Mengambil nilai jarak antara dua tanggal (javascript)

by Jawaad · Published 21 January 2009 · Updated 21 January 2009

Menampilkan jarak jumlah hari diantara 2 tanggal.
contoh:
tanggal mulai: 2009-01-29
tanggal akhir: 2009-02-03
hasil jarak tanggal dalam jumlah hari = 5

Fungsi scriptnya sbb, simpan dengan nama file datediff.js:

var DayName=["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"];

var intervalObject=new Object();
intervalObject["yyyy"]={units:1000*60*60*24*365,measure:"year"};
intervalObject["m"]={units:1000*60*60*24*30,measure:"month"};
intervalObject["d"]={units:1000*60*60*24,measure:"day"};
intervalObject["Q"]={units:intervalObject["m"].units*3,measure:"quarter"};
intervalObject["H"]={units:oneMinute*60,measure:"hour"};
intervalObject["N"]={units:oneMinute,measure:"minute"};
intervalObject["S"]={units:1000,measure:"second"};

Penggunaan:

<html>
<head>
<script type="text/javascript" src="datediff.js"></script>
</head>

<body>

<script type="text/javascript">
var curDate=new Date();
startDate="2009-02-02";
endDate="2009-01-30";
curDate.DateDiff({interval:"d",date1:startDate,date2:endDate});
alert(curDate.difference);
</script>

</body>

<html>

<head>

</head>

<body>

var curDate=new Date();

startDate="2009-02-02";

endDate="2009-01-30";

curDate.DateDiff({interval:"d",date1:startDate,date2:endDate});

alert(curDate.difference);

</script>

</body>

Maka hasilnya akan ada alert berjumlah: -3
Hasil minus disini bisa berguna untuk cek validasi dan lain2.. sesuaikan dgn kebutuhan aplikasi kita.
