Ruby on Rails || Jquery and JavaScript libraries not working

Question

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

ANSWER

You can find the answer in the answer downbelow, but it's not the only part of the answer. The final part of the answer was in the CSS, there was a conflict in my body causing part of the error. So if you're having the same issue, make sure your Libraries are loaded at the proper position(bottom for me) and proper order. Also make sure your CSS isn't causing any errors as wel.

Ingamar

This is most likely an issue with the order in which scripts are being loaded by the asset pipeline. Can you post the contents of your <head> tag in development mode, as well as your application.js manifest file? – Derwood

Agreeing with @Derwood the guide says "the order in which files are included by require_tree is unspecified. You should not rely on any particular order among those. If you need to ensure some particular JavaScript ends up above some other in the concatenated file, require the prerequisite file first in the manifest." So it seems very likely it's a file order issue – Damask

Which is why you should show us the contents of you <head> tag in development mode. The pipeline serves each asset individually in development, and so that should make the ordering issue obvious. – Derwood

First of Thank you @Derwood and simpleLime for your responses. I've added the requested files. I think I understand what you mean. The Libraries are getting loaded in the wrong order. – Ingamar

Answer 1

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.

Derwood

I've changed the file and even removed the require_three part to ensure that the libraries get loaded in the proper way. Put I still get the same errors :\ I've added the new application.js to the question – Ingamar

In development mode, could you paste the contents of the <head> tag in the final html that gets rendered? I'm positive you can identify the exact problem. Also, the require_jquery.min... look wrong. Is the syntax correct? Why have you imported jQuery thrice? Should it not be require jquery.pluginName? – Derwood

After removing the _ some of the libraries seem te get loaded, yet there is still a conflict, also I've added the content of the renderd head tag (not everything, because of the max characters in a question). – Ingamar

I don't see your javascript anywhere in the rendered <head> tag. Are you sure you've put it in the right place? – Derwood

I've added it to the question, It seems it is loaded after all my other code. I will try to see the order in with it is loaded on my codepen, also is it not better to put the code in the footer? – Ingamar

You're still loading jQuery twice. Could be a conflict. Try removing one of the includes, methinks getting rid of the second one should fix it. Also, check your browser console to see if any of the requested scripts are empty / fail to load. – Derwood

I've found the problem. It's that all the libraries and my own script is being loaded at the top of the page. It needs to be loaded in the footer. The I've tried adding the script tag at the bottom of the page, but. Then the spree script doesn't work anymore because some of the scripts of spree need to run at the top. – Ingamar

I've managed to get my scripts loaded at the bottom of the page, but my code still doesn't work.. if i add $("body").css('display','none'); to the top of my code it gets exucute it. so my code gets read, if i remove a library it gets removed, but my code just doesn't get executed – Ingamar

Okay, do this. Comment out your whole custom script. Put a console.log ("Hello, World") in there. Then experiment with what we've discussed until you start seeing Hello, World in your console. – Derwood

I found the solution it's partly what you said, but there was also a conflict in my css for some reason. – Ingamar

Triple check your includes. There are probably mistakes in your stylesheet manifest as well. – Derwood
