jQuery deferred.isRejected()Methods
jQuery Miscellaneous MethodsDefinition and Usage
The deferred.isRejected() function is used to determine whether the Deferred object has been rejected.
Note:1. Deprecated as of jQuery 1.7.Please use deferred.state() instead. If the Deferred object is in the rejected state, it returns true. This means that deferred.reject() or deferred.rejectWith() has been called on the object, and failCallbacks have already been called (or are currently being called).
2. A Deferred object can have three states: pending, resolved, or rejected; use deferred.isResolved() to determine whether the deferred object is in the resolved state.
