How to get string converted to array?

I am kind of new to this, but this is giving me a headache.
Heres my code what i am trying to solve:
function parseComponents(data: any, excelAttributesArray: string[]) {
let confs = "";
let isValues = false;
let listValues = "";
if (!data) return confs;
if (data["Part"]) {
const part = data["Part"];
excelAttributesArray.forEach((attribute) => {
let attributeValue = part[attribute];
if (attributeValue !== null) isValues = true;
if (attributeValue !== null && attributeValue.Value) {
attributeValue = attributeValue.Value;
}
listValues += attributeValue + ",";
});
const number = part["Number"];
if (isValues) {
confs += `${listValues}${number}`;
}
}
if (data["Components"] && data["Components"].length > 0) {
for (let i = 0; i < data["Components"].length; i++) {
const tmp = parseComponents(
data["Components"][i],
excelAttributesArray
);
if (tmp && tmp.length > 0)
confs += (confs.length > 0 ? "|" : "") + tmp;
}
}
return confs;
}
The confs value is returned as a string. How do i get it return as array?

Encode letter to number

I feel like I am failing everything this semester. but I was wondering if you all could help me with a JS project. We have been tasked with essentially converting numbers to letters and vica versa using textareas in HTML. I was able to do the numbers to letters function, but am having difficulties going the other way. what I have for all is:
var $ = function(id) {
return document.getElementById(id);
};
window.onload = function() {
$("btnDecode").onclick = fnDecode;
$("btnEncode").onclick = fnEncode;
$("btnClear").onclick = fnClear;
};
function fnDecode() {
var msg = $("textin").value;
if (msg === "") {
$("textin_span").innerHTML = "* Please enter a message to decode *";
$("textin").focus;
return;
} else {
$("textin_span").innerHTML = "";
}
var nums = msg.split(",");
var outstr = "";
for(var i=0; i < nums.length; i++) {
var n2 = parseInt(nums[i]);
if (isNaN(n2)) {
outstr += "?";
} else if (isNallN(nums[i])) {
} else if (n2 === 0) {
outstr += " ";
} else if (n2 < 1 || n2 > 26) {
outstr += "?";
} else {
outstr += String.fromCharCode(n2+64);
}
$("textout").value = outstr;
}
}
function isNallN(s) {
//parse string to check all characters are digits
}
function fnEncode() {
var msg = $("textin").value.toUpperCase();
$("textin").value = msg;
if (msg === "") {
$("textin_span").innerHTML = "* Please enter numberse to decode *";
$("textin").focus;
return;
} else {
$("textin_span").innerHTML = "";
}
var c;
var outstr = "";
for (var i=0; i<msg.length; i++);
c = msg.charCodeAt(i);
if (typeof c === "number") {
outstr += "99";
}else if (c === " ") {
outstr += 0;
/*} else if (c[i] >= "A" && c[i] <= "Z") {
outstr += "99";*/
} else {
outstr += String.charCodeAt(c - 64);
}
$("textout").value = outstr;
//var x = msg.charAT(i);
}
obviously isNallN is not complete, but he promised us if we could figure out fnEncode we should be able to do isNallN with no issues (which I am hoping is true lol) What am doing wrong though in fnEncode? Every time I run it, it gives me "99" even when I put letters in.

JavaScript - Make a variable change every second

Ok, so this is my code:
name: function(gameServer, split) {
// Validation checks
var id = parseInt(split[1]);
if (isNaN(id)) {
console.log("[Console] Please specify a valid player ID!");
return;
}
var name = split.slice(2, split.length).join(' ');
if (typeof name == 'undefined') {
console.log("[Console] Please type a valid name");
return;
}
var premium = "";
if (name.substr(0, 1) == "<") {
// Premium Skin
var n = name.indexOf(">");
if (n != -1) {
premium = '%' + name.substr(1, n - 1);
for (var i in gameServer.skinshortcut) {
if (!gameServer.skinshortcut[i] || !gameServer.skin[i]) {
continue;
}
if (name.substr(1, n - 1) == gameServer.skinshortcut[i]) {
premium = gameServer.skin[i];
break;
}
}
name = name.substr(n + 1);
}
} else if (name.substr(0, 1) == "[") {
// Premium Skin
var n = name.indexOf("]");
if (n != -1) {
premium = ':http://' + name.substr(1, n - 1);
name = name.substr(n + 1);
}
}
and i want to change premium to something like <kraken> and <spy> every second, so that then it changes gameServer.skinshortcut to %kraken and then 1 second later it changes that to %spy... and cycles, How do I do this?

Use setInterval(function, delay in ms)

Try:
Var pre_stat=0;
function tgl_pre()
if (pre_stat=0)
{
pre_stat=1;
//change variable to `kraken`;
}
else
{
pre_stat=0;
//change variable to 'spy';
}
setInterval("tgl_pre()", 1000);
end

Check and alert for the null value

I need to check for the null values and alert them if there are any before getting saved. I have used this code but I am not able to alert the null values instead it is getting saved . .
function fn_publish() {
var SessionNames = getParameterByName('SessionName');
var MenuType = getParameterByName('MenuType');
var Date = getParameterByName('ForDate');
var publish = "Y";
Dates = Date.split("-");
Date = Dates[1] + "/" + Dates[2] + "/" + Dates[0];
var rows = [];
cols = document.getElementById('product_table').rows[1].cells.length - 1;
table = document.getElementById('product_table');
for (var i = 1; i <= cols; i++) {
for (var j = 0, row; row = table.rows[j]; j++) {
if (j == 0) {
cust = row.cells[i].innerText;
alert(cust);
} else if (j == 1) {
catlg = row.cells[i].innerText;
alert(catlg);
} else {
if (typeof (row.cells[i]) != "undefined") {
if (row.cells[i].innerText != "") {
//alert(SessionNames+"::"+MenuType+"::"+Date+"::"+catlg+"::"+row.cells[0].innerText+"::"+row.cells[i].innerText+"::"+cust+"::"+publish);
fn_insert(SessionNames, MenuType, Date, catlg, row.cells[0].innerText, row.cells[i].innerText, cust, publish);
} else {
jAlert("Please select a product", "ok");
return false;
}
}
}
}
}
jAlert("Menu Published", "ok");
}

if (row.cells[i].innerText != "") {
May be the cells are containing empty space in that. Better trim ad then compare.
if (row.cells[i].innerText.trim() !== "") {
Also instead of innerText use textContent which is common in most modern browsers.
if (row.cells[i].textContent.trim() !== "") {

Javascript(Function to compare objects)

I am trying to create a function which will compare one music album to another but my code does not run. I'd like to know why, because I really cannot see where the problem is and why there is a problem. Thanks very much.

If you run a debugger on your code, you will see that the problem is in the compare function. In particular, argument names cannot contain square brackets.
I would recommend changing your compare function thus:
function compare (album1, album2) {
for (var i in album1) {
if (album1[i] !== album2[i]) return false;
}
return true;
}

Based on your update
Ok there are still plenty of issues with this code.
First and most important, album1 and album2 are not defined before being compared, for 2 reasons.
Main() is not executed until after they run, so album[] has not been defined
album[1] is not the same as album 1
Some more things to think about:
Array indices start at 0 in javascript. Skipping the first index to get your arrays to start at 1 is considered bad practice.
Instead of the 24 prompts you're doing right now, you should probably consider forms for input. 24 prompts in a row will be very annoying for a user.
You probably want a modal window for your HQ verification. Something like this
An attempt at cleaning up the code
I think you should probably rethink some of the choices here, but here's a cleaned up version of the code that at the very least runs:
jsfiddle
<script type="text/javascript">
/********* FUNCTIONS *********/
function compare(album1, album2)
{
for (var i in album1)
{
if (album1[i] !== album2[i]) return false;
}
return true;
}
/********* MAIN *********/
function main()
{
var album = [];
var numAlbums = 2;
for (var i = 0; i < numAlbums; i++) {
album[i] = {};
album[i].artistName = prompt("What is the artist's name?");
album[i].albumTitle = prompt("What is the album title?");
album[i].releaseYear = parseFloat(prompt("What is the album's release year"));
var hq = prompt("Is the album high quality? Y/N")
if(!hq)
{
hq = "";
}
while (true)
{
hq = hq.toUpperCase();
if( hq==="Y" || hq === "YES" )
{
album[i].ifHQ = true;
break;
}
else if( hq ==="N" || hq === "NO" )
{
album[i].ifHQ = false;
break;
}
else
{
hq = prompt(
"You have entered an invalid response. Is " +
album[i].title + " a ifHQ album, Y/N?");
}
}
album[i].tracks = [];
for (var j = 0; j < 10; j++)
{
album[i].tracks[j] = prompt("Enter track" + (j + 1));
}
}
var same = compare(album[0], album[1]);
document.write(same);
}
// This line calls main, don't change it:
