemo\'}\">操作</th>
 </tr>
 </thead>
</table>

js代码：

layui.use(\'laytpl\', function(){
 var laytpl = layui.laytpl;
 //时间戳的处理
 layui.laytpl.toDateString = function(d, format){
 if(d==null||d==\'\'){
  return \"未登录\";
 }else{
 var date =new Date(d.time) 
 ,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;
 };
 });

注意：

1、需引入laytpl模块

2、后台返回json的String类型，否则如果数据为空，会出错，错误如下：
