AbortSignal: abort event

Syntax

Use the event name in addEventListener():

addEventListener("abort", (event) => { })

Alternatively, assign to the event handler property of the interface:

onabort = (event) => { }

Event type

A generic Event with no added properties.

Examples

In the following snippets, we create a new AbortController object, and get its AbortSignal (available using the signal property). Later on we check whether or not the signal has been aborted using an event handler property,

You can detect the abort event using an addEventListener method:

const controller = new AbortController();
const signal = controller.signal;

signal.addEventListener("abort", () => {
  console.log("Request aborted");
});

Or use the onabort event handler property (but note that this replaces other event listeners added using onabort, if any):

const controller = new AbortController();
const signal = controller.signal;

signal.onabort = () => {
  console.log("Request aborted");
};
