I have an array with some data like this :
const
data = [
{"key":9054,"title":"1","children":[
{"key":8959,"title":"1-0","idFather":8959,"tableIsFamily":false,"children":[]},
{"key":8943,"title":"1-1","idFather":8943,"tableIsFamily":false,"children":[]},
{"key":9021,"title":"1-2","idFather":9021,"tableIsFamily":false,"children":[]},
{"key":8969,"title":"1-3","idFather":8969,"tableIsFamily":false,"children":[]}]},
{"key":9040,"title":"2","children":[
{"key":8957,"title":"2-0","idFather":8957,"tableIsFamily":false,"children":[]},
{"key":8941,"title":"2-1","idFather":8941,"tableIsFamily":false,"children":[
{"key":8947,"title":"2-1-0","idFather":8941},
{"key":9855,"title":"2-1-1","idFather":8941}
]},
{"key":8949,"title":"3-0","idFather":8949,"tableIsFamily":false,"children":[]},
{"key":8983,"title":"3-1","idFather":8983,"tableIsFamily":false,"children":[]},
{"key":10070,"title":"3-2","idFather":10070,"tableIsFamily":false,"children":[]}
]}
];And I have another array with some Id's like this :
[9054, 9021, 9040, 8941, 8947]I want to filter the data array and get only matched array with the second array, I have tried some map/filter but it seem to be more difficult thann i think, Have you any ideas how to deal with this array please ?
The expected output should be :
const
data = [
{"key":9054,"title":"1","children":[
{"key":9021,"title":"1-2","idFather":9021,"tableIsFamily":false,"children":[]},
{"key":9040,"title":"2","children":[
{"key":8941,"title":"2-1","idFather":8941,"tableIsFamily":false,"children":[
{"key":8947,"title":"2-1-0","idFather":8941},
]},
]}
];Thank you!
You can use rectursive function for deep datas. Like this. This function can also be used for deeper structures.
