类式继承——代理函数模式(代理构造函数模式)

function inhert(C, P) {
    var F = function() {};
    F.prototype = P.prototype;
    C.prototype = new F();
    C.uber = P.prototype;
    C.prototype.constructor = C;
}

var inherit = (function{
    var F = function() {};
    return function(C,P) {
        F.prototype = P.prototype;
        C.prototype = new F();
        C.uber = P.prototype;
        C.prototype.constructor = C;
    }
}());
