Answer 2

我用的是 4.2.0 没有   new ext.tree.treenode这个东西了，
这个事3版本及以前版本的。你知道 怎么在4版本下声明treenode吗

Answer 3

var root = {
    title: '系统',
    expanded: true,
    children:[]
};
for(var i=0;i<object.length;i++){
    root.children.push({                                             //
        id=object[i].id,
        name=object[i].name,
        shouname=object[i].shouname,
        parentid=object[i].parentid,
        leaf: true
    });
    tree.setRootNode(root);                                          //tree为你要操作的树
}
大概思路就是把root设定好 然后替换根节点
