jQuery Library Conflict (TamperMonkey)

Hello all! I'm writing a short little script for a website I use frequently using TamperMonkey. I'm coding in jQuery, but the site uses a different library. These two libraries conflict and break some of the site's built-in coding (all my customizations work). I went through this https://learn.jquery.com/using-jquery-core/avoid-conflicts-other-libraries/ and it seemed perfect for what I was trying to do, but TamperMonkey insists that jQuery is an undefined function and cannot be used. When I force it to run on the site, it throws a console error as well. This is what I have so far, with the main code snipped since it's not relevent.

// ==UserScript==
// @name         {snipped}
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  {snipped}
// @author       You
// @match        {snipped}
// @require      http://code.jquery.com/jquery-3.7.1.min.js
// @icon         https://www.google.com/s2/favicons?sz=64&domain=pokefarm.com
// @grant        none
// ==/UserScript==

/* global jQuery */

jQuery.noConflict();

jQuery( document ).ready(function( $ ) { ... });

what are you using jQuery for?

Zach..•8mo ago

The code itself modifies the buttons on the site to stack over one another and disappear on click. The site is a petsim clicker game ^^

Jochem•8mo ago

but what specifically are you using jquery for? Just the $(css selector) functionality?

Zach..•8mo ago

I can paste the full code if you want it. I didn't think it would be needed :0

Jochem•8mo ago

most of what jquery was classically used for has been implemented in JS now, so you may not need it at all

Zach..•8mo ago

I couldn't get it to work in JavaScript classic at ALL. Likely because the selector was more confusing and i was doing it wrong.

so just to pick a random bit:

$("#notice").css({
    display: "none",
    userSelect: "none"
});

$("#notice").css({
    display: "none",
    userSelect: "none"
});

can be translated to

const notice = document.querySelector('#notice')
notice.style.display = 'none';
notice.style.userSelect = 'none';

const notice = document.querySelector('#notice')
notice.style.display = 'none';
notice.style.userSelect = 'none';

document.querySelector and document.querySelectorAll are pretty much drop in replacements for $()

Zach..•8mo ago

Is there no way to resolve a conflict though? I'd rather not translate it all if I can help it I definitely could if theres no way to resolve a conflict easily, but I'd be surprised if there wasn't

Jochem•8mo ago

hm, you probably can, but I don't personally know how

Zach..•8mo ago

Okay, thanks for letting me know! If I dont have anyone else figure it out I may come back for some help translating it all back to JS from jQuerry

Jochem•8mo ago

if there's a conflict, is $ just available in the tampermonkey script without including it?

Zach..•8mo ago

I don't think so, it rejects it unless you add /* global $*/

Jochem•8mo ago

hm, then I hope someone else who does know comes along 🙂 sorry I couldn't help

Zach..•8mo ago

It's okay! I still appreciate it ❤️
