First, filter array to get current page based on id. And iterate over the properties to create the list. For test, pageId is set to 2.
$(function(){
var json =
[
{
"id": "2",
"slug": "parent",
"title": "Parent",
"subcategories": [
{
"id": "12",
"slug": "child1",
"title": "child1"

{
"id": "14",
"slug": "child2",
"title": "child2"
},
{
"id": "15",
"slug": "child3",
"title": "child3"
},
{
"id": "16",
"slug": "child4",
"title": "child4"
}
]
},
{
"id": "11",
"slug": "parent2",
"title": "Parent2",
"subcategories": [
{
"id": "32",
"slug": "child1",
"title": "child1"
},
{
"id": "33",
"slug": "child2",
"title": "child3"
}
]
}
]
var pageId = 2;
var currentPage = json.filter(function(el){
return el.id == pageId;
})[0];
$.each(currentPage.subcategories, function(index, obj){
$('#list-category-slider').append('<div class="item">' + obj.title + '</div>');
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Extract the parent node name from Tree who has childrens

I want to iterate the tree and need to get the id of all the nodes which has the children in string array. while looping it is just returning me the record but doesn't extract the name of the node.
e.g const result = ['root', 'USER', 'ROLE', 'DASHBOARD', 'BRAND', 'COMPANY'];
{
"id": "root",
"name": "Roles and Permissions",
"children": [
{
"id": "USER",
"name": "USER",
"children": [
{
"id": "1",
"name": "VIEW"
},
{
"id": "2",
"name": "CREATE"
},
{
"id": "3",
"name": "EDIT"
}
]
},
{
"id": "ROLE",
"name": "ROLE",
"children": [
{
"id": "8",
"name": "VIEW"
},
{
"id": "9",
"name": "CREATE"
},
{
"id": "10",
"name": "EDIT"
},
{
"id": "11",
"name": "DELETE"
}
]
},
{
"id": "DASHBOARD",
"name": "DASHBOARD",
"children": [
{
"id": "BRAND",
"name": "BRAND",
"children": [
{
"id": "52",
"name": "VIEW"
},
{
"id": "53",
"name": "CREATE"
},
{
"id": "54",
"name": "EDIT"
},
{
"id": "55",
"name": "DELETE"
}
]
},
{
"id": "COMPANY",
"name": "COMPANY",
"children": [
{
"id": "56",
"name": "VIEW"
},
{
"id": "57",
"name": "CREATE"
},
{
"id": "58",
"name": "EDIT"
},
{
"id": "59",
"name": "DELETE"
}
]
}
]
}
]
}
I tried various looping method to get the list, e.g. but not returning the exact name of the node.
function getParent(nodes) {
if(Array.isArray(nodes.children)) {
return nodes.children.map((node) => getParent(node));
}
return nodes.name;
}

You can store the resp in an array and return that array.
const q = {
"id": "root",
"name": "Roles and Permissions",
"children": [
{
"id": "USER",
"name": "USER",
"children": [
{
"id": "1",
"name": "VIEW"
},
{
"id": "2",
"name": "CREATE"
},
{
"id": "3",
"name": "EDIT"
}
]
},
{
"id": "ROLE",
"name": "ROLE",
"children": [
{
"id": "8",
"name": "VIEW"
},
{
"id": "9",
"name": "CREATE"
},
{
"id": "10",
"name": "EDIT"
},
{
"id": "11",
"name": "DELETE"
}
]
},
{
"id": "DASHBOARD",
"name": "DASHBOARD",
"children": [
{
"id": "BRAND",
"name": "BRAND",
"children": [
{
"id": "52",
"name": "VIEW"
},
{
"id": "53",
"name": "CREATE"
},
{
"id": "54",
"name": "EDIT"
},
{
"id": "55",
"name": "DELETE"
}
]
},
{
"id": "COMPANY",
"name": "COMPANY",
"children": [
{
"id": "56",
"name": "VIEW"
},
{
"id": "57",
"name": "CREATE"
},
{
"id": "58",
"name": "EDIT"
},
{
"id": "59",
"name": "DELETE"
}
]
}
]
}
]
}
let result = []
function r(nodes){
if(Array.isArray(nodes.children)){
result.push(nodes.name);
nodes.children.map((c) => r(c))
return result;
}
return result;
}
console.log(r(q))

You can simply use a recursive function. Here ids is an array. You can initialize it before calling the function. Call this function in your getting IDs method.
const getIdFromNodesWithChild = (node) => {
if (node.children != undefined){
ids.push(node.id)
const children_list = node.children
children_list.forEach( new_child => getIdFromNodesWithChild(new_child))
}}
caller function
const returnIds = (tree) => {
ids = []
getIdFromNodesWithChild(tree)
return (ids)
}
result : ['root', 'USER', 'ROLE', 'DASHBOARD', 'BRAND', 'COMPANY']

angular 3 nested object

Can someone help me regarding my code I already search but had no luck on logic.
i am trying to get a nested drop but i get the same result on 3-child hierarchy.
this is the data from my API.

this.data = result.body.data;
let parents = this.data.filter(x => x.parent == null);
let child_id = [];
let child_id2 = [];
for (let i = 0; i < parents.length; i++) {
let _myTreelist = new ParentData();
_myTreelist.data.parent = parents[i].name;
child_id = this.data.filter(x => x.parent == parents[i].id); //get child-1 with id
_myTreelist.data.child.child1 = child_id.map((item) => {
return item.name
})
for (let e = 0; e < child_id.length; e++) { //10 ids
child_id2 = this.data.filter(a => a.parent === child_id[e].id); //get child-2 with id
_myTreelist.data.child.child.child2 = child_id2.map((item) => {
return item.name
})
}
this.parentList.push(_myTreelist);
}
this is the image output I get.
it works the first and 2nd nested but in the 3rd it display same

make a recursive function
getChild(element:any,data:any[])
{
element.children=data.filter((x:any)=>x.parent==element.id)
if (element.children.length)
element.children.forEach((x:any)=>this.getChild(x,data))
else
element.children=null;
return element
}
then
treeData=this.data.filter(x=>!x.parent)
.map(x=>this.getChild(x,this.data))
stackblitz
If you use an API and an observable use pipe map
treeData$=this.service.getData().pipe(
map((data:any[])=>{
return data.filter(x=>!x.parent).map(x=>this.getChild(x,data))
})
)

add id_parent to nested tree array in javascript or typescript

I have a nested array of tree type, each item has an id, I would like to add to the children the id_parent that would be the id of its ancestor array
let data = [
{
"id": "1",
"nombre": "TITULO A",
"children": [
{
"id": "2",
"nombre": "SUB TITULO A",
"children": [
{
"id": "3",
"nombre": "ITEM A",
"children": [
{
"id": "4",
"nombre": "SUB ITEM A",
"children": [
{
"id": "5",
"nombre": "DETALLE ITEM A",
"children": []
},
{
"id": "6",
"nombre": "DETALLE ITEM A2",
"children": []
}
]
}
]
}
]
}
]
},
{
"id": "7",
"nombre": "TITULO B",
"children": [
{
"id": "8",
"nombre": "SUB TITULO B",
"children": [

}
]
},
{
"id": "13",
"nombre": "ITEM B2",
"children": []
}
]
}
]
}
]
}
}
expected result
let result = [
{
"id": "1",
"id_parent": null,
"nombre": "TITULO A",
"children": [
{
"id": "2",
"id_parent": "1",
"nombre": "SUB TITULO A",
"children": [
{
"id": "3",
"id_parent": "2",
"nombre": "ITEM A",
"children": [
{
.
.
.

I found a solution, using a recursive function, which iterates if children has items.
addParent(data){
let parent = null;
Object.keys(data).forEach(x => {
this.setParent(data[x], parent);
});
}
setParent(node, parent){
node.id_parent = parent;
node.children.forEach(x => {
this.setParent(x, node.id);
});
}

Sorting API JSON response using Javascript

I am getting below response on hitting DoctorData.api and want to sort them all with their 'ID'. Can someone show me how to sort the Output JSON data and display it same format.
Kindly Excuse my coding skills, this is my second test case. I am new to JS.
var doctorIDgeturl = geturl.geturls.getapiUrl; //'getapiUrl' is Doctor Get API
var res = await api.getRequest(doctorIDgeturl);
logger.logger().info('GET_data = ', JSON.stringify(res.data, null, 2));
var rescount = Object.keys(res.data.data.doctorList); //doctorList is the API response object for above GET API
console.log("This is Sorted Id: ");
const sortedResponse = sort(res.data, r => r.doctorListModels.associateId, ['asc']) //using ascending order to sort
console.log(sortedResponse);
Current output:

parseInt(r.doctorListModels.associateId) or +r.doctorListModels.associateId
it seems like it sorts the id as string not number

Sorry I can't comment because of low reputation, but here is solution.
const obj = {

In order to get the JSON response I need to put startDate (the moment user searches the vacant rooms, in this situation it is: 2017-04-27T10:55) and endDate (set to end of the day, 2017-04-27T22:00). The result for this query is the JSON response above.
The problem is that the API I'm using doesn't contain any data for the vacant rooms but only for the ones booked for certain times so I made a list of all the rooms in the building and compared it to the booked ones to filter them out:
var rooms = ['A120.3', 'A130.1', 'A130.3', 'A140.1', 'A140.2', 'A140.4', 'A250.1', 'A240.4', 'A240.2', 'A220.5', 'A220.3',
'A220.1', 'A210.2', 'A320.2', 'A320.6', 'A320.7', 'A320.8', 'A340.1', 'A340.2', 'A350.1', 'A350.3', 'A440.5', 'A450.3','A450.1',
'A440.4', 'A440.2', 'A420.6', 'A420.5', 'A420.4', 'A420.2', 'A510.2', 'A520.5', 'A510.4', 'A520.6', 'A520.7','A540.1', 'A540.2'];
var data = JSON.parse(responseText);
var booking = Object.create(null);
var free;
data.reservations.forEach(function (reservation) {
reservation.resources.some(function (resource) {
if (resource.type === 'room') {
booking[resource.code] = booking[resource.code] || [];
booking[resource.code].push({ startDate: reservation.startDate, endDate: reservation.endDate });
return true;
}
});
});
free = rooms.filter(function (a) {
return !booking[a];
});
console.log(free);
Results:
A210.3
A220.5
A320.2
A520.6
A510.4
This only returns the ones that are not being used at all during the day but I need to get the ones that are vacant for hour or two.
For this booked class for example:
"startDate": "2017-04-27T13:15:00",
"endDate": "2017-04-27T16:00:00",
"type": "room",
"code": "A520.5"
for this I would need to print out:
A520.5 - 2 hours 20 minutes
So I need to get the room / time from the startDate of the search (2017-04-27T10:55) and compare it to the startDate of the booked room (2017-04-27T13:15:00) to get the time remaining for that room to be vacant.
TO CLARIFY:
I have all the data for booked rooms starting from 2017-04-27T10:55
until 2017-04-27T22:00 as you can see from the JSON response above.
I need to somehow compare the startDate of the JSON query when the user
searches for the rooms (2017-04-27T10:55) and compare it to the booked
rooms startDate to get the time how long the room stays vacant.
This is how I'm doing my startDate and endDate for the JSON query:
// Timestamp needs to be formed (YYYY-MM-DDTxx:xx) in order for JSON query to work
var todaysDate = new Date();
function convertDate(date) {
var yyyy = date.getFullYear().toString();
var mm = (date.getMonth() + 1).toString();
var dd = date.getDate().toString();
var mmChars = mm.split('');
var ddChars = dd.split('');
return yyyy + '-' + (mmChars[1] ? mm : "0" + mmChars[0]) + '-' + (ddChars[1] ? dd : "0" + ddChars[0]);
}
// Current time when user searches for vacant rooms
var currentTime = new Date();
var time = "T" + currentTime.getHours() + ":" + currentTime.getMinutes();
// variables for the JSON query
var startDate = convertDate(todaysDate) + time;
var endDate = convertDate(todaysDate) + ("T22:00");
// JSON-query
var getRooms = {
"startDate": startDate,
"endDate": endDate
};
