Navigation: navigateerror event

Limited availability

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

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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

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}`);
});
