Is .js extension needed for Javascript files in browser?

Question

Can things like <script type="text/javascript" src="/actions/generateScript"></script> be used without troubles?
It's kinda hard and tricky to setup server for processing urls with extensions, so maybe I just don't need them.

Answer 1

No, it's not needed. Browser just tries to download resource from src and execute it as JS code.

I once have use .php file as CSS source and it worked fine

Answer 2

不，因为你已经有了“script type =”text / javascript“浏览器知道你正在尝试加载.js文件。此外，现代浏览器无论如何都会运行javascript。
