Razor Pages Javascript Ajax not passing parameters to c#

I have a Javascript function that is meant to end with passing an array back into my c# code
I have got it to reach the c# code, but it never passes a parameter
My Javascript is as follows
var errorsubmits = [];
var filelists = [];
var nameselect = document.getElementById("username");
var nameselected = nameselect.options[nameselect.selectedIndex].text;
if (nameselected.includes("User"))
errorsubmits.push("User Name");
var prioritylevel = document.getElementById("priority");
var priorityselected = prioritylevel.options[prioritylevel.selectedIndex].text;
if (priorityselected.includes("Priority"))
errorsubmits.push("Priority");
var table = document.getElementById("FileTable");
var counter = 0;
var filename = "";
var images = "";
var envs = "";
var printmethod = "";
var encmethod = "";
var colour = "";
var commentsforprint = "";
var commentsforenclose = "";
for (var i = 1, row; row = table.rows[i]; i++) {
for (var j = 0, col; col = row.cells[j]; j++) {
if (counter == 0) {
if (j == 0)
filename = table.rows[i].cells[j].children[0].value;
if (j == 1)
images = table.rows[i].cells[j].children[0].value;
if (j == 2)
envs = table.rows[i].cells[j].children[0].value;
if (j == 3)
printmethod = table.rows[i].cells[j].children[0].value;
if (j == 4)
encmethod = table.rows[i].cells[j].children[0].value;
if (j == 5)
colour = table.rows[i].cells[j].children[0].value;
}
else {
if (j == 1) {
if (table.rows[i].cells[j - 1].innerHTML.includes("Print"))
commentsforprint = table.rows[i].cells[j].children[0].value;
else
commentsforenclose = table.rows[i].cells[j].children[0].value;
}
}
}
if (i % 3 == 0) {
if (filename == "")
errorsubmits.push("Filename (row:" + i + ")");
if (images == "")
errorsubmits.push("Images (row:" + i + ")");
if (envs == "")
errorsubmits.push("Envs (row:" + i + ")");
if (printmethod.includes("Method"))
errorsubmits.push("Print Method (row:" + i + ")");
if (encmethod.includes("Method"))
errorsubmits.push("Enc Method (row:" + i + ")");
if (colour.includes("?"))
errorsubmits.push("Colour (row:" + i + ")");
// alert(filename + "\n" + images + "\n" + envs + "\n" + printmethod + "\n" + encmethod + "\n" + colour + "\n" + commentsforprint + "\n" + commentsforenclose);
filelists.push(nameselected + "\t" + priorityselected + "\t" + document.getElementById('Email').textContent + "\t" + filename + "\t" + images + "\t" + envs + "\t" + printmethod + "\t" + encmethod + "\t" + colour + "\t" + commentsforprint + "\t" + commentsforenclose)
filename = "";
images = "";
envs = "";
printmethod = "";
encmethod = "";
colour = "";
commentsforprint = "";
commentsforenclose = "";
counter = 0;
}
else {
counter++;
}
}
if (errorsubmits.length != 0) {
alert("Cannot submit!\nThe following lines need filling:\n" + errorsubmits.join("\n"));
}
else {
$.ajax({
url: '?handler=Test',
contentType: 'application/json',
data: JSON.stringify(filelists)
});
}
My C# code which is currently functionless as i cant get the data is this
public JsonResult OnGetTest(IEnumerable<object>x)
{
return new JsonResult("TEST");
}
I have done an alert(JSON.stringify(filelists)) so i know that this works
(If possible i'd like to pass the raw array rather than stringifying it but i was following another SO suggestion)

The url '?handler=Test' send request like https://localhost:44389/?handler=Test&filelists=%5B%22nameselected%22%2C%22nameselected1%22%5D, because it's a HttpGet request not a POST.
Edit as per comment
1 - Function JS :
Push any string in the array filelists, and change your data to { "filelists": JSON.stringify(filelists) }
var filelists = [];
// push strings here
$.ajax({
url: '?handler=Test',
contentType: 'application/json',
data: { "filelists": JSON.stringify(filelists) }
});
2 - In the server side
public JsonResult OnGetTest(string filelists)
{
IEnumerable<string> files = JsonConvert.DeserializeObject<IEnumerable<string>>(filelists);
return new JsonResult("TEST");
}
Note that, if you need to send javascript objects in the array, you should create classes for deserializing data.

How to process large jquery each loop without crashing browser(mainly firefox)

I made a javascript code to create some html element in parent iframe based on user selection from an iframe in a popup.
My code is given below.
The each loop may contain 50 to 150 iteration. Sometimes when I call function AddProcedures the Mozilla crashes during iteration, Is there any way to fix this issue or to reduce the browser load. I tried to put setTimeout after some code blocks but it didn't help.
I have also changed the for loop to jquery each, just to try if that helps.

Multiple Group By using two look-up columns which have multi valued selection enabled on an SP 2013 list using JavaScript

So I'm working on SP 2013 and have a document library which has three Lookup columns viz : Business Unit, Axis Product and Policy form. What I'm trying to do is I have managed to group by the List items first by Business Unit column and then by the Axis Product Column. This works fine but recently I'm trying to show the count of the number of items inside a particular Axis Product. Which would be like - Axis Product : "Some Value" (Count).
I'm able to show this count with Business Unit, but not able to do this with Axis Product. So I tried querying the library with both Business Unit and Axis Product to get the count for Axis Product, I'm not sure about this approach and currently I'm getting an error message:
'collListItemAxisProduct' is undefined.

// JavaScript source code

You have to call clientContext.executeQueryAsync after calling clientContext.load in order to populate any results from the SharePoint object model.
executeQueryAsync takes two parameters: first the function to execute on success, and second the function to execute if an error is encountered. Any code that depends on successfully loading values from the query should be placed in the on success function.

Javascript Hanging UI on IE6/7

Could anyone suggest performance improvements for the function I've written (below, javascript with bits of jquery)? Or point out any glaring, basic flaws? Essentially I have a javascript Google map and a set of list based results too, and the function is fired by a checkbox click, which looks at the selection of checkboxes (each identifying a 'filter') and whittles the array data down accordingly, altering the DOM and updating the Google map markers according to that. There's a 'fake' loader image in there too at the mo that's just on a delay so that it animates before the UI hangs!
function updateFilters(currentCheck) {
if (currentCheck == undefined || (currentCheck != undefined && currentCheck.disabled == false)) {

However, I'm suffering from performance issues (UI hanging) specifically in IE6 and 7 when the number of results is high, but not in any other modern browsers, i.e. FF, Chrome, Safari etc. It is much worse when the Google map markers are being created and added (if I remove this portion it is still slugglish, but not to the same degree). Can you suggest where I'm going wrong with this?
Thanks in advance :) Please be gentle if you can, I don't do much javascript work and I'm pretty new to it and jquery!

This looks like a lot of work to do at the client no matter what.
Why don't you do this at the server instead, constructing all the HTML there, and just refresh the relevant sections with the results of an ajax query?
