Overview

On this page, we introduce how handlers can be attached to various Kintone events. The different types of Kintone events are listed in the side menu.

Register Event Handlers - kintone.events.on(type, handler)

Registers an event handler.

Function

kintone.events.on(type, handler)

Parameters

PARAMETER VALUE REQUIRED DESCRIPTION
type A string or an array of strings Yes The event type or array of event types, to which the event handler will bind to.
handler Function(Object) Yes The handler that will run when the event is triggered.
