Is there a way to keep a variable that a generate using Math.random when I run the function multiple times - javascript

I am trying to make a game when you have to guess a number that is generated by the Math.random() function in JavaScript. But I realized that when I do that I have to rerun the function if they get the number wrong. Then the number regenerates when it reruns the function. Is there a way that I can make the variable stay until I want to change it. I was going to change it using the const function but I realized it would do the same thing. Here is my full code:
var tries = 5;
var howMany = 0;
var wrong = 0;
var player1 = 0;
var player2 = 0;
var triesmulti = 10;
var turn = 'player 1';
var number;
function start() {
var min = document.getElementById('min').value;
var max = document.getElementById('max').value;
number = Math.floor(Math.random() * (+max - +min)) + +min;
if (tries < 1) {
alert('You \don\'t have any more tries left. The number was \n' + number);
tries = 5;
wrong += 1;
document.getElementById('wrong').innerHTML = 'You have got the number wrong ' + wrong + ' times';
} else {
var guess = prompt();
if (guess == number) {
alert('You got the number right!\n' + number);
howMany += 1;
tries = 5;
document.getElementById('howMany').innerHTML = 'You have guessed the number ' + howMany + ' times';
document.getElementById('tries').innerHTML = 'You have 5 tries left';
} else {
alert('You got the number wrong.');
tries -= 1;
document.getElementById('tries').innerHTML = 'You have ' + tries + ' tries left';
setTimeout(start, 1000);
}
}
}
function multiplayer() {
var min = document.getElementById('minm').value;
var max = document.getElementById('maxm').value;
number = Math.floor(Math.random() * (+max - +min)) + +min;
if (triesmulti < 1) {
alert('You \don\'t have any more tries left\n' + number);
triesmulti = 10;
document.getElementById('triesmulti').innerHTML = 'You have 5 tries for each player';
} else {
var guess = prompt(turn);
if (turn == 'player 1') {
if (guess == number) {
alert('You got the number right!\n' + number);
player1 += 1;
triesmulti = 10;
document.getElementById('triesmulti').innerHTML = 'You have 5 tries for each player';
} else {
alert('You got the number wrong!');
turn = 'player 2';
setTimeout(multiplayer, 1000);
}
} else if (turn == 'player 2') {
if (guess == number) {
alert('You got the number right!\n' + number);
player2 += 1;
triesmulti = 10;
document.getElementById('triesmulti').innerHTML = 'You have 5 tries for each player';
} else {
alert('You got the number wrong!');
turn = 'player1';
setTimeout(multiplayer, 1000);
}
}
}
}
If you see there, in the setTimeout() it reruns the function.


You can create a stateful random number generator quite easily with an object or closure:
const rndRng = (lo, hi) => ~~(Math.random() * (hi - lo) + lo);
const intRng = (lo, hi) => {
let n = rndRng(lo, hi);
return {
next: () => (n = rndRng(lo, hi)),
get: () => n
};
};
const rng = intRng(10, 20);
console.log(rng.get());
console.log(rng.get());
rng.next();
console.log(rng.get());
console.log(rng.get());
But having to do this shouldn't really be necessary for your application. Currently, the application uses non-idempotent functions that rely on global state, repeated/duplicate logic and deeply nested conditionals, so it's become too encumbered to easily work with.
I'd start by storing state in an object. A game like this can be modeled well by a finite state machine.
The below code is a naive implementation of this with plenty of room for improvement, but hopefully demonstrates the idea. It works for any number of players and it's fairly easy to add features to.
However, string messages are baked into business logic so the class is overburdened. A good next step would be creating a separate view class to abstract business logic from display. However, although the message strings are baked into the game logic, the DOM is decoupled. This makes it fairly easy for the caller to use the class in other UIs such as substituting the DOM for alert/prompt.
The below solution is far from the only way to approach this design problem.
class GuessingGame {
constructor(players=1, guesses=5, lo=0, hi=10) {
this.players = Array(players).fill().map(() => ({
guesses: guesses, score: 0
}));
this.guesses = guesses;
this.lowerBound = lo;
this.upperBound = hi;
this.state = this.initialize;
}
initialize() {
const {lowerBound: lo, upperBound: hi} = this;
this.players = this.players.map(({score}) => ({
guesses: this.guesses,
score: score
}));
this.target = ~~(Math.random() * (hi - lo) + lo);
this.currentPlayer = ~~(Math.random() * this.players.length);
this.state = this.guess;
this.message = `guess a number between ${lo} and ${hi - 1} ` +
`(inclusive), player ${this.currentPlayer}:`;
}
handleCorrectGuess() {
this.state = this.initialize;
this.players[this.currentPlayer].score++;
this.message = `player ${this.currentPlayer} guessed ` +
`${this.target} correctly! press 'enter' to continue.`;
}
handleNoGuessesLeft(guess) {
this.state = this.initialize;
this.players[this.currentPlayer].score--;
this.flash = `${guess} was not the number, player ` +
`${this.currentPlayer}.`;
this.message = `player ${this.currentPlayer} ran out of ` +
`guesses. the secret number was ${this.target}. press ` +
`'enter' to continue.`;
}
handleIncorrectGuess(guess) {
this.flash = `${guess} was not the number, player ` +
`${this.currentPlayer}.`;
this.currentPlayer = (this.currentPlayer + 1) % this.players.length;
const {lowerBound: lo, upperBound: hi} = this;
this.message = `guess a number between ${lo} and ${hi - 1} ` +
`(inclusive), player ${this.currentPlayer}:`;
}
guess(guess) {
if (String(+guess) !== String(guess)) {
this.flash = `sorry, ${guess || "that"} ` +
`isn't a valid number. try something else.`;
return;
}
if (this.target === +guess) {
this.handleCorrectGuess();
}
else if (!--this.players[this.currentPlayer].guesses) {
this.handleNoGuessesLeft(+guess);
}
else {
this.handleIncorrectGuess(+guess);
}
}
nextState(...args) {
this.flash = "";
return this.state(...args);
}
scoreBoard() {
return game.players.map((e, i) =>
`player ${i}: {score: ${e.score}, guesses remaining: ` +
`${e.guesses}} ${game.currentPlayer === i ? "<--" : ""}`
).join("\n");
}
}
const msgElem = document.getElementById("message");

const scoresElem = document.getElementById("scoreboard");
const game = new GuessingGame(3);

Well, your code is not organised, have lot of duplicates, you could devide it into functions anyway, you can add a boolean variable to check against when you should change the number, I don't know about your HTML code or css but I just added those elements according to you selectors, you can change the multiplayer function too.
var tries = 5;
var howMany = 0;
var wrong = 0;
var player1 = 0;
var player2 = 0;
var triesmulti = 10;
var turn = 'player 1';
var number;
var isAlreadyPlaying = false;
function start() {
var min = document.getElementById('min').value;
var max = document.getElementById('max').value;
if(!isAlreadyPlaying) {
isAlreadyPlaying = true;
number = Math.floor(Math.random() * (+max - +min)) + +min;
}
if (tries < 1) {
alert('You \don\'t have any more tries left. The number was \n' + number);
tries = 5;
wrong += 1;
document.getElementById('wrong').innerHTML = 'You have got the number wrong ' + wrong + ' times';
isAlreadyPlaying = false;
} else {
var guess = prompt();
if (guess == number) {
alert('You got the number right!\n' + number);
howMany += 1;
tries = 5;
document.getElementById('howMany').innerHTML = 'You have guessed the number ' + howMany + ' times';
document.getElementById('tries').innerHTML = 'You have 5 tries left';
isAlreadyPlaying = false;
} else {
alert('You got the number wrong.');
tries -= 1;
document.getElementById('tries').innerHTML = 'You have ' + tries + ' tries left';
setTimeout(start, 1000);
}
}

Give 1 point to each unique winner respectively in javascript

First of all, I hope you can understand my English. I'm not really good at English. I'd like to ask for help on giving 1 point to every unique user(a user that joined, a live stream to be exact) for every correct answer.
The issue I have in the current coding is that instead of giving points to each user respectively, it counts all users as one. What I mean by that is, for example: When user A wins, he gets(displays) 1 point. When user B wins, he gets(displays) 2 points. The points keep adding for every other user.
I'd like it to be like this: When user A wins, he gets(displays) 1 point. When user B wins he also gets(displays) 1 point too. That means each user has their own winning record.
I hope you can understand what I'm trying to explain.
Please ask if you need further explanation on things you don't understand.
I'd like to display the win count under/currently under the 'function addPhoto'.
Following is the current code:

You should have an dictionary (object) of wins with keys the users, and values are the wins for each. Thus you save for each user its own wins.
So declare global:
let wins = {
// name: wins, name2: wins2
}
Then whenever need to increase wins, do so for the wins[playerName] value.
if (mode == "winner") {
wins[userName] = wins[userName] || 0
wins[userName]++
addContent(
`<div style="text-align:center;font-size: 1.25rem;">
<div style='padding-bottom:.25rem;color:#1881FF;'>👏🏻👏🏻 `+ words + `</div>
<div style='padding-bottom:.5rem;font-weight: bold;color:#20B601;'>`+ userName + ` ❗</div>
<div>
<img src="`+ userAvatar + `" style="width:135px;height:135px;border-radius: 15px;"/>
Wins: `+ wins[userName] + `
</div>
</div>`
);

I am using a player object (playerObject) that has properties and is changed constantly. I initialize with 4 playerObjects with their own properties and name.
This is a clone of the board game monopoly.
When a player lands on a property and checks function canIBuy() and they buy it, it purchases that property for every player. Why is this happening?
Posting all the JS code in case there is something i am missing, although this is the broken part.
Player lands on space
checks isProperty()
if property, runs canIBuy()
buys it if its available and they have the cash

How to display a div with random ID without repeating it using jQuery?

I have a function to select a random number from 0 to 45 and then I show the div with the specific ID. It's working fine but it repeats a number.
Can anyone advise so it won't repeat numbers?
I call the function onclick like this
$(".skip").click(function () {
scared++;
$("#counter").html("My current count is: " + dared);
var d = 50;
/*$(".question").addClass("hideMe");
$(this).parents("div").next("div").removeClass("hideMe");*/
var r = Math.round(Math.random() * 44) + 1;
var newquestion = "q" + r;
$('.active').removeClass("active");
$("#" + newquestion).addClass("active");
if (scared > 44) {
$('.main').fadeOut('fast');
$('.logo').switchClass("logo", "share");
$('.progress').css("display", "none");
$('.share-game').css("display", "block");
$('.hero').css("right", "-240px");
$('#score-total').html(score + '');
} else {
}
$('.red-line').append('<div id="children' + (d++) + '" class="red"></div>');
return false;
});

You can see what i did.
var usedNumbers = [];
var randomNumbers = [];
$(function() {
//Getting 20 random numbers
for (i = 0; i < 20; i++) {
randomNumbers.push(getRandomNumber());
}
console.log(randomNumbers);
function getRandomNumber() {
var hasInArray = true;
do {
var r = Math.round(Math.random() * 44) + 1;
if (usedNumbers.indexOf(r) === -1) {
usedNumbers.push(r);
hasInArray = false;
return r;
}
} while (hasInArray === true);
}
});
Warning to not set the numbers of randomnumbers more then what you want to get, because that will cause an infinite loop!

Use an array to capture the used numbers and then check that array on each click, generating a new number if that one is found. It resets back to an empty array when it is full.
var savedNumbers = [];
function getRandom() {
if (savedNumbers.length === 45) {
savedNumbers = [];
}
var r = Math.round(Math.random() * 44) + 1;
if (savedNumbers.indexOf(r) > -1) {
getRandom();
} else {
savedNumbers.push(r);
return r;
}
}

How to submit the value of an input field?

I have a math game that works partially. What I need to have happen is to take the values of the divs (one is x and the other is y), type in the answer of those two multiplied, be able to submit it and refresh to solve another.
Any help would be much appreciated!
http://jsfiddle.net/justinw001/Mttw6/11/
<script type="text/javascript">
function myFunction() {
score = 0;
var number = document.getElementById('inputElement').value;
questionAmount = number;
for(i = 0; i < questionAmount; i++) {
var x = Math.floor(Math.random() * 13);
var y = Math.floor(Math.random() * 13);
$('#input1').text(x);
$('#input2').text(y);
<!-- question = prompt('What is ' + x + ' * ' + y + ' = ?'); -->
question = document.getElementById('answer').value;
if(question == null || isNaN(question)) {
break;
}
if(question == x * y) {
score++;
}
}
alert('You got ' + score + ' out of ' + questionAmount + ' correct.');
}
</script>

Try to bind the process with your buttons. Clicking the left button, produce the questions.
And Clicking the right one, verify the answer.
Demo: Fiddle
var score = 0;
var questions = [];
// Generate questions
$('#gen').click(function () {
score = 0;
questions = [];
var questionAmount = parseInt($('#inputElement').val(), 10);
for (var i = 0; i < questionAmount; i++) {
var q = {
x: Math.floor(Math.random() * 13),
y: Math.floor(Math.random() * 13)
};
questions.push(q);
}
nextQuest(questions.pop());
});
// Verify the answer
$('#sub').click(function () {
var ans, x, y;
if (questions.length >= 0) {
ans = parseInt($('#answer').val(), 10);
x = parseInt($('#input1').text(), 10);
y = parseInt($('#input2').text(), 10);
if (ans === x * y) {
score++;
nextQuest(questions.pop());
} else {
alert('err');
}
}
});
var nextQuest = function (q) {
if (q) {
$('#input1').text(q.x);
$('#input2').text(q.y);
$('#answer').val('');
$('#inputElement').val(questions.length);
} else {
$('#input1, #input2').text('');
$('#answer, #inputElement').val('');
alert(score);
}
};
