struts2 jsonplugin如何产生etxjs tree 的json

如题

[code="java"][{"id":1,"text":"校准计划表","children":[{"id":2,"text":"2011年度","children":[],"pid":1,"leaf":true}],"pid":0,"leaf":false},{"id":3,"text":"校准台账","children":[{"id":4,"text":"aaa队","children":[],"pid":3,"leaf":true}],"pid":0,"leaf":false},{"id":5,"text":"试验检测计划表","children":[{"id":6,"text":"2012","children":[],"pid":5,"leaf":true}],"pid":0,"leaf":false},{"id":7,"text":"试验检测台账","children":[{"id":8,"text":"aaa队","children":[],"pid":7,"leaf":true}],"pid":0,"leaf":false},{"id":9,"text":"加工计划表","children":[{"id":10,"text":"2012年度","children":[],"pid":9,"leaf":true}],"pid":0,"leaf":false},{"id":11,"text":"维修记录","children":[{"id":12,"text":"aaa队","children":[],"pid":11,"leaf":true}],"pid":0,"leaf":false},{"id":13,"text":"系统设置","children":[{"id":14,"text":"用户信息维护","children":[],"pid":13,"leaf":true},{"id":15,"text":"角色信息维护","children":[],"pid":13,"leaf":true}],"pid":0,"leaf":false}]

这个不是你的tree请求回来的数据吗？如果有数据返回，说明请求已经发起了

[code="java"]
直接 json-lib把···struts2 jsonplugin生成的json少了[]，extjs tree需要[]的啊·

[/code]

[code="java"]json数据已经传到前台么？ 用firebug看看··[/code]

改下配置
[code="java"]
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">








[/code]

[code="java"]
}, {
"id" : 15 //这里的逗号呢 ？？怎么没有呢？？ 数据有问题吧
"text" : "角色信息维护",
"children" : [],
"pid" : 13,
"leaf" : true
}],
"pid" : 0,
"leaf" : false
}]

[/code]

晕啊
var Tree = Ext.tree;
这样定义的啊···你大小写写错了···

[code="java"]
Ext.onReady(function() {
var Tree= Ext.tree;
var tree = new Tree.TreePanel({
el:'tree-div',
autoScroll:true,
animate:true,
enableDD:true,
containerScroll: true,
loader: new Tree.TreeLoader({
dataUrl:'rightAction.action'
})
});

var root =new Tree.AsyncTreeNode({
    text:"可用权限列表",
    draggable:false,
    id:'0'
});


tree.setRootNode(root);
tree.render();
root.expand();

});

这样才对····
[/code]

[code="java"]
var tree = Ext.tree;
var tree= new Tree.TreePanel({
[/code]
你把命名空间赋值给tree，这里应该是“Tree”，不知道是你把代码贴上来写错了呢，还是本身就写错了。

还有你[code="java"]el:'tree-div',[/code]是不是写错了，“el”属性从文档上看，它是只读的，应该是[code="java"]renderTo: 'tree-div',[/code]
