{{ApiRef("DOM")}}{{SeeCompatTable}}

The PromiseResolver interface represents an object controlling the state and the result value of a {{domxref("Promise")}}.

Properties

No specific property.

Methods

Doesn't inherit any method.

{{domxref("PromiseResolver.fulfill()")}}
Sets the result value of the associated Promise to the parameter and its state to fulfill. Call the fulfill callbacks or, if the asynch parameter is set to true, queue a task to call them.
{{domxref("PromiseResolver.resolve()")}}
...
{{domxref("PromiseResolver.reject()")}}
Sets the result value of the associated Promise to the parameter and its state to rejected. Call the reject callbacks or if the asynch parameter is set to true, queue a task to call them.

[1] Nightly of Gecko 24 got an experimental implementation of PromiseResolver, under the initial name of FutureResolver. It got renamed to its final name in the Gecko 25. To disable it, the preference dom.promise.enabled (in Gecko 24, dom.future.enabled) must be switched to false. Note, only Nightly and Dev Edition versions of Firefox get this interface enabled by default. Beta and Release versions of Gecko have them disabled by default.
