从jQuery1.7开始，这个 API已经过时;
|
||
请使用<a href="/deferred.state"><code>deferred.state()</code></a> 代替。</p>
|
||
<p>如果Deferred（延迟）对象是在被拒绝的状态，则返回<code>true</code>，这意味着要么<code><a href="/deferred.reject">deferred.reject()</a></code>或者<code><a href="/deferred.rejectWith">deferred.rejectWith()</a></code>已经在对象上被调用过，并且 failCallbacks 已经被调用过（或者正处于被调用的阶段）。</p>
|
||
<p>请注意，Deferred（延迟）对象可以有三种状态：挂起（pending），解决（resolved），或拒绝（rejected）;使用<code><a href="/deferred.isResolved">deferred.isResolved()</a></code>来判断延迟对象是否在解决状态。这些方法在调试时非常有用，例如，以确定是否递延已经解决，即使你在代码中打算拒绝。
