在对象函数内部并在调试器上暂停时，Javascript变量未定义

Question

更新：刚刚整理这篇文章，因为问题似乎略有改变。在断点上暂停时， Chrome 开发工具似乎无法正常工作。

编辑：更新了第一个示例，它似乎是chromes调试工具的问题。看来如果你在otherFunc中没有包含console.log语句并在调试器上暂停，那么变量是未定义的。它们应该在Firefox中正常工作。

var a = (function(window, document, undefined) {
    var View = {
        initialize: function() {
            // this prints
            console.log('started the view');
        },
    };
    var Controller = {
        start: function() {
            View.initialize();
            this.otherFunc();
        },
        otherFunc: function() {
            // try logging View and Controller in console
            debugger;
            // View and Controller are undefined

            // using console.log works eg console.log(View) does not give error.
        },
    }
    Controller.start();
})(window, document);

与以下相反，如果您包含控制台日志语句，则可以从chromes dev工具访问该变量。

var a = (function(window, document, undefined) {
    var View = {
        initialize: function() {
            // this prints
            console.log('started the view');
        },
    };
    var Controller = {
        start: function() {
            View.initialize();
            this.otherFunc();
        },
        otherFunc: function() {
            // We can now access View from the console while paused.
            debugger;
            console.log(View); // seems to fix the issue
        },
    }
    Controller.start();
})(window, document);
