有人会extjs的吗？麻烦帮我看一下
这是一个用extjs布局的js代码，主要是一个框架页面，想在左边显示一棵树，树的内容是从数据库动态读出来的，点击树的节点，在右边框架页里显示相应的内容。 先在框架页面通过下面的代码实现了，问题就是怎么把树显示在左边啊？？？？我是做。net开发的
<script type="text/javascript">
var tabpanel;
var index = 0;

[解决办法]
树可以放在单独一个html中，
你这已经分了west和center 也就是用了border布局，
west中的items:[tree]可以直接是树 也可以是一个html
items:[
html:'<iframe src="\\..\\tree.html"></iframe>'
]
