时间戳转换作用域问题

方法一：

var ss = "";//在外面声明

function time(){
var date = new Date(parseInt(datas.createtime));//时间戳必须为整形，int
var y = date.getFullYear();
var m = date.getMonth() + 1;
m = m < 10 ? ('0' + m) : m;
var d = date.getDate();
d = d < 10 ? ('0' + d) : d;
var h = date.getHours();
h = h < 10 ? ('0' + h) : h;
var minute = date.getMinutes();
var second = date.getSeconds();
minute = minute < 10 ? ('0' + minute) : minute;
second = second < 10 ? ('0' + second) : second;
ss = y + '-' + m + '-' + d + ' ' + h + ':' + minute
+ ':' + second;
console.log(ss, 11)
}

time(datas.createtime);//传参调用函数

$(".createtimes").text(ss);

方法二：

function time(){

var ss = "";
var date = new Date(parseInt(datas.createtime));//时间戳必须为整形，int
var y = date.getFullYear();
var m = date.getMonth() + 1;
m = m < 10 ? ('0' + m) : m;
var d = date.getDate();
d = d < 10 ? ('0' + d) : d;
var h = date.getHours();
h = h < 10 ? ('0' + h) : h;
var minute = date.getMinutes();
var second = date.getSeconds();
minute = minute < 10 ? ('0' + minute) : minute;
second = second < 10 ? ('0' + second) : second;
ss = y + '-' + m + '-' + d + ' ' + h + ':' + minute
+ ':' + second;
return ss ;
}

$(".createtimes").text(time);
