Subscriptions

Subscriptions allow you to automatically call desired functionality in response to some events happening with SDK integrations. The exact list of events is defined by integration type. See the exact subscription list for click listeners and widgets.

In order to create a new subscription call whisk.events.subscribe(element_id, event_name, callback) function, which will call callback function when an event with event_namehappens for DOM element with element_idid attribute.

A callback function will be called with a single argument which has the following type definition:

ATTRIBUTE

TYPE

DESCRIPTION

type*

string

Type of the event.

data

object

It contains data custom for each particular event.

In order to remove the subscription call whisk.events.unsubscribe(element_id, event_name, callback) function.
