var dateDisplay = new Date( 2016-11-09 05:27:00 UTC );
dateDisplay = dateDisplay.toString()
var arr = (dateDisplay.split(' '))
var date_String =  arr[0]+','+arr[1]+' '+arr[2]+' '+arr[3]+','+arr[4]

这将显示像Wed,Nov 09 2016,10:57:00这样的字符串

我不喜欢增加原型。另一种选择是:

var rightNow = new Date(); var res = rightNow.toISOString().slice(0,10).replace(/-/g，""); <！——下一行仅用于代码段输出——> document.body.innerHTML += res;

<pre>Date.prototype.getFromFormat = function(format) {
    var yyyy = this.getFullYear().toString();
    format = format.replace(/yyyy/g, yyyy)
    var mm = (this.getMonth()+1).toString(); 
    format = format.replace(/mm/g, (mm[1]?mm:"0"+mm[0]));
    var dd  = this.getDate().toString();
    format = format.replace(/dd/g, (dd[1]?dd:"0"+dd[0]));
    var hh = this.getHours().toString();
    format = format.replace(/hh/g, (hh[1]?hh:"0"+hh[0]));
    var ii = this.getMinutes().toString();
    format = format.replace(/ii/g, (ii[1]?ii:"0"+ii[0]));
    var ss  = this.getSeconds().toString();
    format = format.replace(/ss/g, (ss[1]?ss:"0"+ss[0]));
    var ampm = (hh >= 12) ? "PM" : "AM";
    format = format.replace(/ampm/g, (ampm[1]?ampm:"0"+ampm[0]));
    return format;
};
var time_var = $('#899_TIME');
var myVar = setInterval(myTimer, 1000);
function myTimer() {
    var d = new Date(); 
    var date = d.getFromFormat('dd-mm-yyyy hh:ii:ss:ampm');
    time_var.text(date);

} </pre>

use the code and get the output like **26-07-2017 12:29:34:PM**

除了o-o的答案之外，我还建议将逻辑操作与返回值分离，并将它们作为三元放入变量中。

另外，使用concat()来确保变量的安全连接

Date.prototype.yyyymmdd = function() { var yyyy = this.getFullYear(); var mm = this.getMonth() < 9 ? "0" + (this.getMonth() + 1) : (this.getMonth() + 1); // getMonth() is zero-based var dd = this.getDate() < 10 ? "0" + this.getDate() : this.getDate(); return "".concat(yyyy).concat(mm).concat(dd); }; Date.prototype.yyyymmddhhmm = function() { var yyyymmdd = this.yyyymmdd(); var hh = this.getHours() < 10 ? "0" + this.getHours() : this.getHours(); var min = this.getMinutes() < 10 ? "0" + this.getMinutes() : this.getMinutes(); return "".concat(yyyymmdd).concat(hh).concat(min); }; Date.prototype.yyyymmddhhmmss = function() { var yyyymmddhhmm = this.yyyymmddhhmm(); var ss = this.getSeconds() < 10 ? "0" + this.getSeconds() : this.getSeconds(); return "".concat(yyyymmddhhmm).concat(ss); }; var d = new Date(); document.getElementById("a").innerHTML = d.yyyymmdd(); document.getElementById("b").innerHTML = d.yyyymmddhhmm(); document.getElementById("c").innerHTML = d.yyyymmddhhmmss(); <div> yyyymmdd: <span id="a"></span> </div> <div> yyyymmddhhmm: <span id="b"></span> </div> <div> yyyymmddhhmmss: <span id="c"></span> </div>

这篇文章帮助我写了这个助手，所以我分享它以防有人 正在寻找这个解决方案，它支持yyyy, mm, dd的所有变化

Date.prototype.formattedDate = function (pattern) {
    formattedDate = pattern.replace('yyyy', this.getFullYear().toString());
    var mm = (this.getMonth() + 1).toString(); // getMonth() is zero-based
    mm = mm.length > 1 ? mm : '0' + mm;
    formattedDate = formattedDate.replace('mm', mm);
    var dd = this.getDate().toString();
    dd = dd.length > 1 ? dd : '0' + dd;
    formattedDate = formattedDate.replace('dd', dd);
    return formattedDate;
};

d = new Date();
pattern = 'yyyymmdd';  // 20150813
d.formattedDate(pattern);

pattern = 'yyyy-mm-dd';
d.formattedDate(pattern); // 2015-08-13

要获得本地日期，YYYYMMDD格式，我使用:

var todayDate = (new Date()).toLocaleString('en-GB').slice(0,10).split("\/").reverse().join("");
