Question

[{text: '广州三号公司', cls: 'folder',iconCls: 'icon-company',expanded: false,children: [{text: '正式车辆（7辆）',cls: 'folder',expanded: false,children:[{text: 'MY0001（行驶）',id:'MY0001', leaf: true,checked: false},{text: 'MY0002（行驶）',id:'MY0002', leaf: true,checked: false},{text: 'MY0004（行驶）',id:'MY0004', leaf: true,checked: false},{text: 'MY0008（行驶）',id:'MY0008', leaf: true,checked: false},{text: 'MY0009（行驶）',id:'MY0009', leaf: true,checked: false},{text: 'MY0011（行驶）',id:'MY0011', leaf: true,checked: false},{text: 'MY0013（行驶）',id:'MY0013', leaf: true,checked: false}]}]}];

Answer 1

所有的键也要套""
比如
'text': '广州三号公司'

Answer 2

如果你是用了json插件去转换这些数据的话，你应该把key和value都用双引号括起来。

Answer 3

JSON没其他任何问题了
引号也确实是问题
我要看你代码了 哈哈~

Answer 4

   public void vehicleTree(){
   response.setContentType("text/html; charset=UTF-8");
try {
 String queryString="select new com.ym.gps.vo.VehicleInfoTreeForm(v.vehicleNo,c.fullName)  from VehicleInfo v,CompanyInfo c where v.vehicleCompanyID=c.id and c.id=3";
     List<VehicleInfoTreeForm> list =  (List<VehicleInfoTreeForm>) vehicleInfoManager.findListByQueryString(queryString);
PrintWriter out =  response.getWriter();
String str = "[{text: '"+list.get(0).getText()+"',id:'001',cls: 'folder',iconCls: 'icon-company',expanded: false,children:[{text: '正式车辆（"+list.size()+"辆）',cls: 'folder',expanded: false,children:[";
for(VehicleInfoTreeForm vehicleInfo :list){
str += "{text: '<span style=color: green;>"+vehicleInfo.getId()+"（行驶）</span>',id:'"+vehicleInfo.getId()+"', leaf: true,checked: false},";

}
str = str.substring(0,str.length()-1);
str += "]}]}];";

out.print(str);
}catch (Exception e) {
e.printStackTrace();
  }
   
   }

Answer 5

另外,我直接写死加载的树的代码是可以出来的..
var carTreeData = [{
    text: '明业运输有限公司（5辆）',
    cls: 'folder',
    iconCls: 'icon-company',
    children: [{
        text: '测试车辆（5辆）',
        cls: 'folder',
        children: [{
            text: '<span style="color: green;">MY0001（行驶）</span>',
            id:'MY0001',
            leaf: true,
            checked: false
        },{
            text: '<span style="color: red;">MY0002（熄火）</span>',
            id:'MY0002',
            leaf: true,
            checked: false
        },{
            text: '<span style="color: green;">MY0003（行驶）</span>',
            id:'MY0003',
            leaf: true,
            checked: false
        },{
            text: '<span style="color: yellow;">MY0004（停车）</span>',
            id:'MY0004',
            leaf: true,
            checked: false
        },{
            text: '<span style="color: green;">MY0005（行驶）</span>',
            id:'MY0005',
            leaf: true,
            checked: false
        },{
            text: '<span style="color: yellow;">MY0006（停车）</span>',
            id:'MY0006',
            leaf: true,
            checked: false
        }]
    },{
     text: '别的分类（0辆）',
     leaf: true
    }]
}];

Answer 6

前台很简单var comtree = new Ext.tree.TreePanel({
    frame:true,
    layout :'fit',
    width : 300,
height: 200,
    animate:false,
    rootVisible:false,
    enableDD:true,
    containerScroll: true,
    loader: new Ext.tree.TreeLoader({
        dataUrl:'vehicleInfo!vehicleTree.action'
    })
});

Answer 7

encodeURI('vehicleInfo!vehicleTree.action')
试试

Answer 9

看你的json 格式是对的。
你最好自己调试一下，看看问题究竟出在哪？
firefox 用firebug 调试
ie 下，vs支持js 调试的我估计是loader: new Ext.tree.TreeLoader({
  dataUrl:'vehicleInfo!vehicleTree.action'
  })这个可能有问题，new Ext.tree.TreeLoader 是一个函数，接受一个js对象，你服务器返回的是json 格式的字符串！还有，你调试一下，看看服务器返回的json 字符串是否正确。 用eval 把json 字符串转成js 对象！
看你的json 字符串后面有一个“；”号。这样转换时会出错！
