Installation

1. Run: npm i @dpsys/stimulus-modal-window
2. Register this controller. This example uses vite-helpers. Use your own implementation if needed.

import { Application } from "@hotwired/stimulus";
import { registerControllers } from 'stimulus-vite-helpers'
import ModalWindow from "@dpsys/stimulus-modal-window";

const stimulusApp = Application.start();
const stimulusControllers = import.meta.glob('../**/*_controller.js', { eager: true })
registerControllers(stimulusApp, stimulusControllers);
stimulusApp.register('modal-window', ModalWindow);

3. If not using bundler like vite you have to manually load style.css

Usage

Basic window

This example uses Symfony, Twig and Tailwind. Use your own implementation if needed.

<button class="main" data-mw-opener-something>Open window</button> {# Name of data attribute can be anything. E.g.: data-foo-bar  #}

<div class="modal_window top-[15vh] right-[25vw]" {{ stimulus_controller('modal-window', {opener: '[data-mw-opener-something]'}) }}>

    <div class="modal_window_closer">X</div> {# Optional. Specify if needed. #}

    <div class="modal_window_content"> {# Optional. Gets created automatically if doesn't exist. #} 
        My content ...
    </div>
</div>

If a window needs to have it's own logic

1. Choose arbitrary name for a controller ... {{ stimulus_controller('mw-something', ...

2. Create such controller

// .../controllers/mw-something-controller.js
import ModalWindow from '@dpsys/stimulus-modal-window';

export default class extends ModalWindow
{
	connect()
	{
		super.connect();

		...
	}

	async customMethodOne()
	{	
        ...															
	}

	async openBeforeCallback()
	{
		alert('The window is going to open');
	}
}

Access elements inside controller

this.content - content wrapper

this.opener - clicked element used to open current window

this.closer - closer element

Methods

open()

Opens the window

close()

Closes the window

Callbacks

Define these methods in your extended class if you need to execute some code when the state of the window is being changed (see example above)

openBeforeCallback()

Do something before the window starts opening

openAfterCallback()

Do something after the window finishes opening

closeBeforeCallback()

Do something before the window starts closing

closeAfterCallback()

Do something after the window finishes closing

Settings

state : String

Default state of a window on page load.

Possible values: CLOSED (default), OPENED, OPENING, CLOSING

openDurationMs : Number

Opening duration in milliseconds

closeDurationMs : Number

Closing duration in milliseconds

opener : String

CSS selector of element/s which opens the window

clickOutsideIgnore : Array

Styling

.modal_window.closed {opacity: 0; transition: opacity 0.5s ease-in;}
.modal_window.opening {opacity: 1;}

.modal_window.opened {opacity: 1; transition: opacity 0.5s ease-out;}
.modal_window.closing {opacity: 0;}

Troubleshooting

Flash of unstyled content on page load

Add modal_window class to the main element:

<div class="modal_window top-[15vh] right-[25vw]" {{ stimulus_controller('modal-window', ...) }}>
