Question

如何用另一个节点替换给定的jsTree节点（https://www.jstree.com/）？那里有几个类似的问题（即https://stackoverflow.com/a/16681669/1032531），但是它们不使用jsTree api（例如create_node），也没有显示如何替换新节点。

我在下面提供了实际用例以及我现有的代码，并且演示位于https://output.jsbin.com/xijehek。

以下树具有一个Add Child节点，单击该节点时应将该节点替换为包含多个子节点的Child节点（在下一步中进行介绍）。

现在，该树具有一个Child节点和几个子节点。单击最后一个“删除子级”子节点时，Child节点及其子节点需要替换为Add Child节点（在上一步中进行了介绍）。
