Postman JSON parse response body arrays inside arrays

I have this JSON Response from API call
[
{
"id": 20599,
"name": "Deliver",
"options": [
{
"id": 63775,
"name": "Item",
"dataType": "SelectMultiOption",
"required": false,
"options": [
{
"id": 426,
"name": "Towels"
},
{
"id": 427,
"name": "Toothbrush"
},
{
"id": 428,
"name": "Pillow"
}
]
}
]
}
]
I am using this code to get the id of the service "Deliver"
var data = JSON.parse(responseBody);
var loop_count = 0
for (count = 0; count < data.length; count++)
{
if (data[count].name == "Deliver")
{
var job_id = data[count].id;
postman.setEnvironmentVariable("service_id", job_id);
}
}
The questions are:
How can I get value from array "options", I need to get the "id":
63775 and store as "item_id" and the "name":"Item" as "item_name" postman variables.
Then I need to select the "options" nested in record
"Item" and select the option "name": "Toothbrush" and store in postman
variable "svc_optn_optn_name" and it's "id" stored in
"svc_optn_optn_id"

Here I am giving my own suggestion for your problem with few lines of code. I am not sure, how are you going to use these values. I also don't know if the outer options array will always have 1 item or more. I have just tried to satisfy your questions.
Please ask/comment, if you have more doubts or I am wrong.
I have created a function getAllPostmanDataFrom(obj) which takes object as parameter which is the value of data[count], gathers necessary info in other object postmanObj and returns it to the caller.
function getAllPostmanDataFrom(obj) {
const item_id = obj.options[0].id;
const item_name = obj.options[0].name;
const svc_optn_optn_name = obj.options[0].options[1].name;
const svc_optn_optn_id = obj.options[0].options[1].id;
const postmanObj = {item_id, item_name, svc_optn_optn_id, svc_optn_optn_name}; // Return object
return postmanObj;
}
var data = [
{
"id": 20599,
"name": "Deliver",
"options": [
{
"id": 63775,
"name": "Item",
"dataType": "SelectMultiOption",
"required": false,
"options": [
{
"id": 426,
"name": "Towels"
},
{
"id": 427,
"name": "Toothbrush"
},
{
"id": 428,
"name": "Pillow"
}
]
}
]
}
]
var count = 0;
var obj = data[count];
var postmanObj = getAllPostmanDataFrom(obj);
//var {item_id, item_name, svc_optn_optn_id} = postmanObj;
console. log(postmanObj)
/*
console.log(item_id);
console.log(item_name);
console.log(svc_optn_optn_id);
console.log(svc_optn_optn_name);
*/
Finally, you can use values contained in postmanObj as follows:.
postman.setEnvironmentVariable("item_id", postmanObj.item_id);
postman.setEnvironmentVariable("item_name", postmanObj.item_name);
And so on.

This is the solution
var data = JSON.parse(responseBody);
variable named as data
var loop_count = 0
for (count = 0; count < data.length; count++)
{
if (data[count].name == "Deliver")
{
var job_id = data[count].id;
postman.setEnvironmentVariable("service_id", job_id);
var job1_name = data[count].options[0].name;
postman.setEnvironmentVariable("item_name", job1_name);
var job2_id = data[count].options[0].id;
postman.setEnvironmentVariable("item_id", job2_id);
var job3_id = data[count].options[0].options[1].id;
postman.setEnvironmentVariable("svc_optn_optn_id", job3_id);
var job4_name = data[count].options[0].options[1].name;
postman.setEnvironmentVariable("svc_optn_optn_name", job4_name);
}

const data = JSON.parse(responseBody);
data.forEach(item => {
console.log(item.id); // deliver object id.
item.options.forEach(option => {
console.log(`Option Id ${option.id}`); // option id
postman.setEnvironmentVariable("service_id", option.id);
option.options(optionItem => {
if(optionItem.name == 'Toothbrush'){
postman.setEnvironmentVariable("svc_optn_optn_name", optionItem.name);
postman.setEnvironmentVariable("svc_optn_optn_id", optionItem.id);
}
});
});
});

Converting CSV to nested JSON in Javascript

I have a CSV file which needs to be converted into a Javascript object / JSON file. Doesn't really matter which since I'll be be handling the data in JS anyway and either is fine.
So for instance this:
name,birthday/day,birthday/month,birthday/year,house/type,house/address/street,house/address/city,house/address/state,house/occupants
Lily Haywood,27,3,1995,Igloo,768 Pocket Walk,Honolulu,HI,7
Stan Marsh,19,10,1987,Treehouse,2001 Bonanza Street,South Park,CO,2
should become this:
[
{
"name": "Lily Haywood",
"birthday": {
"day": 27,
"month": 3,
"year": 1995
},
"house": {
"type": "Igloo",
"address": {
"street": "768 Pocket Walk",
"city": "Honolulu",
"state": "HI"
},
"occupants": 7
}
},
{
"name": "Stan Marsh",
"birthday": {
"day": 19,
"month": 10,
"year": 1987
},
"house": {
"type": "Treehouse",
"address": {
"street": "2001 Bonanza Street",
"city": "South Park",
"state": "CO"
},
"occupants": 2
}
}
]
This is what I have came up with:
function parse(csv){
function createEntry(header){
return function (record){
let keys = header.split(",");
let values = record.split(",");
if (values.length !== keys.length){
console.error("Invalid CSV file");
return;
}
for (let i=0; i<keys.length; i++){
let key = keys[i].split("/");
let value = values[i] || null;
/////
if (key.length === 1){
this[key] = value;
}
else {
let newKey = key.shift();
this[newKey] = this[newKey] || {};
//this[newKey][key[0]] = value;
if (key.length === 1){
this[newKey][key[0]] = value;
}
else {
let newKey2 = key.shift();
this[newKey][newKey2] = this[newKey][newKey2] || {};
this[newKey][newKey2][key[0]] = value;
//if (key.length === 1){}
//...
}
}
/////
}
};
}
let lines = csv.split("\n");
let Entry = createEntry(lines.shift());
let output = [];
for (let line of lines){
entry = new Entry(line);
output.push(entry);
}
return output;
}
My code works, however there is an obvious flaw to it: for each layer it goes down into (e.g. house/address/street), I have to manually write repeated if / else statements.
Is there a better way to write it? I know this involves recursion or iteration of some kind but I just can't seem to figure out how.
I've searched around SO but most questions seem to be on doing it in Python instead of JS.
As far as possible I wish to have this done in vanilla JS without any other libraries.

You can achieve the intended results by creating the Object recursively.
Look at the code below:
var csv = [
"name,birthday/day,birthday/month,birthday/year,house/type,house/address/street,house/address/city,house/address/state,house/occupants",
"Lily Haywood,27,3,1995,Igloo,768 Pocket Walk,Honolulu,HI,7",
"Stan Marsh,19,10,1987,Treehouse,2001 Bonanza Street,South Park,CO,2"
];
var attrs = csv.splice(0,1);
var result = csv.map(function(row) {
var obj = {};
var rowData = row.split(',');
attrs[0].split(',').forEach(function(val, idx) {
obj = constructObj(val, obj, rowData[idx]);
});
return obj;
})
function constructObj(str, parentObj, data) {
if(str.split('/').length === 1) {
parentObj[str] = data;
return parentObj;
}
var curKey = str.split('/')[0];
if(!parentObj[curKey])
parentObj[curKey] = {};
parentObj[curKey] = constructObj(str.split('/').slice(1).join('/'), parentObj[curKey], data);
return parentObj;
}
console.log(result);
.as-console-wrapper{max-height: 100% !important; top:0}
constructObj() function basically constructs the resultant object recursively by looking at the column name, so if the column name contains the / like in house/address/street it will create a key in the object by the name house and then recursively calls itself for the rest of the remaining keys in string i.e. address/street/. The recursion ends when no more / are left in the string and then it simply assigns the value in that key and returns the result object.

You can map over your records and create the objects on the fly :
let records = ['Lily Haywood,27,3,1995,Igloo,768 Pocket Walk,Honolulu,HI,7',
'Stan Marsh,19,10,1987,Treehouse,2001 Bonanza Street,South Park,CO,2']
let output = records.map( record => {
let arr = record.split(',')
return {
"name": arr[0],
"birthday": {
"day": parseInt(arr[1]),
"month": parseInt(arr[2]),
"year": parseInt(arr[3])
},
"house": {
"type": arr[4],
"address": {
"street": arr[5],
"city": arr[6],
"state": arr[7]
},
"occupants": parseInt(arr[8])
}
}
})
console.log(output)

How to add a new key to multiple indices of an array of objects?

I've got an array of three people. I want to add a new key to multiple objects at once based on an array of indices. Clearly my attempt at using multiple indices doesn't work but I can't seem to find the correct approach.
var array = [
{
"name": "Tom",
},
{
"name": "Dick",
},
{
"name": "Harry",
}
];
array[0,1].title = "Manager";
array[2].title = "Staff";
console.log(array);
Which returns this:
[
{
"name": "Tom",
},
{
"name": "Dick",
"title": "Manager"
},
{
"name": "Harry",
"title": "Staff"
}
]
But I'd like it to return this.
[
{
"name": "Tom",
"title": "Manager"
},
{
"name": "Dick",
"title": "Manager"
},
{
"name": "Harry",
"title": "Staff"
}
]

You cannot use multiple keys by using any separator in arrays.
Wrong: array[x, y]
Correct: array[x] and array[y]
In your case, it will be array[0].title = array[1].title = "manager";

1st method::
array[0].title = "Manager";
array[1].title = "Manager";
array[2].title = "Staff";
array[0,1] will not work.
2nd method::
for(var i=0;i<array.length;i++) {
var msg = "Manager";
if(i===2) {
msg = "Staff"
}
array[i].title = msg
}

You can use a helper function like this
function setMultiple(array, key, indexes, value)
{
for(i in array.length)
{
if(indexes.indexOf(i)>=0){
array[i][key] = value;
}
}
}
And then
setMultiple(array, "title", [0,1], "Manager");

Try this: `
for (var i=0; var<= array.length; i++){
array[i].title = "manager";
}`
Or you can change it around so var is less than or equal to any n range of keys in the index.
EDIT: instead make var <= 1. The point is to make for loops for the range of indices you want to change the title to.

Assuming that you have a bigger set of array objects.
var array = [
{
"name": "Tom",
},
{
"name": "Dick",
},
{
"name": "Harry",
},
.
.
.
];
Create an object for the new keys you want to add like so:
let newKeys = {
'Manager': [0,2],
'Staff': [1]
}
Now you can add more such titles here with the required indexes.
with that, you can do something like:
function addCustomProperty(array, newKeys, newProp) {
for (let key in newKeys) {
array.forEach((el, index) => {
if (key.indexOf(index) > -1) { // if the array corresponding to
el[newProp] = key // the key has the current array object
} // index, then add the key to the
}) // object.
}
return array
}
let someVar = addCustomProperty(array, newKeys, 'title')

Merging linked Data in Array in Javascript

I have a simple task of rearranging a couple of Arrays in a JSON, so ractive.js can handle it better. But I got carried away a bit, and the outcome was not particularly satisfactory.
An example of my initial Array:
[{
"_id": 1,
"type": "person",
"Name": "Hans",
"WorksFor": ["3", "4"],
}, {
"_id": 2,
"type": "person",
"Name": "Michael",
"WorksFor": ["3"],
}, {
"_id": 3,
"type": "department",
"Name": "Marketing"
}, {
"_id": 4,
"type": "department",
"Name": "Sales"
}, {
"_id": 5,
"type": "person",
"Name": "Chris",
"WorksFor": [],
}]
So with a given Department I wanted a method in ractive to give me all Persons who work in this Department (with a list of Departments they work for). Something like:
[{
"_id": 1,
"type": "person",
"Name": "Hans",
"WorksFor": ["3", "4"],
"Readable": ["Marketing", "Sales"]
}, {
"_id": 2,
"type": "person",
"Name": "Michael",
"WorksFor": ["3"],
"Readable": ["Sales"]
}]
The function that somehow came to life was similar to this:
function imsorryforthis() {
let output = [];
let tempdocs = this.get('docs'); //as this happens in a ractive method,
//"this.get" is neccesary for binding
for (var i = 0; i < tempdocs.length; i++) {
if (_.contains(tempdocs[i].WorksFor, givenDepartment)) { //I used underscore.js here
let collectedDepartmentData = [];
if (tempdocs[i].WorksFor.length > 0) {
for (var f = 0; f < tempdocs[i].WorksFor.length; f++) {
for (var g = 0; g < tempdocs.length; g++) {
if (tempdocs[i].WorksFor[f] == tempdocs[g]._id) {
let actualDepartmentData = {};
actualDepartmentData = tempdocs[g];
collectedDepartmentData.push(actualDepartmentData);
}
}
}
}
tempdocs[i].Readable = collectedDepartmentData;
output.push(tempdocs[i]);
}
}
return output;
}
I've put it in a Fiddle as well to make it better readable.
Due to the fact that somehow this monstrosity does work (I was astonished myself), it feels like scratching your left ear with your right hand over your head (while being constantly shouted at by a group of desperate mathematicians).
Maybe anybody knows a more presentable and smarter approach (or a way to compile JavaScript so this never sees the light of day again).

Construct a map department_id => department_name first:
let departments = {};
for (let x of data) {
if (x.type === 'department') {
departments[x._id] = x.Name;
}
}
Then, iterate over Persons and populate Readable arrays from that map:
for (let x of data) {
if (x.type === 'person') {
x.Readable = x.WorksFor.map(w => departments[w]);
}
}
Finally, extract Persons for the specific Department:
personsInSales = data.filter(x =>
x.type === 'person' && x.WorksFor.includes('3'));

Firstly, your data structure does not have a good design. You should not be returning person and department in the same array. If possible, try to redesign the initial data structure to make it more modular, by separating out the people and department into separate structures. However if you are stuck with this same data structure, you can write the code a little better. Please find the code below. Hope it helps!
function mapPeopleDepartment() {
var deptMap = {},peopleList = [];
//Iterate through the initialArray and separate out the department into a hashmap deptMap and people into a new peopleList
for(var i=0; i < initArray.length; i++) {
var obj = initArray[i];
obj.type == "department" ? deptMap[obj._id] = obj.Name : peopleList.push(obj);
}
//Iterate through the peopleList to map the WorksFor array to a Readable array
for(var i=0; i < peopleList.length; i++) {
var person = peopleList[i];
person.Readable = _.map(person.WorksFor, function(dept){return deptMap[dept]});
}
return peopleList;
}

one of JSON values returns unidentified with JavaScript

I need to retrieve email field from JSON with JavaScript.
Here is the code:
"contacts": [
{
"addedAt": 1332358711001,
"vid": 1,
"properties": {
"lastname": {
"value": "Mott"
},
"firstname": {
"value": "Adrian"
}
},
"identity-profiles": [
{
"vid": 1,
"identities": [
{
"type": "EMAIL",
"value": "test-fdfc6c2e-e19e-4138-8201-8342ca333aa1#hubspot.com",
"timestamp": 1332358711715
},
{
"type": "LEAD_GUID",
"value": "f3ebaf07-1c6d-4ada-af31-3559dd8b3027",
"timestamp": 1332358711771
}
]
}
]
}]
The code works with all fields, except when I get to Identities, it returns NULL or unidentified.
var temp = fields.contacts.length;
for (var i=0; i<fields.contacts.length; i++){
var addedAt = fields.contacts[i].addedAt;
var formattedDate = Utilities.formatDate(new Date(addedAt), "GMT", "yyyy-MM-dd");
var lastName = fields.contacts[i].properties.lastname.value;
var firstName = fields.contacts[i].properties.firstname.value;
var vid = fields.contacts[i].vid;
var ip = fields.contacts[i]['identity-profiles'];
var id = ip.identities;
}
var id always returns unidentified. Also doesn't work:
for (var j=0; i<id.length; j++){
if(typeof ['type'] == 'EMAIL'){
var email = id[j].value;
}
};

fields.contacts[i]['identity-profiles'] is an array, it doesn't directly have a identities property.
You may want
var id = ip[0].identities;
or you should iterate over fields.contacts[i]['identity-profiles'] but it's not clear what you precisely want.
