1. 将时间戳转换成日期格式：
function timestampToTime(timestamp) {
var date = new Date(timestamp * 1000);//时间戳为10位需*1000，时间戳为13位的话不需乘1000
Y = date.getFullYear() + '-';
M = (date.getMonth()+1 < 10 ? '0'+(date.getMonth()+1) : date.getMonth()+1) + '-';
D = date.getDate() + ' ';
h = date.getHours() + ':';
m = date.getMinutes() + ':';
s = date.getSeconds();
return Y+M+D+h+m+s;
}
timestampToTime(1403058804);
console.log(timestampToTime(1403058804));//2014-06-18 10:33:24
注意：如果是Unix时间戳记得乘以1000。比如：
2. 将日期格式转换成时间戳：
var date = new Date('2014-04-23 18:55:49:123');
// 有三种方式获取
var time1 = date.getTime();
var time2 = date.valueOf();
var time3 = Date.parse(date);
console.log(time1);//1398250549123
console.log(time2);//1398250549123
console.log(time3);//1398250549000
