NetworkInformation: change event

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Note: This feature is available in Web Workers.

The change event of the NetworkInformation interface fires when connection information changes, and the event is received by the NetworkInformation object.

Syntax

Use the event name in methods like addEventListener(), or set an event handler property.

js
addEventListener("change", (event) => { })
onchange = (event) => { }

Event type

A generic Event.

Examples

js
// Get the connection type.
const type = navigator.connection.type;
function changeHandler(e) {
  // Handle change of connection type here.
}
// Register for event changes:
navigator.connection.onchange = changeHandler;
// Another way: navigator.connection.addEventListener('change', changeHandler);
