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());

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。

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);

试试这个…

var d = new Date();
alert(d.getFullYear()+'/'+(d.getMonth()+1)+'/'+d.getDate());

getMonth()返回月份0到11，因此我们希望添加1来表示准确的月份

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;

//convert month to 2 digits<p>
var twoDigitMonth = ((fullDate.getMonth().length+1) === 1)? (fullDate.getMonth()+1) : '0' + (fullDate.getMonth()+1);

var currentDate =  fullDate.getFullYear()+ "/" + twoDigitMonth + "/" + fullDate.getDate();
console.log(currentDate);<br>
