你可以使用下面的代码:

var nowDate     = new Date();
var nowDay      = ((nowDate.getDate().toString().length) == 1) ? '0'+(nowDate.getDate()) : (nowDate.getDate());
var nowMonth    = ((nowDate.getMonth().toString().length) == 1) ? '0'+(nowDate.getMonth()+1) : (nowDate.getMonth()+1);
var nowYear     = nowDate.getFullYear();
var formatDate  = nowDay + "." + nowMonth + "." + nowYear;

你可以在这里找到一个工作演示

我只是想分享一个我用皮埃尔的想法做的时间戳原型。没有足够的点来评论:(

// US common date timestamp
Date.prototype.timestamp = function() {
  var yyyy = this.getFullYear().toString();
  var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based
  var dd  = this.getDate().toString();
  var h = this.getHours().toString();
  var m = this.getMinutes().toString();
  var s = this.getSeconds().toString();

  return (mm[1]?mm:"0"+mm[0]) + "/" + (dd[1]?dd:"0"+dd[0]) + "/" + yyyy + " - " + ((h > 12) ? h-12 : h) + ":" + m + ":" + s;
};

d = new Date();

var timestamp = d.timestamp();
// 10/12/2013 - 2:04:19

我知道我迟到了，但这就是你所需要的

var date = (new Date()).toISOString().split('T')[0];

toISOString()使用javascript的内置函数。

cd = (new Date()).toISOString().split('T')[0]; console.log (cd); 警报(cd);

var d = new Date();
var month = d.getMonth() + 1;
var day = d.getDate();
var year = d.getYear();
var today = (day<10?'0':'')+ day + '/' +(month<10?'0':'')+ month + '/' + year;
alert(today);

因为问题被标记为jQuery:

如果你也在使用jQuery UI，你可以使用$.datepicker.formatDate():

$.datepicker.formatDate('yy/mm/dd', new Date());

请看这个演示。

这是我只用jQuery得出的结果。只是把碎片拼在一起的问题。

        //Gather date information from local system
        var ThisMonth = new Date().getMonth() + 1;
        var ThisDay = new Date().getDate();
        var ThisYear = new Date().getFullYear();
        var ThisDate = ThisMonth.toString() + "/" + ThisDay.toString() + "/" + ThisYear.toString();

        //Gather time information from local system
        var ThisHour = new Date().getHours();
        var ThisMinute = new Date().getMinutes();
        var ThisTime = ThisHour.toString() + ":" + ThisMinute.toString();

        //Concatenate date and time for date-time stamp
        var ThisDateTime = ThisDate  + " " + ThisTime;
