javascript代码运行结果题

var myObject = {    foo: "bar",    func: function() {        var self = this;        console.log("outer func:  this.foo = " + this.foo);        console.log("outer func:  self.foo = " + self.foo);        (function() {            console.log("inner func:  this.foo = " + this.foo);            console.log("inner func:  self.foo = " + self.foo);        }());    }};myObject.func();

以上代码将在控制台输出：

outer func： this.foo = bar

outer func： self.foo = bar

inner func： this.foo = undefined

inner func： self.foo = bar
