<p>除了阻止元素上其它的事件处理函数的执行，这个方法还会通过在内部调用 <code>event.stopPropagation()</code> 来停止事件冒泡。如果仅仅想要停止事件冒泡到祖辈元素上，而让这个元素上的其它事件处理函数继续执行，我们可以使用 <code>
|
||
<a href="/event.stopPropagation">event.stopPropagation()</a>
|
||
</code> 来代替。</p>
|
||
<p>使用 <code>
|
||
<a href="/event.isImmediatePropagationStopped">event.isImmediatePropagationStopped()</a>
|
||
</code> 来确定这个方法是否(在那个事件对象上)调用过了。</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。
