一个 <UL><LI>  我用LI定义为块  当鼠标靠近时激活onmouseover的时候 如何定义LI的高度呢

<ul style="list-style:none;"> <li onmouseover="this.style.height='30px'" onmouseout="this.style.height='auto'">测试内容</li> <li onmouseover="this.style.height='30px'" onmouseout="this.style.height='auto'">测试内容</li> <li onmouseover="this.style.height='30px'" onmouseout="this.style.height='auto'">测试内容</li> <li onmouseover="this.style.height='30px'" onmouseout="this.style.height='auto'">测试内容</li> <li onmouseover="this.style.height='30px'" onmouseout="this.style.height='auto'">测试内容</li> <li onmouseover="this.style.height='30px'" onmouseout="this.style.height='auto'">测试内容</li> </ul>
 提示：您可以先修改部分代码再运行

做了个比较丑的效果~
仅供参考啊
