OnClickOutside Web Component

The on-click-outside is a custom web component built using LitElement. It dispatches a custom event ON_CLICK_OUTSIDE whenever a click is detected outside the content of this component.

See demo

Usage

1. Import the component:

import 'on-click-outside.ts';
import { ON_CLICK_OUTSIDE } from './on-click-outside.ts';

2. Use the component in your HTML:

<on-click-outside>
  <!-- Your content here -->
</on-click-outside>

3. Add an event listener for the ON_CLICK_OUTSIDE event:

document.querySelector('on-click-outside').addEventListener(ON_CLICK_OUTSIDE, () => {
  console.log('Clicked outside!');
});

Details

The component uses the connectedCallback and disconnectedCallback lifecycle methods to add and remove a click event listener on the body of the document. When a click event is fired, it checks if the click was outside the content of the component. If it was, it dispatches the ON_CLICK_OUTSIDE event.
