转换layUI的数据表格中的日期格式
前端jsp代码
<table 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：
