Question

我正在尝试让jstree仅返回我正在重命名的节点的文本。相反，它返回当前节点的名称以及所有子节点的连接列表。我已经将jstree配置为按需加载。我该怎么做才能将contextmenu返回的文本限制为仅重命名为我正在尝试重命名的节点？非常感激！这是完整的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
        $.ajax({
            type: "POST",
            url: '@Url.Content("~/RMS/insertRequirementNode")',
            data: {
                    ParentID : ParentNode,
                    ChildNodeText : data.rslt.obj.text()
            },
            success: function(new_data) {
                $.jstree._reference($("#RequirementsTree")).refresh(-1);
                ParentNode = null;
                data = null;
                return new_data;
            }   
        });

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

        BranchReqFLag = null;
    }).bind("rename.jstree", function(e, data) {
            $.ajax({
                type: "POST",
                url: '@Url.Content("~/RMS/updateRMSHierarchyNode")',
                data: {
                    NodeID: ParentNode,
                    NodeText: data.rslt.obj.text()
                },
                success: function() {
                    ParentNode = null;
                    data = null;
                }

data.rslt.new_name包含输入的新名称。如果您使用Chrome或Firebugs来检查data，您将找到大多数此类问题的答案。

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