Navigation: navigateerror event

Baseline 2026
Newly available

Since January 2026, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The navigateerror event of the Navigation interface is fired when a navigation fails.

For example, if the network is down, any fetch() method invoked to handle a navigation will fail, and the error will be routed to navigateerror.

Syntax

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

js
addEventListener("navigateerror", (event) => { })

onnavigateerror = (event) => { }

Event type

An ErrorEvent. Inherits from Event.

Event ErrorEvent

Examples

You might deal with a successful navigation by hiding a previously displayed progress indicator, like this:

js
navigation.addEventListener("navigatesuccess", (event) => {
  loadingIndicator.hidden = true;
});

Or you might show an error message on failure:

js
navigation.addEventListener("navigateerror", (event) => {
  loadingIndicator.hidden = true; // also hide indicator
  showMessage(`Failed to load page: ${event.message}`);
});
