Untuk penyesuaian format bisa dilakukan sendiri ya :D.
Nah, jika ingin lebih praktis banyak juga library yang sudah dibuat para orang budiman yang berbaik hati mau berbagi. Salah satu contohnya adalah accounting.js.
Penggunaannya cukup mudah berikut beberapa contohnya.
// Standard usage and parameters (returns string): accounting.formatMoney(number,[symbol = "$"],[precision = 2],[thousand = ","],[decimal = "."],[format = "%s%v"]) // Second parameter can be an object: accounting.formatMoney(number, [options]) // Available fields in options object, matching `settings.currency`: var options = { symbol : "$", decimal : ".", thousand: ",", precision : 2, format: "%s%v" }; // Example usage: accounting.formatMoney(12345678); // $12,345,678.00 accounting.formatMoney(4999.99, "€", 2, ".", ","); // €4.999,99 accounting.formatMoney(-500000, "£ ", 0); // £ -500,000 // Example usage with options object: accounting.formatMoney(5318008, { symbol: "GBP", precision: 0, thousand: "·", format: { pos : "%s %v", neg : "%s (%v)", zero: "%s --" } }); // Will recursively format an array of values: accounting.formatMoney([123, 456, [78, 9]], "$", 0); // ["$123", "$456", ["$78", "$9"]]Gitu aja :D. Sampai jumpa di lain post. Thanks
