<h1>Blase im JavaScript-DOM</h1>
<p>DOM’s 的结构是:</p>
<pre><code>
UL
- LI
- A
- SPANNE
</code></pre>
<div>
<ul>
<li><a href="#"><span>Bubbllllllllllllllle</span></a></li>
<li><a href="#"><span>Bubbllllllllllllllle</span></a></li>
</ul>
</div>
<textarea></textarea>
<p>鼠标进入UL的任何一个子元素,如果不停止冒泡,我们从UL到SPAN都定义了鼠标悬停（<code>mouseover</code>）事件,这个事件会上升了UL,从而从鼠标所进入的元素到UL元素都会有红色的边.</p>
<div>
<ul>
<li><a href="#"><span>Bubbllllllllllllllle</span></a></li>
<li><a href="#"><span>Bubbllllllllllllllle</span></a></li>
</ul>
</div>
<p>如果停止冒泡,事件不会上升,我们就可以获取精确的鼠标进入元素.</p>
</body>
