Iterate over JSON data in JavaScript

I am working on some trains' open data feed and getting some JSON as a response from a server. I parse this JSON into a data variable and display it as seen below. However, I cannot find a way to iterate over the response to be able to manipulate each message. I want to iterate over each message and then use the data for a record in a SQL database. I cannot get to the point of accessing any individual message data.
How can I create a loop to iterate over each message and extract it's data?
[
{
SF_MSG: {
time: '1666370311000',
area_id: 'TD',
address: '0C',
msg_type: 'SF',
data: '1F'
}
},
{
CA_MSG: {
to: '4333',
time: '1666370311000',
area_id: 'WO',
msg_type: 'CA',
from: '4331',
descr: '2K60'
}
}, ...
]
Edit: using data.forEach(function(message) produces an output of the structure:
{ CA_MSG: { to: '6021', time: '1666372120000', area_id: 'CY', msg_type: 'CA', from: 'STIN', descr: '2Y73' } }
, however, how do I query this inner object, the names of the objects will differ depending on message type if this matters?

try this:
data = JSON.parse(yourJSONdata)
data.map((o, i)=>{
//o is the object, i is the index
// do your processing here
then at the end do
data[i]=processedobject
})

Printing Object doesnt contain all keys

Im completely lost. This is some test code I use to print a specific key of an object, then im printing the entire object.
console.log(docs[0].mc_ign);
console.log(docs[0]);
Now this is the output I see on the console:
The__TxT
{
id: 0,
status: 1,
testing: false,
_id: 5dbc17eb20b3a8594d569570,
timestamp: 2019-11-01T11:32:59.380Z,
mc_uuid: 'dac89e44d1024f3b810478ed62d209a1',
discord_id: '653029505457586176',
email_address: 'gut97930#eveav.com',
country: 'Germany',
birth_month: 3,
birth_year: 1943,
about_me: 'about me text',
motivation: 'motivation text',
build_images: '',
publish_about_me: true,
publish_age: false,
publish_country: true,
__v: 0
}
Where is the mc_ign key?
The object itself comes from mongoose, the missing key is added by me after the fact:
docs[i].mc_ign = mc_ign;
I tried logging the entire object before and after I add the key and assign the value. They are both the same.
What am I missing? Why can I read the value out, but cant see it?

It is mongoose document object. To achieve what you want do the following.
docs[0] = docs[0].toObject();
docs[0].mc_ign = "stuff";
console.log(docs[0])
.toObject() convert it to plain JS object.

How to convert object in array js [duplicate]

This question already has answers here:
Parse JSON in JavaScript? [duplicate]
(16 answers)
Closed 4 years ago.
I very new to programming and I can't find the solution of my issue, can you give me the solution please?
I have this JSON file:
{
"groups": "[{ id: 1, title: 'group 1' }, { id: 2, title: 'group 2' }]"
}
And I need something like this in my js (but i want import my JSON to get array like this) :
const groups = [{ id: 1, title: 'group 1' }, { id: 2, title: 'group 2' }]
I don't know how to do without using jQuery.
I already tried with this:
const json = require('./test.json');
This code returns an object:
It's almost what I want but it didn't work when I use it in my code because I don't want an object but and array like I said above.
How can achieve this?

The value of groups is not valid JSON: string values should be surrounded by double-quote marks, and so should keys. The file with valid JSON in that string would look like this:
{
"groups": "[{ \"id\": 1, \"title\": \"group 1\" }, { \"id\": 2, \"title\": \"group 2\" }]"
}
Of course if you have control over the creation of this file, it would be better to have this value as part of the native JSON content, rather than JSON-in-a-string-inside-JSON. If that's not possible, you will need to correct the quoting in the string yourself, which can be done with a couple of Regular Expression replacements.
/* obj is the object in the JSON file */
var json_str = obj.groups.replace(/'/g,"\"").replace(/([a-z]+)\:/g,"\"$1\":");
var groups = JSON.parse(json_str);
Alternatively, although the string is not valid JSON it is a valid Javascript expression, so if the contents of the file are trustworthy, you can also do it with eval:
var groups = eval(obj.groups);

I just need to fill my array "groups" like that :
[{ id: 1, title: 'group 1' }, { id: 2, title: 'group 2' }]
with a json file and without jquery

Since I didn't notice the "without jQuery" in the original question, here is a new answer:
var request = new XMLHttpRequest();
request.open('GET', './test.json', true);
request.onload = function() {
if (request.status >= 200 && request.status < 400) {
// Success!
var data = JSON.parse(request.responseText);
} else {
// We reached our target server, but it returned an error
}
};
It does two things:
1. Loads the json file
2. Parses the loaded string into a javascript object.

Before you can even do anything with your JSON file, you need to load it. jQuery has a shortcut, which will even automatically parse the JSON-string into a native JS object for you:
$.getJSON('./test.json', function(data) {
console.dir(data);
});
https://api.jquery.com/jquery.getjson/

if you can't edit original text, you need replace ' to " and then did JSON.parse(json.groups);
otherwise you can change a little your json like this:
JSON.parse('[{ "id": 1, "title": "group 1" }, { "id": 2, "title": "group 2" }]')
be careful with " and ' parentheses
{
"key":"string"
}
string with defined with ' parentheses not valid
in JSON keys must be to in "" parentheses

You can parse the object to an array this way:
Object.values(YOUR_OBJECT)

formatting bound property in javascript before it is displayed

I'm trying to format a JSON date to a JavaScript date to display it in a nice way. The original date comes from a JSON-object, which looks like this:
{
"name": "foo",
"num": "1",
"date": "\/Date(1367539200000)\/"
}
The place where the JSON elements should be displayed later is a SAPUI5 object header:
objectHeader = new sap.m.ObjectHeader({
title: "{/name}",
number: "{/num}",
attributes: [
new sap.m.ObjectAttribute({
text: "{/date}"
})
]
});
Since the JSON object is bound to the object header via
dataModel.setData(json)
objectHeader.setModel(dataModel)
the values are correctly substituted. But i want to have the date correctly formatted to a more readable format instead of seeing /Date(1367539200000)/ on my website. I tried with
new sap.m.ObjectAttribute({
text: new Date(parseInt("{/date}".substr(6))).toLocaleString('de');
})
But that failed with an 'Invalid Date'. What would be the right syntax to format the JSON date to a Javascript data object in a model binding?

You can use a formatter to do that for you. The advantage is that you can properly use databinding, so your controls will be updated automatically in case the model changes.
new sap.m.ObjectAttribute({
text: {
parts: [
{path: "/date"}
],
formatter: function(date){
//do whatever you want
return /* the value you want to have as result */;
}
}
})

Schedule multiple local notifications

Im using the local notifications plug-in https://github.com/katzer/cordova-plugin-local-notifications, and i'm trying to schedule multiple notifications but I only get the first one.
It has something to do with the id, but I don't know if it suppose to be a object or a value I've been tracing this everywhere and are really grateful for all help!
var now = new Date().getTime(),
_60_seconds_from_now = new Date(now + 30*1000);
_120_seconds_from_now = new Date(_60_seconds_from_now.getTime() + 60*1000),
window.plugin.notification.local.add({
id: 28,
title: 'Reminder',
message: 'Dont forget to buy some ds.',
repeat: 'minutely',
date: _60_seconds_from_now
});
window.plugin.notification.local.add({
id: 27,
title: 'Reminder',
message: 'Dont forget to buy some dsfsdafsdafsdaf.',
repeat: 'minutely',
date: _120_seconds_from_now
});

I think by making repeat minutely first one is overlapping the second one... make sense ??
