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

这里很多答案都使用toisostring函数。这个函数在输出之前将时间转换为zulu时间，这可能会导致问题。

function datestring(time) {
    return new Date(time.getTime() - time.getTimezoneOffset()*60000).toISOString().slice(0,10).replace(/-/g,"")
}

mydate = new Date("2018-05-03")
console.log(datestring(mydate))

datestring函数修复了时区问题，或者更好的是，你可以通过使用zulu时间来避免整个问题:

mydate = new Date("2018-05-03Z")
// mydate = new Date(Date.UTC(2018,5,3))
console.log(mydate.toISOString().slice(0,10).replace(/-/g,""))

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>

纯JS (ES5)解决方案，没有任何可能的日期跳转问题，由date . toisostring()打印UTC:

var now = new Date();
var todayUTC = new Date(Date.UTC(now.getFullYear(), now.getMonth(), now.getDate()));
return todayUTC.toISOString().slice(0, 10).replace(/-/g, '');

这是为了回应@weberste对@Pierre Guilbert的回答的评论。

很好，很简单:

    var date = new Date();
    var yyyy = date.getFullYear();
    var mm = date.getMonth() + 1; // getMonth() is zero-based
    if (mm < 10) mm='0'+mm;
    var dd = date.getDate();
    if (dd < 10) dd='0'+dd;
    /*date.yyyymmdd();*/

    console.log('test - '+yyyy+'-'+mm+'-'+dd);

new Date('Jun 5 2016').
  toLocaleString('en-us', {year: 'numeric', month: '2-digit', day: '2-digit'}).
  replace(/(\d+)\/(\d+)\/(\d+)/, '$3-$1-$2');

// => '2016-06-05'
