Get all its parent nodes path for each child nodes

Hi I have below code running, but I would like to add one more property called path which should consist all its parent node path
Expected output I need something as I have shown for cardTtile, so I need same for each node.
[
{
"id": "cardShop",
"key": "cardShop",
"title": "cardShop",
"selectable": false,
"path":cardShop"
"children": [
{
"id": "cardData",
"key": "cardData",
"title": "cardData",
"parentId": "cardShop",
"path":cardShop.cardData"
"selectable": false,
"children": [
{
"id": "cardTitle",
"key": "cardTitle",
"title": "cardTitle",
"parentId": "cardData",
"path":cardShop.cardData.cardTitle"
"isLeaf": true
},
{
"id": "cardType",
"key": "cardType",
"title": "cardType",
"parentId": "cardData",
"isLeaf": true
},
{
"id": "dtmProductName",
"key": "dtmProductName",
"title": "dtmProductName",
"parentId": "cardData",
"isLeaf": true
},
{
"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": "cardShop",
"selectable": false,
"children": [
{
"id": "header",
"key": "header",
"title": "header",
"parentId": "eligibilityChecker",
"isLeaf": true
},
{
"id": "subHeader",
"key": "subHeader",
"title": "subHeader",
"parentId": "eligibilityChecker",
"isLeaf": true
},
{
"id": "bulletPoints",
"key": "bulletPoints",
"title": "bulletPoints",
"parentId": "eligibilityChecker",
"isLeaf": true
}
]
}
]
}
]
I have below running code example here. I tried to persist parentKey recursively but its not giving me expected output.
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))
]
You suggestion would be appreciated
Thanks

You could take another variable for path and add the actual key to it.
const transform = data => {
const loop = (data, parentId, previousPath = '') => Object
.entries(data)
.map(([key, value]) => {
const
additional = parentId ? { parentId } : {},
path = previousPath + (previousPath && '.') + key;
Object.assign(
additional,
value && typeof value === 'object' && !Array.isArray(value)
? { selectable: false, children: loop(value, key, path) }
: { isLeaf: true }
);
return { id: key, key, title: key, path, ...additional };
});
return loop(data);
}
const 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(data));

How to Update value nested array in array jquery

Please help
I tried to edit the second myArray, and in myArray there is myArray[data] which is also an array, how do I update it??

how to change myArray second data record?
this is my code for change update, but there all data is updated, how to change only myArray third data inside myArray[data] ??
//this is my code for update
var update_array = 2;
var update_inside_array = 0;
var valnya = '12';
var arr_data_edit = myArray[update_array].data;
if(arr_data_edit[update_inside_array].id == update_inside_array){
arr_data_edit[idfiledx].record = valnya;
}
console.log(myArray);
I've tried various ways, this is the last one I ran out of ideas, please help to solve this
Thank you for the help

Your current code should work if you simply change idfiledx to update_inside_array:
var update_array = 2;
var update_inside_array = 0;
var valnya = '12';
var arr_data_edit = myArray[update_array].data;
if(arr_data_edit[update_inside_array].id == update_inside_array){
arr_data_edit[update_inside_array].record = valnya;
}
console.log(myArray);
In general, I think it would probably be better to find the item to be updated (the one that has `id: 2`) regardless of its position in the array.
Here's a way to doing that using the .find method of arrays:
const
myArray = [
{ "id": 0, "item": "DONOMULYO", "data": [
{ "id": 0, "field": "satu", "record": "11" },
{ "id": 1, "field": "dua", "record": "" }
]},
{ "id": 1, "item": "PAGAK", "data": [
{ "id": 0, "field": "satu", "record": "11" },
{ "id": 1, "field": "dua", "record": "" }
]},
{ "id": 2, "item": "BANTUR", "data": [
{ "id": 0, "field": "satu", "record": "11" },
{ "id": 1, "field": "dua", "record": "" }
]},
{ "id": 3, "item": "SUMBERMANJING WETAN", "data": [
{ "id": 0, "field": "satu", "record": "11" },
{ "id": 1, "field": "dua", "record": "" }
]}
],
outerId = 2,
innerId = 0,
newVal = '12',
outerObj = myArray.find(obj => obj.id == outerId),
innerObj = outerObj.data.find(obj => obj.id == innerId);
innerObj.record = newVal;
console.log(myArray);
.as-console-wrapper{min-height: 100%!important; top: 0}
(Btw, it doesn't look like you use or need any jQuery for this.)

You don't need jQuery, you can use either find or filter, here is an example using filter:
var update_array = 2;
var update_inside_array = 0;
var valnya = '12';
var item = myArray[update_array].data.filter(x => x.id == update_inside_array)[0];
if (typeof item !== 'undefined') item.record = valnya;
console.log(myArray);

How to replace an array of objects with an array including newer objects in TypeScript?

For example: I have an array of objects like this:
let arrayOfObjects: [
{ "id": 0, "name": "Available" },
{ "id": 1, "name": "Ready" },
{ "id": 2, "name": "Started" }
];
Now I want to replace or overwrite the array above with the same array, but including different values (same keys, different values):
let arrayOfObjects: [
{ "id": 0, "name": "Not Available" },
{ "id": 1, "name": "Not Ready" },
{ "id": 2, "name": "Not Started" }
];
How can this be done in TypeScript?

Try this JS
let oneArray = [
{ "id": 0, "name": "Available" },
{ "id": 1, "name": "Ready" },
{ "id": 2, "name": "Started" }
];
let twoArray = [
{ "id": 0, "name": "Not Available" },
{ "id": 1, "name": "Not Ready" },
{ "id": 2, "name": "Not Started" }
];
let newArray = Object.assign([], oneArray, twoArray);
console.log(newArray);
In TS
interface Data {
oneArray: array;
twoArray: array;
}
function merge(data: Data) {
return Object.assign([], data.oneArray, data.twoArray);
}
let user = {
oneArray: [
{ "id": 0, "name": "Available" },
{ "id": 1, "name": "Ready" },
{ "id": 2, "name": "Started" }
],
twoArray: [
{ "id": 0, "name": "Not Available" },
{ "id": 1, "name": "Not Ready" },
{ "id": 2, "name": "Not Started" }
]
};
console.log(merge(user));

Sure :)
let arrayOfObjects = [
{ "id": 0, "name": "Available" },
{ "id": 1, "name": "Ready" },
{ "id": 2, "name": "Started" }
];
const newValues = ['Not Available', 'Not Ready', 'Not Started'];
newValues.forEach((value, i) => {
arrayOfObjects.find(o => o.id === i).name = value;
});
console.log(arrayOfObjects);
I wouldn't recommend this though: functional programming is awesome.

let arrayOfObjects = [
{ "id": 0, "name": "Available" },
{ "id": 1, "name": "Ready" },
{ "id": 2, "name": "Started" }
];
let names = ['Not Available', 'Not Ready', 'Not Started']
let result = arrayOfObjects.map((user, index) => ({ ...user, name: names[index] }))
console.log(result)

Search a Javascript Object for the position of a specific ID? [duplicate]

This question already has answers here:
Find by key deep in a nested array
(21 answers)
Closed 4 years ago.
I have a Javascript object with lots of different sections. How can I search through all of the sections to find the position of a specific ID? The ID's that I am searching for are not in a specific location, and can be located in any of the tree branches.
For example, I am searching for this ID:
xobmnbjxg0g_1527269346261
And I am trying to output the position of that ID, which would be this:
app['structure'][0]['if-children'][0]['id']

Interesting puzzle/question.
pretty sure there are some edge cases im missing but this seems to pass some tests.
function is(obj, type){
return Object.prototype.toString.call(obj) === `[object ${type}]`;
}
function findPosition(obj, mykey, myval, res){
if(is(obj, "Object")){
if(mykey in obj && obj[mykey] === myval){
res.tree.push(mykey);
res.found = true;
} else {
for( let key in obj){
if(res.found) break;
res.tree.push(key);
findPosition(obj[key], mykey, myval, res);
}
if(!res.found) res.tree.pop();
}
} else if(is(obj, "Array")){
for(let i = 0; i < obj.length; i++){
if(res.found) break;
res.tree.push(i);
findPosition(obj[i], mykey, myval, res);
}
if(!res.found) res.tree.pop();
} else {
res.tree.pop();
}
return res;
}
Usage and output
findPosition([{one: { two: [{id: [{id:'my'}]}]}}], "id", "mys", {tree:[], found: false})
> tree: Array(0), found: false}
findPosition([{one: { two: [{id: [{id:'my'}]}]}}], "id", "my", {tree:[], found: false})
> {found: true, tree: [0, "one", "two", 0, "id", 0, "id"]}
For finding if current obj you are iterating over is an Array you can also use Array.isArray

Nesting a parent child relationship in lodash, given the parent id and children

How would I be able to nest json object if the parent and its children was given as a property.
The data looks like:
"1": {
"id": 1,
"name": "foo",
"parent": null,
"root": 1,
"children": [2, 4, 6],
"posts":[
{ "id": "1", "name": "item1" },
{ "id": "2", "name": "item2" },
{ "id": "3", "name": "item3" }
]
},
"2": {
"id": 2,
"name": "bar",
"parent": 1,
"root": 1,
"children": null,
"posts":[
{ "id": "4", "name": "item4" }
]
},
"3": {
"id": 3,
"name": "bazz",
"parent": null,
"root": 3,
"children": [5, 7],
"posts":[
{ "id": "5", "name": "item5" },
{ "id": "6", "name": "item6" }
]
},
....
A simple groupby using lodash won't do it.
var group = _.groupBy(data, 'parent');
Here is a fiddle:
http://jsfiddle.net/tzugzo8a/1/
The context of question is a nested categories with subcategories, and categories can have categories and posts in them.
Basically I don't want to have a different property for children and posts, since they are all children of a parent.
Desired output
"1": {
"id": 1,
"name": "foo",
"parent": null,
"root": 1,
"isCategory": true,
"children": [
{
"id": 2,
"name": "bar",
"parent": 1,
"root": 1,
"isCategory": true,
"children": null
},
{ "id": "1", "name": "item1", isCategory: false },
{ "id": "2", "name": "item2", isCategory: false },
{ "id": "3", "name": "item3", isCategory: false }
]
...
}

This is my take on the question (fiddle):
var data = getData();
var group = getTree(data);
console.log(group);
function getTree(flat) {
return _.reduce(flat, function (treeObj, item, prop, flatTree) {
var children = _.map(item.children, function (childId) {
return _.set(flatTree[childId], 'isCategory', true);
}).concat(_.map(item.items, function(item) {
return _.set(item, 'isCategory', false);
}));
item.children = !!children.length ? children : null;
delete item.items;
item.parent === null && (treeObj[prop] = item);
return treeObj;
}, {});
}

Take a look on the updated fiddle:
var data = getData();
_.keys(data).forEach(function(id){
var element = data[id];
if (element.children === null){
element.children = [];
}
element.isCategory = true;
element.items.forEach(function(item){
item.isCategory = false;
})
});
_.keys(data).forEach(function(id){
var element = data[id];
element.children = element.children.map(function(childId){
return data[childId];
}).concat(element.items);
});
_.keys(data).forEach(function(id){
delete data[id].items;
});
console.log(JSON.stringify(_.findWhere(_.values(data), {'parent': null})));
