JavaScript 日期与时间戳互转

 1 function timestampToTime(timestamp) {
 2         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
 3         Y = date.getFullYear() + ‘-‘;
 4         M = (date.getMonth() + 1 < 10 ? ‘0‘ + (date.getMonth() + 1) : date.getMonth() + 1) + ‘-‘;
 5         D = date.getDate() + ‘ ‘;
 6         h = date.getHours() + ‘:‘;
 7         m = date.getMinutes() + ‘:‘;
 8         s = date.getSeconds();
 9         return Y + M + D + h + m + s;
10     }

1 var date = new Date(‘2014-04-23 18:55:49:123‘);
2     // 有三种方式获取
3     var time1 = date.getTime();
4     var time2 = date.valueOf();
5     var time3 = Date.parse(date);
6     console.log(time1);//1398250549123
7     console.log(time2);//1398250549123
8     console.log(time3);//1398250549000
