dynatree - 使用延迟加载扩展键路径

Question

我有一个包含多个项目和多个级别的完整树，该树是通过 ajax 调用构建的并使用惰性节点

所以现在我想添加该功能，以便我的树可以加载并选择项目，如果我给出完整路径，但在我可以选择项目之前，我需要确保该项目是通过延迟加载加载的，这样我就可以访问它。

我找到了函数 .loadKeypath()，因此为了测试，我使用

检索了节点的完整路径

node.getKeyPath();

所以路径是/12/16/17/18

所以我发现我应该在ajax数据加载之后放置这段代码

onPostInit: function(isReloading, isError){
                $("#tree").dynatree("getTree").loadKeyPath("/12/16/17/18", function(node, status){
                    if(status == "loaded") {
                        // 'node' is a parent that was just traversed.
                        // If we call expand() here, then all nodes will be expanded
                        // as we go
                        node.expand();
                    }else if(status == "ok") {
                        // 'node' is the end node of our path.
                        // If we call activate() or makeVisible() here, then the
                        // whole branch will be exoanded now
                        node.activate();
                    }else if(status == "notfound") {
                        var seg = arguments[2],
                            isEndNode = arguments[3];
                    }
                });
            }

但现在我在控制台中收到此警告:

Node not found: 12 jquery.dynatree.js:49

这是完整的日志

那么我如何加载嵌套在其他节点中的节点

Answer 1

这是一个供将来引用的答案

经过一些调试和 dynatree 开发人员的帮助，我们想出了一个解决方案，如果您想加载关键路径，请使用字符串作为键而不是整数。

而不是

 "icon": false,
        "checkbox": false,
        "title": "xxxxxxxx",
        "key": 23,
        "type": "child"

使用

 "icon": false,
        "checkbox": false,
        "title": "xxxxxxxx",
        "key": "23",
        "type": "child"

这样 loadkeypath 函数就会选择正确的路径!
