Runs the callback whenever the user clicks outside of the specified element.
|
|
|
|
- Use `EventTarget.addEventListener()` to listen for `'click'` events.
|
|
- Use `Node.contains()` to check if `Event.target` is a descendant of `element` and run `callback` if not.
|
|
|
|
```js
|
|
const onClickOutside = (element, callback) => {
|
|
document.addEventListener('click', e => {
|
|
if (!element.contains(e.target)) callback();
|
|
});
|
|
};
|
|
```
|
|
|
|
```js
|
|
onClickOutside('#my-element', () => console.log('Hello'));
|
|
// Will log 'Hello' whenever the user clicks outside of #my-element
|
|
```
