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{
/*

If..else condition error

I am trying to figure out what is wrong with this following code. The code searches for value in a table and assigns mxCost. The IF..ELSE condition works for all values except 1 and is also reading the table. The IF condition makes the page crash and i am not able to figure out why? Can someone please help me figure out what i am doing wrong here. Any help will be appreciated. Thank you.
$jq("#airTableValues tbody tr").each(function() {
var monthName = months[parseInt(dateSplit[1])-1]+" "+dateSplit[0];
if(monthName==$jq(this).find("td:eq(0)").text().trim())
{
mxCost = $jq(this).find("td:eq(6)").text().trim();
}
});
if (mxCost)
mxCost = (mxCost.substring(1, mxCost.length));
else {
mxCost = 0;
}
var MxStat = document.getElementById("MxStat").value;
MxStat = MxStat/100;
var InflationRate1 = document.getElementById("InflationRate1").value;
InflationRate1 = InflationRate1/100;
var rate3 = document.getElementById("rate3").value;
rate3 = Math.pow(1+rate3/100,1/365)-1;
var mxAdj;
if (MxStat == 1){
mxAdj = mxCost;
} // <------- NOT WORKING!
else if (MxStat != 1) {
var TotalCost = mxCost * 2;
mxAdj = (TotalCost * MxStat) - mxCost;
}
var ReturnVal = (mxAdj * InflationRate1) + mxAdj;
var ReturnCalc = ReturnVal * 1000000;
var ReturnPV = Math.floor(ReturnCalc/Math.pow(1+rate3,periods));
document.getElementById("ReturnCondition").value =
(ReturnPV/1000000).toFixed(2);
ReturnCondition = ReturnVal.toFixed(2);

This worked for me
if (MxStat != 1){
var mxAdj = (TotalCost * MxStat) - mxCost;
var ReturnVal = (mxAdj * InflationRate1) + mxAdj;
aReturnCondition = ReturnVal.toFixed(2);
}
if (MxStat == 1){
var mxAdj = mxCost;
var ReturnVal = (mxAdj * InflationRate1) + mxAdj;
aReturnCondition = parseFloat(ReturnVal).toFixed(2);}

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');

this.id = id;
this.running = false;

var newTimer = new timer(number);
timers.push(newTimer);

$(".description").click(function(){
var text = prompt("Please enter your description here");
if(text === ""||text === null) {

}else{
$(this).html(text);

}
});

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.
Reference to Client-Server concept

Some good reference to work with NodeJS

whats selution code for draw poll bar?

this my code in java script :
function DrawPollBars(BarVar, BarWidth) {
var newbar = new Array();
newbar = BarVar;
var newWidth = new Array();
newWidth = BarWidth;
var IncVa;
TotalVotes = sum(BarVar, BarWidth);
IncVal = parseFloat(TotalVotes / 10);
//var percent = 0.00; var count = 0;
var NewBarWidthb = new Array();
var BarNextVar = new Array();
//NewBarWidth = "NewBarWidth" + x;
NewBarWidthb[x] = 0;
//NewBarWidthb[x] = NewBarWidth;
for (var x = 1; x < BarWidth.length; x++) {
var PollBar = document.getElementById('PollBar' + x);
var PollRate = document.getElementById('PollRate' + x);
if (parseInt(parseInt(BarVar[x]) * 200 / TotalVotes) > 0) NewBarWidthb[x] = parseInt(BarVar[x]) * 200 / TotalVotes;
else if (BarVar[x] >= 0) NewBarWidthb[x] = 1;
else NewBarWidthb[x] = 0;
var pollbar = PollBar.style.width = NewBarWidthb[x] + 'px';
var pollrate = PollRate.innerHTML = parseFloat(BarVar[x]).toFixed(0) + " (" + parseFloat(parseFloat(BarVar[x]) / TotalVotes * 100).toFixed(1) + "%)";
//percent = parseFloat(parseFloat(BarWidth[x]) / TotalVotes * 100).toFixed(2) ;
// count = parseFloat(BarWidth[x]).toFixed(0);
if (BarVar != BarWidth) {
if (parseFloat(BarVar[x]) + IncVal <= parseInt(BarWidth[x])) BarNextVar[x] = parseFloat(BarVar[x]) + IncVal; else BarNextVar = BarWidth;
}
}
var ff = window.setTimeout("DrawPollBars([" + BarNextVar + "],[" + BarWidth + "]);", 90);
}
when click btn for first time it is work ok but in second it seems not correctly
i dont know causes

try to use window.clearTimeout(timeoutID); after you complete the action.
For more details you can read here https://developer.mozilla.org/ro/docs/Web/API/window.setTimeout

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.
