How to loop inside a json file with javascript? - javascript

I have a json file returned on my javascript code. The file looks like this :

I would like to loop inside the "data" and see how many different data elements exist(as you see each element has an id , from , name , description..) . How can i do that with javascript?

You can try the following code:
for(i=0;json.data.length;i++){
var element = json.data[i];
}
or also in this other way:
for (i in json.data) {
if (json.data.hasOwnProperty(i)) {
var element = json.data[i];
}
}

How can I take the data from choiceSet in adaptive cards

I want the data (i.e value inside choices array) inside the red choiseSet when selected and clicked on the btn, I kept an image and added action submit as action.submit as that's my usecase, I am pretty much confused how I can do that, Here's the card payload
{
"$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
"type": "AdaptiveCard",
"version": "1.2",
"body": [
{
"type": "Input.ChoiceSet",
"id": "myColor2",
"style": "expanded",
"value": "1",
"choices": [
{
"title": "Red",
"value": "1"
}
]
},
{
"type": "Image",
"altText": "it's a image",
"url": "https://media.istockphoto.com/vectors/bhutanese-ngultrum-btn-vector-id1304476894",

"height": "100px",
"horizontalAlignment": "Left",
"selectAction": {
"type": "Action.Submit",
"id": "btn",
"title": "btn"
}
}
]
}
Once submitted by clicking on the icon, the bot should receive an activity of type message but with no text. The data you want is in the value property.
{
"activity": {
"channelData": {
"postBack": true,
"clientActivityID": "<REMOVED>",

More efficient way to remove from an object attributes present in a group of objects

I'm manipulating some javascript objects and I want to know if is there a more efficient and easy way to process my data.
I already do that, but I'm a beginner in js.
I have four objects with this structure: basically there is an array of blocks and any object has a different number of blocks. In every block, in the features attribute, I have another array with some features.
Then I have another object, and I have to remove from this object (I call it structure) blocks and features that are not present in my four initial object.
This is a sample product object

Here i loop my initial objects (this.compare_products) to extract, in two arrays (featureGroupIds - featureIds) the ID of my block and the CategoryFeatureId
let featureGroupIds = []
let featureIds = []
this.compare_products.forEach((object) => {
featureGroupIds = featureGroupIds.concat(FeaturesGroups.map(o => o.ID))
featureIds = featureIds.concat(FeaturesGroups.map(o => o.Features.map(o => o. CategoryFeatureId))).flat(2)
})
The two arrays, featureGroupIds and featureIds are now filled with every block ID and every CategoryFeatureId present in my four object.
Now I have to filter the object I call "structure" to remove the block and the features with an ID that is not present in my arrays.
This is my structure, and as you can see is similar.
[
{
"name": "Display",
"data": {
"id": 34566,
"category_id": 2647
},
"features": [
{
"name": "Tipo di display",
"data": {
"id": 85325,
"category_id": 2647,
"feature_id": 9104,
"category_feature_group_id": 34566,

}
},
{

"category_id": 2647,

"category_feature_group_id": 34566,

}
},
{
"name": "Dimensioni schermo",
"data": {

"category_id": 2647,
"feature_id": 3544,
"category_feature_group_id": 34566,
"order": 100149
}
},
{
"name": "à di Pixel",
"data": {
"id": 85347,
"category_id": 2647,
"feature_id": 13246,
"category_feature_group_id": 34566,
"order": 100147
}
},
{
"name": "Tipo di vetro",
"data": {
"id": 94704,
"category_id": 2647,
"feature_id": 7610,
"category_feature_group_id": 34566,
"order": 100050
}
}
]
},
{
"name": "Altre caratteristiche",
"data": {
"id": 34569,
"category_id": 2647,
"feature_group_id": 146,
"name": null,
"order": 0
},
"features": [
{
"name": "inside",
"data": {
"id": 110410,
"category_id": 2647,
"feature_id": 18688,
"category_feature_group_id": 34569,
"order": 100000
}
}
]
}
]
Here is my function
structure = structure.filter(featureGroup => this.featureGroupIds.includes(featureGroup.data.id));
structure.map((object) => {
object.features.filter(feature => this.featureIds.includes(feature.data.feature_id))
})
this.featureIds and this.featureGroupIds are the array with the group IDS and with the feature IDS.
Is there a more efficient way to do this?

How can i sort array with objects which have property with another array of objects but not with ES6 [duplicate]

This question already has answers here:
Sort nested array of object in javascript
(4 answers)
Closed 3 years ago.
I have this kind of array with objects. In each object except properties i have another array with objects called "secondary_fields". I need to access the last element in the secondary_fields array (secondary_fields[3]) where i have value of when it is created and after that to sort all of the objects
by the date time based on the value inside for example "2020-01-13 17:42:51";
But not with ES6 because i am using old platform where the ES6 version of Java Script is not supported
let arr =
[

"display_field": "new best article",

},

},

You can make use of the array method's sort method and sort on display_value.
arr.sort(function(a, b) {
return new Date(a.secondary_fields[3].display_value) - new Date(b.secondary_fields[3].display_value)
})
Edit
Or I guess in your case,
return new Date(b.secondary_fields[3].display_value) - new Date(a.secondary_fields[3].display_value)
let arr =
[
{
"external": false,
"link": "--",

I need to pick up the all the names from the body, which are for example :
"Frami F407 (atk 34)", "Frami F144 (lasipalatsi 120)",
"Frami F211 (fysioterapia/teoria)", "Frami F410 (atk 34)
Here's how I process the data in order to get the names;
var jsonQuery = {
"startDate": startDate,
"endDate": endDate,
"building": [building]
};
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function () {
if (xhr.readyState == 4 && xhr.status == 200) {
var json = JSON.parse(xhr.responseText);
console.log(xhr.responseText);
var rooms = [];
for (var i = 0; i < json.reservations.length; i++) {
if (json.reservations[i].resources != null) {
for (var j = 0; j < json.reservations[i].resources.length; j++) {
var reservation = json.reservations[i];
var resource = json.reservations[i].resources[j];
if (resource.type === "room") {
if (rooms.indexOf("code")) {
rooms.push(resource.name);
}
}
}
}
}
}
};
xhr.open("POST", "URL", true, "API-key", "");
xhr.setRequestHeader('Content-Type', 'application/json');
xhr.send(JSON.stringify(jsonQuery));
This is how it should work : https://jsfiddle.net/p474djan/3/
But the problem is, when I run it through JSON.parse() and check in the console log, it keeps the first two names ("Frami F407 (atk 34)" and "Frami F144 (lasipalatsi 120)") but removes all the rest of the names. Any idea why this is happening?
I am not able to find any issue on your code but here it is my suggestion you can achieve the same via underscore.js without any looping and so on
https://jsfiddle.net/p474djan/5/
document.getElementById("pageOne").innerHTML = _.pluck(_.flatten(_.pluck(json["reservations"], 'resources')), 'name').join("<br/>")
Please have a look in to this

Nested Loops in angularjs

I have been using nested loops to access data of the json object to display the id and type of topping, however its not working. Here's my code:
var j_obj = {
"id": "0001",
"type": "donut",
"name": "Cake",
"ppu": 0.55,
"batters": {
"batter": [{
"id": "1001",
"type": "Regular"
}, {
"id": "1002",
"type": "Chocolate"
}, {
"id": "1003",
"type": "Blueberry"
}, {
"id": "1004",
"type": "Devil's Food"
}]
},
"topping": [{
"id": "5001",
"type": "None"
}, {
"id": "5002",
"type": "Glazed"
}, {
"id": "5005",
"type": "Sugar"
}, {
"id": "5007",
"type": "Powdered Sugar"
}, {
"id": "5006",
"type": "Chocolate with Sprinkles"
}, {
"id": "5003",
"type": "Chocolate"
}, {
"id": "5004",
"type": "Maple"
}]
}
var Outer_log=[];
debugger
angular.forEach(j_obj, function(an_object){
//Outer_log.push("ID : "+an_object.id+" type : "+an_object.type);
angular.forEach(an_object.topping,function(innerobject){
Outer_log.push("ID : "+innerobject.id+" type : "+innerobject.type);
},Outer_log);
});
console.log(Outer_log);
Could someone please highlight the error in above code, Thanks
Without using nested loop you can iterate using angular.forEach like this
var finalArray=[];
angular.forEach(j_obj[0].topping, function(eachobject){
finalArray.push("ID : "+ eachobject.id+" type : "+ eachobject.type);
});
Angulars forEach is intended to iterate over arrays not object. so if you change your code to something like this
var j_obj = [{ ...}] //object is wrapped inside array.
it will work. Another thing is you don't need a nested loop in this case. You can just do:
angular.forEach(j_obj.topping, function(key, value){ ... });
you are iterating over object where as loop run over array.
hope this helps JSfiddle link
