Example 1 (for drupal 7)

Step 1. Add file brows

Create a simple js file in your module directory (called yourModuleName.js) and enter the following Javascript.

Disable cache for a custom page from route declaration.

If you want to disable cache for a custom controller (Custom module), You have no_cache option (YOUR_MODULE.routing.yml).
Example :
File : mymodule.routing.yml

On drupal 8 every elements (almost) are an entity, as any entity you can render a node.

First, Create autocomplete controller and the route

Example of the controller : DefaultController.php

<?php

namespace Drupal\mymodule\Controller;
