シンプルな継承パターン1

extend.sample1.js

Object.prototype.mix = function() {
    var c = Object.clone(this), prop, pprop, p;
    for (var i = 0, len = arguments.length; i < len; i++) {
        for (prop in arguments[i]) {
            c[prop] = arguments[i][prop];
        }
    }
    
    return c;
};

var Android = {
    init: function() {
        console.log("i am android phone user");
        return this;
    },
    
    getPhoneName: function() {
        return "android";
    }
};

var Iphone = {
    init: function() {
        console.log("i am iphone user");
        return this;
    },
    
    getPhoneName: function() {
        return "iphone";
    }
};

var Feature = {
    getPhoneType: function() {
        return "old";
    }
};

// デメリットはmixメソッドがObjectに勝手についてしまう
var o1 = Iphone.mix(Android).init();
//console.log(o1);

// 多重継承風(1)
var o2 = Iphone.mix(Android).mix(Feature);
//console.log(o2);

// 多重継承風(2)
var o3 = Iphone.mix(Android, Feature);
//console.log(o3);
