Question

Здравствуйте. В приведенном ниже коде есть одна проблема: внутри функции qux() невозможно получить доступ к свойству объекта bar. Подскажите, каким образом можно это решить?


function foo(){

this.bar;

this.baz = function(){

function qux(){
this.bar += 10;
alert(this.bar);
};
qux();

};

};

var x = new foo();
x.bar = 33;
x.baz();
