Problem with dynamic size array in javascript

I am trying to develop my own game engine running on JavaScript for text adventure games. It's more of a personal project than actually trying to go anywhere with it, but none the less, I am having fun.
The problem I am currently getting is Uncaught TypeError: optionGroups[(num + 1)] is undefined from my console, as well as a reference to line 97 in filereader.js. I believe that this is because of how I am defining the array, or trying to use it, but I am also unsure of the "correct" way to do so.
My filereader.js file
var raw;
function initFileReader(){
document.getElementById('fileInput').addEventListener('change', handleFileSelect, false);
}
function handleFileSelect(event){
const reader = new FileReader()
reader.onload = handleFileLoad;
reader.readAsText(event.target.files[0])
}
function handleFileLoad(event){
//console.log(event.target.result);
raw = event.target.result;
//All save files should be marked with MSF somewhere in the file.
if (!raw.includes("MSF")){
alert("Not a Save File");
}
else{
/*

Why isn't my JavaScriptcode working with prompt and innerHTML?

Im trying to make an online Role Playing Game, but my code is not working. It asks the user what they want their character to be named, and what race they want to be. It would then randomly choose some stats for them, and -- depending upon their race -- add and subtract from their stats.
var nameAndRaceFunction = function(){
var namePrompt = prompt("What shall you name your character?");
var racePrompt = prompt("What race shall your character be? Please spell it correctly, with no capitals.");
var race = racePrompt.toLowerCase();
var totalSentence = namePrompt + " the " + race;
document.getElementById("nameAndRace").innerHTML = totalSentence;
}
var str = Math.floor((Math.random() * 10) + 1);
var int = Math.floor((Math.random() * 10) + 1);
var hlth = Math.floor((Math.random() * 10) + 1);
var dext = Math.floor((Math.random() * 10) + 1);
var getStatFunction = function(){
if(racePrompt === "elf"){
elfStats();
}else if(racePrompt === "dwarf"){
dwarfStats();
}else if(racePrompt === "man"){
manStats();
}else{
}
}
var elfStats = function(){
var elfStr = str;
var elfInt = int + 1;
var elfHlth = (hlth - 1)*10;
var elfDext = dext + 1;
document.getElementById("strength").innerHTML = elfStr;
document.getElementById("intelligence").innerHTML = elfInt;
document.getElementById("health").innerHTML = elfHlth;
document.getElementById("dexterity").innerHTML = elfDext;
}
var manStats = function(){
var manStr = str + 2;
var manInt = int;
var manHlth = (hlth - 1) * 10;
var manDext = dext;
document.getElementById("strength").innerHTML = manStr;
document.getElementById("intelligence").innerHTML = manInt;
document.getElementById("health").innerHTML = manHlth;
document.getElementById("dexterity").innerHTML = manDext;
}
var dwarfStats = function(){
var dwarfStr = str + 1;
var dwarfInt = int;
var dwarfHlth = (hlth + 1) * 10;
var dwarfDext = dext - 1;
document.getElementById("strength").innerHTML = dwarfStr;
document.getElementById("intelligence").innerHTML = dwarfInt;
document.getElementById("health").innerHTML = dwarfHlth;
document.getElementById("dexterity").innerHTML = dwarfDext;
}

racePrompt is defined inside the nameAndRaceFunction() function scope. It is not accessible outside of it. Further: you lower case it, so later I will check only for race not racePrompt.
One solution would be to make race global like str, int, hlth, dext
var nameAndRaceFunction = function() {
namePrompt = prompt("What shall you name your character?");
var racePrompt = prompt("What race shall your character be? Please spell it correctly, with no capitals.");
race = racePrompt.toLowerCase();
var totalSentence = namePrompt + " the " + race;
document.getElementById("nameAndRace").innerHTML = totalSentence;
getStatFunction()
}
var namePrompt, race;
var str = Math.floor((Math.random() * 10) + 1);
var int = Math.floor((Math.random() * 10) + 1);
var hlth = Math.floor((Math.random() * 10) + 1);
var dext = Math.floor((Math.random() * 10) + 1);
var getStatFunction = function() {
if (race === "elf") {
elfStats();
} else if (race === "dwarf") {
dwarfStats();
} else if (race === "man") {
manStats();
} else {
}
}

getStatFunction should be called with the race as argument or you should define the variable racePrompt outsite the function
Also, if you mean to make a player, a good idea should be have it as an object and use the nameAndRaceFunction like a constructor

Getting an NaN error - Javascript

Im getting an NaN error in the total grade. Can someone help me to find the cause of this error? Or give me some ideas how to fix this? Im just new to javascript and web development. Sorry for the logic of my code..
here's my code.
function Calculate(){
var term = $("#term").val();
var fac_code = $("#faculty_code").val();
$.ajax({
type: 'POST',
url: 'getrecords.php',
data: {
"done": 1,
"term": term,
"fac_code": fac_code
},
dataType: 'json',
success: function(data)
{
var major = data[3];
var quizzes = data[4];
var homework = data[5];
var attendance = data[6];
var laboratory = data[7];
var activity = data[8];
var recitation = data[9];
var q = +(document.getElementById('quiz').textContent);
var a = +(document.getElementById('atten').textContent);
var h = +(document.getElementById('home').textContent);
var r = +(document.getElementById('reci').textContent);
var m = +(document.getElementById('me').textContent);
var ac = +(document.getElementById('activityy').textContent);
var l = +(document.getElementById('laboratory').textContent);
var ma = $('.me');
var qui = $('.quize');
var homesea = $('.hos');
var re = $('.recits');
var laborat = $('.labo');
var activit = $('.activity');
var attenda = $('.atte');
var MisVisible = ma.is(':visible');
var QisVisible = qui.is(':visible');
var HisVisible = homesea.is(':visible');
var RisVisible = re.is(':visible');
var LisVisible = laborat.is(':visible');
var AisVisible = activit.is(':visible');
var ATisVisible = attenda.is(':visible');
var mt;
var qt;
var ht;
var rt;
var act;
var lt;
var att;
if (MisVisible === true) {
mt = m / 100 * 50 + 50;
}
if (QisVisible === true){
qt = q / 100 * 50 + 50;
}
if(HisVisible === true){
ht = h / 100 * 50 + 50;
}
if(RisVisible === true){
rt = r / 100 * 50 + 50;
}
if(LisVisible === true){
lt = l / 100 * 50 + 50;
}
if(AisVisible === true){
act = ac / 100 * 50 + 50;
}
if(ATisVisible === true){
att = a / 100 * 50 + 50;
}
mtt = mt * (major * 0.01);
qtt = qt * (quizzes * 0.01);
attt = att * (attendance * 0.01);
htt = ht * (homework * 0.01);
rtt = rt * (recitation * 0.01);
actt = act * (activity * 0.01);
ltt = lt * (laboratory * 0.01);
var grade = mtt + qtt + attt + htt + rtt + actt + ltt;
document.getElementById('td_grade').innerHTML = grade;
}
});
}

The best answer would be to know how to use the Dev Tools source pane. Put breakpoints in your code, and start stepping through the code to see the values.
If I were to take a wild guess, one of these is undefined or missing.
var major = data[3];
var quizzes = data[4];
var homework = data[5];
var attendance = data[6];
var laboratory = data[7];
var activity = data[8];
var recitation = data[9];
Or one of these can't be parsed correctly by the unary + as a number
var q = +(document.getElementById('quiz').textContent);
var a = +(document.getElementById('atten').textContent);
var h = +(document.getElementById('home').textContent);
var r = +(document.getElementById('reci').textContent);
var m = +(document.getElementById('me').textContent);
var ac = +(document.getElementById('activityy').textContent);
var l = +(document.getElementById('laboratory').textContent);

Use Chrome's Dev tool by pressing F12 and go to console tab, to check for any variable you can use:
console.log(variable_name);
Additionally, your HTML value maybe not in a form of int so you should not use unary plus to get the value, use this instead to check whether your value is good:
if (!isNaN(parseFloat("10000")){
//do something
}

Javascript function called inside onclick do not instantiate mongoose Model

I have a function called save with this code, it's meant to save data from a timer.
The class with the Model is this:
var Schema = mongoose.Schema;
var Timer = new Schema({
Time: {type: Number},
Desc: {type: String},
Doc: {type: String}
});
Timer.statics.findByDesc = function(value, callback){
this.find({ Desc: {"$regex": value, "$options": "i"}}, callback);
}
Timer.statics.findByDoc = function(value, callback) {
this.find({ Doc: { "$regex": value, "$options": "i" }}, callback);
}
Timer.statics.findAll = function(callback){
this.find({}, callback);
}
module.exports = mongoose.model('Timer', Timer);
the model is defined by this code which is imported with:
var Timer = require('./../../models/timer');
but I'm testing it with constants in a function which is called by clicking button, this is the code inside the function:
var newTimer = new Timer({
Time: 6000, Desc: "My first timertest!", Doc: "Test's Dossier"
});
newTimer.save();
however with trial and error I have figured out that it never calls newTimer.save(), it seems to get stuck somewhere without ever leaving the var newTimer = new Timer() function.
I have tried my Timer Model code in other files with code like:
/**
* Created by kevin on 08/03/2016.
*/
var Timer = require('../models/timer'),
mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/legalapp');
mongoose.connection.on('open', function() {
console.log('Mongoose connected.');
});
var newTimer = new Timer({
Time: 5000, Desc: "My first timertest!", Doc: "Test's Dossier"
});
console.log(newTimer.Time);
console.log(newTimer.Desc);
console.log(newTimer.Doc);
newTimer.save();
mongoose.connection.close();
and this did work, so after 3 hours of trying, I'm going crazy, so I came here.
I am using javascript, nodeJS, jquery and mongoose in my project.
Here is the entire file:
var timers = [], Timer = require('./../../models/timer');
function timer(id){
this.id = id;
this.running = false;
this.start = new Date();
this.current = new Date();

this.m = Math.floor(this.timed / 1000 / 60);
this.timed -= this.m * 1000 * 60;
this.m = checkTime(this.m);
this.s = Math.floor(this.timed / 1000);
this.timed -= this.s * 1000;
this.s = checkTime(this.s);
}
function startTime(timer){
if(!timer.running) {

timer.start = new Date();
timer.first = false;
}
timer.running = true;
time(timer);
}
}
function stopTime(timer){

var newTimer = new Timer();

newTimer.Doc = "Test's Dossier";
newTimer.save();
alert("yay");

//var t = setTimeout(time(timer), 10);
}
}
function checkTime(i) {
if (i < 10) {i = "0" + i}; // add zero in front of numbers < 10
return i;
}
function init(timer){
var name = "#timer" + timer.id;
var $time = $('' + name)
$time.html("" + timer.h + ":" + timer.m + ":" + timer.s);

var t = timers[i];
stopTime(t);
}
}
function add(){
stopAll();
var number = timers.length + 1;
var starttext = '"start"';
var savetext = '"save"';
var stoptext = '"stop"';
var newTimer = new timer(number);
timers.push(newTimer);
$('#timers').append("<br/>" +
"<h1>Timer " + number + "</h1>" +
"<div id=" + 'timer' + number + ">Test</div>" +
"<button onclick='action(" + number + ", " + starttext + ")" + "'>Start</button>" +
"<button onclick='action(" + number + ", " + stoptext + ")" + "'>Stop</button>" +
"<button onclick='add()'>Add</button>" +
"<button onclick='action(" + number + ", " + savetext + ")" + "'>Save</button>" +
"<p class='description' id='" + 'desc' + number + "'>Click here to enter a description</p>");
$(".description").click(function(){
var text = prompt("Please enter your description here");
if(text === ""||text === null) {
$(this).html("Click here to enter a description");
}else{
$(this).html(text);
timers[number - 1].desc = text;
}
});
init(newTimer);
setTimeout(startTime(newTimer));
}
Save is the function that I have problems with.

You cannot make client side Javascript and server side Javascript coexist at the same file. Jquery/HTML code runs inside a browser and nodejs/express runs inside a server.

Javascript error after upgrade to Drupal 7

I posted a similar question at the Drupal Forum, but I haven't had much luck.
I'm upgrading a site from D6 to D7. So far it's gone well, but I'm getting a Javascript error that I just can't pin down a solution for.
This is a cut down version of the whole script:
(function($) {
function sign(secret, message) {
var messageBytes = str2binb(message);
var secretBytes = str2binb(secret);
if (secretBytes.length > 16) {
secretBytes = core_sha256(secretBytes, secret.length * chrsz);
}
var ipad = Array(16), opad = Array(16);
for (var i = 0; i < 16; i++) {
ipad[i] = secretBytes[i] ^ 0x36363636;
opad[i] = secretBytes[i] ^ 0x5C5C5C5C;
}
var imsg = ipad.concat(messageBytes);
var ihash = core_sha256(imsg, 512 + message.length * chrsz);
var omsg = opad.concat(ihash);
var ohash = core_sha256(omsg, 512 + 256);
var b64hash = binb2b64(ohash);
var urlhash = encodeURIComponent(b64hash);
return urlhash;
}
function addZero(n) {
return ( n < 0 || n > 9 ? "" : "0" ) + n;
}
Date.prototype.toISODate =
new Function("with (this)\nreturn " +
"getFullYear()+'-'+addZero(getMonth()+1)+'-'" +
"+addZero(getDate())+'T'+addZero(getHours())+':'" +
"+addZero(getMinutes())+':'+addZero(getSeconds())+'.000Z'");
function getNowTimeStamp() {
var time = new Date();
var gmtTime = new Date(time.getTime() + (time.getTimezoneOffset() * 60000));
return gmtTime.toISODate() ;
}
}(jQuery));
The part that keeps throwing an error I'm seeing in Firebug is at:
Date.prototype.toISODate =
new Function("with (this)\n return " +
"getFullYear()+'-'+addZero(getMonth()+1)+'-'" +
"+addZero(getDate())+'T'+addZero(getHours())+':'" +
"+addZero(getMinutes())+':'+addZero(getSeconds())+'.000Z'");
Firebug keeps stopping at "addZero is not defined". JS has never been my strong point, and I know some changes have been made in D7. I've already wrapped the entire script in "(function($) { }(jQuery));", but I must be missing something else. The same script works perfectly on the D6 site.
Here is the "fixed" version of the whole code with #Pointy suggestion added. All I left out is the part of the script for making the hash that goes to Amazon, and some of my declared variables.

Here's a better version of your code:
Date.prototype.toISODate = function() {
function addZero(n) {
return ( n < 0 || n > 9 ? "" : "0" ) + n;
}
var d = this;
return d.getFullYear() + '-' +
addZero(d.getMonth() + 1) + '-' +
addZero(d.getDate()) + 'T' +
addZero(d.getHours()) + ':' +
addZero(d.getMinutes()) + ':' +
addZero(d.getSeconds()) + '.000Z';
};
That moves "addDate" inside the extension function, and it avoids the horrid with statement.
