We can think about two options: one more secure than other. First part: We create a welcome message and two buttons: one to start an image search process and another one to clean the image board generated from the search and the results. This is where your ability to use your working IDEs search engines in order to locate behaviors through the console comes into play, looking for: You will discover some libraries that have been added to the Theme in general and that should really only be added by #attached to only one specific page, for example. Well, this article was made for you (Or for other people in your team that you want to introduce to this topic). Lets see the new file custom_dialog_window.js : You can review all the JavaScript associated with the global object Drupal thanks to the great documentation Thodore Biadala (@nod_) published years ago about the Drupal JavaScript API: http://read.theodoreb.net/drupal-jsapi/index.html. Teams. To do this well use the Drupal Devel Module and its Devel Generate sub-module to create test content, adding new commands and sub-commands to Drush. yml file. It's "dynamic" because you can use logic to control this attaching of the libraries. We can rename the custom module if we want, to particularize it a bit more (Ill use the naming javascript_custom_module to avoid confusion with other test modules. Apply filter criteria, check and select content types EDM albums. Of course, very rarely, there is a valid reason to actually load a certain asset on all pages (e.g. And dont forget to consider jQuerys recommendations for good use. For that, well create a /js folder and will put inside our new file hello-world.js wich contains our new library with a little action, just say hello by Console: So the internal structure of our custom module for testing should look like this: Now our goal is linking the new library with its JavaScript .js file associated with the context in which it should work, right? Just a little intuitive game. We will declare the new dependency in the usual *.libraries.yml file: In this case we will try to load the new library through a hook of type hook_page_attachments() inside the file javascript_custom_module.module: And in the folder js/ we will create the new file playing_with_jquery.js , in which we will dump all our mandanga. A couple of months later, in February 2020, I had a tutorial of more than eleven thousand words written in Castillian (Spanish from Spain) that I published in my Medium profile. In this tutorial, although it is not an advanced JavaScript manual, we will use this language in several sections, so is great that you know it a little bit. Drupal: Our technological platform of reference in this context. Render arrays are cached. You might want to use JavaScript that is externally on a CDN (Content Delivery Network) to improve page loading speed. Can I use the spell Immovable Object to create a castle which floats above the clouds? "Attach" the library to a render array in a hook. Inline JavaScript is highly discouraged. The main one: that the modules that want to implement JavaScript must do so by adding logic to the Drupal.behaviors Object. - fluffiness/cuddly-slider. ;-). In each case, a processing of behaviors is done through the method: Which loads a function that runs through all the behaviours and executes them according to their context and parameters: The next step is to put some control on the execution of the instruction, passing it from an active mode (that writes in the console just when loading) to a reactive mode (that writes only when an interaction takes place): So now we have placed over the ID selector of our welcome message a click control event, which when clicked loads a message into the console: With this small example above, we have seen how to add a small event-based (click) functionality.
