Navigation: navigateerror event - Web APIs | MDN
Toggle sidebar
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
An ErrorEvent. Inherits from Event.
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}`);
});
