jQuery deferred.isResolved () method
Definition and Usage
deferred.isResolved () function is used to determine whether a Deferred object has been resolved.
Note: 1. From the start jQuery1.7 outdated, please use deferred.state () instead. If Deferred (delay) the object is being solved state, returns true. This means deferred.resolve () or deferred.resolveWith () has been called on the object, and doneCallbacks has been called (or is in the stage of being called).
2. Deferred (delay) object can have three states: Pending (pending), solve (resolved), or denied (rejected); use deferred.isRejected () to determine whether the object is a delay in the state of denial.
