I have created a web application that takes input from a user, queries an API, processes the data with PHP and then presents it as a series of graphs using jQuery and D3. I initially set this up in a procedural manner but have since been implementing it using the Laravel framework. The problem I am having is that the JavaScript is not working properly in the final page; I think it has something to do with the way the Blade template system works.
I know that it is accessing the JavaScript file correctly as it loads up the initial graphs. However there is some extra functionality to reload the graphs according to different time spans and also to scroll through the data in the graphs. After it has loaded the page, none of the jQuery stuff is working.
Anyway, here is the code:
ROUTING: routes.php (app\Http)
<?php
// perform GET request on root and call method 'index' on the PagesController class
// (app/Http/Controllers/PagesController.php)
Route::get('/', 'PagesController@index');
// perform POST on 'data' and call method 'process' on the PagesController class
Route::post('data', 'PagesController@process');
?>

I went over my char limit so had to cut out some of the code but I think I've left what's important to identify the problem.
Basically it loads the page with the graphs fine, but if you try to load new graphs with the #timeSelect dropdown or scroll through the data with #next1, nothing happens.
Let me know if you need any more info - thanks.
** ADDITIONAL INFO **
I used https://github.com/laracasts/PHP-Vars-To-Js-Transformer in order to get my data to the view to load the graphs. When you use this it publishes a file to config called javascript.js. I have changed this to accommodate my app, but this could be where I'm going wrong. This is my amended file:
javascript.php (config)
return [
'bind_js_vars_to_this_view' => 'pages.data',
'js_namespace' => 'Graphs'
];

Please re-check if you have added defer in your app script or not. If you have used laravel-mix and added jQuery there make sure your app.js dont have a defer attribute.
I found Laravel calls the jquery when you set up a navbar / log in system . In the header you will find : Show activity on this post. Maybe your $ (document).ready (); is executing earlier than it should
JQuery Error Message $ is not defined in Laravel blade view template - Just Another Sharing Site ... This is an article written in order to explain on solving an error message popped in a plugin added or installed in a Web Browser specific which in this context is Mozilla Firefox. It is an error presented in a plugin named Firebug.
Also check the your jquery.min.js was load or not, Some time happens to our scripts was load first and after our jquery file so our script does not work propper.So I prefer to load first our jquery.min.js file and then our custom javascript files. Show activity on this post. This worked for me. jquery was loading fine but not working.
Most likely you are trying to access an element that is not ready, #next is not working and is also not wrapped. Just wrap all your code in $( document ).ready()
$( document ).ready(function() {
});
or place all your code in the bottom of the page - $(document).ready(function(){}); vs script at the bottom of page

You have posted a lot of code, and not the specifics on what is failing. Anyways, my suggestion is try to have your Javascript Code after all HTML code, using blade or not, order matters. So, you need to be sure you are calling all the libraries before executing your javascript code, and do all that preferrably after your html code is already rendered (at the end of the footer).

Try changing:
selector.on("change", function(e) {
for:
$(document).on('change', '#timeSelect', function(e) {
Maybe your $(document).ready(); is executing earlier than it should

This worked for me. jquery was loading fine but not working. Iam not sure you need to call the bootstrap and jquery scripts as laravel includes them .
I found Laravel calls the jquery when you set up a navbar / log in system . In the header you will find :
<script src="{{ asset('js/app.js') }}" defer ><script>
i just deleted 'defer' and jquery kicked in.
<script src="{{ asset('js/app.js') }}" ></script>
