How to get the modified object in angularjs - javascript

I have a requirement where I need to send modified value alone in the object.
Following is my object:
{
"Code": 200,
"ErrorMessage": null,
"Result": {
"Locations": [{
"LocationName": "Location 1",
"Address": "XYZ",
"City": "Houston",
"State": "TEXAS",
"StateCode": "TX",
"Zipcode": "75201"
},
{
"LocationName": "Location 2",
"Address": "ABC",
"City": "Germantown",
"State": "CALIFORNIA",
"StateCode": "CA",
"Zipcode": "90001"
}]
}
}
I used ng-repeat inorder to display data which has input fields. Now If I modify Location 1 in that Locations Object. I want to send only Location 1 details.
Is it possible to do that in Angular. I am new to angular.


you can use ng-change to get the modified object
angular.module("app",[])
.controller("ctrl",function($scope){
$scope.changeItem = function(item){
console.log(item.LocationName)
}
$scope.items = {
"Code": 200,
"ErrorMessage": null,
"Result": {
"Locations": [{
"LocationName": "Location 1",
"Address": "XYZ",
"City": "Houston",
"State": "TEXAS",
"StateCode": "TX",
"Zipcode": "75201"
},
{
"LocationName": "Location 2",
"Address": "ABC",
"City": "Germantown",
"State": "CALIFORNIA",
"StateCode": "CA",
"Zipcode": "90001"
}]
}
}
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.22/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
<div ng-repeat="item in items.Result.Locations">
<input ng-model="item.LocationName" ng-change="changeItem(item)"/>
</div>
</div>

I've JSON array which is returned after an edit success in react-redux-saga. The record I updated before and after successfull update comes together as an element of JSON array. So, I need to replace the old resort element with the newly updated resort values and also delete the old resort.
Here, in this example, I have updated resortId(id)=15, but my redux-saga returns both-old resort and the updated new resort,clubbed together in a single element in JSON array cuz in the this.props(cuz place part in this id=15 belongs to another saga store).

How do I delete the child element resort with id=15 as this is old record before the update? And how do I rename the id of "place" to "placeId" and merge the inner parts - placeId,city,state and country to the outer part of the element - name=BBB and Id=15 and address": "NewTown","details": "jhkhkjhkjhkjh","phone": "98789797" to something like this

I have deleted the "resort" but unable to rename id in place part to placeId and merge it to the outer element.
function deleteKey(obj, keyToDelete) {
Object.keys(obj).forEach(key => {
if (key.toLowerCase() === keyToDelete) {
delete obj[key];
}
value = obj[key];
if (value instanceof Object) {
deleteKey(value, keyToDelete);
}
});
}
deleteKey(resortafterupdate, "resort");

I found a solution to flatten the child props using this answe on this link
Solution
Here's the code I modified according to my needs
function deleteKey(obj, keyToDelete) {
Object.keys(obj).forEach(key => {
if (key.toLowerCase() === keyToDelete) {
delete obj[key];
}
value = obj[key];
if (value instanceof Object) {
deleteKey(value, keyToDelete);
}
});
}
Object.flatten = function(data){
var resultMain = [];
var result = {};
function recurse(cur, prop){
if (Object(cur) !== cur){
result[prop] = cur;
}else if(Array.isArray(cur)){
for(var i=0, l=cur.length; i<l; i++)
recurse(cur[i], prop);
if(l == 0)
result[prop] = [];
}else{
var isEmpty = true;
for(var p in cur){
isEmpty = false;
recurse(cur[p], prop==="place" && p==="id"? prop+"Id" : p);
}
if(isEmpty && prop)
result[prop] = {};
}
}
for(var i=0; i<data.length; i++){
result = {};
recurse(data[i], "");
resultMain[i] = result;
}
return resultMain;
}
deleteKey(updateResorts, "resort");
console.log(Object.flatten(newlyaddedResort));

Modify JSON object using JavaScript based on title search

I have a ASP.Net hidden field which has data in JSON format as shown below
[
{
"RegionName": "USA",
"Contact": {
"LegalName": "somethinglegal",
"StreetAddress": "hello",
"City": "Test",
"State": "Test",
"Zip": "8888",
"Country": "USA",
"VAT": "VAT"
},
"EntityContact": {
"LegalName": "Test",
"Email": "Test#test.com",
"Phone": "9998887777"
}
},
{
"RegionName": "Mexico",
"Contact": {
"LegalName": "somethinglegal",
"StreetAddress": "hello",
"City": "Test",
"State": "Test",
"Zip": "33333",
"Country": "Mexico",
"VAT": "VAT"
},
"EntityContact": {
"LegalName": "Amex",
"Email": "test#test.com",
"Phone": "9998887777"
}
}
]
which is read in Javascript using below code
var value = $('#countryInvoice')[0].defaultValue;
Now I want to search this JSON using javascript based on Region name and delete the record from the hidden field. So I want to remove the data point for say USA so only the below remains
[
{
"RegionName": "Mexico",
"Contact": {
"LegalName": "somethinglegal",
"StreetAddress": "hello",
"City": "Test",
"State": "Test",
"Zip": "33333",
"Country": "Mexico",
"VAT": "VAT"
},
"EntityContact": {
"LegalName": "Amex",
"Email": "test#test.com",
"Phone": "9998887777"
}
}
]
Can someone please tell me how to do it in JQuery or Javascript.
Thanks

//ES5
var res = value.filter(function(e) { return e["RegionName"] != "USA"; })
//ES6
var res = value.filter(e => e["RegionName"] != "USA")
Note: The Arrow function is ES6 syntax.

You just need to filter it out using Array.prototype.filter().
Check out the MDN Docs here
The snippet below filters out USA
let value = [{
"RegionName": "USA",
"Contact": {
"LegalName": "somethinglegal",
"StreetAddress": "hello",
"City": "Test",
"State": "Test",
"Zip": "8888",
"Country": "USA",
"VAT": "VAT"
},
"EntityContact": {
"LegalName": "Test",
"Email": "Test#test.com",
"Phone": "9998887777"
}
},
{
"RegionName": "Mexico",
"Contact": {
"LegalName": "somethinglegal",
"StreetAddress": "hello",
"City": "Test",
"State": "Test",
"Zip": "33333",
"Country": "Mexico",
"VAT": "VAT"
},
"EntityContact": {
"LegalName": "Amex",
"Email": "test#test.com",
"Phone": "9998887777"
}
}
];
let newArray = value.filter(arr => arr.RegionName !== 'USA');
console.log(newArray);

Javascript to iterate through objects in array?

I'm trying to iterate through a large list of financial institutions (condensed from the 8974 objects to only 2 below) using javascript.
I want to save "id" and "name" in a new list. I'm a beginner at this and after trying some code in w3 website was unable to iterate through the different object capturing multiple "id"s and "name"s.
Anyone have an idea how to accomplish iterating through and capturing every
"id" and "name" in each json object within the json array?
{
"found": 8974,
"displaying": 8974,
"moreAvailable": false,
"createdDate": 1550566839,

Here we use a simnple map function to get desired array.

let eventsFiltered = events.map(
book => book.place.location.city);
console.log(eventsFiltered);
let city = 'Houston';
let eventsCt = events.filter(book => book.place.location.city == city);
console.log('2nd question');
console.log(eventsCt);
EDIT 2
i have a field named "parent" which is an array of string. i already
have a string named "12344" which is a part of array parent. how do i
check if the events.parent cotains this string and filter those
objects
let p = '1234';
let eventsF = events.filter(book => book.parent && Array.isArray(book.parent)&& book.parent.indexOf(p) !== -1);

Filter used for filter records with where conditions. In your case you want transform data and you just want a array of city from an array of object. So in this case use map instance of filter
Example
this.cityList = this.events.map(book => book.place.location.city);

How to get Parent keys in JSON

I have q requirement where I receive a JSON input and display it. Whenever I click on any value of the JSON, I need to get all parent keys in sequence.
Below is the sample JSON
{
"response": {
"Location": [{
"Name": "New York, NY",
"Point": {
"Latitude": "40.714550018310547",
"Longitude": "-74.007118225097656"
},
"BoundingBox": {
"SouthLatitude": "40.36376953125",
"WestLongitude": "-74.745925903320312",
"NorthLatitude": "41.056510925292969",
"EastLongitude": "-73.267219543457031"
},
"EntityType": "PopulatedPlace",
"Address": {
"AdminDistrict": "NY",
"CountryRegion": "United States",
"FormattedAddress": "New York, NY",
"Locality": "New York"
},
"Confidence": "High",
"MatchCode": "Good",
"GeocodePoint": {
"Latitude": "40.714550018310547",
"Longitude": "-74.007118225097656",
"CalculationMethod": "Rooftop",
"UsageType": "Display"
}
}, {
"Name": "New York, NY",
"Point": {
"Latitude": "40.714550018310547",
"Longitude": "-74.007118225097656"
},
"BoundingBox": {
"SouthLatitude": "40.36376953125",
"WestLongitude": "-74.745925903320312",
"NorthLatitude": "41.056510925292969",
"EastLongitude": "-73.267219543457031"
},
"EntityType": "PopulatedPlace",
"Address": {
"AdminDistrict": "NY",
"CountryRegion": "United States",
"FormattedAddress": "New York, NY",
"Locality": "New York"
},
"Confidence": "High",
"MatchCode": "Good",
"GeocodePoint": {
"Latitude": "40.714550018310547",
"Longitude": "-74.007118225097656",
"CalculationMethod": "Rooftop",
"UsageType": "Display"
}
}]
}
}
Now, I have this key chain in json response → Location → Point → Latitude. Suppose I have a key Latitude and I want all its parent keys in a sequence, how do I get that?
Note: This is a sample JSON. Keep in mind that I will get JSON dynamically.
