返回值:Deferred Objectdeferred.isResolved()

概述

确定延迟对象是否已得到解决。

jquery1.7API中已弃用,请用deferred.state()替代。

如果延迟对象是在被解决的状态则返回true,这意味着要么deferred.reject()或者deferred.rejectWith()被调用的对象和failCallbacks被访问(或称正在这一进程中的)。

请注意,延迟的对象可以有三种状态:未解决(unresolved),解决(resolved),或拒绝(rejected);使用deferred.isResolved()来判断延迟对象是否在解决状态 。这些方法主要用于调试时非常有用,例如,以确定是否递延已经解决,即使你在代码中打算拒绝。
