js时间戳与日期格式的相互转换

 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         var Y = date.getFullYear() + \'-\';
 4         var M = (date.getMonth()+1 < 10 ? \'0\'+(date.getMonth()+1) : date.getMonth()+1) + \'-\';
 5         var D = date.getDate() + \' \';
 6         var h = date.getHours() + \':\';
 7         var m = date.getMinutes() + \':\';
 8         var s = date.getSeconds();
 9         return Y+M+D+h+m+s;
10     }
11     timestampToTime(1403058804);
12     console.log(timestampToTime(1403058804));//2014-06-18 10:33:24

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
