Method: handsfree.on()

handsfree.on(eventName, callback, opts)

Listens to an event on the document with handsfree-${eventName}. This is basically a helper to:

document.addEventListener(`handsfree-${eventName}`, (event) => {
  callback(event.detail)
}, opts)

Because this is listening to events, the data will be in the event.detail property.

Parameters

eventName: string

(required) The event name to listen to, without the handsfree- prefix

callback: function

(required) The callback to call. Receives an event object

opts: object

(optional) Options to pass into addEventListener (opens new window), like {once: true}

Example

const handsfree = new Handsfree({hands: true})

// Work with data without creating a plugin
handsfree.on('data', (event) => {
  const data = event.detail
  console.log(data.hands)
})

handsfree.start()
