哪位帮忙给个JS高亮显示的代码，和2级级联的下来列表选择框50分

摘要: 哪位帮忙给个JS高亮显示的代码，和2级级联的下来列表选择框50分

我有个表单，我想让鼠标放在某个记录上的时候能高亮显示这个记录，还有我想要个2级级连的下拉列表选择框要完整能运行代码，原来我有放到哪里找不到了，还请各位帮个忙！

先赚点分, 解决第一个问题:
<input type="text" onmouseover="this.style.background='#ddf'" onmouseout="this.style.background='#fff'" />

二级联动没有什么难的, 主要是将树形结构保存在js中:
node[id] = [parentId, name];
