<p>deferred.state() 方法返回一个字符串，代表Deferred（延迟）对象的当前状态。Deferred对象可以在三种状态之一：</p>
|
||
<ul>
|
||
<ul>
|
||
<li>
|
||
<strong>"pending"</strong>: Deferred对象是尚未完成状态 (不是 "rejected" 或 "resolved").</li>
|
||
<li>
|
||
<strong>"resolved"</strong>: Deferred对象是在解决状态，这意味着，<a href="/deferred.resolve"><code>deferred.resolve()</code></a> 或者 <a href="/deferred.resolveWith"><code>deferred.resolveWith()</code></a>被对象访问和doneCallbacks被访问（或在被调用的过程中） 。 </li>
|
||
<li>
|
||
<strong>"rejected"</strong>: Deferred对象是在被拒绝的状态，这意味着，<a href="/deferred.reject"><code>deferred.reject()</code></a> 或者 <a href="/deferred.rejectWith"><code>deferred.rejectWith()</code></a> 被对象访问和failCallbacks被访问（或在被调用的过程中） 。</li>
|
||
</ul>
|
||
<p>这种方法主要是有用的调试，例如，在准备拒绝（reject）一个延迟对象前，判断它是否已经处于 resolved 状态。</p>
