ReactJs: Filtering nested objects - javascript

How do I filter nested objects in React? Currently my function is only looking for the main title, not the nested ones.
export const treeData = [
{
title: 'Orange',
key: '0-0',
children: [
{
title: 'Anu',
key: '0-0-0',
isLeaf: true,
},
{
title: 'Anurag',
key: '0-0-1',
isLeaf: true,
},
],
},
{
title: 'ABC',
key: '0-1',
children: [
{
title: 'leaf 1-0',
key: '0-1-0',
isLeaf: true,
},
{
title: 'leaf 1-1',
key: '0-1-1',
isLeaf: true,
},
],
},
]
export default {
treeData,
}
and the function is:
const filtered = treeData.filter((data) => {
return data.title.toLowerCase().includes(e.target.value.toLowerCase())
})
So currently it is only searching the Orange and ABC, not the titles from children.

I recommend flattening the title values and then filtering. Note, the end result will contain a mixture of top level "parent" data and children.
const flattened = treeData.reduce((acc, data) => {
acc.push(data, ...data.children)
return acc;
}, []);
const filtered = flattened.filter((data) => {
return data.title.toLowerCase().includes(e.target.value.toLowerCase())
})
If you only need a filtered list of top level data, you will need to do something like the following:
function dataIncludesTitle(data, title) {
return data.title.toLowerCase().includes(title);
}
const searchValue = e.target.value.toLowerCase();
const filtered = treeData.filter((data) => {
return dataIncludesTitle(data, searchValue) || data.children.some(child => dataIncludesTitle(child, searchValue));
})

Something like:
const filtered = treeData.filter((data) => {
return data.title.toLowerCase().includes(e.target.value.toLowerCase()) ||
data.children.filter(x => x.title.toLowerCase().includes(e.target.value.toLowerCase())).length > 0
})
Look into data.children filtering subobject's title that contains e.target.value.toLowerCase().

If you want to get full objects containing child objects with a title similar to the search string, try this:
const treeData = [
{
title: 'Orange',
key: '0-0',
children: [
{
title: 'Anu',
key: '0-0-0',
isLeaf: true,
},
{
title: 'Anurag',
key: '0-0-1',
isLeaf: true,
},
],
},
{
title: 'ABC',
key: '0-1',
children: [
{
title: 'leaf 1-0',
key: '0-1-0',
isLeaf: true,
},
{
title: 'leaf 1-1',
key: '0-1-1',
isLeaf: true,
},
],
},
];
const searchString = 'ANUR';
const filtered = treeData.filter((datum) => {
const filteredChilds = datum.children.filter((child) => child.title.toLowerCase().includes(searchString.toLowerCase()));
return filteredChilds.length > 0;
});
console.log(filtered);
If you want to get these objects and only matched child objects try this:
const treeData = [{
title: 'Orange',
key: '0-0',
children: [{
title: 'Anu',
key: '0-0-0',
isLeaf: true,
},
{
title: 'Anurag',
key: '0-0-1',
isLeaf: true,
},
],
},
{
title: 'ABC',
key: '0-1',
children: [{
title: 'leaf 1-0',
key: '0-1-0',
isLeaf: true,
},
{
title: 'leaf 1-1',
key: '0-1-1',
isLeaf: true,
},
],
},
];
const searchString = 'ANUR';
const filtered = treeData.map((datum) => {
const filteredChilds = datum.children.filter((child) => child.title.toLowerCase().includes(searchString.toLowerCase()));
return {
...datum,
children: filteredChilds
};
}).filter(datum => datum.children.length > 0);
console.log(filtered);
If you want to get only matched child objects try this:
const treeData = [{
title: 'Orange',
key: '0-0',
children: [{
title: 'Anu',
key: '0-0-0',
isLeaf: true,
},
{
title: 'Anurag',
key: '0-0-1',
isLeaf: true,
},
],
},
{
title: 'ABC',
key: '0-1',
children: [{
title: 'leaf 1-0',
key: '0-1-0',
isLeaf: true,
},
{
title: 'leaf 1-1',
key: '0-1-1',
isLeaf: true,
},
],
},
];
const searchString = 'ANUR';
const filtered = treeData.reduce((acc, datum) => acc.concat(datum.children.filter((child) => child.title.toLowerCase().includes(searchString.toLowerCase()))), []);
console.log(filtered);

Convert nested JSON Object into a specific array format

I have nested JSON object looking like below and this JSON object I have to convert into some particular format which I have given below:
let jsonObj ={"data": {
"cardShop": {
"cardData": {
"cardTitle": "The Platinum Card<sup>®</sup>",
"cardType": "credit-cards",
"dtmProductName": "PlatinumCard",
"viewAllCards": {
"url": "credit-cards/all-cards",
"text": "All Cards"
}
},
"eligibilityChecker": {
"header": "Check your eligibility",
"subHeader": "The Platinum Card®",
"bulletPoints": [
"Only takes a couple of minutes to complete",
"Will not impact your credit rating",
"Allows you to apply with confidence"
]
}
}
}
}
And the above JSON object I have to convert it to the below format with some new properties like key, title, parentId, id, etc..
[
{
id: "cardShop",
key: "cardShop",
title: "cardShop",
selectable: false,
children: [
{
id: "cardData",
path:"cardShopCardData"
key: "cardData",
title: "cardData",
parentId: "cardShop",
selectable: false,
children: [
{
id: "cardTitle",
path :"cardShopcardDatacardTitle"
key: "cardTitle",
title: "cardTitle",
parentId: "cardData",
isLeaf: true,
children: []
},
{
id: "cardType",
key: "cardType",
title: "cardType",
parentId: "cardData",
isLeaf: true,
children: []
},
{
id: "dtmProductName",
key: "dtmProductName",
title: "dtmProductName",
parentId: "cardData",
isLeaf: true,
children: []
},
{
id: "viewAllCards",
key: "viewAllCards",
title: "viewAllCards",
parentId: "cardData",
selectable: false,
children: [
{
id: "url",
key: "url",
title: "url",
parentId: "viewAllCards",
isLeaf: true,
},
{
id: "text",
key: "text",
title: "text",
parentId: "viewAllCards",
isLeaf: true,
}
]
}
]
},
{
id: "eligibilityChecker",
key: "eligibilityChecker",
title: "eligibilityChecker",
parentId: "cardData",
selectable: false,
children: [
{
id: "header",
key: "header",
title: "header",
parentId: "eligibilityChecker",
},
{
id: "subHeader",
key: "subHeader",
title: "subHeader",
parentId: "eligibilityChecker",
},
{
id: "bulletPoints",
key: "bulletPoints",
title: "bulletPoints",
parentId: "eligibilityChecker",
},
{
id: "image",
key: "image",
title: "image",
parentId: "eligibilityChecker",
}
]
}
]
}
];
I have tried below things. For each object I need a parentId.
let prevKey =""
const iterate = (obj) => {
Object.keys(obj).forEach(key => {
if (typeof obj[key] === 'object' && obj[key] !== null) {
let c ={
id:key,
title:key,
selelected:false,
children:[]
};
if(prevKey && Object.keys(output).length === 0){
output ={
children :[]
}
output.children.push(c)
}
else if(prevKey ){
output.children.push(c)
} else{
output = c
}
prevKey = key;
iterate(obj[key])
}
else{
let c ={
id:key,
title:key,
selelected:false,
children:[]
};
output.children[0].children.push(c)
}
})
}
I have tried using recursion but somehow I am not able to get an expected output.
you can do something like this
const transform = data => {
const loop = (data, parent) => Object.entries(data).map(([key, value]) => {
let additional = parent? {
parentId: parent
}:{}
if(typeof value === 'object' && !Array.isArray(value)){
additional = {
...additional,
selectable: false,
children: loop(value, key)
}
}else{
additional.isLeaf = true
}
return {
id: key,
key,
title: key,
...additional
}
})
return loop(data)
}
let jsonObj = {
"data": {
"cardShop": {
"cardData": {
"cardTitle": "The Platinum Card<sup>®</sup>",
"cardType": "credit-cards",
"dtmProductName": "PlatinumCard",
"viewAllCards": {
"url": "credit-cards/all-cards",
"text": "All Cards"
}
},
"eligibilityChecker": {
"header": "Check your eligibility",
"subHeader": "The Platinum Card®",
"bulletPoints": [
"Only takes a couple of minutes to complete",
"Will not impact your credit rating",
"Allows you to apply with confidence"
]
}
}
}
}
console.log(transform(jsonObj.data))

How to remove ids from array

I am trying through the array and use a Array.prototype.filter() method on every children array to find the elements whose key matches with the ones specified.
Then, I'am using Array.prototype.splice() to remove the results from the respective children array but the result is return undefined.
const inputArray = [
"Oxygen-a3b8be32-c36e-a02e-37f4-a35239e0cedb",

children: [{
title: "Black",

},
{
title: "White",

console.log(
"🚀 ~ file: TranferTree.misc.js:152 ~ onCheck ~ outputArray",
originalArray.forEach(e => {
e.children.forEach((c, i) => {

e.children.splice(i, 1);
} else {
c.children.forEach((cc, j) => {
if (inputArray.includes(cc.key)) {
c.children.splice(j, 1);

Note: For example in the Elements => 5e69dbd7-5fee-67a9-c73f-4656f9b90715 children Non metals => 633ac872e78fa7ebee03b8bf i am only remove object with this key => Oxygen-a3b8be32-c36e-a02e-37f4-a35239e0cedb I want to keep the other objects that were not found this also applies to for example Composition => 63b3d5cd12c06ba7ce353f76 or Planets => 33a3182b-93a4-84b9-4c49-c955a8416197.
Since you want to preserve the original object references it will be slightly less efficient, but here's a way you can do it with recursive function calls. It provides the same output as your code, but it's correctly logging the final structure whereas yours is logging the return value of .forEach() which is undefined, by design.

You need to iterate from the end of the array, because splice changes index for the followind item.

How would I get an array of all values throughout all nests of this obj by the key of id.
For example
input: ["0-0-0"]
i wanna output like this
output: ["0-0-0", "0-0-0-0", "0-0-0-1", "0-0-0-2"]
enter image description here
You can recursively loop over all the children and get the keys that either match one of the target keys or if any of their ancestors have matched one the target keys.
const data = [
{
title: "0-0",
key: "0-0",
children: [
{
title: "0-0-0",
key: "0-0-0",
children: [
{ title: "0-0-0-0", key: "0-0-0-0" },
{ title: "0-0-0-1", key: "0-0-0-1" },
{ title: "0-0-0-2", key: "0-0-0-2" },
],
},
{
title: "0-0-1",
key: "0-0-1",
children: [
{ title: "0-0-1-0", key: "0-0-1-0" },
{ title: "0-0-1-1", key: "0-0-1-1" },
{ title: "0-0-1-2", key: "0-0-1-2" },
],
},
{
title: "0-0-2",
key: "0-0-2",
},
],
},
{
title: "0-1",
key: "0-1",
children: [
{ title: "0-1-0-0", key: "0-1-0-0" },
{ title: "0-1-0-1", key: "0-1-0-1" },
{ title: "0-1-0-2", key: "0-1-0-2" },
],
},
{
title: "0-2",
key: "0-2",
},
];
function getKeys(data, targetKeys) {
const targetKeysSet = new Set(targetKeys);
const outputKeys = [];
function getKeysHelper(data, hasParentMatched = false) {
data?.forEach((d) => {
if (targetKeysSet.has(d.key) || hasParentMatched) {
outputKeys.push(d.key);
getKeysHelper(d.children, true);
} else {
getKeysHelper(d.children);
}
});
}
getKeysHelper(data);
return outputKeys;
}
getKeys(data, ["0-0-0"]);
Relevant documentations:
Optional chaining (?.)
Array.prototype.includes
Set
you can do something like this
const extractKeys = data => {
const loop = (data, res) => {
if(!data.children){
return [...res, data.key]
}
return data.children.flatMap(d => loop(d, [...res, data.key]))
}
return [...new Set(loop(data, []))]
}
const findKeys = (data, keys) => data.flatMap(extractKeys).filter(k => keys.some(key => k.includes(key)))

Converting JS object to different order

I have JS object like this one:
const networkTree = [
{
id: 10,
hasChildren: true,
children: [
{
id: 9,
hasChildren: true,
children: [
{
id: 7,
hasChildren: true,
children: [
{
id: 5,
hasChildren: false,
children: [],
},
{
id: 4,
hasChildren: false,
children: [],
},
],
},
{
id: 6,
hasChildren: true,
children: [
{
id: 3,
hasChildren: false,
children: [],
},
{
id: 2,
hasChildren: false,
children: [],
},
],
},
],
},
{
id: 8,
hasChildren: true,
children: [
{
id: 1,
hasChildren: false,
children: [],
},
{
id: 11,
hasChildren: false,
children: [],
},
],
},
],
},
];
I have to convert it with a function takes input js object like above to this order:
const myTreeData = [
{
name: 'Top Level',
children: [
{
name: 'Level 2: A',
},
{
name: 'Level 2: B',
},
],
},
];
I am stucked at this point:
const convertTree = (array) => (
treeDatas[];
treeData[];
for(i = 0 ; i < array.length ; i++) {
treeDatas.push(array[i]);
treeData[i].name.push(array[i].id);
}
);
If input networkTree[0].id is 15, myTreeData[0].name should be 15. I want to use id's as names on converted object. I don't need hasChildren boolean value. I will use converted object format with react-ds3-component. If you need more information about converted object format please check https://www.npmjs.com/package/react-d3-tree
If I understand you correctly you want to rename id to name and remove hasChildren? Then you can use this recursive function.
const convertTree = (tree) =>
tree.map((node) => ({
name: node.id,
children: convertTree(node.children)
}))
It's the same as this function, just less verbal.
const convertTree = (tree) => {
return tree.map((node) => {
return {
name: node.id,
children: convertTree(node.children)
}
})
}

Pruning a tree by mapping nodes of tree that fail a test to its children

My problem here builds upon another problem I was trying to solve and received an excellent answer for where I have a tree:
const treeData = [{
title: '0-0',
key: '0-0',
children: [{
title: '0-0-0',
key: '0-0-0',
children: [
{ title: '0-0-0-0', key: '0-0-0-0', children: [] },
{ title: '0-0-0-1', key: '0-0-0-1', children: [] },
{ title: '0-0-0-2', key: '0-0-0-2', children: [] },
],
}, {
title: '0-0-1',
key: '0-0-1',
children: [
{ title: '0-0-1-0', key: '0-0-1-0', children: [] },
{ title: '0-0-1-1', key: '0-0-1-1', children: [] },
{ title: '0-0-1-2', key: '0-0-1-2', children: [] },
],
}, {
title: '0-0-2',
key: '0-0-2',
children: []
}],
}, {
title: '0-1',
key: '0-1',
children: [
{ title: '0-1-0-0', key: '0-1-0-0', children: [] },
{ title: '0-1-0-1', key: '0-1-0-1', children: [] },
{ title: '0-1-0-2', key: '0-1-0-2', children: [] },
],
}, {
title: '0-2',
key: '0-2',
children: []
}];
and an array of leaf nodes:
const leafNodes = ['0-0-1-2', '0-1-0-1', '0-1-0-2']
Before, I just wanted a filtered/pruned copy of the tree that contains all the paths to the leaf nodes, but now I would like to further prune it by removing the parent node that doesn't satisfy a test -- the test being having all of its children included in the list of leaf nodes. The resulting tree would look like this:
const pruned = [{
title: '0-0-1-2',
key: '0-0-1-2',
children: []
},
{
title: '0-1-0-1',
key: '0-1-0-1',
children: []
}, {
title: '0-1-0-2',
key: '0-1-0-2',
children: []
}
]
Here, the node with keys 0-0-1 would be removed because only one of its 3 child nodes (0-0-1-2) is included in the leafNodes list and the child nodes included in the leaf nodes list (in this case, just the one) are bumped up to the level of their now removed parent. This would flow back up to the parent of the removed node, now with key 0-0, since not all of its children are included in the pruned tree.
This same pattern would apply to 0-1.
You could iterate the array and check if the child are complete selected , then get the actual node or just some children, then take the children only.
function getShort(array, keys) {
var result = [],
every = true;
array.forEach(o => {
var children;
if (keys.includes(o.key)) return result.push(o);
if (!o.children || !o.children.length) return every = false;
children = getShort(o.children, keys);
if (children.length && children.length === o.children.length) return result.push(o);
result.push(...children);
every = false;
});
return every
? array
: result;
}
const
treeData = [{ key: '0-0', children: [{ key: '0-0-0', children: [{ key: '0-0-0-0', children: [] }, { key: '0-0-0-1', children: [] }, { key: '0-0-0-2', children: [] }] }, { key: '0-0-1', children: [{ key: '0-0-1-0', children: [] }, { key: '0-0-1-1', children: [] }, { key: '0-0-1-2', children: [] }] }, { key: '0-0-2', children: [] }] }, { key: '0-1', children: [{ key: '0-1-0-0', children: [] }, { key: '0-1-0-1', children: [] }, { key: '0-1-0-2', children: [] }] }, { key: '0-2', children: [] }],
leafNodes = [
'0-0-0-0', '0-0-0-1', '0-0-0-2', // all 0-0-0 all 0-0
'0-0-1-0', '0-0-1-1', '0-0-1-2', // all 0-0-1 all 0-0
'0-0-2', // all 0-0-2 all 0-0
'0-1-0-1', '0-1-0-2'
],
short = getShort(treeData, leafNodes);
console.log(short);
.as-console-wrapper { max-height: 100% !important; top: 0; }
