我试图写一个简单的库操作JavaScript日期对象。你可以试试这个。

var dateString = timeSolver.getString(date, "YYYYMMDD")

Libarary: https://github.com/sean1093/timeSolver

Moment.js可以成为你的朋友

var date = new Date();
var formattedDate = moment(date).format('YYYYMMDD');

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);

@o-o解对我没用。 我的解决方案如下:

Date.prototype.yyyymmdd = function() {
  var mm = this.getMonth() + 1; // getMonth() is zero-based
  var dd = this.getDate();
  var ret = [this.getFullYear(), (mm<10)?'0':'', mm, (dd<10)?'0':'', dd].join('');

  return ret; // padding
};

以下是对https://stackoverflow.com/users/318563/o-o的回答的一点改进

Date.prototype.ddmmyyyy = function(delimiter) {
    var yyyy = this.getFullYear().toString();
    var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based
    var dd  = this.getDate().toString();
    return (dd[1]?dd:"0"+dd[0]) + delimiter + (mm[1]?mm:"0"+mm[0]) + delimiter +yyyy  ; // padding
};

希望对大家有所帮助!

我希望这个函数会有用

function formatDate(dDate,sMode){       
        var today = dDate;
        var dd = today.getDate();
        var mm = today.getMonth()+1; //January is 0!
        var yyyy = today.getFullYear();
        if(dd<10) {
            dd = '0'+dd
        } 
        if(mm<10) {
            mm = '0'+mm
        } 
        if (sMode+""==""){
            sMode = "dd/mm/yyyy";
        }
        if (sMode == "yyyy-mm-dd"){
            return  yyyy + "-" + mm + "-" + dd + "";
        }
        if (sMode == "dd/mm/yyyy"){
            return  dd + "/" + mm + "/" + yyyy;
        }

    }
