We Keep Coding

is it possible to retrieve and print the data from a json object inside json array without using any index values and specific keys

[
{
"id": "628ba44f5a6de600071d16fa",
"#baseType": "LogicalResource",
"isBundle": false,
"isMNP": false,
"businessType": [],
"category": [
{
"id": "628ba3ef5a6de600071d165f",
"name": "Starterpack2",
"description": "Starterpack2",
"code": "RC17",
"version": 2
}}]
now i need to check and print the JSON Object inside the JSON Array if category is present then it should print and in future if category is changed according to that if we pass parameter the output should print we don't hard code the code
i have tried by using key values it is coming but if the key value changes it is not printing the object
EX:-
[
{
"id": "628ba44f5a6de600071d16fa",
"#baseType": "LogicalResource",
"isBundle": false,
"isMNP": false,
"businessType": [],
"category": [
{
"id": "628ba3ef5a6de600071d165f",
"name": "Starterpack2",
"description": "Starterpack2",
"code": "RC17",
"version": 2
}}]
in the above code i have printed category object but if category changed to categories it is not printing so i want a code which can read the code and based on parameters user giving it should be print the output

Try this.
For Example:
let a = [{"id": "628ba44f5a6de600071d16fa","category": [
{
"id": "628ba3ef5a6de600071d165f",
"name": "Starterpack2",
"description": "Starterpack2",
"code": "RC17",
"version": 2
}]}]
function print (values){return (a[0][`${values}`])}
//now just pass any name like "category" or in future "categories"
print("category") //this will retrun the array.
Now modify with your requirements.

It seems you want to get the value of the key(that can be parameterized).
const jsonArray = [
{
"id": "628ba44f5a6de600071d16fa",
"#baseType": "LogicalResource",
"isBundle": false,
"isMNP": false,
"businessType": [],
"category": [
{
"id": "628ba3ef5a6de600071d165f",
"name": "Starterpack2",
"description": "Starterpack2",
"code": "RC17",
"version": 2
}
]
}
];
const parameter = "category";
const result = jsonArray.find(({ [parameter]: value }) => value);
if (result) {
console.log(result);
} else {
console.log(`No object found with ${parameter}`);
}
If this is not what you are looking for, then please add your code snippet for better understanding.

How can I store mapping orders in BBDD and then eval them

I'm trying to store in MongoDB one document with an object with the properties I want to map latter. My idea it's to create a function that will receive 2 params. First the object where I got to find the mapping, and second the object where I have to take the info from.
For example I want to store this JSON (that would be the first parameter in the function):
{
"name": "client.firstName",
"surname": "client.surname",
"age": "client.age",
"skills": [
{
"skillName": "client.skills[index].name",
"level": "client.skills[index].levelNumber",
"categories": [
{
"categoryName": "client.skills[index].categories[index].name",
"isImportant": "client.skills[index].categories[index].important"
}
]
}
]
}
And the second paramenter would be something like this (it's the object where you find the information.
{
"client": {
"firstName": "Jake",
"surname": "Long",
"age": 20,
"skills": [
{
"name": "Fly",
"level": 102,
"categories": [
{
"name": "air",
"important": true
},
{
"name": "superpower",
"important": false
}
]
},
{
"name": "FastSpeed",
"level": 163,
"categories": [
{
"name": "superpower",
"important": false
}
]
}
]
}
}
The idea it's: with de paths that I have in the first object, find it in the second one.. The problem I found it's when I have arrays, because when I defined the mapping rules I don't know how many positions will have the array I want to map. So in the mapping object (first) I'll only define the path but I'll not put it with the same lenght of the secondone because I don't know how much it will have.

Merge geojson based on unique ID

I'm a beginner in Javascript so please exuse this probably dumb question. I want to merge two json files based on unique object id.
Number one look like this:
"features": [{
"id": "3876802",
"properties": {
"name": "some name",
"facts": "some facts"}},
{"id": "3876803",
"properties": {"name":"another name"...}}...]
Number Two looks like this:
"features": [{
"id": "3876803",
"properties": {
"description": "some description",
"website": "afancywebsite"}},
{"id": "3876803",
"properties": {...}}]
The Elements in the second Json are not in the same order and not all elements of the first file exist in the second.
The Result should look like this:
"features": [{
"id": "3876802",
"properties": {
"name": "some name",
"facts": "some facts"}},{
"id": "3876803",
"properties": {
"name":"another name",
"description": "some description",
"website": "afancywebsite"}}]
I started coding this but I have no idea how to get it working...
for(var i in json1.features){
for (var z in json2.features){
if (json1.features[i].id===json2.features[z].id){
json1.feature[i].properties = json2.features[z].properties}}}

This will do the job:
var features = [
{"id": "3876802",
"properties": {
"name": "some name",
"facts": "some facts"}
},
{"id": "3876803",
"properties": {
"name":"another name"
}
}
];
var features2 = [{
"id": "3876803",
"properties": {
"description": "some description",
"website": "afancywebsite"
}
}
];
features.map(function(feature){
var matchedArray = features2.filter(function(feature2){
return feature2.id === feature.id;
});
if(matchedArray && matchedArray[0]){
for(var attr in matchedArray[0].properties){
feature.properties[attr] = matchedArray[0].properties[attr];
}
}
});
We start by using Array.map() to run through the 'features' array, one by one.
Then we use Array.filter() on the features2 array which gives us an array containing the only object in features2 (matched[0]) which has the same id as feature.id.
If there's a match, then we run through the 'properties' in the features2 object using a 'for in' loop and copy them to the 'feature' object.
If you want to get advanced info about this check out this stackoverflow question: How can I merge properties of two JavaScript objects dynamically?. For example, if you're writing bullet-proof javascript you should use 'hasOwnProperty' in a for in loop.
You may also want to guard against properties in 'features2' overwriting a property with the same name in 'features'.
However if you would like to keep your code more or less as it was this also works:
for(var i in features){
for (var z in features2){
if (features[i].id===features2[z].id){
for(var attr in features2[z].properties){
features[i].properties[attr] = features2[z].properties[attr];
}
}
}
}

Iterate through nested Javascript Objects from API response

I've tried 100 different things, and spend days looking through Google and Stackoverflow, but I can't find a solution to this problem. Everything I call after the body of this API response returns undefined!
The response from Facebook SDK looks like this:
[
{
"body": "[
"data": [
{
"name": "Larry Syid Wright",
"administrator": false,
"id": "xxx"
}, {
"name": "Melissa Long Jackson",
"administrator": false,
"id": "xxx"
}, {
"name": "Charlotte Masson",
"administrator": false,
"id": "xxx"
}
],
"paging": {
"next": "url"
}
]"
},{
"body": "{
"data": [
{
"id": "xxx_xxx",
"message": "In honor of Halloween, how many of you have your own ghost stories? Who believes in ghosts and who doesn't?",
"type": "status",
"created_time": "2014-10-31T20:02:01+0000",
"updated_time": "2014-11-01T02:52:51+0000",
"likes": {
"data": [
{
"id": "xxx",
"name": "Joe HerBatman Owenby Jr."
}
],
}
"paging": {
"cursors":
{
"after": "xxx",
"before": "xxx"
}
}
}
},{
"id": "xxx_xxx",
"from": {
"id": "xxx",
"name": "Jessica Starling"
},
"message": "Watching the "Campaign" and I can't help but notice what a fantastic job they did (Will ferrell and all) with that North Carolina accent! Ya'll know we sound different than other southern states ;)",
"type": "status",
"created_time": "2014-11-01T02:36:21+0000",
"updated_time": "2014-11-01T02:36:21+0000",
"likes": {
"data": [
{
"id": "xxx",
"name": "Scott Williams"n
}
]
}
}
],
"paging": {
"previous": "xxx",
"next": "xxx"
}
}"
}
]
This response is from a batch call. If I call them separately, I can easily iterate through the responses, and get everything from them. When I call them in the batch though, I can't get past "body", and I need to use a batch call.
console.log(response[0].body); will return the object inside the body of the first part of the response, but console.log(response[0].body.data); returns undefined. I just don't get it. This should be simple but it's like there's a lock on the door and I don't have the right key.
I normally have no issue iterating through objects, so I don't need a generalized answer. I need help seeing whatever it is here that I don't see. Why does the console show undefined when I call anything after the body, and what do I need to be doing to get any of these values?

That JSON contains nested JSON. body seems to be a string. Use
var body = JSON.parse(response[0].body);

The values from the body are just strings.which are embedded as json.So firstly you would need to parse them using JSON.parse.
The code would be like
var body = JSON.parse(response[0].body);

Angular only pulling last JSON object

Trying to get all JSON objects in an array. It's only returning the last one.
Here's a sample of my JSON:
{
"manufacturer":{
"name": "manufacturername",
"cameras": [
{
"name": "sdfsdfsd",
"type": "Audio device",
"resolution": "Unknown",
"channels": "1"
}
]
},
"manufacturer":{
"name": "manufacturername2",
"cameras": [
{
"name": "sdfsdf",
"type": "Camera",
"resolution": "720P/1.3MP",
"channels": "2"
},
{
"name": "D12",
"type": "Camera",
"resolution": "1080P/3MP",
"channels": "1"
}
]
}}
It is valid JSON.
Here's how I'm calling it:
//Get Manufacturer data
$http.get('data2.json').success(function(data) {
$scope.maninfo = data;
console.log($scope.maninfo);
});
The actual array is much longer - and it's just returning the last Object for some reason.

What you have is valid JSON, but it doesn't correctly express your intent. "manufacturer" (or "name", or "cameras") isn't a type name, it's a unique key into a collection of named values -- dictionary, map, hash, whatever(1). JSON data structures are just a subset of JavaScript object literal declarations (hence the name: JavaScript Object Notation).
So the example above is not an array, it's two successive value assignments to the "manufacturer" property of the same parent object. The parser is assigning the first one to the "manufacturer" property, then replacing that with the second (and in your original, larger) "array", it's then replacing that with the third, and so on.
The "cameras" properties in the manfacturer objects are properly functioning arrays. Just do the same at the higher level -- something more like this:
{
"manufacturers":
[
{
"name": "manufacturername",
"cameras": [
{
"name": "sdfsdfsd",
"type": "Audio device",
"resolution": "Unknown",
"channels": "1"
}
]
},
{
"name": "manufacturername2",
"cameras": [
{
"name": "sdfsdf",
"type": "Camera",
"resolution": "720P/1.3MP",
"channels": "2"
},
{
"name": "D12",
"type": "Camera",
"resolution": "1080P/3MP",
"channels": "1"
}
]
}
]
}
(1) Dictionary, map, hash -- or "associative array". But I didn't want to call it any kind of "array" in that paragraph, because the whole point is it's not the other kind of array.
