Rails 6, Stimulus events

An action is a connection between:

• a controller method
• the controller’s element
• a DOM event listener

gallery_controller.js

// controllers/gallery_controller.js
import { Controller } from "stimulus"

export default class extends Controller {
  next(event) {
    alert("Justclick !!! :")
  }
}

View File Setup

<div data-controller="gallery">
  <button data-action="click->gallery#next">…</button>
</div>

Descriptors

The data-action value click->gallery#next is called an action descriptor. In this descriptor:

• click is the name of the DOM event to listen for
• gallery is the controller identifier
• next is the name of the method to invoke

The full set of these shorthand pairs is as follows:
