function MagicObject() {

    return new Proxy(this, {
        get: function (target, name) {
            if (name in target) {
                return target[name];
            } else {
            	var ret = function(){
            		if('__call' in target){
            			return target.__call(target, name);
            		}
            	}
            	ret.toString = function(){
            		'[not implemented]'
            	}
            	return ret;
            } 
        }
    });
}

var obj = new MagicObject();

obj.__call = function(target, name){
	alert('调用了魔术方法:' + name);
	if(name == 'a'){
		return 'hello world';
	}
}

obj.c = function(){
	return '没有调用魔术方法:c';
}

alert(obj.a());
alert(obj.b());
alert(obj.c());
alert(typeof obj.e);
</script>

真是高级啊

高端大气上档次
