我树我树我树树树（struts2 ext2.0）

不要只看你的return 前面的，
在你的浏览器里输入你的链接。，然后查看HTML页面源代码，仔细看看吧！呵呵，一定有一些没用的html的东西吧！

什么意思啊？不太懂   我的jsp是个空的啊
  里面就是树的js代码
这是树jsp的页面源代码<html>
<head>
<title>模块管理---树</title>

<link rel="stylesheet" type="text/css"
href="../js/ext2/resources/css/ext-all.css" />
<script type="text/javascript"
src="../js/ext2/adapter/ext/ext-base.js"></script>

<script type="text/javascript" src="../js/ext2/ext-all.js"></script>
<link rel="stylesheet" type="text/css" href="edit-grid2.css" />
<script type="text/javascript">
Ext.onReady(function(){
var Tree = Ext.tree;

      var tree = new Ext.tree.TreePanel({
    el:'tree-div',
    autoScroll : true,
             animate : true,
            enableDD : true,
             containerScroll : true,
            loader : new Tree.TreeLoader({
                  dataUrl : 'initialize.action'
             })
});

var root = new Ext.tree.AsyncTreeNode({
text:'ASK123',
draggable : false,
        id:'0000'
});

tree.setRootNode(root);

      tree.render();       root.expand();
});
</script>
</head>
<body>
<div id="tree-div"
style="overflow:auto; height:600px;width:250px;border:1px solid #c3daf9;"></div>
</body>
</html>
应该可以传action的呀
var TreeTest = function(){
    // shorthand
    alert("treetest");
    var Tree = Ext.tree;
        return {
        init : function(){
            // yui-ext tree
          var tree = new Tree.TreePanel({
                el:'tree',
                animate:true,
                autoScroll:true,
                loader: new Tree.TreeLoader({dataUrl:'group.do?action=getAllNodes'}),
                enableDD:true,
                containerScroll: true,
                rootVisible:false,
                dropConfig: {appendOnly:true}
            });
这是我直接执行action得到的，看不出有什么不对啊

问题解决了
现在我点开节点异步加载的时候
    tree.on('beforeload', function(node){
                   alert("=================");
            tree.loader.dataUrl = 'initialize.action';
        });怎么没到action里面去啊但是这个方法执行了
你可以输出下js中的错误信息,或许是找不到路径呢,估计是404错误
我用的是Jquery,其中ajax输出错误信息是error:function(aa){aa.responseText}
你用的是ext,应该也有错误信息吧
