JavaScript Format date with zeroes

Question

I am using a function to log some stuff that happens in the background and this is the code I use to get the date and hour, etc.

function fStartLog() {

    var oDate = new Date();
    var sDate = oDate.getDate() +"/"+ oDate.getMonth() +"/"+ oDate.getFullYear() +" - "+ oDate.getHours() +":"+ oDate.getMinutes() +":"+ oDate.getSeconds();

    console.log("["+ sDate +"] mysite.com > Loading DONE!");

}

My question is, how can I get the date in a format with zeroes. Example:

[WRONG] 5/7/2013 - 22:5:9
[GOOD] 05/07/2013 - 22:05:09

See stackoverflow.com/questions/2686855/…

You can also use moment.js. It's extemely powerful.

I believe something like this would give you what you need.

moment().format('L[ - ]hh:mm:ss');

Should I download the "mini" version? Will that work with your example?

From my understanding, the only difference is that the the source is minified (en.wikipedia.org/wiki/Minification_(programming)), but the syntax should be the same, so: yes :)

I like to use a simple helper function: pad=function(n){return n<10?"0"+n:n;};

Then you can do sDate = pad(oDate.getDate())+"/"+.....

It works perfectly... the only thing is that the sDate string now is pretty large. But it works, thanks.

Basically, if you convert the numbers returned from the date methods to a string and check the length, you can add a zero...

function fStartLog() {

    var oDate = new Date();

    var dd = oDate.getDate().toString();
    if (dd.length == 1) {
        dd = "0" + dd;
    }

    var mm = oDate.getMonth().toString();
    if (mm.length == 1) {
        mm = "0" + mm;
    }

    var sDate = dd +"/"+ mm +"/"+ oDate.getFullYear() +" - "+ oDate.getHours() +":"+ oDate.getMinutes() +":"+ oDate.getSeconds();

    console.log("["+ sDate +"] mysite.com > Loading DONE!");
}

Cheers!

That is a good answer but isn't it a bit redundant to make a function per each value? (minute, hour, day, etc) For instance, take a look at the answer of Kolink... it works perfectly only with a function. Thanks!
