我想在我的个人页面上显示我的书签列表。
由于文件夹很大且组织得很好,我希望有一个 TreeView ,用户可以在其中(打开)折叠文件夹,就像使用文件浏览器(如许多浏览器中的书签管理器)一样。
我找到了 http://mbraak.github.io/jqTree/ , https://github.com/chenglou/react-treeview , https://github.com/pqx/react-ui-tree和 https://github.com/alexcurtis/react-treebeard ,但我更喜欢不需要安装 jQuery 或 React 的非常轻便的东西(我可以自己编写代码)(我只想显示一棵树,没有拖放或高级功能,只是扩展和导航箭头。
我还找到了https://github.com/resnyanskiy/js.tree和 https://github.com/justinchmura/js-treeview ,但它们不支持箭头导航。
也许我可以获得 chromium 书签管理器的 TreeView 代码?
你知道任何图书馆吗?或者你能给我解释一下最简单的编程方法吗?
