Convert timestamp to date format

var date = new Date(时间戳);获取一个时间对象。
下面是获取时间日期的方法
下面是获取时间日期的方法。
date.getFullYear();//获取完整的年份(4位,1970)
date.getMonth();//获取月份(0-11,0代表1月,用的时候记得加上1)
date.getDate();//获取日(1-31)
date.getTime();//获取时间(从1970.1.1开始的毫秒数)
date.getHours();//获取小时数(0-23)
date.getMinutes();//获取分钟数(0-59)
date.getSeconds();//获取秒数(0-59)

For example, I need a format like 2015-8-24_8-24-30

function formatDate(datetime) {
  var year = datetime.getFullYear(),
  month = (datetime.getMonth() + 1 < 10) ? &#39;0&#39; + (datetime.getMonth() + 1):datetime.getMonth() + 1,
  day = datetime.getDate() < 10 ? &#39;0&#39; + datetime.getDate() : datetime.getDate(),
  hour = datetime.getHours() < 10 ? &#39;0&#39; + datetime.getHours() : datetime.getHours(),
  min = datetime.getMinutes() < 10 ? &#39;0&#39; + datetime.getMinutes() : datetime.getMinutes(),
  sec = datetime.getSeconds() < 10 ? &#39;0&#39; + datetime.getSeconds() : datetime.getSeconds();
  return year + &#39;-&#39; + month + &#39;-&#39; + day + &#39;_&#39; + hour + &#39;-&#39; + min + &#39;-&#39; + sec;
}

Here datatime is a Date object, formatted datetime = new Date(time); time is a timestamp.

Convert date format to timestamp

var strtime = '2014-04-23 18:55:49:123';
var date = new Date(strtime); 
//传入一个时间格式，如果不传入就是获取现在的时间了，这样做不兼容火狐。
// 可以这样做
var arr = strtime.replace(/ |:/g, '-').split('-');
date = new Date(Date.UTC(arr[1], arr[2], arr[3], arr[4], arr[5]));

//三种方式获取：
time1 = date.getTime();
time2 = date.valueOf();
time3 = Date.parse(date);

//三种获取的区别：
第一、第二种：会精确到毫秒
第三种：只能精确到秒，毫秒将用0来代替
比如上面代码输出的结果(一眼就能看出区别)：
  1398250549123
  1398250549123
  1398250549000

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
