jQuery Question

Ruby on Rails || Jquery and JavaScript libraries not working

I've created a page on Codepen to be later added to my Ruby on Rails app ( https://codepen.io/salman15/pen/evQVLV ), where all the code works fine.

After creating the page I tried adding the page to my Ruby on Rails app with spree (which is running on Cloud 9 https://consulegem-salman15.c9users.io/ "server might not be offline at the time that you read this"). I've done this in the following manner:

Step 1: Added the html code to the

index.html.erb


Step 2: Added the CSS CDN to the
_head.html.erb


Step 3: Downloaded all the JavaScript libraries and added them in the following folder path -> app -> assets -> javascripts -> frontend -> store

step 4: added the following line of code to my all.js file (inside in the frontend folder)

//= require_tree


At this point my code should have been working, yet it doesn't.

It bugs me that the exact same code with the exact same libraries doesn't seem to work on my Ruby on Rails app, and it phantom's me why?

The error
is not a function
occurs because the code isn't recognized, normally this is caused because the libraries isn't loaded. Yet I checked the source page after te page has been loaded and the all libraries are loaded.

The TweenMax errors also phantom's me because it's the same libraries and the same code.

I've tried several solutions, like adding the library code to my script.js and it seemed to work, but this would be an improper solution.

I think I've all needed information and code, but if you need any more feel free to ask.

To summarize my question:

Problem: My Jquery libraries don't seem to work

Question: why?

script.js

//MENU

var wrap = $("#main-nav-bar");

wrap.on("scroll", function(e) {
if (this.scrollTop > 147) {

} else {

}
});

Answer Source

According to the files you've pasted, the libraries are being loaded in the wrong order. I suspect that the following line should be moved to the end of your application.js manifest, to ensure that it gets loaded only after all the jQuery plugins are. Something like:

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .

Be advised, that require_tree does not guarantee the order in which your custom scripts are loaded. So you can still end up with these issues if one script is dependent on the other. You should try to write standalone scripts, so that the order of execution doesn't matter. If you absolutely must write scripts dependent on each other, then you should lean towards importing them in the correct order in your manifest manually.

Also, you imports look wrong. You appear to have imported jQuery thrice. You should paste the contents of the <head> tag in the final rendered page in development mode to ensure that this is actually working.

//= require_jquery.min <-- second import!
//= require_jquery-3.2.1.min <-- third import!
//= require_jquery.easeScroll
//= require_jquery.logosDistort.min
//= require_jquery.particleground.min
//= require_jquery.jquery.scrollmagic.min

Try:

//= require jquery.easeScroll

After adding the relevant gems to your Gemfile, of course.
