我想在特定区域下的data array中插入detail array。
例如，detail array中bdh键的值应该放在data array的bdh键中，替换开头的空数组。同样，detail array中 hadoop 键的值应替换data array中的hadoop键当前具有的空数组。应针对 details 数组中的每个键进行此替换。
我该如何实现此目的？
数据数组
{"data":
{
"categories":
{
"articles":
{
"bdh":[],
"hadoop":[]
},
"videos":
{
"bdh Videos":[],
"hadoop Videos":[]
}
}
}
}
详细信息数组
{"details":{
"bdh":
[
{"id":1, "name":"bdh article 1", "body":"this is bdh article 1 body."},
{"id":2, "name":"bdh article 2", "body":"this is bdh article 2 body."}
],
"hadoop":
[
{"id":3, "name":"hadoop article 1", "body":"this is hadoop article 1 body."},
{"id":4, "name":"hadoop article 2", "body":"this is hadoop article 2 body."}
],
"bdh Videos":
[
{"id":5, "name":"bdh videos 1", "body":"this is bdh videos 1 body."},
{"id":6, "name":"bdh videos 2", "body":"this is bdh videos 2 body."}
],
"hadoop Videos":
[
{"id":7, "name":"hadoop videos 1", "body":"this is hadoop videos 1 body."},
{"id":8, "name":"hadoop videos 2", "body":"this is hadoop videos 2 body."}
]
}
