get Javascript date formatted as 2011-04-01

问题:

I've seen this: how to get formatted date time like 2009-05-29 21:55:57 using javascript?

but I do need the 0's before a single digit date(I need 2011-04-01, not 2011-4-1)

I don't like to add another unnecessary plugin for this one so if there's a builtin function or SIMPLE function in js/jquery that could do this, I'm good. I do hope it will not result to a 10 line function just to check if the month was singular and then add a zero to it.

Basically, I am using the AnyTime js (http://www.ama3.com/anytime/) plugin but it throws an error if my starting date was not in the form "yyyy-mm-dd". My starting default value is "now" so I am trying to convert a new Date() to that format. Any help?

NOTE please don't give links of plugins as i was hoping for a REALLY simple solution. i find that using a plugin just to fix a plugin isn't actually very clean.

   function getFormattedDate() {
        var date = new Date();
        var str = date.getFullYear() + "-" + getFormattedPartTime(date.getMonth()) + "-" + getFormattedPartTime(date.getDate()) + " " +  getFormattedPartTime(date.getHours()) + ":" + getFormattedPartTime(date.getMinutes()) + ":" + getFormattedPartTime(date.getSeconds());

        return str;
    }

    function getFormattedPartTime(partTime){
        if (partTime<10)
           return "0"+partTime;
        return partTime;
    }

vvk's effort is pretty much on the money, here's a minor modification of the same thing:

var getDate = (function() {
  function addZ(n) {
    return n<10? '0'+n : ''+n;
  }
  return function() {
    var d = new Date();
    return d.getFullYear()+'-'+addZ(d.getMonth()+1)+'-'+addZ(d.getDate());
  }
}());

The Any+Time(TM) library includes an object named AnyTime.Converter specifically for parsing and formatting dates, so you could have done this:

(new AnyTime.Converter({format:"%Y-%M-%d"})).format(new Date());

However, the library also defaults to the current date/time if the field is empty or does not match the format specifier, so you really could just leave the field empty when you display the form!
