merge multilevel json object to create stagged object with no loss of data

I want to merge two multi-level object to form a single object with no loss of data.
till the level data is same no extra fields should be added, at level where fields are different new object should get inserted in the array.
we have to group json object of similar fields in one complete json.
multilevel object needs to be merged together to get one aggragated result.
my sample objects are as -
let one={
"name": "Hindi",
"country": "USA",
"region": "EAST COAST",
"enttity": "ENTITY-2",
"operation": [
{
"p_name": "RECONSTRUCTION",
"code": "jhhkj-132",
"class": "medical",
"products": [
{
"main": "electronic",
"area": [
{
"subarea": "electrical",
"use": 0,
"max_use": 0,
"mode_use": "10",
"median": "12",
"things": [
{
"id": "1000514",
"number": "1588TB-1",
"description": "DESCRIPTION1",
"manufacturer": "LG",
"tag": "NOT AVAILABLE",
}
]
}
]
}
]
}
]
};
let two={
"name": "Hindi",
"country": "USA",
"region": "EAST COAST",
"enttity": "ENTITY-2",
"operation": [
{
"p_name": "RECONSTRUCTION",
"code": "jhhkj-132",
"class": "medical",
"products": [
{
"main": "electronic",
"area": [
{
"subarea": "mechanical",
"use": 0,
"max_use": 0,
"mode_use": "10",
"median": "12",
"things": [
{
"id": "1000523314",
"number": "1588T3B-1",
"description": "DES32CRIPTION1",
"manufacturer": "LG",
"tag": "NOT AVAILABLE",
}
]
},
{
"subarea": "electrical",
"use": 0,
"max_use": 0,
"mode_use": "10",
"median": "12",
"things": [
{
"id": "1000514",
"number": "1588TB-1",
"description": "DESCRIPTION1",
"manufacturer": "LG",
"tag": "NOT AVAILABLE",
}
]
}
]
}
]
}
]
};
output json should be something like this->
let outpus={
"name": "Hindi",
"country": "USA",
"region": "EAST COAST",
"enttity": "ENTITY-2",
"operation": [
{
"p_name": "RECONSTRUCTION",
"code": "jhhkj-132",
"class": "medical",

{
"main": "electronic",
"area": [
{
"subarea": "mechanical",
"use": 0,
"max_use": 0,
"mode_use": "10",
"median": "12",
"things": [
{
"id": "1000523314",
"number": "1588T3B-1",
"description": "DES32CRIPTION1",
"manufacturer": "LG",
"tag": "NOT AVAILABLE",
}
]
},
{
"subarea": "electrical",
"use": 0,
"max_use": 0,
"mode_use": "10",
"median": "12",
"things": [
{
"id": "1000514",
"number": "1588TB-1",

"tag": "NOT AVAILABLE",
}
]
}
]
}
]
}
]
};

JavaScript time comparison with arrays

I'm working on a project where I need to get all the vacant classrooms for the day and basically filter out the ones being in use.
I get all the data from the school's own API with JSON response body that looks like this:

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
};

I can't seem to console.log the item name and just that. It's in the position data -> pricing -> tables -> items -> name. I am going for an output that says "Toy Panda".

I would really appreciate a tip. Thank you

If you store your JSON object into variable called obj you can access that value ("Toy Panda") with:
obj.data.pricing.tables[0].items[0].name
because tables and items are arrays.

Here is a sample example :
<script>
var data = '{"name": "mkyong","age": 30,"address": {"streetAddress": "88 8nd Street","city": "New York"},"phoneNumber": [{"type": "home","number": "111 111-1111"},{"type": "fax","number": "222 222-2222"}]}';
var json = JSON.parse(data);
alert(json["name"]); //mkyong
alert(json.name); //mkyong
</script>
Refer this link :[https://www.mkyong.com/javascript/how-to-access-json-object-in-javascript/][1]
In your case it should be something like :
var data = // your json;
var json = JSON.parse(data);
console.log(json.pricing.tables.items[0].name;

Indexing last number of a JSON Object

So I have a JSON object, here it is:

I want to know how to index the last thing of this json object. I can't describe it any more but it might be the key.
I want to basically index the last object in the object, so that would be the bit where it says "872":{"header":"New Hat" near the bottom
So basically it's the biggest number I want to index. I already tried to index the last one with [4] as an index but it came up with undefined.

I suppose that you might want this:
var str = '{"868":{"header":"New limited","lite":"1337 Gaming Headset","icon":"","items":{"Stock":"1,337","Price":"R$750"},"extra":{"product":25355494},"url":"","id":868,"added":1438542256903},"869":{"header":"New Face","lite":"Furious George","icon":"","items":{"Price":"R$200"},"extra":{"product":25355932},"url":"","id":869,"added":1438543456863},"870":{"header":"Almost sold out","lite":"1337 Gaming Headset","icon":"","items":{"Stock":"1,337","Remaining":"133","Price":"R$750"},"extra":{"product":25355494},"url":"","id":870,"added":1438544588831},"871":{"header":"Sold out","lite":"1337 Gaming Headset","icon":"","items":{"Price":"R$750"},"extra":{},"url":"","id":871,"added":1438544704049},"872":{"header":"New Hat","lite":"Elite Spy Eye","icon":"","items":{"Price":"R$250"},"extra":{"product":25356879},"url":"","id":872,"added":1438545677167}}';
var obj = JSON.parse(str);
var last = Object.keys(obj).sort(function(a, b) {
return parseInt(b) - parseInt(a);
})[0]; // suppose to be "872" in this case
console.log('"' + last + '": ' + JSON.stringify(obj[last]));

var json = {
"868": {
"header": "New limited",

Fetch particular data from nested json using MVC in backbone.js

I know to work out simple concepts using backbone.js.below is my nested json file
{
"Re":
{
"Si":
[
{
"Def":
{
"StName": "Gau00",
"SID": "1",
"Parent": "",
"ParentID": "",
"Ty": "GAU",
"TypID": "2"
},
"Entities":
[
{
"EntityId": "2003",
"Index": "1",
"Value": "00"
},
{
"EntityId": "2006",
"Index": "1",
"Value": "B"
},
{
"EntityId": "2004",
"Index": "1",
"Value": "B"
},
{
"EntityId": "5",
"Index": "1",
"Value": "54"
},
{
"EntityId": "9007",
"Index": "1",
"Value": "1"
},
{
"EntityId": "9703",
"Index": "1",
"Value": "0"
}
],
"Connections":
[
{
"SourceID": "2",
"DestinationID": "1"
}
]
},
{
"Def":
{
"StName": "Tan",
"ID": "2",
"Parent": "",
"ParentID": "",
"Ty": "TA",
"TypID": "3"
},
"Entities": "",
"Connections":
[
{
"SourceElementID": "5",
"DestinationID": "2"
},
{
"SourceID": "2",
"DestinationID": "1"
}
]
}
]
}
}
Now with the StName i have to get all the other details from this nested json using backbone.js.Can anyone help me with ideas.

First convert JSON string to Javascript Object then use the following algorithm:
for each element in "Si":
if element["Def"]:
if element["Def"]["StName"] == "YOUR REQUIRED VALUE":
return element["Def"]
Write a function that takes your object, and iterate through the object and check StName with your required value. If condition true, return the current object.
