access values of an object javascript - javascript

I am a beginning in javascript. So i have this data with the basic structure like so...
{
"status": "active",
"experimental": false,
"expansion": {
"extension": [
{
"valueBoolean": true
}
],
"contains": [
{
"system": "http://snomed.info/sct",
"code": "8989938493",
"display": "Acute"
},
{
"system": "http://snomed.info/sct",
"code": "889080980089",
"display": "Chronic"
},
{
"system": "http://snomed.info/sct",
"code": "889080980089",
"display": "Fragile"
}
]
}
}
I want to iterate over "contains" and put the values of "display" in an array so i can use it in a react component. I am currently struggling to achieve that. Any help will be appreciated. Thanks in advance.


You can use the map function to transform an array:
const myObject = {
"status": "active",
"experimental": false,
"expansion": {
"extension": [
{
"valueBoolean": true
}
],
"contains": [
{
"system": "http://snomed.info/sct",
"code": "8989938493",
"display": "Acute"
},
{
"system": "http://snomed.info/sct",
"code": "889080980089",
"display": "Chronic"
},
{
"system": "http://snomed.info/sct",
"code": "889080980089",
"display": "Fragile"
}
]
}
}
const arr = myObject.expansion.contains.map(({display})=>display)
console.log(arr)


let res = [];
const obj = {
"status": "active",
"experimental": false,
"expansion": {
"extension": [
{
"valueBoolean": true
}
],
"contains": [
{
"system": "http://snomed.info/sct",
"code": "8989938493",
"display": "Acute"
},
{
"system": "http://snomed.info/sct",
"code": "889080980089",
"display": "Chronic"
},
{
"system": "http://snomed.info/sct",
"code": "889080980089",
"display": "Fragile"
}
]
}
}
obj.expansion.contains.forEach(el => res.push(el.display));
console.log(res)

How to structure and all data in the objective from Json at App script

The JSON data I am working on it. This is coming from Facebook ad API. This is being build for google data studio connector
{
"data": [
{
"adcreatives": {
"data": [
{
"actor_id": "8834759718540",
"id": "538"
}
]
},
"insights": {
"data": [
{
"ad_id": "34536578578",
"impressions": "89108",
"actions": [
{
"action_type": "comment",
"value": "02"
},
{
"action_type": "post",
"value": "03"
}
],
"date_start": "2022-06-11",
"date_stop": "2022-07-10"
}
],
"paging": {
"cursors": {
"before": "MAZDZD",
"after": "MAZDZD"
}
}
},
"created_time": "2022-06-10T22:59:33+0600",
"id": "34536578578"
},
{
"adcreatives": {
"data": [
{
"actor_id": "7834759718970",
"id": "342"
}
]
},
"insights": {
"data": [
{
"ad_id": "238509545896206",
"impressions": "57803",
"actions": [
{
"action_type": "post_engagement",
"value": "2102"
},
{
"action_type": "page_engagement",
"value": "03"
}
],
"date_start": "2022-06-11",
"date_stop": "2022-07-10"
}
],
"paging": {
"cursors": {
"before": "MAZDZD",
"after": "MAZDZD"
}
}
},
"created_time": "2022-06-11T22:59:33+0600",
"id": "238509545896206"
}
],
"paging": {
"cursors": {
"before": "dfgdfgdfgdfsdgdfgdfgdfgdfgdgdg",
"after": "yuyuyuyutyuytuyutytynfrgersggsgs"
}
}
}
Here is the JavaScript code I have used in google app script but it is showing error. I know it is totally wrong
var data = {data: parseData.data.map(({actions, ...rest}) => ({...rest,...Object.fromEntries(actions.map(({action_type, value}) =>[action_type, value]))}))};
console.log(data);
Output should be like the following way so that I can get all the data in objective
{
"data": [
{
"actor_id": "8834759718540",
"id": "538",
"ad_id": "34536578578",
"impressions": "89108",
"comment": "02",
"post": "03",
"date_start": "2022-06-11",
"date_stop": "2022-07-10",
"created_time": "2022-06-10T22:59:33+0600"
},
{
"actor_id": "7834759718970",
"id": "342",
"ad_id": "238512373324806",
"impressions": "57803",
"post_engagement": "2102",
"page_engagement": "03",
"date_start": "2022-06-11",
"date_stop": "2022-07-10"
"created_time": "2022-06-11T22:59:33+0600"
}
],
"paging": {
"cursors": {
"before": "MAZDZD",
"after": "MQZDZD"
}
}
}

You can try the code below, but it only works if adcreatives.data and insights.data have only 1 element :
let part = data.data.map(item => ({
"actor_id": item.adcreatives.data.at(0).actor_id,
"id": item.adcreatives.data.at(0).id,
"ad_id": item.insights.data.at(0).ad_id,
"impressions": item.insights.data.at(0).impressions,
"comment": item.insights.data.at(0).actions.at(0).value,
"post": item.insights.data.at(0).actions.at(1).value,
"date_start": item.insights.data.at(0).date_start,
"date_stop": item.insights.data.at(0).date_stop,
"created_time": item.created_time
}));
let result = {
data: part,
paging: data.paging
}
console.log(result);

How to update a value in a complex fhirBundle JSON?

Given a bewildering fhir document like https://raw.githubusercontent.com/Notarise-gov-sg/api-notarise-healthcerts/master/test/fixtures/v2/pdt_art_with_nric_unwrapped.json
I need to update the part the JSON from { "id": "NRIC-FIN", "value": "S9098989Z" } to { "id": "NRIC-FIN", "value": "foobar" } and then emit the whole JSON again with that change.
I just about know how to access the value.
const fs = require("fs");
let rawdata = fs.readFileSync("pdt_art_with_nric_unwrapped.json");
let art = JSON.parse(rawdata);
let nric = art.fhirBundle.entry
.flatMap((entry) => entry.resource)
.find((entry) => entry.resourceType === "Patient")
.identifier.find((entry) => entry.id === "NRIC-FIN").value;
console.log(nric);
Though I am puzzled how to update this value since it's so difficult to access. Am I missing a trick? I don't want to use regex btw!

You seem to be very close - why not just set .value using the syntax you already have...?
const fs = require("fs");
let rawdata = fs.readFileSync("pdt_art_with_nric_unwrapped.json");
let art = JSON.parse(rawdata);
let nric = art.fhirBundle.entry
.flatMap((entry) => entry.resource)
.find((entry) => entry.resourceType === "Patient")
.identifier.find((entry) => entry.id === "NRIC-FIN").value = 'foobar';
console.dir(art.fhirBundle.entry)
... results in:

... clearly showing foobar set as you seem to desire. (Feel free to test with this Repl.it).
To "emit the full JSON" again you would just re-stringify it:
let fullJSON = JSON.stringify(art);

Instead of traversing the object manually you can use library like Jsonpath:
function replace() {
data = JSON.parse(data);
jsonpath.apply(data,
'$.fhirBundle.entry[?(#.resource.resourceType == "Patient")].resource.identifier[?(#.id == "NRIC-FIN")].value',
function(value) {
document.body.innerHTML += `value=${value}<br>`;
return 'foobar';
});
document.body.innerHTML += `updated JSON:<br> <pre>${JSON.stringify(data, undefined, 2)}</pre`;
}

If you are flat out replacing values without any other logic, and in case if you decide to use RegEx, then you can use String.replace().
let data =

}`
let targetId = 'NRIC-FIN';
let find = new RegExp(`(?<=${targetId}.*value":\\s*").*?(?=")`, 'ig');
data = data.replace(find, 'foobar');;
document.write(`<pre>${data}</pre>`);
Note: In the regular expression, I have used i flag for case insensitive search. Used g flag to replace all occurrences of the id. If the id is unique and there is going to be only one occurrence in entire .json file then don't use g flag.

I only know to use delete key by names such as
delete myjson.etag
delete myjson.names[0].metadata
How do I iterate the complete json since some of the json has arrays and nested structures which are not known in advance.
Hence a remove_keys(myjson, ["etag","memberships","formattedType","metadata"]) should render a result
var myjson {
"names": [{
"unstructuredName": "Natalie Victor",
"displayNameLastFirst": "Victor, Natalie",
"familyName": "Victor",
"displayName": "Natalie Victor",
"givenName": "Natalie",
}],

}

You need a recursive function for this task:
function filter(obj: any, list: string[]) {
if (obj && typeof obj === 'object') {
for (let item in obj) {
if (list.includes(item)) {
delete obj[item];
} else {
if (Array.isArray(obj[item])) {
for (let el of obj[item]) {
filter(el, list);
}
} else {
filter(obj[item], list);
}
}
}
}
return obj;
}
// example usage:
let a = {b: 5, c: 6, d: { a: 1, b: 2}}
filter(a, ['b']);
console.log(a);

Conversely, it may be faster in some interpreters to rebuild the object, rather than delete keys.
function removeKeys(obj, keys) {
if (Array.isArray(obj))
return obj.map(v => removeKeys(v, keys))
else if (typeof obj == "object" && obj != null) {

Need to get Name, Node Name and Phase Values from API

I am trying to get Name, Node Name and Phase values from JSON Data using JavaScript. Here is my JavaScript
<script>
$(document).ready(function () {
$.getJSON('http://ec2-3-82-117-70.compute-1.amazonaws.com:8080/api/v0/retrievePodStatus/default',
function (data) {
console.log(data)
document.body.append("Name: " + data.items[1].metadata.name);
// document.body.append(data.items[1].metadata.name);
// document.body.append(data.items[0].spec.nodeName);
});
});
</script>
I am just getting the name in here. Can someone please help me how to get Name, Node Name and Phase Values? find the below JSON as well.

Thanks, Much Appreciated

You were close with the code you posted. You just needed items[0] instead of items[1]. Remember the first element of an array is always 0. Other than that its as easy as checking the open and close brackets [] or {} to see where each nested object/array starts and ends.
Code:
var name = data.items[0].metadata.name
var nodeName = data.items[0].spec.nodeName
var phase = data.items[0].status.phase
snippet:
var data = {
"apiVersion": "v1",

How we remove full object of array from array of object using JavaScript or lodash?

My JSON looks like this:
{
"success": true,
"data": [
{
"user": {
"firstname": "demo",
test1": {
"role": {
"name": "demo"
},
"status": "pending",
"test2": {
"telephone": "+demo"
}
}
},
"authData": [
{
"_key": "demo",
"_id": "demo",
}
]
}
],
"session": {
"_key": "demo",
"uid": "demo",
}
}
I want to remove authData array from JSON.

First your JSON is invalid. This is corrected version:
{
"success": true,
"data": [
{
"user": {
"firstname": "demo",
"test1": {
"role": {
"name": "demo"
},
"status": "pending",
"test2": {
"telephone": "+demo"
}
}
},
"authData": [
{
"_key": "demo",
"_id": "demo"
}
]
}
],
"session": {
"_key": "demo",
"uid": "demo"
}
}
Now you can use DELETE operator to delete your key.
