这将给你当前日期字符串

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

你可以这样做:

    var now = new Date();
    dateFormat(now, "dddd, mmmm dS, yyyy, h:MM:ss TT");
     // Saturday, June 9th, 2007, 5:46:21 PM

或者类似的东西

    var dateObj = new Date();
    var month = dateObj.getUTCMonth();
    var day = dateObj.getUTCDate();
    var year = dateObj.getUTCFullYear();
    var newdate = month + "/" + day + "/" + year;
    alert(newdate);

当元素只有一个符号时，该对象设0:

function addZero(i) {
    if (i < 10) {
        i = "0" + i;
    }
    return i;
}

该对象设置实际的完整时间，小时和日期:

function getActualFullDate() {
    var d = new Date();
    var day = addZero(d.getDate());
    var month = addZero(d.getMonth()+1);
    var year = addZero(d.getFullYear());
    var h = addZero(d.getHours());
    var m = addZero(d.getMinutes());
    var s = addZero(d.getSeconds());
    return day + ". " + month + ". " + year + " (" + h + ":" + m + ")";
}

function getActualHour() {
    var d = new Date();
    var h = addZero(d.getHours());
    var m = addZero(d.getMinutes());
    var s = addZero(d.getSeconds());
    return h + ":" + m + ":" + s;
}

function getActualDate() {
    var d = new Date();
    var day = addZero(d.getDate());
    var month = addZero(d.getMonth()+1);
    var year = addZero(d.getFullYear());
    return day + ". " + month + ". " + year;
}

HTML:

<span id='full'>a</span>
<br>
<span id='hour'>b</span>
<br>    
<span id='date'>c</span>

JQUERY的观点:

$(document).ready(function(){
    $("#full").html(getActualFullDate());
    $("#hour").html(getActualHour());
    $("#date").html(getActualDate());
});

例子

function GetTodayDate() {
   var tdate = new Date();
   var dd = tdate.getDate(); //yields day
   var MM = tdate.getMonth(); //yields month
   var yyyy = tdate.getFullYear(); //yields year
   var currentDate= dd + "-" +( MM+1) + "-" + yyyy;

   return currentDate;
}

非常方便的功能使用，享受。你不需要任何javascript框架。它只是在简单的javascript工作。

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);

在JavaScript中，你可以使用date对象获取当前日期和时间;

var now = new Date();

这将获得本地客户端机器时间

如果你正在使用jQuery DatePicker，你可以应用它在任何文本框，像这样:

$( "#datepicker" ).datepicker({dateFormat:"yy/mm/dd"}).datepicker("setDate",new Date());
