RTCSctpTransport: statechange event

{{APIRef("WebRTC")}}

A statechange event is sent to an {{domxref("RTCSctpTransport")}} to provide notification when the {{domxref("RTCSctpTransport.state")}} property has changed.

Syntax

Use the event name in methods like {{domxref("EventTarget.addEventListener", "addEventListener()")}}, or set an event handler property.

addEventListener("statechange", (event) => { })

onstatechange = (event) => { }

Event type

A generic {{domxref("Event")}}.

Examples

Given an {{domxref("RTCSctpTransport")}}, transport, and an updateStatus() function that presents connection state information to the user, this code sets up an event handler to let the user know when the transport is connected.

pc.addEventListener("statechange", (event) => {
  switch (transport.state) {
    case "connected":
      updateStatus("Connection started");
      break;
  }
});

Using onstatechange, it looks like this:

transport.onstatechange = (event) => {
  switch (transport.state) {
    case "connected":
      updateStatus("Connection started");
      break;
  }
};
