SyncEvent.SyncEvent()

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The SyncEvent() constructor creates a new SyncEvent object.

Syntax

var mySyncEvent = new SyncEvent(type, init)

Parameters

type
The type of the Event.
init Optional
An options object containing any custom settings that you want to apply to the event object. Options are as follows:
  • tag: A developer-defined unique identifier for this SyncEvent.
  • lastChance: A Boolean indicating that the user agent will not make further synchronization attempts after the current attempt.
