If you’re adding JavaScript to your custom module it is very easy and tempting to simply add it like this: jQuery(document).ready(function($){   alert(‘hot dog flavored water’); }); Now this code works perfectly fine but what if your JavaScript needs to be executed on page load and after an AJAX request? Imagine you have a view that uses “Views Infinite Scroll” and you want add a CSS class to every result like this: jQuery(document).ready(function($){   $('.view-display-id-page .views-row').addClass('fancy-pants'); }); This will work for the results that are displayed initially but for all the results that are loaded by Infinite Scroll's AJAX call the class is not added. That’s where Drupal behaviors come in handy.  The behaviors will be executed on every request including AJAX requests, so let's do the equivalent of the code above but this time using this method: Drupal.behaviors.infiniteScrollAddClass = {   attach: function (context, settings) { ...

There are following changes in drupal7 and drupal8. 1. variable_set()/variable_get() are gone In Drupal 7, all variables are global, so accessing and saving them is done this way: // Load the site name out of configuration. $site_name = variable_get('site_name', 'Drupal'); // Change the site name to something else. variable_set('site_name', 'This is the dev site.'); In Drupal 8, configuration will only be lazy-loaded when needed. The above code would therefore change as follows: // Load the site name out of configuration. $config = config('core.site_information'); $site_name = $config->get('site_name'); // Change the site name to something else. $config->set('site_name', 'My Awesome Site'); $config->save(); 2. $_GET[‘q’] is gone The PHP super global key $_GET['q'] is 100% missing in Drupal 8, now you are forced to use the standard method current_path().
