Retreiving specific data from JSON repsonse only in certain array indexes

Hey sorry if this has been asked before, I haven't found an answer that has helped me.
I am working on building a personal application using the free Ticketmaster application but I'm having trouble with the JSON response.
An example of the response is:
data: {
classifications: [
type: {
id: 1,
name: "Dont want this"
}
],
[
type: {
id: 2,
name: "Dont want this"
}
],
[
category: {
id: 3,
name: "Food & Drink"
}
],
[
category: {
id: 4,
name: "Music"
]
}
I am trying to retrieve category names such as "Family", "Food & Drink", "Music" etc but only at some indexes does the array have category objects, the others have type.
Can someone tell me how to go through this array and only get the name when it is at category.name?
Any help is appreciated :)

Accessing Key Value Pair in JSON data results

I haven't needed to access JSON data so I'm a bit stumped. I've validated the data using a JSON formatter and it is valid so I know that is good.
All I'm trying to do is retrieve the data and populate a select box (specifically x-editable).
In there example, they provide:
$('#id').editable({
source: [
{value: 1, text: 'Male'},
{value: 2, text: 'Female'}
]
});
Yes, I could throw the 50 states in there but I'd like to use this same approach for other select boxes I plan on implementing.
Here is the datafeed I'm currently getting back from my JSON call:
{
"data": [{
"stateID": 1,
"stateAbbr": "AL",
"state": "Alabama"
}, {
"stateID": 2,
"stateAbbr": "AK",
"state": "Alaska"
}, {
"stateID": 3,
"stateAbbr": "AZ",
"state": "Arizona"
}, {
"stateID": 51,
"stateAbbr": "WY",
"state": "Wyoming"
}]}
My function snippet that I'm working with is:
$.getJSON("test.html?format=json",function(data){
statesArr = statesArr.concat(data);
});
Ideally, I'd like to make the statesArr look like this:
source: [
{value: 1, text: 'Alabama'},
{value: 2, text: 'Alaska'},
...
{value:50, text: 'Wyoming'}
]
But I'm at a loss on what to do from here. The format of the data feed, {"data is throwing me off. I'm used to getting data pretty much like X-Editable is looking for.

I am assuming here that resp is the response. And resp has data property. If I have misunderstood you, please tell me so.
var statesArr;
$.getJSON('test.html?format=json', function(resp){
statesArr = resp.data.map(function(state){
return {
value: state.stateID,
text: state.state
}
});
});
/* somewhere else later; make sure that statesArr is set */
$('#id').editable({
source: statesArr
});

How should I do an aggregate?

I have an array with products(objects) inside. It looks like:
[
{_id: 123, name:'first', category:'Vape', property:[
{key:'brand', values:'Eleaf'},
{key:'mechmode', values:'some'},
{key:'color', values:['red', 'blue']},
{key:'batrtype', values:'some2'},
]},
{_id: 1234, name:'second', category:'Vape1', property:[
{key:'brand', values:'Eleaf1'},
{key:'mechmode', values:'some'},
{key:'color', values:['black']},
{key:'batrtype', values:'some2'}
]},
{_id: 12345, name:'third', category:'Vape3', property:[
{key:'brand', values:'Eleaf3'},
{key:'mechmode', values:'some'},
{key:'color', values:['green', 'yellow']},
{key:'batrtype', values:'some2'}
]},
{_id: 123456, name:'fourth', category:'Vape', property:[
{key:'brand', values:'Eleaf'},
{key:'mechmode', values:'some'},
{key:'color', values:['red', 'green']},
{key:'batrtype', values:'some2'}
]}
]
Request from client
{category:'Vape', body:{brand:'Eleaf', color:'red'}}
How should I do an aggregate in mongo to get products which have brand = 'Eleaf'
and color = red in according to request?
Can somebody help please?

bgraham's answer is exactly right if you are using find. To do the same thing in an aggregation pipeline, use $match, such as:
db.aggregate([{$match:{
category: "Vape",
$and: [
{ property: { $elemMatch: { key: "brand", value: "Eleaf" },
{ property: { $elemMatch: { key: "color", value: "red" }
]
}}])
You could then add to the array any additional pipeline stages you need.

I think this should do the trick:
db.products.find({
category: "Vape",
$and: [
{ property: { $elemMatch: { key: "brand", value: "Eleaf1" },
{ property: { $elemMatch: { key: "color", value: "red" }
]})
I'm not sure the structure of your data is best practice. It might be easier if they were fields called "brand" with a value of "color" instead of key/value pairs.

How to get array from json footable

I'm trying to get the data with json to generate a footable table with pagination but it's not working.
my code actualy look like this.
sorry my bad english.
my index.json is returning it
{
Cartas: [
{
id: 3,
user_id: 1,
status: "2",
banco_cartas: null,
nome: "teste",
contrato: "",
grupo: "430",
cota: "3332",
credito_atual: 154371.02,
prazo_original: "",
prazo_atual: "126",
valor_parcela: "0",
pc_pago: 1,
pc_fc: 0,
valor_pago: 154371.02,
saldo_devedor: null,
taxa: 0,
data_compra: "2003-03-28T00:00:00+00:00",
created: "2017-06-22T17:39:23-03:00",
data_contemplacao: "2016-12-20T00:00:00+00:00",
data_entrega: null
},
{
id: 4,
user_id: 1,
status: "2",
banco_cartas: null,
nome: "CAS REP comerciais",
contrato: "",
grupo: "240",
cota: "320",
my jquery to load the json in footable
jQuery(function($){
$('#custom-ui-example').footable({
"columns": [
{ name: "nome",
title: "Nome"},
{ name: "credito_atual",
title: "Crédito Atual"},
{ name: "status",
title: "Status"}
],
"rows": $.get("index.json")
})};
my html
<table class="table" id="custom-ui-example" data-paging="true"></table>

Index.json should return array of objects, in your case it is returning object.
The format of the json should be
[{'id': '3'},{'id': '4'}]
Pagination seems to work fine.
Find the working fiddle here: https://jsfiddle.net/qwwjs7j3/

first of all, you should check if your json is valid. you can do that here for example: https://jsonformatter.curiousconcept.com/
then you can should make the get-call using:
$.get({
url: 'index.json'
}).done(function(data) {
data = JSON.parse(data);
});
the return data is hold in the data object of the callback function.
