Triggers a specific event on a given element, optionally passing custom data.
|
|
|
|
Use `new CustomEvent()` to create an event from the specified `eventType` and details.
|
|
Use `el.dispatchEvent()` to trigger the newly created event on the given element.
|
|
Omit the third argument, `detail`, if you do not want to pass custom data to the triggered event.
|
|
|
|
```js
|
|
const triggerEvent = (el, eventType, detail) =>
|
|
el.dispatchEvent(new CustomEvent(eventType, { detail }));
|
|
```
|
|
|
|
```js
|
|
triggerEvent(document.getElementById('myId'), 'click');
|
|
triggerEvent(document.getElementById('myId'), 'click', { username: 'bob' });
|
|
``` |
