Chrome扩展程序-javascript无效

Question

I just started building chrome extension by looking at the google's example here: 我刚开始通过查看google的示例来构建chrome扩展：

I did exactly the same as mentioned above. 我做的与上面提到的完全相同。 Though I can see whatever i write in the body of my popup.html, it seems no section of the popup.js is working. 虽然我可以看到我在popup.html的主体中写的任何内容，但似乎popup.js的任何部分都没有。 I guess javascript is not working for my chrome extension. 我猜javascript对我的Chrome扩展程序不起作用。

I believe I follwed the CSP of Google but still. 我相信我已经完成了Google的CSP。 Thanks in anticiptaion. 谢谢你的期待。
