问题很简单，希望可以利用id获取到对应的node。这个很多树菜单都实现了接口，但是ext好像没有，难道需要自己写遍历？
修改后代码如下：对遍历函数处理了一下，树菜单显示正常。
function lookupNode(_root,id){
if(_root){
var treeId = _root.attributes['id'];
if(id == treeId){
return _root;
}
var nodes = _root.childNodes;
if(nodes.length==0){
return null;
}
for(var i=0; i<nodes.length; i++){
if(nodes[i]!=null){
var xx = lookupNode(nodes[i],id);
}
}
return xx;
}
}
