How do I parse part of a JSON object that has mixed string and numbers?

I have a JSON file that was processor generated with lines like this
jsonData: "{data: [350.23,250.32,150.34,340.50,236.70,370.45,380.55]}"
I can target the 'jsonData' object but that returns everything within the double quotes as a string.
I tried ...dataset[0].jsonData[8] which returns the '3' from the first value. I guess I could throw the mixed strings into a JS function and use regex to remove the extra stuff, but thats probably the hackyest way to do this.
Whats the easiest way to target the values only?

If you want to interact with it like the list I would consider something like
var list = jsonData.split("[")[1].split("]")[0].split(",")
Console.log(list);
The console reads:
[
'350.23', '250.32',
'150.34', '340.50',
'236.70', '370.45',
'380.55'
]
From here you can use list[3] to get 340.50

If you don't want to spend the time fixing your JSON just do this:
let values = "{data: [350.23,250.32,150.34,340.50,236.70,370.45,380.55]}".split(',').map(_ => _.replace(/[^0-9.]/g,''))
console.log(values)

loop in JSON with undefined elements

I am trying to figure out how to retrieve the values of a json of which i do not know the number of elements.
Example:
my json can be something like
var json = ["fixelement1":"value1","fixelement2":"value2","fixelement3":"value3","variableelement4":"value4","variableelement5":"value5"]
or
var json =["fixelement1":"value1","fixelement2":"value2","fixelement3":"value3","variableelement7":"value7","variableelement8":"value8", "variableelementN":"valueN"]
the only thing that I know is that the first 3 elements are always the same.
I use .indexOf() to search a value in fixelement3. What I would like to do is, if I find the element, I would like to retrieve the name of all the following elements (which number is variable and that are unknown) and their values.
javascript or jquery would work for me, but I have no idea..
thank you in advance!

var json ={
"fixelement1":"value1",
"fixelement2":"value2",
"fixelement3":"value3",
"variableelement7":"value7",
"variableelement8":"value8",
"variableelementN":"valueN"
}
for(prop in json){
console.log('key ======> value', prop, '=====>', json[prop]);
}

Converting json array to query string gives null

What I am trying to achieve is to send a json object as a querystring to an API.
The json object I have is:
{
"Name":"Dlsajdsa",
"ImageUrls":["/Images/Facility/8353/85e26a18-4366-4412-b37a-72d94f2ccda5.jpg"]
}
I would like to convert this to something like ?Name=&ImageUrls=
However, when using $.param(json) I get the following:
?Name=Dlsajdsa&ImageUrls%5B%5D=%2FImages%2FFacility%2F8353%2F85e26a18-4366-4412-b37a-72d94f2ccda5.jpg
This result, on the API point of view, that the ImageUrls array is null.
What am I missing here?

you can try $.param(json,true)

Based on the documentation of jQuery.param, I'd say this is the piece of code you want to use:
var json = {
"Name":"Dlsajdsa",
"ImageUrls":["/Images/Facility/8353/85e26a18-4366-4412-b37a-72d94f2ccda5.jpg"]
};
var recursiveDecoded = decodeURIComponent($.param(json));
// "Name=Dlsajdsa&ImageUrls[]=/Images/Facility/8353/85e26a18-4366-4412-b37a-72d94f2ccda5.jpg"

The query parameter is called ImageUrls%5B%5D, that means ImageUrls[], not ImageUrls as you expect.

Change a json/javascript object var name or retrieve values from a numerical var

I've some page that gives me kinda of a JSON file/output like this
example:
Description:
23463232
tags
appid
35433523
tags
appid
12345234
tags
appid
I'm trying to get the tags values, like so description.23463232.tags
Add gives me this error:
SyntaxError: identifier starts immediately after numeric literal
I know that you all vars must be strings started by letters but I can't change that because this file/page is not mine. So, I'd like to know what can I do to retrieve the tags values or if there is some way to change the name of that vars like "23463232" to something else.

That number is probably a string. You can try using the square bracket syntax for reading JSON like so: description["23463232"]["tags"]

You can use property accessor to access any property name:
description["23463232"].tags
Just for completeness of the answer, if you still need to change the variables, you can do this:
for(var key in description) {
var value = description[key];
//copy the value to a new key (_ prepended) then delete the original key.
description["_"+key] = value;
delete description[key];
}
Now you can access the values like: description._23463232.tags

Cant extract variable data into a string format for passing to a db

Currently I have all the following held within a variable.(badgeselected). Which returns the following in console.log
[<img id=​"go" src=​"http:​/​/​kudosoo.com/​Pics/​Lisa_Wong.jpg" alt=​"img" style=​"cursor:​ pointer;​">​ , <div id=​"go">​</div>​ ]
Using js/juery I'd like to extract just the url so I can store it in a db as a string
How can I do this? At the moment I have the variable defined as the following, but I'm not sure if .val is correct to turn it into a string?
var badgeselected = $("#badge").val();

Just do this
$("#badge").attr("src")
