change value based on nested array value - javascript

I got a below object from the API
let response = {
"id": 301344576,
"quantity": 92,
"unlimited": false,
"inStock": true,
"name": "Virgin Coconut Oil",
"price": 328.47,
"isShippingRequired": true,
"weight": 0.5,
"url": "https://subhikshaf2c.company.site/Virgin-Coconut-Oil-p301344576",
"options": [
{
"type": "SELECT",
"name": "Weight",
"nameTranslated": {
"en": "Weight"
},
"choices": [
{
"text": "500 gm",
"textTranslated": {
"en": "500 gm"
},
"priceModifier": 0,
"priceModifierType": "ABSOLUTE"
},
{
"text": "1 kg",
"textTranslated": {
"en": "1 kg"
},
"priceModifier": 317.03,
"priceModifierType": "ABSOLUTE"
}
],
"defaultChoice": 0,
"required": false
}
],
"combinations": [
{
"id": 161026822,
"combinationNumber": 1,
"options": [
{
"name": "Weight",
"nameTranslated": {
"en": "Weight"
},
"value": "1 kg",
"valueTranslated": {
"en": "1 kg"
}
}
],
"sku": "OL002-001592-1kg",
"quantity": 36,
"inStock": true,
"unlimited": false,
"weight": 1,
"warningLimit": 20,
"attributes": [],
"defaultDisplayedPrice": 677.78,
"defaultDisplayedPriceFormatted": "₹677.78"
}
]
}
and the weight info of this. Suppose i got 1KG so i'm creating JSON like
{
"Id":301344576,
"weight":"1 kg",
"quantity":1
}
In another page again I'm calling the same API and need to create json format like
[
{
"stock": 92,
"quantity": 1,
"productId": 301344576,
"basePrice": 328.47,
"productPrice": 344.89,
"weight": "500 gm",
"productName": "Virgin Coconut Oil",
}
]
The problem is if the weight: '1KG' i need to look into the combinations and need to update the quantity. So my json will become like
{
"stock": 36,
"quantity": 1,
"productId": 301344576,
"basePrice": 645.5,
"productPrice": 344.89,
"weight": "1 kg",
"productName": "Virgin Coconut Oil",
}
for the basePrice, I'm doing price+priceModifier value of selected weight from the options.
How can i achieve the desired result.

How to get a specific object from whole object?

I am trying to get specific object from a whole object below is the example
by using localStorage.getItem('shop/elasticCache/shirt');
I get below data
{"description":"Tech Shirt","configurable_options":[{"attribute_id":80,"values":[{"value_index":"5176","label":"RUST"}],"label":"Color","attribute_code":"color"},{"attribute_id":125,"values":[{"value_index":"2898","label":"Small"},{"value_index":"2901","label":"Medium"},{"value_index":"2904","label":"Large"}],"label":"Size","attribute_code":"size"}],"tsk":1594790209,"size_options":[2898,2901,2904],"regular_price":28,"final_price":null,"price":28,"color_options":[5176],"special_from_date":null,"id":250659,"category":[{"category_id":2,"name":"Default Category","position":1},{"category_id":3,"name":"Clothing","position":14985},{"category_id":30,"name":"Bottoms","position":798},{"category_id":58,"name":"Leggings","position":1},{"category_id":1130,"name":"Char Test Category","position":30}],"sku":"S155551","product_links":[{"link_type":"related","linked_product_sku":null,"linked_product_type":null,"position":0,"sku":"P100031"},{"link_type":"related","linked_product_sku":null,"linked_product_type":null,"position":0,"sku":"P100031"}

You can iterate through the entire object and can get the required values. The above code gives the values of category from index 1.

How do I use Object.entries(...).forEach.every?

const value = Object.values(queryKeys);
const result = handleFilterModifier(

compareValue,

return result;

This operation fails when either of the queryModifiers has "equals" in its value pair. Anything else returns the actual true result. I don't understand why it fails on "equals".
I feel like there should be a forEach somewhere but I don't know where to put it and maybe there's something wrong with the code. I need help figuring it out.

I think you should replace this
const queryKeys = keys: {
price: '1000',
weight: '1000'
}
with
const queryKeys = {
price: '1000',
weight: '1000'
}
and replace this
const value = Object.values(queryKeys);
with
const value = queryKeys[filterKey];

I want now to find all products where one of the variants has the Height >= 1200 and Weight >= 500
In this example this should be My Product 1 and My Product 3. My Product 2 doesn't match as the Weight Property is below the criteria.
How can I do this. Is there a way. The data structure can be changed but only if really needed.

I follow your document and created 3 sample documents as below in my cosmos db :
[
{
"id": "1",
"name": "My Product 1",
"variants": [
{
"id": 2179,
"code": "A",
"attributes": {
"att_set_1": {
"en": {
"name": "Attribute Set 1",
"data": [
{
"id": 919,
"title": "Height",
"label": "height_mm",
"v": 2330,
"unit": "mm"
},
{
"id": 921,
"title": "Weight",
"label": "weight",
"v": 2931,
"unit": "kg"
},
{
"id": 923,
"title": "Other",
"label": "blah",
"v": 200,
"unit": "mm"
}
]
}
}
}
}
]
},
{
"id": "2",
"name": "My Product 2",
"variants": [
{
"id": 2180,
"code": "B",
"attributes": {
"att_set_1": {
"en": {
"name": "Attribute Set 1",
"data": [
{
"id": 919,
"title": "Height",
"label": "height_mm",
"v": 100,
"unit": "mm"
},
{
"id": 921,
"title": "Weight",
"label": "weight",
"v": 200,
"unit": "kg"
},
{
"id": 923,
"title": "Other",
"label": "blah",
"v": 200,
"unit": "mm"
}
]
}
}
}
}
]
},
{
"id": "3",
"name": "My Product 3",
"variants": [
{
"id": 2181,
"code": "C",
"attributes": {
"att_set_1": {
"en": {
"name": "Attribute Set 1",
"data": [
{
"id": 919,
"title": "Height",
"label": "height_mm",
"v": 2000,
"unit": "mm"
},
{
"id": 921,
"title": "Weight",
"label": "weight",
"v": 999,
"unit": "kg"
},
{
"id": 923,
"title": "Other",
"label": "blah",
"v": 200,
"unit": "mm"
}
]
}
}
}
}
]
}
]
Then I use the SQL ：
SELECT all FROM all join a in all.variants join b in
a.attributes.att_set_1.en.data where (b.title = 'Height' and b.v >=
2000) or (b.title = 'Weight' and b.v >= 1000)
Result data:
[

{
"id": 2179,
"code": "A",

"en": {
"name": "Attribute Set 1",
"data": [
{
"id": 919,
"title": "Height",
"label": "height_mm",

Please notice that the value column is a keyword and cannot be used in a document. So, in my documents I remove it with v.
Update Answer:
After a few attempts, it seems impossible to directly query the results you want from the the Cosmos DB via the SQL statement.
However , Cosmos DB provides us with Stored Procedure when we face complex queries. If you do not know much about stored procedure, you can read this article.
Please refer to the stored procedure I created as below :
function sample() {
var collection = getContext().getCollection();
var isAccepted = collection.queryDocuments(
collection.getSelfLink(),
'SELECT * FROM c',
function (err, feed, options) {
if (err) throw err;
var returnArray = [];
if (!feed || !feed.length){
getContext().getResponse().setBody('no docs found');
} else{
for(var i=0;i<feed.length;i++){
var foundHeight = false, foundWeight=false;
var dataArray = feed[i].variants[0].attributes.att_set_1.en.data;
for(var j=0;j<dataArray.length;j++){
var f = dataArray[j];
if((f.title=='Height'&&f.v>=2000){
foundHeight = true;
} else if(f.title=='Weight'&&f.v>=1000)){
foundWeight = true;
}
}
if(foundHeight && foundWeight)
returnArray.push(feed[i]);
}
}
getContext().getResponse().setBody(JSON.stringify(returnArray));
});
if (!isAccepted) throw new Error('The query was not accepted by the server.');
}
Output result :
[
{
"id": "1",
"name": "My Product 1",
"variants": [
{
"id": 2179,
"code": "A",
"attributes": {
"att_set_1": {

"unit": "kg"
},
{
"id": 923,
"title": "Other",
"label": "blah",
"v": 200,
"unit": "mm"
}
]
}
}
}
}
]
},
{

"label": "blah",
"v": 200,
"unit": "mm"
}
]
}
}
}
}
]
}

This result should be what you want. You can create it on portal or in your code. Any concern ,please let me know.
Hope it helps you.

Filter json object in JavaScript with a combination of Union and Intersection

const myJSON = {
"seller1": [
{
"product": "headphones",
"price": 23,
"weight": 1
},
{
"product": "earphone",
"price": 12,
"weight": 1
},
{
"product": "iPhone",
"price": 999,
"weight": 3
},
{
"product": "ipad",
"price": 399,
"weight": 4
}
],
"seller2": [
{
"product": "headphones",
"price": 25,
"weight": 1
},
{
"product": "earphone",
"price": 10,
"weight": 1
},
{
"product": "iPhone",
"price": 949,
"weight": 2
},
{
"product": "ipad",
"price": 449,
"weight": 3
}
]
}
I need to filter myJSON from a multi-select box where, if user selects product: iPhone and product: headphones, I need to display all the products that matches iPhone and headphones. In this case, myJSON will be
const myJSON = {
"seller1": [
{
"product": "headphones",
"price": 23,
"weight": 1
},
{
"product": "iPhone",
"price": 999,
"weight": 3
}
],
"seller2": [
{
"product": "headphones",
"price": 25,
"weight": 1
},
{
"product": "iPhone",
"price": 949,
"weight": 2
},
]
}
Now if the user selects different key, price: 449, myJSON should now be empty coz there is not property price: 449 in that anymore. But, if price: 23 then,
const myJSON = {
"seller1": [
{
"product": "headphones",
"price": 23,
"weight": 1
}
]
}
So for example, if user selects 3 items with same key(product), the we should show all the three items that match these 3 items from original json. Now when he selects a different key(price), then we should only filter from the previous result.
Any suggestion on how to implement this is much appreciated.

How to return a childobject from json with lodash?

Suppose I have the following json file and I would like to return the 'existing.primaryBundle.products' array preferrably with lodash:
{
"existing": {
"hasPlatinum": false,
"primaryBundle": {
"id": "2008",
"name": "TV - Entertainment, Sport",
"products": [
{
"name": "Entertainment",
"id": "100",
"price": 2600,
"gifted": false
},
{
"name": "Sport",
"id": "107",
"price": 2500,
"gifted": false,
"swappableProducts": [
{
"name": "Movies",
"id": "105",
"price": 2000,
"gifted": false
}
]
}
]
},
"extrasBundle": {
"id": "131",
"name": "Optional Extras - MUTV (Sports), LFCTV (Sports), Chelsea TV (Sports)",
"products": [
{
"name": "MUTV (Sports)",
"id": "665",
"price": 0,
"gifted": false
},
{
"name": "LFCTV (Sports)",
"id": "666",
"price": 0,
"gifted": false
},
{
"name": "Chelsea TV (Sports)",
"id": "667",
"price": 0,
"gifted": false
}
]
}
}
}
I have tried lodash and use this statement:
list2 = _.pick(existing,'primaryBundle.products')
But this returns an error and not the wanted result. How can I select this products array?

you could use _.get(nameOfObject, 'existing.primaryBundle.products') of course you would need to name your object like I've done below with sampleObject;
check out the lodash docs too
const sampleObject = {
"existing": {
"hasPlatinum": false,
"primaryBundle": {
"id": "2008",
"name": "TV - Entertainment, Sport",
"products": [{
"name": "Entertainment",
"id": "100",
"price": 2600,
"gifted": false
}, {
"name": "Sport",
"id": "107",
"price": 2500,
"gifted": false,
"swappableProducts": [{
"name": "Movies",
"id": "105",
"price": 2000,
"gifted": false
}]
}]
},
"extrasBundle": {
"id": "131",
"name": "Optional Extras - MUTV (Sports), LFCTV (Sports), Chelsea TV (Sports)",
"products": [{
"name": "MUTV (Sports)",
"id": "665",
"price": 0,
"gifted": false
}, {
"name": "LFCTV (Sports)",
"id": "666",
"price": 0,
"gifted": false
}, {
"name": "Chelsea TV (Sports)",
"id": "667",
"price": 0,
"gifted": false
}]
}
}
}
console.log(_.get(sampleObject, 'existing.primaryBundle.products'));

The main reason why it returns an error is because existing is not a global scoped object, you have to assign object to some variable like const obj = {...} and then pass the parameter to _pick method as obj.existing, yet I don't see a reason to use lodash in here, you can just reference the path to that object directly.
