//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>
//2011/05/19

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

关闭jQuery插件页面。所以手动:

function strpad00(s)
{
    s = s + '';
    if (s.length === 1) s = '0'+s;
    return s;
}

var now = new Date();
var currentDate = now.getFullYear()+ "/" + strpad00(now.getMonth()+1) + "/" + strpad00(now.getDate());
console.log(currentDate );

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。

//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>
//2011/05/19
