不幸的是，它将导致图5所示的错误消息，因为在dojo . forEach方法调用中声明的函数创建了一个闭包，该闭包将this定义为引用它本身。

Unfortunately, it will result in the error message shown in Figure 5, because the function declared in the dojo.forEach method call creates a closure that defines this as referring to its own body.

- Well, just a moment ago, we did have -- -- and this time I'll use some chalk here -- a moment ago, we did have a picture depicting what was going on when you call the function.

好的，刚才，我们确实有-,这一次我将用一些粉笔-,刚才，我们有一张图描绘了当我们调用函数的时候,会发生什么事情。
