I am new to Javascript. Below is simple program where I am trying to display elements from array that I have created. It does not work. Can anybody please let me know what I am doing wrong?

while (num >= i){
if (num % i == 0){
primefacts.push(i);

replace:-
if (primefacts.length = 0) {
with
if (primefacts.length == 0) {
you are setting the length to 0 instead of comparing.
function findPrimeFactors() {
var primefacts = [];
var primefacs;
var unum = prompt("Please enter a positive number");
var i = 2;
var num = parseInt(unum);

Very new to JavaScript, the first programming language I learned was Java. I am trying to make a simple website that displays the shortest distance between an infinite number of points using prompt boxes and a 2D array.
This code works as expected, however when one of the points has a negative number in it, nothing ever displays for an answer, throwing the error:
Uncaught TypeError: Cannot read property '0' of undefined
at run (index.html:54)
at HTMLButtonElement.onclick (index.html:63)
Google Chrome highlights the error at this line:
toRun = "Shortest distance is " + min + " with these points: (" + finalPoints[0][0] + ", " + finalPoints[1][0] + ") and (" + finalPoints[0][1] + ", " + finalPoints[1][1] + ").";
How can I get this program to work with negative numbers as well?
function run() {
var x, y;
var finalPoints = [];
var min = 0;
var toRun;
var temp;
var list = []; //using 2d array to store points
while (true) {
x = prompt("Enter an X-Value: ");
if (x == null || x == "") {
break;
}
y = prompt("Enter a Y-Value: ");
if (y == null || y == "") {
break;
}
list.push([x, y]);
}
if (list.length < 2) {
toRun = "Sorry, you didn't enter enough points for this program to run correctly. Please try again.";
} else if (list.length == 2) {
toRun = "Distance between points (" + list[0][0] + ", " + list[0][1] + ") and (" + list[1][0] + ", " + list[1][1] + ") is " + Math.sqrt(Math.pow((list[0][0] - list[1][0]), 2) + Math.pow((list[0][1] - list[1][1]), 2));
} else {
min = Math.sqrt(Math.pow((list[0][0] - list[1][0]), 2) + Math.pow((list[0][1] - list[1][1]), 2));
for (var i = 0; i < list.length; i++) {
for (var j = 0; j < list.length; j++) {
temp = Math.sqrt(Math.pow((list[i][0] - list[j][0]), 2) + Math.pow((list[i][1] - list[j][1]), 2));
if (temp < min && temp != 0) {
min = temp;
finalPoints.push([list[i][0], list[j][0]]);
finalPoints.push([list[i][1], list[j][1]]);
}
}
}
toRun = "Shortest distance is " + min + " with these points: (" + finalPoints[0][0] + ", " + finalPoints[1][0] + ") and (" + finalPoints[0][1] + ", " + finalPoints[1][1] + ").";

I'm working on a somewhat simply dice game but I can't get it to display the alert popup when I click the button.
I'm also trying to figure out the simplest way to check if housescore or myscore = maxscore then alert "congratulations, you win" or "sorry, you lost"
Here is my code:
var myscore = 0;
var maxScore = 100;
var housescore = 0;
function rollDice() {
var x = Math.floor(Math.random() * 6) + 1;
var y = Math.floor(Math.random() * 6) + 1;
if (x + y == 7 || 11) {
housescore = (housescore + 10);
alert("CRAPS" + " Your Score is " + "Player: " + myscore + "House: " + housescore);
} else if (x == y && x + y == isEven(n)) {
myscore = (myscore + 10);
alert("Even Up" + " Your Score is " + "Player: " + myscore + "House: " + housescore);
}
if (x == y && x + y == isOdd(n)) {
housescore = (housescore + 10);
alert("Odd Ball" + " Your Score is " + "Player: " + myscore + "House: " + housescore);
} else {
alert("You rolled a " + x + " and a " + y + " Your Score is " + "Player: " + myscore + "House: " + housescore);
}
}
function isEven(n) {
return n % 2 == 0;
}
function isOdd(n) {
return Math.abs(n % 2) == 1;
}
<input type="button" value="Roll The Dice" onClick="rollDice()" />
This is what I think you're after. I broke down your ifs to handle both cases where x == y in one branch, and used a simple mod operation to determine whether a die roll was even, and an else to handle the odd die rolls.
var myscore = 0;
var maxScore = 100;
var housescore = 0;
function rollDice() {
var x = Math.floor(Math.random() * 6) + 1;
var y = Math.floor(Math.random() * 6) + 1;
var total = x + y;
msg = "You rolled " + x + "," + y + " = " + total + "\n";
if (total == 7 || total == 11) {
housescore += 10;
msg += "CRAPS";
} else if (x == y) { // this condition contains two possible outcomes, handle both within this else if
if (x % 2 == 0) {
myscore += 10;
msg += "Even Up";
} else {
housescore += 10;
msg += "Odd Ball";
}
}
msg += " Your Score is " + "Player: " + myscore + ", House: " + housescore;
alert(msg);
}

Code like this is wrong:
if (x == y && x + y == isEven(n))
You haven't declared an n variable. And it makes no sense to compare the addition of two numbers to the true or false value that isEven() and isOdd() return. I think what you meant was:
if (x == y && isEven(x + y))
But when the two numbers are equal, adding them together will always be even, so I'm not sure what the point of that test is. Maybe you mean:
if (x == y && isEven(x))
I'm not familiar with a rule in Craps where the house or player win depending on whether equal dice are even or odd.
This is also wrong:
if (x == 7 && y == 11)
x and y are numbers from 1 to 6, so they can't be 7 or 11. In craps you add the two dice, so this should be:
if (x + y == 7 || x + y == 11)
There's little need for both isEven() and isOdd() functions -- a number is odd if it's not even.

But it dosen't work. Any help?
P.S. My teacher assigned this to me. Please respond as soon as possible. Thanks.
This code is a complete mess. I dont know where it comes from, but definitely not Javascript.
Try the following instead:

Well, you could do this:
var type = (Math.floor(Math.random(4));
var ret = 0;
var n = [(Math.floor(Math.random(100)), (Math.floor(Math.random(100))];
if (type == 0) ret = n[0] + n[1]
else if (type == 1) ret = Math.abs(n[0] - n[1])
else if (type == 2) ret = n[0] * n[1];
else if (type == 3) ret = n[0] / n[1]
else ret = n[0] / 5 % n[1]
// do something with ret
It's fully expandable, just edit n and the if statements
I can't figure this out I keep getting stuck in a loop. I don't know if I have my calculation or if statements in the right areas, please I could use some help. My output is like a end of day report. I could really use the help.

To preface this, we are a small organization and this system was built by someone long ago. I am a total novice at javascript so I have trouble doing complicated things, but I will do my best to understand your answers. But unfortunately redoing everything from scratch is not really an option at this point.
We have a system of collecting data where clients use a login to verify a member ID, which the system then uses to pull records from an MS Access database to .ASP/html forms so clients can update their data. One of these pages has the following function that runs on form submit to check that data in fields a/b/c sum to the same total as d/e/f/g/h/i. It does this separately for each column displayed (each column is a record in the database, each a/b/c/d/e/f is a field in the record.)
The problem is with this section of the function:
for (var j=0; j<recCnt; j++) {
sumByType = milesSurf[j] + milesElev[j] + milesUnder[j];
sumByTrack = milesSingle[j] + milesDouble[j] + milesTriple[j] + milesQuad[j] + milesPent[j] + milesSex[j];
etc.
It should use javascript FOR to loop through each record and test to see if they sum to the same thing.
In Firefox and IE this is working properly; the fields sum properly into "sumByType" and "sumByTrack". You can see below I added a little alert to figure out what was going wrong:
alert(sumByType + " " + j + " " + recCnt + " " + milesSurf[j] + " " + milesElev[j] + " " + milesUnder[j]);
In Chrome, that alert tells me that the components of "sumByType" and "sumByTrack" (the various "milesXXXXX" variables) are undefined.
My question is: Why in Chrome is this not working properly, when in IE and FFox it is? Any ideas?
Full function code below:
function submitCheck(formy, recCnt) {
//2/10/03: added milesQuad
//---------------checks Q#4 that Line Mileage by type is the same as by track
var milesElev = new Array();
var milesSurf = new Array();

var j = 0; var sumByTrack = 0; var liney; var yrOp;
//var str = "document.frm.milesElev" + j;
//alert(str.value);
for (var i in document.frm) {

I think for (var i in document.frm) is the problem. You should not enumerate a form element, there will be plenty of unexpected properties - see Why is using "for...in" with array iteration a bad idea?, which is especially true for array-like objects. I can't believe this works properly in FF :-)
Use this:
var ele = document.frm.elements; // or even better document.getElementById("frm")
for (var i=0; i<ele.length; i++) {
// use ele[i] to access the element,
// and ele[i].name instead of i where you need the name
}
Also, you should favour a loop over those gazillion of if-statements.
