js enum

方法1: 直接var定义

var Days = {"sunday" : 0, "monday" : 1, "tuesday" : 3, "wednesday" : 4, "thursday" : 5, "friday" : 6, "saturday" : 7};

document.write(Days.friday);

方法2: 用函数

function Enum() {}

Enum.ColorType = {red:0, blue:1, green:2}

document.write(Enum.ColorType.blue);

方法3: 用new 建立对像
var enumObj = new Object();

enumObj.fontSize = {small:10, medium:12, large:14}

document.write(enumObj.fontSize.small);
