<p>我们可以用 <code>

|

<p>这个方法对 <a href="/trigger">trigger()</a> 来自定义的事件同样有效。</p>

<h3>Additional Notes:（其他注意事项：）</h3>
|
||
<div class="longdesc"><ul>
|
||
自从<a href="/live"><code>.live()</code></a>方法处理事件一旦传播到文档的顶部，live事件是不可能停止传播的。同样地，<a href="/delegate"><code>.delegate()</code></a> 事件将始终传播给其中包含的被委托元素；
|
||
元素上的事件将在被委托事件被调用的时候执行。因此，这些处理程序，可以调用<code><a href="/event.stopPropagation">event.stopPropagation()</a></code>或者返回<code>false</code>防止委派处理程序冒泡。
