console.log(data);
对于每个父级的children属性，我有单独的Ajax调用，它们会返回一个数组。是否可能将这三个数组组合起来，生成一个如fiddle中所示的数组？
以上数据的原始来源是这里，这是从这里获取的
我想要的更多解释：
我手头有3个数组。
"EmployeeID": 2,的数据。"EmployeeID": 8,1,3,4和5，是第一个数组的子项。"EmployeeID": 6,7和9，是第二个数组的子项。我通过Ajax调用获取了以上所有数组（未在上面显示），想知道是否可以以这种方式组合它们，以生成上述格式的数据。
让我困惑的是如何像上面的格式中那样添加children: 。
在这里你可以尝试这个逻辑：
我们可以传递具有嵌套结构的数据，例如：
data->childrenArray->data->childrenArray等等在MakeNestedInLinear(data)中，它将返回单个数组（线性数据）中的扁平结果
