JSTree's data.rslt.obj.text(）返回一个文本数组，而不是所需节点的文本

我试图让jstree只返回我正在重命名的节点的文本。相反，它返回当前节点以及所有子节点的名称的串联列表。我已经将jstree配置为按需加载。我该怎么做才能将上下文菜单返回的用于重命名的文本限制为仅限于我试图重命名的节点？非常感谢！以下是完整的jstree代码：

        $("#RequirementsTree")
    .bind("select_node.jstree", function(event, data) {
            if(is_requirement_node(data))
            {
                var id = data.rslt.obj.attr("id");
                if(id != null)
                {
                    $("#RequirementsTree").jstree('close_all')
                }
                else {
                    alert("Requirement node select error");
                }
            }
     })
    .bind("create.jstree", function(e, data) {
        // Ajax call to Server with parent node id and new node text

        ParentNode = null;
        if (data.rslt.parent == -1) {
            alert("Can not create new root directory");
            // Rollback/delete the newly created node
            $.jstree.rollback(data.rlbk);
