前台显示日期格式，则
function tsToTime(ts) {
var date = new Date(ts * 1000);//时间戳为10位需*1000，时间戳为13位的话不需乘1000
var Y = date.getFullYear() + ‘-‘;
var M = (date.getMonth()+1 < 10 ? ‘0‘+(date.getMonth()+1) : date.getMonth()+1) + ‘-‘;
var D = date.getDate() + ‘ ‘;
var h = date.getHours() + ‘:‘;
var m = date.getMinutes() + ‘:‘;
var s = date.getSeconds();
return Y+M+D+h+m+s;
}
tsToTime(1403793804);
console.log(tsToTime(1403793804));
var date = new Date(‘2018-11-28 02:47:30:097‘);
// 有三种方式获取
var time1 = date.getTime();
var time2 = date.valueOf();
var time3 = Date.parse(date);
console.log(time1);
console.log(time2);
console.log(time3);
