I have a system that makes JSON responses like this. This is a list to use in a table. I have never seen this way of writing the field names first and then the data in another set?
Is this way of writing JSON data called something special?
I cannot figure how to read the response in my javascript/jQuery, does anyone have an example or google hint?
(anyone know if "jtable" can read it?)

I've been playing around trying to learn in an API project using Postman and conducting tests using JavaScript. So far, I have succeeded with the help of reading on websites and watching YouTube videos. Of course, previous tests and playing around have been fairly easy but now I came to a stop. I really tried to figure this out for several weeks but I need further guidance, a push in the right direction or direct help.
What I'm trying to do is to filter out some of the response to only view objects that contain specific data.
To do that, I'm using a filter where I want all products containing a specific value inside an array "product_option_values".
My first approach was to see if I could sort products having any values from the first array, and it worked. It filters just fine.
var filterSmall = jsonData.products.filter(fs => fs.associations.product_option_values);
My next approach was to get to my goal of filtering out products according to specific values inside this array. I tried many simple .(dot) combinations and pointing to [index] to access it without any luck. (I must add that I know how to access this from a specific product, but that way doesn't work when filtering).
I've also tried other approaches such as:
var filterSmall = jsonData.products.filter(fs => fs.associations["product_option_values", 0, "name"] === "S");
and other similar combinations.
This is a very shortened sample of the structure of "products" which in its full form consists of 20 products and far more values inside of it:
{
"products": [
{
"id": 16,
"manufacturer_name": "Graphic Corner",
"quantity": "0",
"price": "12.900000",
"indexed": "1",
"name": "Mountain fox notebook",
"associations": {
"categories": [
{
"id": "2"
},
{
"id": "6"
}
],
"product_option_values": [
{
"id": "22"
},
{
"id": "23"
}
]
}
},
{
"id": 17,
"manufacturer_name": "Graphic Corner",
"quantity": "0",
"price": "12.900000",
"indexed": "1",
"name": "Brown bear notebook",
"associations": {
"categories": [
{
"id": "2"
},
{
"id": "6"
}
],
"product_option_values": [
{
"id": "23"
},
{
"id": "24"
}
]
}
}
]
}
and here is a small and expanded sample from product_option_values:
{
"product_option_values": [
{
"id": 1,
"id_attribute_group": "1",
"color": "",
"position": "0",
"name": "S"
},
{
"id": 2,
"id_attribute_group": "1",
"color": "",
"position": "1",
"name": "M"
},
{
"id": 3,
"id_attribute_group": "1",
"color": "",
"position": "2",
"name": "L"
}
]
}
How do I proceed? Did I do anything correct or even close to it?
Perhaps I've been staring at this for too long.
Thanks in advance.
If you want to compare nested attributes you have to transform the objects (e.g. by using a map operation), so that the relevant attributes are easily accessible for a comparison. If you want to filter by product_option_value id, you could do something like this:
const jsonData = {
"products": [
{
"id": 16,
"manufacturer_name": "Graphic Corner",
"quantity": "0",
"price": "12.900000",
"indexed": "1",
"name": "Mountain fox notebook",
"associations": {
"categories": [
{
"id": "2"
},
{
"id": "6"
}
],
"product_option_values": [
{
"id": "22"
},
{
"id": "23"
}
]
}
},
{
"id": 17,
"manufacturer_name": "Graphic Corner",
"quantity": "0",
"price": "12.900000",
"indexed": "1",
"name": "Brown bear notebook",
"associations": {
"categories": [
{
"id": "2"
},
{
"id": "6"
}
],
"product_option_values": [
{
"id": "23"
},
{
"id": "24"
}
]
}
}
]
};
const sample = {
"product_option_values": [
{
"id": 22,
"id_attribute_group": "1",
"color": "",
"position": "0",
"name": "S"
},
{
"id": 2,
"id_attribute_group": "1",
"color": "",
"position": "1",
"name": "M"
},
{
"id": 3,
"id_attribute_group": "1",
"color": "",
"position": "2",
"name": "L"
}
]
};
const ids = sample.product_option_values.map((el) => String(el.id));
console.log(ids);
const filtered = jsonData.products.filter((fs) => fs.associations.product_option_values.map((e) => e.id).some((f) => ids.includes(f)));
console.log(filtered);
I have the following array of objects.
I want to search the word Powai (case insensitive). But when I search the word I am not getting the results with the word (Powai) with parenthesis. I have attached the code below the JSON. Please help.
I am using https://github.com/kentcdodds/match-sorter this library along with the <Autocomplete /> component of Material-UI react to filter the results based on the input query.
[
{
"id": 31,
"name": "Powai",
},
{
"id": 3474,
"name": "Powai Chowk Mulund",
},
{
"id": 3475,
"name": "Powai Vihar Complex",
},
{
"id": 2428,
"name": "Forest Club Powai",
},
{
"id": 2635,
"name": "Hiranandani Powai Bus Station",
},
{
"id": 3561,
"name": "Ramda Hotel (Powai)",
},
{
"id": 2244,
"name": "Crisil House (Powai)",
},
{
"id": 2662,
"name": "I.R.B.Complex(Powai)",
},
{
"id": 2890,
"name": "Kingston Sez (Powai)",
},
{
"id": 3972,
"name": "Tatapower Centre (Powai)",
},
{
"id": 2362,

match-sorter version: ^4.1.0
node version: 12.14.0
npm (or yarn) version: 6.14.4
Relevant code or config
matchSorter(options, inputValue, {
keys: ["name"],
threshold: rankings.WORD_STARTS_WITH,
keepDiacritics: true,
});
I fixed the issue by changing the threshold value to threshold: rankings.CONTAINS.
That solved my problem.
As an example - I've included a one element array that contains an object that has a Children key, which is an array of objects and each object also has its' own Children key that contains another array.
[
{
"Id": "1",
"Children": [
{
"Id": "2",
"Children": [
{
"Id": "10",
"DisplayName": "3-4",
},
{
"Id": "1000",
"DisplayName": "5-6",
},
{
"Id": "100",
"DisplayName": "1-2",
},
]
}
]
}
]
There is a second array of objects that I would like to compare the first array of objects to, with the intention of making sure that the first array is in the same order as the second array of objects, and if it is not - then sort until it is.
Here is the second array:
[
{
"Id": "1",
"Children": [
{
"Id": "2",
"Children": [
{
"Id": "100",
"DisplayName": "1-2",
},
{
"Id": "10",
"DisplayName": "3-4",
},
{
"Id": "1000",
"DisplayName": "5-6",
},
]
}
]
}
]
The data that this will run on can be up in the tens of thousands - so performance is paramount.
What I'm currently attempting is using a utility method to convert each element of the second array into a keyed object of objects e.g.
{
1: {
"Id": "1",
"Children": [
{
"Id": "2",
"Children": [
{
"Id": "4",
"DisplayName": "3-4",
},
{
"Id": "3",
"DisplayName": "1-2",
},
]
}
]
}
}
This allows fast look up from the top level. I'm wondering if I should continue doing this all the way down or if there is an idiomatic way to accomplish this. I considered recursion as well.
The order of the already sorted array is not based on Id - it is arbitrary. So the order needs to be preserved regardless.
Assuming same depth and all Id's exist in each level of each object use a recursive function that matches using Array#findIndex() in sort callback
function sortChildren(main, other) {
other.forEach((o, i) => {
if (o.children) {
const mChilds = main[i].children, oChilds = o.children;
oChilds.sort((a, b) => {
return mChilds.findIndex(main => main.Id === a.Id) - mChilds.findIndex(main => main.Id === b.Id)
});
// call function again on this level passing appropriate children arrays in
sortChildren(mChilds, oChilds)
}
})
}
sortChildren(data, newData);
console.log(JSON.stringify(newData, null, ' '))
<script>
var data = [{
"Id": "1",
"Children": [{
"Id": "2",
"Children": [{
"Id": "3",
"DisplayName": "1-2",
},
{
"Id": "4",
"DisplayName": "3-4",
},
]
}]
}]
var newData = [{
"Id": "1",
"Children": [{
"Id": "2",
"Children": [{
"Id": "4",
"DisplayName": "3-4",
},
{
"Id": "3",
"DisplayName": "1-2",
},
]
}]
}]
</script>
I have 2 JSON files:
A Template JSON
A JSON output (from awscli)

I want to copy the values of the Keys in the original JSON file to the template file.
For example, KeyName is a common key between the 2 JSON files. The corresponding value tempKey is replaced in the template file.
The main use case of this is: I am trying to migrate a number of servers on AWS from 1 region to another. This is a part of migration process which will remove tons of manual clicking and configuration on AWS Console.
Note: I use BASH command line.
There's a way to do this with jq but it doesn't take a JSON template as input.
You'll have to modify it to become a query. This isn't the actual query you need, but something to get you started:
cat temp.json | jq '.Reservations[].Instances[] | { DryRun, ImageId, KeyName, SecurityGroups, InstanceType, Monitoring }'
Where temp.json is your output above that I placed into a file. For regular commands, just do something like aws ec2 describe-instances | jq ...
The output that gives me (keep in mind the restricted set I queried for) is:
{
"DryRun": null,
"ImageId": "ami-1234abcd",
"KeyName": "tempKey",
"SecurityGroups": [
{
"GroupName": "somegroup1",
"GroupId": "sg-ZZZZZ"
},
{
"GroupName": "somegroup2",
"GroupId": "sg-YYYYY"
}
],
"InstanceType": "t2.medium",
"Monitoring": {
"State": "disabled"
}
}
Hope this helps.
Basically I want to be able, in Javascript (JQuery optionally), to search into a JSON with nested elements for a particular element and edit it.
Ex. search for "components" with id 110 and change the name to "video card".
Notice the following JSON is just an example. I am wondering if javascript libraries or good tricks exist to do such a thing, I don't think traversing the whole json or writing my own methods is the best solution.
{
"computers": [
{
"id": 10,
"components": [
{
"id": 56,
"name": "processor"
},
{
"id": 24,
"name": "ram"
}
]
},
{
"id": 11,
"components": [
{
"id": 110,
"name": "graphic card"
},
{
"id": 322,
"name": "motherboard"
}
]
}
]
}
You could try linq.js.
You can use this javascript lib, DefiantJS (http://defiantjs.com), with which you can filter matches using XPath on JSON structures. To put it in JS code:
var data = {
"computers": [
{
"id": 10,
"components": [
{ "id": 56, "name": "processor" },
{ "id": 24, "name": "ram" }
]
},
{
"id": 11,
"components": [
{ "id": 110, "name": "graphic card" },
{ "id": 322, "name": "motherboard" }
]
}
]
},
res = JSON.search( data, '//components[id=110]' );
res[0].name = 'video card';
Here is a working fiddle;
http://jsfiddle.net/g8fZw/
DefiantJS extends the global object JSON with the method "search" and returns an array with matches (empty array if no matches were found). You can try out the lib and XPath queries using the XPath Evaluator here:
