Removes an event listener from an element.
|
|
|
|
- Use `EventTarget.removeEventListener()` to remove an event listener from an element.
|
|
- Omit the fourth argument `opts` to use `false` or specify it based on the options used when the event listener was added.
|
|
|
|
```js
|
|
const off = (el, evt, fn, opts = false) => el.removeEventListener(evt, fn, opts);
|
|
```
|
|
|
|
```js
|
|
const fn = () => console.log('!');
|
|
document.body.addEventListener('click', fn);
|
|
off(document.body, 'click', fn); // no longer logs '!' upon clicking on the page
|
|
```
