JavaScript 演練(1). 定義一組常量或一組函數

在看幾個 js 源碼; 感覺不如 Delphi 的代碼清晰, js 太靈活性, 需慢慢適應.

/* 定義一組常量(變數) */var MX1 = function () { };MX1.Max = 100;MX1.Min = 0;MX1.Ave = 50;alert(MX1.Max + ", " + MX1.Min + ", " + MX1.Ave); //100, 0, 50alert(++MX1.Max); //101/* 定義一組函數 */var MX2 = function () { };MX2.Add = function (a, b) { return a + b; }MX2.Dec = function (a, b) { return a - b; }MX2.Mul = function (a, b) { return a * b; }MX2.Div = function (a, b) { return a / b; }var x = 6,    y = 3;alert(MX2.Add(x, y)); //9alert(MX2.Dec(x, y)); //3alert(MX2.Mul(x, y)); //18alert(MX2.Div(x, y)); //2
