proper-event

Given an event type, automatically get the correct event class ('click' -> MouseEvent)

properEvent is meant to be used when you want to trigger a number of events in a loop or when the event type is user-provided. It avoids code like:

switch (type) {
    case 'click':
        event = new MouseEvent('click');
        break;
    case 'keydown':
        event = new KeyboardEvent('keydown');
        break;
    case 'submit':
        event = new Event('submit');
        break;
    default:
        event = new CustomEvent(type);
        break;
}

replacing it with:

const event = properEvent(type);

See the list of supported events in the ./index.js file. If the event is not known or not supported by the current platform, you will get a CustomEvent instance.

Install

npm install proper-event

Usage

import properEvent from 'proper-event';

const event = properEvent(prompt('What event should be triggered?'));

document.querySelector('a').dispatchEvent(event);

API

properEvent(type, init?)

Provide a type like 'click' and get the corresponding event instance, like new MouseEvent('click')

If none is found, you will get a CustomEvent instance.

import properEvent from 'proper-event';

const event = properEvent('click');

type

Type: string

The event type to be triggered, like 'click','submit', 'keydown', etc.

init

Type: EventInit

Optional

The event options, like { bubbles: true, altKey: true }. This is the same as the second argument of new Event(type, init).
