javascript - JS中有类似PHP date()方法吗?

如题,想实现功能。
传入时间戳“1400000000”,返回格式:2015-01-01

PHP实现:date("Y-m-d H:i:s","1400000000");
javascript实现呢??

随便实现了一下,写的比较糙,但是可以实现

function getFormatDate(split,timeInMs){
  var curr=new Date();
  curr.setTime(timeInMs);
  var year=curr.getFullYear();
  var month=curr.getMonth()+1;
  var date=curr.getDate();
  
  var hours=curr.getHours();
  var minutes=curr.getMinutes();
  var seconds=curr.getSeconds();
  
  var formatDateStr=year+split[0]+month+split[0]+date+" "+hours+split[1]+minutes+split[1]+seconds;
  return formatDateStr;
}

var res=getFormatDate(["-",":"],1433456000345); //这里要输入13位数
console.log(res); // 2015-6-5 6:13:20

自己实现的话可以看以上几位的,俺贴个插件。

兼容大部分PHP里面date函数的实现:

function date () {
    if (arguments.length == 0) {
        throw "date() expects at least 1 parameter, 0 given";
    }

    var format = arguments[0];
    var time = arguments.length > 1 ? new Date(arguments[1] * 1000) : new Date();

    var padding = function (str, length) {
        return "0000".substr(0, length - str.toString().length) + str;
    }

    return format.replace(/[a-z]/ig, function (c){
        var dayOfYear = function (time) {
            return (time.getTime() - (new Date(time.getFullYear(), 0, 1)).getTime()) / 86400000 >> 0;
        }

        var daysOfMonth = function (time) {
            var year = time.getFullYear();
            var month = time.getMonth();
            return ((new Date(year, month + 1, 1)).getTime() - (new Date(year, month, 1)).getTime()) / 86400000 >> 0;
        }

        var sign = function (num) {
            return num >= 0 ? "+" : "-";
        }

        switch (c) {
            case "d":
                return padding(time.getDate());
            case "D":
                return ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"][time.getDay()];

// 对Date的扩展,将 Date 转化为指定格式的String
// 月(M)、日(d)、小时(h)、分(m)、秒(s)、季度(q) 可以用 1-2 个占位符,
// 年(y)可以用 1-4 个占位符,毫秒(S)只能用 1 个占位符(是 1-3 位的数字)
function formatDate(date, fmt){ //author: meizz
    fmt = fmt || 'yyyy-MM-dd hh:mm:ss';
    var o = {
        "M+" : date.getMonth()+1,                 //月份
        "d+" : date.getDate(),                    //日
        "h+" : date.getHours(),                   //小时
        "m+" : date.getMinutes(),                 //分
        "s+" : date.getSeconds(),                 //秒
        "q+" : Math.floor((date.getMonth()+3)/3), //季度
        "S"  : date.getMilliseconds()             //毫秒
    };
    if(/(y+)/.test(fmt))
        fmt=fmt.replace(RegExp.$1, (date.getFullYear()+"").substr(4 - RegExp.$1.length));
    for(var k in o)
        if(new RegExp("("+ k +")").test(fmt))
            fmt = fmt.replace(RegExp.$1, (RegExp.$1.length==1) ? (o[k]) : (("00"+ o[k]).substr((""+ o[k]).length)));
    return fmt;
}

不用谢我,我也是从其他地方抄的

var unixTimestamp = new Date(1446027232 * 1000);
commonTime = unixTimestamp.toLocaleString();

希望这个也能帮到你一点。

有,不过不太好用。
另附其他语言版本

Java    time
JavaScript    Math.round(new Date().getTime()/1000)
getTime()返回数值的单位是毫秒
Microsoft .NET / C#    epoch = (DateTime.Now.ToUniversalTime().Ticks - 621355968000000000) / 10000000
MySQL    SELECT unix_timestamp(now())
Perl    time
PHP    time()
PostgreSQL    SELECT extract(epoch FROM now())
Python    先 import time 然后 time.time()
Ruby    获取Unix时间戳:Time.now 或 Time.new
显示Unix时间戳:Time.now.to_i
SQL Server    SELECT DATEDIFF(s, '1970-01-01 00:00:00', GETUTCDATE())
Unix / Linux    date +%s
VBScript / ASP    DateDiff("s", "01/01/1970 00:00:00", Now())
其他操作系统
(如果Perl被安装在系统中)    命令行状态:perl -e "print time"

建议使用momentjs,出bug的机会小;不过有时间可以研究楼上自己写的扩展。

楼上代码都不错,这里也有一个,大同小异.

function formatDate(now)   {     
              var   year=now.getYear();     
              var   month=now.getMonth()+1;     
              var   date=now.getDate();     
              var   hour=now.getHours();     
              var   minute=now.getMinutes();     
              var   second=now.getSeconds();     
              return   year+"-"+month+"-"+date+"   "+hour+":"+minute+":"+second;    
  } 

可以试试这个函数。
改下这个就行。
return year+"-"+month+"-"+date+" "+hour+":"+minute+":"+second;
