How Split and Find Text Value in Array

How can I spilt below Array and print verificationCode= "value" in consle.log
var backup = [{kind=admin#directory#verificationCode, etag="HIWxtAjmBmqPQjjDV2Duo181uSc/ojhx3q8-0EqFY6M1x0NOJ85j1xg", userId=116800256069112846055, verificationCode=37140335}]

You need to correct your JS object to be in this format here.
var backup = [
{kind:"admin#directory#verificationCode",
etag:"HIWxtAjmBmqPQjjDV2Duo181uSc/ojhx3q8-0EqFY6M1x0NOJ85j1xg",
userId:"116800256069112846055",
verificationCode:"37140335"}
]
and then you can use the following to access your values
backup[0].verificationCode;

JSON to JS array

JSON:
[{"CDATE":"0000-00-00","DISTANCE":"0"},
{"CDATE":"0000-00-00","DISTANCE":"1"},
{"CDATE":"0000-00-00","DISTANCE":"2"},
{"CDATE":"0000-00-00","DISTANCE":"3"}]
Is it possible to put all the distance value in their own array in JS? The formatting will be consistent as it comes from an API and is always formatted correctly.
What I've tried:
var arry = [ /* JSON noted above */ ];
alert(arry[1])
and
var arry = JSON.parse([ /* JSON noted above */ ]);
alert(arry[1])
Expected:
1
Actual:
{"CDATE":"0000-00-00","DISTANCE":"1"}
and the other gives an error.
I would like to extract just the DISTANCE value as an array of DISTANCE
I've tried JSON.parse() but I don't think this is what I am after as it hasn't worked for me.

Use .map
var data = [{"CDATE":"0000-00-00","DISTANCE":"0"},
{"CDATE":"0000-00-00","DISTANCE":"1"},
{"CDATE":"0000-00-00","DISTANCE":"2"},
{"CDATE":"0000-00-00","DISTANCE":"3"}];
var distance = data.map(el => el.DISTANCE);
console.log(distance[2]);
console.log(distance);
It is already a valid json so you do not need to use JSON.parse()

Parsing JSON and loading into array

JSON-https://www.alphavantage.co/query?function=TIME_SERIES_DAILY&symbol=MSFT&apikey=demo
I am trying to take the JSON from the above link and place it in the following format(date,open,high,low,close)...
[
[1277424000000,38.58,38.61,37.97,38.10],
[1277683200000,38.13,38.54,37.79,38.33],
[1277769600000,37.73,37.77,36.33,36.60],
[1277856000000,36.67,36.85,35.72,35.93],
]
The date does not need to be Epoch time.
My code....
$.getJSON('https://www.alphavantage.co/query?
function=TIME_SERIES_DAILY&symbol=MSFT&apikey=demo', function(data) {
//Get the time series data
var timeseries = data['Time Series (Daily)']
var ohlcarray = [];
//Loop through each time series and convert it to JSON format
$.each(timeseries, function(key, value) {
var ohlcdata=[];
ohlcdata[0]=value[0];//date
ohlcdata[1]=value[1];//open
ohlcdata[2]=value[2];//high
ohlcdata[3]=value[3];//low
ohlcdata[4]=value[4];//low
ohlcarray.push(ohlcdata);
});
console.log(ohlcarray[0]);//test if worked properly
});
The output....
[undefined, undefined, undefined, undefined, undefined]
value[x] returns undefined. Any ideas on why this happens?
Thanks!

The reason is that in the each loop, the value is not a list but an object. To access it, you'd have to grab it using keys.
ohlcdata[0] = key; //date
ohlcdata[1] = value['1. open']; //open
ohlcdata[2] = value['2. high']; //high
ohlcdata[3] = value['3. low']; //low
ohlcdata[4] = value['4. close']; //low

At this point it is already JSON. As Patrick mentioned, getJSON automatically parses json. You will need to access it with the array bracket notation since there are spaces in the property name.
var timeSeries = data['Time Series (Daily)'];

set array as value in json format in Javascript

I want to add array as json value.
Json format is as follows.
json_data = [
'name':'Testing'
'email':'TestEmail'
'links':[
'test#test.com',
'test#test1.com',
'test#test3.com']
]
How can I set value of 'links' in javascript like that?
I did as follows.
links_array = [];
links_array =['testing','test2'];
json_data.links = links_array;
I wanted to append these two string but couldn't.
Any help would be appreciate.

Assuming that the syntax of your example is correct, you can use the "push" method for arrays.
json_data = {
'name':'Testing',
'email':'TestEmail',
'links':[]
};
json_data.links.push("test1#test.com");
json_data.links.push("test2#test.com");
json_data.links.push("test3#test.com");

You have to make little changes to make it work.
First thing, You have to replace initial square brackets with curly one. By doing this your object will become JSON Literal - a key value pair.
Second thing, You have missed commas after 'name':'Testing' and 'email':'TestEmail'
Below will work perfectly:
var json_data = {
'name':'Testing',
'email':'TestEmail',
'links':[
'test#test.com',
'test#test1.com',
'test#test3.com']
}

In addition to push as mentioned by #giovannilobitos you can use concat and do it all in one go.
var json_data = {
'name':'Testing',
'email':'TestEmail',
'links':[
'test#test.com',
'test#test1.com',
'test#test3.com'
]
};
var links_array = ['testing','test2'];
json_data.links = json_data.links.concat(links_array);
console.log(json_data.links);

fetch data from nested JSON object in a single line

This is my JSON data ....
{"comp1":["$.Create_Keypair1_Keypair_name"]}
I want to get the value "Create_Keypair1_Keypair_name".but all the keys and values are dynamic.but the object always have single data.
I have Object.keys(temp).It shows only ["comp1"] i need
$.Create_Keypair1_Keypair_name only....

Try this:
var data = {"comp1":["$.Create_Keypair1_Keypair_name"]}
for (var key in data) {
console.log(data[key])
}
This will log $.Create_Keypair1_Keypair_name.

From what I am understanding each object will have a single value. If the is the case then you do not need the array in the object. You can do this.
var tempy = {"comp":"ksmdfnsfdnsdfn"}
Then do this to ge the value.
tempy.comp
Or if you need the keys.
Object.keys(tempy)

you might be looking for this
var temp = {"comp1":["$.Create_Keypair1_Keypair_name"]}
Object.keys(temp).forEach(function(key){
console.log(temp[key]);
});
