onabort 只读特性在 FetchSignal interface is an event handler Invoked when an abort event fires, i.e. when the fetch request(s) the signal is communicating with is/are aborted.

句法

abortSignal.onabort = function() { ... };
					

范例

In the following snippet, we create a new AbortController object, and get its AbortSignal (available in the signal property). Later on we check whether or not it the signal has been aborted using the onabort property, and send an appropriate log to the console.

var controller = new AbortController();
var signal = controller.signal;
signal.onabort = function() {
  console.log('Request aborted');
};
