The unhandledrejection
event is fired when a JavaScript Promise
is rejected but there is no rejection handler to deal with the rejection.
Bubbles | No |
Cancelable | No |
Target objects | defaultView |
Interface | PromiseRejectionEvent |
Examples
window.addEventListener("unhandledrejection", function (event) { console.warn("WARNING: Unhandled promise rejection. Shame on you! Reason: " + event.reason); });
Inheritance
The unhandledrejection
event implements the PromiseRejectionEvent
interface, which inherits from Event
. You can use the properties and methods defined on these interfaces.
