第一个，用到的js,不过很短，也很明了
<style> *{font:normal normal 14px/1.5em "宋体";} li{list-style:none;} span{display:block;line-height:25px;} a{text-decoration:none;display:block;margin:5px;} .class1{ width:100px; height:25px; overflow-y:hidden; border:1px solid #ffe663; text-align:center; background:#fff2d9; } .class2{ width:100px; height:135px; overflow-y:hidden; border:1px solid #ffe663; text-align:center; background:#fff2d9; } a:hover{ border:1px dashed red; } </style><li onmouseover="this.className="class2"" onmouseout="this.className="class1"" class="class1"> <span>下挂菜单</span> 万水千山万种风情万山千水万马奔腾 </li>
