javascript - 将JavaScript日期格式设置为yyyy-mm-dd(Format JavaScript date as yyyy-mm-dd)

Question

I have a date with the format Sun May 11,2014 .

(我有一个日期为Sun May 11,2014 。)

How can I convert it to 2014-05-11 using JavaScript?

(如何使用JavaScript将其转换为2014-05-11 ？)

function taskDate(dateMilli) {
    var d = (new Date(dateMilli) + '').split(' ');
    d[2] = d[2] + ',';

    return [d[0], d[1], d[2], d[3]].join(' ');
}

var datemilli = Date.parse('Sun May 11,2014');
taskdate(datemilli);

The code above gives me the same date format, sun may 11,2014 .

(上面的代码为我提供了相同的日期格式，即sun may 11,2014 。)

How can I fix this?

You can do:

(你可以做：)

function formatDate(date) {
    var d = new Date(date),
        month = '' + (d.getMonth() + 1),
        day = '' + d.getDate(),
        year = d.getFullYear();

    if (month.length < 2) 
        month = '0' + month;
    if (day.length < 2) 
        day = '0' + day;

    return [year, month, day].join('-');
}
