Answer 1

 lines:true,//节点之间连接的横竖线  这句去掉

Answer 2

var jsonValue = [{
                    "text": szDomainName,
                    "id": 1001,
                    "leaf": false,
                    "cls": "folder",
                    "children": [{
                        "text": "摄像头",
                        "id": 1000,
                        "leaf": false,
                        "cls": "folder",
                        "children": [{
                            "text": ulResType,
                            "id": szResName,
                            "leaf": true,
                            "cls": "file"
                        }]
                    
                    }]
                }];  这是json

Answer 3

lines:true  这个属性去掉也是一样啊

Answer 4

我和你问题一样,不过我解决了,解决方法这样的你参考一下,   
var M={};
M.TreeLoader = function(){
    M.TreeLoader.superclass.constructor.call(this);
    this.proxy = new Ext.data.ScriptTagProxy({
        url : this.dataUrl
    });
}; Ext.extend(M.TreeLoader, Ext.tree.TreeLoader, {
    dataUrl: 'xshell/html!lookFile.action?'+'url='+global.url+"&mothod=A"+"&param="+global.param+'&encoding='+global.encoding,
    requestData : function(node, cb){
        this.proxy.request('read', null, {}, {
            readRecords : function(o){
                return o;
            }
        }, this.addNodes, this, {node:node, cb:cb});
    },
    addNodes : function(o, arg){
        var node = arg.node;
        for(var i = 0, len = o.length; i < len; i++){
            var n = this.createNode(o[i]);
            if(n){
                node.appendChild(n);
            }
        }
        arg.cb(this, node);
    }
});是Treeloader 的问题

Answer 5

你重写一下Treeloader 基本就解决了,这里面最重要的是用Treeloader.createNode方法,这个方法初始化节点用的,我也是看源码才知道的
