一.日期转时间戳
1. 获取当前时间的时间戳
var date1 = new Date()
var timestamp1 = Date.parse(date1);
console.log(timestamp1);
//1511244766000
2. 获取某个时间格式的时间戳
var date2 = '2016-11-21 09:00:00'
var timestamp2 = Date.parse(new Date(date2));
console.log(timestamp2);
//1479690000000
二.时间戳转日期
1.时间戳转各种格式日期
var timestamp3 = 1479690000000;
var newDate = new Date();
var a = newDate.setTime(timestamp3)
console.log(a);//1479690000000
console.log(newDate.toDateString());
// Mon Nov 21 2016
console.log(newDate.toTimeString());
// 09:00:00 GMT+0800 (CST)
console.log(newDate.toJSON());
// 2016-11-21T01:00:00.000Z
console.log(newDate.toISOString());
// 2016-11-21T01:00:00.000Z
console.log(newDate.toGMTString());
// Mon, 21 Nov 2016 01:00:00 GMT
console.log(newDate.toLocaleDateString());
// 2016/11/21
console.log(newDate.toLocaleString());
// 2016/11/21 上午9:00:00
console.log(newDate.toLocaleTimeString());
// 上午9:00:00
console.log(newDate.toString());
// Mon Nov 21 2016 09:00:00 GMT+0800 (CST)
console.log(newDate.toTimeString());
// 09:00:00 GMT+0800 (CST)
2.通用函数
Date.prototype.format = function(format) {
var date = {
"M+": this.getMonth() + 1,
"d+": this.getDate(),
"h+": this.getHours(),
"m+": this.getMinutes(),
"s+": this.getSeconds(),
"q+": Math.floor((this.getMonth() + 3) / 3),
"S+": this.getMilliseconds()
};
if (/(y+)/i.test(format)) {
format = format.replace(RegExp.$1, (this.getFullYear() + '').substr(4 - RegExp.$1.length));
}
for (var k in date) {
if (new RegExp("(" + k + ")").test(format)) {
format = format.replace(RegExp.$1, RegExp.$1.length == 1
? date[k] : ("00" + date[k]).substr(("" + date[k]).length));
}
}
return format;
}
var timestamp3 = 1479690000000;
var newDate = new Date();
newDate.setTime(timestamp3)
console.log(newDate.format('yyyy-MM-dd h:m:s'));
//2016-11-21 9:0:0
3.输出固定日期的函数
var abc = 1511191725638
function time(timeStamp) {
var date = new Date();
date.setTime(timeStamp);
var y = date.getFullYear()
//第一个月份是从0算起的，所以月份要加1
var m = date.getMonth() + 1;
m = m < 10 ? ('0' + m) : m;
var d = date.getDate();
d = d < 10 ? ('0' + d) : d;
var h = date.getHours();
h = h < 10 ? ('0' + h) : h;
var min = date.getMinutes();
var sec = date.getSeconds();
min = min< 10 ? ('0' + min) : min;
sec = sec < 10 ? ('0' + sec) : sec;
return y + '-' + m + '-' + d+' '+h+':'+min+':'+sec;
};
console.log(time(abc)); //2017-11-20 23:28:45
