javascript - jsTree : How to get all nodes from jstree?

Question

如何获取jsTree中的所有节点？

我正在用 xml 构建 jsTree

Root
     -----A
          -----A1
               -----A1.1
               -----A1.2
          -----A2
               -----`A2.1`
               -----A2.2

     -----B
          -----B1
          -----B2

     -----C
          -----C1
               -----C1.1
               -----C2.2

我希望 jsTree 中存在的所有节点 (ID) 的数组如下所示

预期输出:[Root, A, A1, A1.1, A1.2, A2, A2.1, A2.2, B, B1, B2, C, C1, C1.1, C2。 2]

来自 documentation :

.get_json ( node , li_attr , a_attr )

This function returns an array of tree nodes converted back to JSON.

有关相同功能的更多信息来自 this doc :

This function traverses the whole tree and exports it as JSON. Refer do the data sources section to see the format of the output.

If you specify a node as the first argument, only that node and its children are included in the export, otherwise the whole tree is exported.
