TCPSocket.onclose

Summary

The onclose property is used to specify an event handler to receive close events. Those events are triggered when the server or the client (with the close() method) closes the connection.

Syntax

instanceOfTCPSocket.onclose = funcRef

Where funcRef is a function to be called when the close event occurs.

This callback function will get a TCPSocketEvent object as its first parameter.

TCPSocketEvent

Such events are simple JavaScript objects with the following properties:

target

The TCPSocket object which fired the event.

type

A string defining the type of the event. Its value can be one of the following: open, error, data, drain, or close.

data

The data related to the event, if any.

Specification

Not part of any specification yet; however, this API is discussed at W3C as part of the System Applications Working Group under the Raw Sockets proposal.
