javascript - A small PC-side Tencent Weiyun front-end project written by a novice. Can you guys see what other details can be optimized or improved?

Question

I am a front-end student who has switched careers for about 6 months now, and I plan to find a job in the near future.

I have some own understanding of DOM operations, scopes, closures, functions, prototype objects, and AJAX. I dare not say if I have an in-depth understanding of it, but I can basically explain the ins and outs. Why do I only write native code? Because I can only write native and partial JQuery now... there are many tools, frameworks, modules, and engineering. In fact, I have not tried them in depth. I tried webpack a few days ago and I really feel that front-end tools are better than writing code. It's complicated in itself, but I still believe in a truth. The train is not as fast as the carriage in the beginning. Learning tools is conducive to production. Learning is really a never-ending road.

About Demo: Except for a few functional functions and JQ plug-ins (self-encapsulated), the rest are native JS. Let’s talk about the functions, tree menu area, file preview area, click interaction of navigation, pop-up box for moving and deleting files, add/delete/modify/move/frame selection function of folders, back-end part I don't know, so there is no database content, and the tree menu part is simulated data written by myself.

I hope you guys can give me some advice, thank you very much!

Answer 1

After creating a new folder, I clicked in and an error occurred. After that, your file tree expand and collapse function will fail
