Hello. I am new. Can you guys tell me how can i learn?

Hello. I am new. Can you guys tell me how can i learn? I interested to making scripts but idk how i can learn. Can you guys tell me what i must do and not do?

Many thanks.

 

There's a guide at the very top of this forum. The thread is here (click me).

 

And it says $ is undefined. But i did;
// @require https://code.jquery.com/jquery-3.0.0-alpha1.min.js

@Pyper

 

Put this as your first line.

var $ = window.jQuery;

I'm still new to writing scripts, but I'll try to help out where I can.

 

You should never have to do that (setting $). Include something more recent. Here's the most recent prod version for jQuery https://code.jquery.com/jquery-3.3.1.min.js.

 

Tampermonkey still says that it's not defined. Scripts will still work though even with the error.

 

Oh, the linter in the editor is saying that? The linter is wrong. It just doesn't know about the global variable being added from the @require. You need to add this to the top of the script under the metadata.

Code:

/* globals $ */

Then it will look like.

 

That fixed it, thank you!
