I have this array with two object, and I have another array with these IDs: [9054,9021,9040,8941,8947]. I want to filter the big array and get a new array with only matched IDs on the second array.
The problem is to get the same configuration of the array, I want just to delete the unmatched IDs. Any idea how to solve it?
const data =
[ { key: 9054, title: '22', children:
[ { key: 8959, title: 'ABR_ADRESSE', idFather: 8959, tableIsFamily: false, children: [] }
, { key: 8943, title: 'ABR_CONTACT', idFather: 8943, tableIsFamily: false, children: [] }
, { key: 9021, title: 'ABR_POSTE', idFather: 9021, tableIsFamily: false, children: [] }
, { key: 8969, title: 'ABR_SOCIETE', idFather: 8969, tableIsFamily: false, children: [] }
] }
, { key: 9040, title: '33', children:
[ { key: 8957, title: 'THB_Adresse_Famille', idFather: 8957, tableIsFamily: false, children: [] }
, { key: 8941, title: 'THB_Contact_Famille', idFather: 8941, tableIsFamily: false, children:
[ { key: 8947, title: 'THB_Contact_Table', idFather: 8941 }
, { key: 9855, title: 'THB_Contact_Table_BIS', idFather: 8941 }
] }
, { key: 8949, title: 'THB_Societe_Famille', idFather: 8949, tableIsFamily: false, children: [] }
, { key: 8983, title: 'THB_TELEPHONE', idFather: 8983, tableIsFamily: false, children: [] }
, { key: 10070, title: 'THB_TEST_5708', idFather: 10070, tableIsFamily: false, children: [] }
] } ]
The expected Output should be :
const data =
[ { key: 9054, title: '22', children:
[
, { key: 9021, title: 'ABR_POSTE', idFather: 9021, tableIsFamily: false, children: [] }
] }
, { key: 9040, title: '33', children:
[
, { key: 8941, title: 'THB_Contact_Famille', idFather: 8941, tableIsFamily: false, children:
[ { key: 8947, title: 'THB_Contact_Table', idFather: 8941 }
] }
] } ] Is this your expected output?
[
{"key": 9054,"title": "22","children": [
{"key": 9021,"title": "ABR_POSTE","idFather": 9021,"tableIsFamily": false,"children": []}
]},
{"key": 9040,"title": "33","children": [
{"key": 8941,"title": "THB_Contact_Famille","idFather": 8941,"tableIsFamily": false,"children": [
{"key": 8947,"title": "THB_Contact_Table","idFather": 8941}
]}
]}
]
You will need to loop over each child and recursively filter the children and check if the sub-child key exists within the keys array.
const
data = [
{"key":9054,"title":"22","children":[
