NavigateEvent: signal property
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 signal read-only property of the
NavigateEvent interface returns an AbortSignal, which will become aborted if the navigation is cancelled (e.g., by the user pressing the browser's "Stop" button, or another navigation starting and thus cancelling the ongoing one).
Value
An AbortSignal object.
Examples
The general idea here is that the signal property can be passed to an associated fetch() operation so that if the navigation is cancelled, the fetch() operation can be safely aborted, avoiding wasting bandwidth on fetches that are no longer needed.
navigation.addEventListener("navigate", (event) => {
event.intercept({
async handler() {
// …
await fetch(`/img/some-image.jpg`, { signal: event.signal });
// …
},
});
});
Note: See Example: next/previous buttons for a more detailed example.
