Adds multiple event listeners with the same handler to an element.
|
|
|
|
- Use `Array.prototype.forEach()` and `EventTarget.addEventListener()` to add multiple event listeners with an assigned callback function to an element.
|
|
|
|
```js
|
|
const addMultipleListeners = (el, types, listener, options, useCapture) => {
|
|
types.forEach(type =>
|
|
el.addEventListener(type, listener, options, useCapture)
|
|
);
|
|
};
|
|
```
|
|
|
|
```js
|
|
addMultipleListeners(
|
|
document.querySelector('.my-element'),
|
|
['click', 'mousedown'],
|
|
() => { console.log('hello!') }
|
|
);
|
|
```
