Tanggal JavaScript memiliki beberapa metode yang memungkinkan Anda mengekstrak bagian-bagiannya:
getFullYear()
- Mengembalikan tahun 4-digit
getMonth()
- Mengembalikan bilangan bulat berbasis nol (0-11) yang mewakili bulan dalam setahun.
getDate()
- Mengembalikan hari dalam sebulan (1-31).
getDay()
- Mengembalikan hari dalam seminggu (0-6). 0 adalah Minggu, 6 adalah Sabtu.
getHours()
- Mengembalikan jam dalam sehari (0-23).
getMinutes()
- Mengembalikan menit (0-59).
getSeconds()
- Mengembalikan detik (0-59).
getMilliseconds()
- Mengembalikan milidetik (0-999).
getTimezoneOffset()
- Mengembalikan jumlah menit antara waktu lokal mesin dan UTC.
Tidak ada metode bawaan yang memungkinkan Anda mendapatkan string yang dilokalkan seperti "Friday", "February", atau "PM". Anda harus mengkodekannya sendiri. Untuk mendapatkan string yang Anda inginkan, Anda setidaknya perlu menyimpan representasi string hari dan bulan:
var months = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];
var days = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
Kemudian, gabungkan menggunakan metode di atas:
var months = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];
var days = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
var d = new Date();
var day = days[d.getDay()];
var hr = d.getHours();
var min = d.getMinutes();
if (min < 10) {
min = "0" + min;
}
var ampm = "am";
if( hr > 12 ) {
hr -= 12;
ampm = "pm";
}
var date = d.getDate();
var month = months[d.getMonth()];
var year = d.getFullYear();
var x = document.getElementById("time");
x.innerHTML = day + " " + hr + ":" + min + ampm + " " + date + " " + month + " " + year;
<span id="time"></span>
Saya memiliki fungsi format tanggal yang ingin saya sertakan di perpustakaan standar saya. Dibutuhkan parameter string format yang mendefinisikan keluaran yang diinginkan. String format secara longgar didasarkan pada string format Tanggal dan Waktu kustom .Net . Untuk format yang Anda tentukan format string berikut akan bekerja: "dddd h:mmtt d MMM yyyy"
.
var d = new Date();
var x = document.getElementById("time");
x.innerHTML = formatDate(d, "dddd h:mmtt d MMM yyyy");
