How To Add A String Inside An Object For The Given Example

Hi iam finding the best way to add a string inside the given object.Any help would be appreciated
my String is 'created'
Down Below Is My Data
{
"id": "222",
"list": [
{
"name": "Tony",
}
],
iam trying to insert 'created' in the data like this
{
"id": "222",
"list": [
{
"name": "Tony",
"type":"created"
}
]

The string you've provided looks a lot like JSON data. You can convert a JSON string to an actual javascript object by using the JSON.parse(string) method.
With this object we then can query it's list property - which in your case is an array of objects - and add a new property type to each of the arrays elements. The final step is converting the object back to a JSON string using the JSON.stringify(object) method.
Here's an example:
let str = `{
"id": "222",
"list": [
{
"name": "Tony"
}
]
}`;
let data = JSON.parse(str);
data.list.forEach(element => {
element.type = "created";
});
str = JSON.stringify(data);
console.log(str);

const myObj = {
"id": "222",
"list": [
{
"name": "Tony",
}
],
};
myObj.list[0].type = "created";
This is the way you can do this. But you'd better use secified index of list items;
const index = 0; // Or any other way to get this
myObj.list[index].type = "created";

How can I go about replacing a number array inside a json string in SQL?

The data in SQL contains a lengthy JSON string in a cell similar to this:
{
"Name": "Example",
"Results": [
{
"ResultId": 0,
"AnswerIds": "[1,2,33,4,5]"
},
{
"ResultId": 1,
"AnswerIds": "[2,3,4,55,6]"
}
]
}
I have a list of replacement AnswerIds: Replace all 2 with 7, all 3's with 8's
How can I go about making a script for this?
I'm able to isolate the AnswerIds using crossapply and JSON_Query, but not sure how to go about replacing several changes in one array.

const json = {
"Name": "Example",
"Results": [
{
"ResultId": 0,
"AnswerIds": "[1,2,33,4,5]"
},
{
"ResultId": 1,
"AnswerIds": "[2,3,4,55,6]"
}
]
}
json.Results.forEach((itm, index)=> {
const arr = JSON.parse(itm.AnswerIds);
const replacedArray = arr.map(num=>{
if(num === 2) return 7;
if(num === 3) return 8;
return num;
});
json.Results[index].AnswerIds = JSON.stringify(replacedArray);
})
console.log(json);
This is what I have done, Take the json.Results array and iterate it with a forEach loop.
You can then access the AnswerIds object of each result.
Since the AnswerIds value is a string, we first convert it to an array.
Then we loop throught that array using a map, and do the replacements.
You might want to read up on JS maps, and JS foreach, JSON.parse, JSON.stringify

SQL Server 2016 has JSON support but you did not specify your SQL version.
Using DelimitedSplit8k you can do this:
-- SAMPLE STRING
DECLARE #string VARCHAR(1000) =
'{
"Name": "Example",
"Results": [
{
"ResultId": 0,
"AnswerIds": "[1,2,33,4,5]"
},
{
"ResultId": 1,
"AnswerIds": "[2,3,4,55,6]"
}
]
}';
-- SOLUTION
SELECT NewJSON =
(
SELECT
IIF(i.pos = 0,IIF(i.pos>0 AND sub.string IN(2,3), x.x, sub.string),
IIF(s2.ItemNumber=1,'"[','')+IIF(i.pos>0 AND sub.string IN(2,3),x.x,sub.string)) +
IIF(s2.ItemNumber>LEAD(s2.ItemNumber,1) OVER (ORDER BY s.ItemNumber,s2.ItemNumber),']"',
IIF(i.pos = 0,'',','))
FROM dbo.delimitedsplit8k(REPLACE(#string,CHAR(13),''),CHAR(10)) AS s
CROSS APPLY (VALUES(CHARINDEX('"AnswerIds": "',s.item))) AS i(pos)
CROSS APPLY (VALUES(SUBSTRING(s.item, i.pos+14, 8000))) AS ss(item)
CROSS APPLY dbo.delimitedsplit8k(ss.item,IIF(i.pos=0,CHAR(0),',')) AS s2
CROSS APPLY (VALUES(IIF(i.pos=0,s.item,
REPLACE(REPLACE(s2.item,']"',''),'[','')))) AS sub(string)
CROSS APPLY (VALUES(REPLACE(REPLACE(sub.string,'2',7),'3',8))) AS x(x)
ORDER BY s.ItemNumber, s2.ItemNumber
FOR XML PATH('')
);
Returns:
{
"Name": "Example",
"Results": [
{
"ResultId": 0,
"AnswerIds": "[1,7,33,4,5]"
},
{
"ResultId": 1,
"AnswerIds": "[7,8,4,55,6]"
}
]
}

node.js transform xml into json with xml2js

I am using the node.js package xml2js to transform xml into json.
Documentation is here: https://www.npmjs.com/package/xml2js
My problem is that attributes for those xml are not correctly transformed.
example XML with multiple events
<events><event id="E0-001-098932239-8"></event><event id="E0-001-105389601-2"></event><event id="E0-001-104342965-3"></event><event id="E0-001-104830349-3"></event><event id="E0-001-105374979-6"></event><event id="E0-001-105389620-7"></event><event id="E0-001-104247759-2"></event><event id="E0-001-104342949-5">
Result from JSON.stringify(result.search.events)
The event tag is only once in the generated JSON - My expectation is that it should have multiple tags event. So I assume the transformation process went wrong. I tried multiple options for the parser like ignoreAttrs, explicitArray or explicitChildren but without success.
[{
"event": [{
"$": {
"id": "E0-001-098932239-8"
},
]
}, {
"$": {
"id": "E0-001-105389601-2"
},
}, {
"$": {
"id": "E0-001-104342965-3"
},
}, {
"$": {
"id": "E0-001-104830349-3"
},
access JSON elements
After correct transformation I expect to simply access the JSON elements via event[1].$.id
but all tries are unsuccessful:
events.event --> undefined
events.event.$ --> undefined
events.$ --> undefined
My Question is now: how can i correctly transform the xml into JSON and access the elements correctly?

Javascript is starting from 0, you should get events[0].event[0].$.id
Also, you can try with another package (camaro) with simply and easily change the desired result.
Example:
const xml = '<events><event id="E0-001-098932239-8"></event><event id="E0-001-105389601-2"></event><event id="E0-001-104342965-3"></event><event id="E0-001-104830349-3"></event><event id="E0-001-105374979-6"></event><event id="E0-001-105389620-7"></event><event id="E0-001-104247759-2"></event><event id="E0-001-104342949-5"></event></events>'
const temp = {
events: ['/events/event', {
id: '#id'
}]
}
const transform = require('camaro')
const results = transform(xml, temp)
console.log(JSON.stringify(results, null, 2))
Results
{
"events": [
{
"id": "E0-001-098932239-8"
},
{
"id": "E0-001-105389601-2"
},
{
"id": "E0-001-104342965-3"
},
{
"id": "E0-001-104830349-3"
},
{
"id": "E0-001-105374979-6"
},
{
"id": "E0-001-105389620-7"
},
{
"id": "E0-001-104247759-2"
},
{
"id": "E0-001-104342949-5"
}
]
}

Create nested JSON array

I'm trying to create a JSON array to send it to my web service. This is how my json should look like:
[{
"tipus": 1,
"proveidor": 3,
"atributs": {
"atribut":{
"id": 1,
"valor": 8
},
"atribut":{
"id": 2,
"valor": 500
}
}
}]
So, I have two general values "tipus" and "proveidor" and multiple "atributs" each "atribut" is composed with "id" and "valor".
When I construct the json I get this instead of what I want:
[
2:{
"tipus": 1,
"proveidor": 3,
1:{
"id": 1,
"valor": 8
},
0:{
"id": 2,
"valor": 500
}
}]
This is how I'm building the json:
// For every founded in $scope.atrb i need to create an 'atribut' element into my json
$scope.a = [];
var key;
for(key in $scope.atrb){
var newField = {
"idatributs_actiu": $scope.atrb[key].idatributs_actiu,
"nomAtribut": $scope.atrb[key].nomAtribut,
"valor": $scope.atrb[key].valor,
"idActiu": $routeParams.idTipusActiu,
"value": "",
"ordre": $scope.atrb[key].ordre,
"idatributs_generics": $scope.atrb[key].idatributs_generics
};
$scope.a.push(newField);
}
$scope.f = $scope.a;
});
var generics = {
"nom": $scope.nom,
"tipus": $routeParams.idTipusActiu,
"proveidor": $scope.proveidor.id
};
$scope.a.push(generics);
It's my first project with angular and I'm not sure if I'm building the json appropriately, basically i use an array to build a json but I don't know how to nested it 'atribut' inside 'atributs'.
The main idea is to read the 'generics' atributes and then loop through 'atributs' and read all 'atribut' element getting the properties.
Regards

Like S4beR and Kevin B told me, I just need to do an JS array. This is in my controller:
var obj = { generics: g, atributs: $scope.a };
g: it's an object with the generic properties
$scope.a: this is an array with 'atribut' objects which contais all
the properties I need save to.

Angular bind to filtered count

I have this array:
[
{
type: "hhh",
items: [
{
"name": "EGFR",
"type": "a",
"selected": true
}
]
},
{
type: "aaa",
items: [
{
"name": "mm",
"type": "b",
"selected": false
}
]
},
{
type: "ii",
items: [
{
"name": "pp",
"type": "bb",
"selected": true
}
]
}
]
I want to show a counter of the items with selected property "true".
I want it to be changed real time when change.
(Without watch and function)
Thnaks!

Here is the way:
var current_selected = {
get amount(){
var res = 0;
arr.forEach(function(item, i, arr) {
if (item.items[0].selected) res++;
})
return res;
}
}
Calling:
current_selected.amount
Fiddle

You can use JsonPath to get the count. Also using JsonPath has an added advantage of working on complex json structure. For the example you gave, you just need to include jsonpath js file and use the following in your script:
console.log(arr);
var filtered = jsonPath(arr, "$.[*].items[?(#.selected==true)]");
console.log(filtered);
console.log(filtered.length);
where arr is your json structure.
JsonPath can be got from :
