从TreeGrid控制平面数据输出复杂的嵌套JSON

Question

我正在使用DHTMLX的TreeGrid JavaScript控件来允许用户输入和排列嵌套数据。该控件只允许通过平行访问TreeGrid中的数据（你认为在这个时代它会做JSON ......）。这些行包含rowId，rowIndex，parentId，hasChildren，当然还有数据本身。

数据输入如下：

Data input control

我需要输出（稍后从Mongo读回来）嵌套的JSON，如下所示。

我已经尝试过迭代和递归。我更喜欢递归地执行它，但是我正忙着向积累JSON的对象添加新节点，因为属性名称在整个数据结构中重复，使得obj [key] =（这里是recurse）看似不可能。我需要保留订单。这可能很简单，我错过了一些东西。任何帮助将不胜感激。
