Fungsi Tanggal Javascript tidak berfungsi

Saya mencoba menampilkan teks '09 Okt 2012'. Sebaliknya itu tidak menjalankan fungsinya dan menampilkan banyak teks tanggal yang tidak perlu. Adakah yang tahu apa yang saya lakukan salah?

Anda dapat bermain dengan jsfiddle saya... http://jsfiddle.net/UP3fd/

Ini kodenya...

var myDate = new Date();

convertDate(myDate);

myDate.setFullYear(2012, 9, 9);

document.write(myDate);

function convertDate(d) {
    var day = d.getDate();
    if (day < 10) {
        day = "0" + day;
    }
    var year = d.getFullYear();
    var month = d.getMonth();
    var months=["Jan","Feb","Mar","Apr","May","June","July","Aug","Sep","Oct"," Nov","Dec"];
    var currentMonth = months[month];
    return (currentMonth + " " + day + ", " + year);
}

javascript html date

Anda memanggil fungsi Anda sebelum menetapkan tanggal, dan Anda tidak menyimpan/mengeluarkan nilai kembalian di mana pun.

var myDate = new Date();

myDate.setFullYear(2012, 9, 9);

document.write( convertDate(myDate) );

function convertDate(d) {
    var day = d.getDate();
    if (day < 10) {
        day = "0" + day;
    }
    var year = d.getFullYear();
    var month = d.getMonth();
    var months=["Jan","Feb","Mar","Apr","May","June","July","Aug","Sep","Oct"," Nov","Dec"];
    var currentMonth = months[month];
    return (currentMonth + " " + day + ", " + year);
}

Ini adalah kode yang benar:

var myDate = new Date();
myDate.setFullYear(2012, 9, 9);
myDate = convertDate(myDate);
document.write(myDate);

Ini kode yang diperbaiki, ini akan mengembalikan apa yang Anda harapkan.

var myDate = new Date();

myDate.setFullYear(2012, 9, 9);

var newDate = convertDate(myDate);

document.write(newDate);

function convertDate(d) {
    var day = d.getDate();
    if (day < 10) {
        day = "0" + day;
    }
    var year = d.getFullYear();
    var month = d.getMonth();
    var months=["Jan","Feb","Mar","Apr","May","June","July","Aug","Sep","Oct"," Nov","Dec"];
    var currentMonth = months[month];
    return (currentMonth + " " + day + ", " + year);
