时间格式转换/时间戳的转换

mengzekun 2021-12-10 原文

1、Thu Mar 07 2019 12:00:00 GMT+0800 (中国标准时间) 转换为 2019-03-07 12:00:00

const d = new Date(Thu Mar 07 2019 12:00:00 GMT+0800 (中国标准时间))
const resDate = d.getFullYear() + \'-\' + this.p((d.getMonth() + 1)) + \'-\' + this.p(d.getDate())
const resTime = this.p(d.getHours()) + \':\' + this.p(d.getMinutes()) + \':\' + this.p(d.getSeconds())

p为不够10添加0的函数

p(s) {
      return s < 10 ? \'0\' + s : s
    },

2、2019-03-07 12:00:00转换为 Thu Mar 07 2019 12:00:00 GMT+0800 (中国标准时间)

　1、　parserDate(date) {
      var t = Date.parse(date)
      if (!isNaN(t)) {
        return new Date(Date.parse(date.replace(/-/g, \'/\')))
      }
    },
　2、

　　　　 var a=\’2020-01-01\’;

a = a.replace(/-/g,\’/\’)

　var dateA = (new Date(a)).getTime()

3、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
        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;
    }
    timestampToTime(1403058804);
    console.log(timestampToTime(1403058804));//2014-06-18 10:33:24

4、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
