<div class="longdesc" id="entry-longdesc">
<p>每当一个Ajax请求完成，jQuery检查是否有任何其他响应过程中的Ajax请求（注：未完成的请求）。如果都执行完成，jQuery就会触发<code>ajaxStop</code>事件，在这个时间点所有处理函数都会使用<code>.ajaxStop()</code>方法注册并执行。如果一个未处理完成的Ajax请求用<code>beforeSend</code>回调函数返回<code>false</code>取消，<code>ajaxStop</code>事件也被触发</p>
<p>观察这种方法，建立一个基本的Ajax加载请求：</p>

<p>在document上绑定事件处理器：</p>

<div class="line n1">1</div>
<div class="line n2">2</div>
<div class="line n3">3</div>

<td class="code">

</div>
<p>现在，我们可以使用任何的jQuery方法构建一个Ajax请求：</p>
<div class="syntaxhighlighter javascript nogutter">
<table>
<tbody>
<tr>
<td class="gutter">
<div class="line n1">1</div>
<div class="line n2">2</div>
<div class="line n3">3</div>
</td>
<td class="code">
<pre><div class="container"><div class="line"><code>$( <span class="string">".trigger"</span> ).click(<span class="keyword">function</span>() {</code></div></div><div class="container"><div class="line"><code>  $( <span class="string">".result"</span> ).load( <span class="string">"ajax/test.html"</span> );</code></div></div><div class="container"><div class="line"><code>});</code></div></div></pre>
</td>
</tr>
</tbody>
</table>
</div>
<p>当我们点击class为 <code>trigger</code> 的元素并且Ajax请求完成，这个信息就会显示。
			    </p>
<p><strong>但是从 jQuery 1.8 开始, <code>.ajaxStop()</code> 方法只能绑定到 <code>document</code>元素.</strong></p>
</div>
<h3>其他注意事项：</h3>
<div class="longdesc"><ul>
<li> 
			  如果<code>global</code>选项设置为<code>false</code>，调用<code><a href="/jQuery.Ajax">$.ajax()</a></code> 或 <code><a href="/jQuery.ajaxStop">$.ajaxStop()</a></code>方法将不会被触发。</li>
</ul></div>
