I want to get the path to a given node, example if I provide key=8, then the result should be
**"ABC Company/Europe/hhhh" ** ``` Note -Depth of the array is unknown and the key is always unique,
I'm using spring boot as my backend framework.
[
{
"key": 1,
"label": "ABC Company",
"nodes": [
{
"key": 2,
"label": "Asia Pacific",
"nodes": [
{
"key": 3,
"label": "ttt",
"nodes": [],
"isLeaf": false
},
{
"key": 4,
"label": "thhhh",
"nodes": [],
"isLeaf": false
},
{
"key": 5,
"label": "hhhh",
"nodes": [
{
"key": 10,
"label": "test1",
"nodes": [],
"isLeaf": false
},
{
"key": 11,
"label": "test2",
"nodes": [],
"isLeaf": false
},
{
"key": 12,
"label": "test3",
"nodes": [],
"isLeaf": false
}
],
"isLeaf": false
}
],
"isLeaf": false
},
{
"key": 6,
"label": "Europe",
"nodes": [
{
"key": 7,
"label": "fff",
"nodes": [],
"isLeaf": false
},
{
"key": 8,
"label": "hhhh",
"nodes": [],
"isLeaf": false
},
{
"key": 9,
"label": "mmmm",
"nodes": [],
"isLeaf": false
}
],
"isLeaf": false
}
],
"isLeaf": false
}
]
I'm expecting to pass key value example if I pass key=8 then the output should be ABC Company/Europe/hhhh
I have tried these but they return the incorrect path

I have an array :
{
"count": 8,
"id": "accountId",
"name": " Account Id",
"values": [
{
"count": 2,
"id": "1234456789000",

}
And I have a 2nd array :
[
{
"count": 2,
"id": "432112426686",
"name": "432112426686"
},
{
"count": 2,
"id": "1234456789000",
"name": "1234456789000"
}
]
The second array, I have filtered based on some requirement.
I want to replace the values from 1st array with second array.
Using typescript code.
Please help here.
If I understand question, you just need iterate by values array and find same id from second array.
function findAndSwitch(object1, array1): void {
object1.values = object1.values.map(el => {
const objToSwitch = array1.find(eleArr => eleArr.id === el.id);
if (objToSwitch) {
return el = objToSwitch;
} else {
return el;
}
});
}

Let's say your variable names are obj1 and arr2, respectively. First transform arr2 into an object obj2:
let obj2 = arr2.reduce((acc,cur) => ({...acc,[cur.id]:cur}),{});
Which now looks like this:
{
'432112426686': {
count: 20,
id: '432112426686',
name: '432112426686'
},
'1234456789000': {
count: 20,
id: '1234456789000',
name: '1234456789000'
}
}
Then transform obj1 based on obj2 as follows:
obj1.values = obj1.values.map(value => obj2[value.id] || value);
Please note that since the data in arr2 is identical to the corresponding data in obj1, I have altered the values of count property in arr2 in order to demonstrate that obj1 will be updated accordingly.
DEMO ONE
let obj1 = {
"count": 8,
"id": "accountId",
"name": " Account Id",
"values": [
{
"count": 2,
"id": "1234456789000",
"name": "1234456789000"
},
{
"count": 1,
"id": "135792468045",
"name": "135792468045"
},
{
"count": 1,
"id": "309983110022",
"name": "309983110022"
},
{
"count": 2,
"id": "432112426686",
"name": "432112426686"
},
{
"count": 1,
"id": "6ee26149-a156-4665-bd26-a6e46b49a70f",
"name": "6ee26149-a156-4665-bd26-a6e46b49a70f"
},
{
"count": 1,
"id": "927b48ce-efe4-4c20-98f0-ec6c54f59b45",
"name": "927b48ce-efe4-4c20-98f0-ec6c54f59b45"
}
]
};
let arr2 = [
{
"count": 20,
"id": "432112426686",
"name": "432112426686"
},
{
"count": 20,
"id": "1234456789000",
"name": "1234456789000"
}
];
let obj2 = arr2.reduce((acc,cur) => ({...acc,[cur.id]:cur}),{});
obj1.values = obj1.values.map(value => obj2[value.id] || value);
console.log( obj1 );
--
However, if all you want is to replace all the obj1.values with arr2, all you need is:
obj1.values = [...arr2];
And this will give rise to:
{
count: 8,
id: 'accountId',
name: ' Account Id',
values: [{
count: 20,
id: '432112426686',
name: '432112426686'
},
{
count: 20,
id: '1234456789000',
name: '1234456789000'
}
]
}

let obj1 = {
"count": 8,
"id": "accountId",
"name": " Account Id",
"values": [
{

I have an array of object like this :

}
]
and I have another (simple) array like this one for example
["react","prestashop"]
I would like to filter the first array based on STACK key on the value of the second array, i.e. I would like to be returned all elements that have at least one element of the array (variable).
I have come to this
const filter = value => {
const newProj = relProjects.filter(obj =>
obj.stack.some(st => st.title.toLowerCase().includes(value))
)
setProjRel(newProj)
}
console.log(filter(["react","prestashop"])
however in this way I can only get the elements that contain all the elements of the array. Instead I would like to have returned all the elements that have AT LEAST 1 stack of the ones I passedThanks to who will answer me
Using Array#filter and Array#includes
Filter through the data array. With the predicate being that the stack array has at least one item that is included in the matches array
const data = [{"url":"https://recipes-gatsby-react.netlify.app/","stack":[{"id":1,"title":"GatsbyJs"},{"id":2,"title":"React"},{"id":3,"title":"GraphQl"}],"id":"Project_1","featured":false,"title":"Gatsby recipes app"},{"url":"https://resort-react-mr.netlify.app","stack":[{"id":4,"title":"React"},{"id":5,"title":"Contentful"}],"id":"Project_2","featured":false,"title":"react resort"},{"url":"https://color-generator-react-mr.netlify.app/","stack":[{"id":6,"title":"React"}],"id":"Project_3","featured":false,"title":"color generator"},{"url":"","stack":[{"id":7,"title":"React Native"},{"id":8,"title":"Firebase"}],"id":"Project_4","featured":false,"title":"Book-Worm"},{"url":"","stack":[{"id":9,"title":"React Native"},{"id":10,"title":"Firebase"},{"id":11,"title":"Stripe"},{"id":12,"title":"Google Api"}],"id":"Project_5","featured":false,"title":"Delivery App"},{"url":"https://cocktails-react-app-mr.netlify.app/","stack":[{"id":13,"title":"React"}],"id":"Project_6","featured":false,"title":"Cocktails App"},{"url":"https://www.ideacasaitalia.it/index.php","stack":[{"id":14,"title":"Prestashop"}],"id":"Project_7","featured":false,"title":"Idea Casa Italia"}];
const matches = ["react", "prestashop"];
const filtered = data.filter(({ stack }) => stack.filter(({ title }) => matches.includes(title.toLowerCase())).length > 0);
console.log(filtered);
Good morning, can anyone advise me? I'm pretty clueless. I've already spent a few hours on it and I don't know how to solve this.
The data is fictitious and the original JSON is far more complex.

How can I get from main -> content -> items -> images -> url?
More precisely each images and from that url.
Thank you very much in advance for your help.
It looks like your main array has an array as 1st element. If that is correct, you take the first element of main, and then loop over that.
let jsonObj = {
"main": [
[
{
"type": "dasdasdasd",
"id": 5,
"content": {
"title": "adadadsad",
"items": [
{
"date": "2012-02-02T11:23:00Z",
"id": 12,
"name": "test",
"isEnabled": false,
"isHighlited": false,
"images": {
"lists": {
"small": [
{
"id": 18,
"position": 0,
"titleImage": true,
"url": "",
"thumbnailReady": true
}
],
"original": [
{
"id": 19,
"position": 0,
"titleImage": true,
"url": "",
"thumbnailReady": true
}
],
"large": [
{
"id": 22,
"position": 0,
"titleImage": true,
"url": "",
"thumbnailReady": true
}
],
"medium": [
{
"id": 23,
"position": 0,
"titleImage": true,
"url": "",
"thumbnailReady": true
}
]
}
},
"enum": "LINIE",
"url": "https://test.com"
}
]
}
}
]
],
"second": [
]
}
let smallImg = "", originalImg = "", largeImg = "", mediumImg = "";
jsonObj.main[0].forEach(mainItem => {
mainItem.content.items.forEach(item => {
smallImg = item.images.lists.small[0].url;
originalImg = item.images.lists.original[0].url;
largeImg = item.images.lists.large[0].url;
mediumImg = item.images.lists.medium[0].url;
});
});
console.log(smallImg);
console.log(originalImg);
console.log(largeImg);
console.log(mediumImg);
I have users indexed with categories as follows
{
id: 1
name: John
categories: [
{
id: 1
name: Category 1
},
{
id: 2
name: Category 2
}
]
},
{
id: 2
name: Mark
categories: [
{
id: 1
name: Category 1
}
]
}
And I'm trying to get all the documents with Category 1 or Category 2 with
{
filter:
{
bool: {
must: [
{
terms: {user.categories.id: [1, 2]}
}
]
}
}
}
But It only returns the first document that has the two categories, what I am doing wrong?
As I understood, terms search that one of the values is contained in the field, so for user 1
user.categories.id: [1, 2]
user 2
user.categories.id: [1]
Categoy id 1 is contained in both documents
The best way to handle this is probably with a nested filter. You'll have to specify the "nested" type in your mapping, though.
I can set up an index like this:
PUT /test_index
{
"settings": {
"number_of_shards": 1,
"number_of_replicas": 0
},
"mappings": {
"doc": {
"properties": {
"categories": {
"type": "nested",
"properties": {
"id": {
"type": "long"
},
"name": {
"type": "string"
}
}
},
"id": {
"type": "long"
},
"name": {
"type": "string"
}
}
}
}
}
then add some docs:
PUT /test_index/doc/1
{
"id": 1,
"name": "John",
"categories": [
{ "id": 1, "name": "Category 1" },
{ "id": 2, "name": "Category 2" }
]
}
PUT /test_index/doc/2
{
"id": 2,
"name": "Mark",
"categories": [
{ "id": 1, "name": "Category 1" }
]
}
PUT /test_index/doc/3
{
"id": 3,
"name": "Bill",
"categories": [
{ "id": 3, "name": "Category 3" },
{ "id": 4, "name": "Category 4" }
]
}
Now I can use a nested terms filter like this:
POST /test_index/doc/_search
{
"query": {
"constant_score": {
"filter": {
"nested": {
"path": "categories",
"filter": {
"terms": {
"categories.id": [1, 2]
}
}
}
},
"boost": 1.2
}
}
}
...
