I want to store what is being clicked on, so that it can be used for multiple times in a game of rock-paper-scissors. I need to use this until player or computer scores 5. Any suggestions will be appreciated!
HTML file:
<div class = buttons>
<button id="rock">Rock</button>
<button id="paper">Paper</button>
<button id="scissors">Scissors</button>
</div>

I am able to log the button.id however it's not useful as I'm unable to use it in any other functions.
const buttons = document.querySelectorAll('button');
buttons.forEach(button => button.addEventListener('click', () => {
console.log(button.id)})); //get the button.id
const buttons = document.querySelectorAll('button');
buttons.forEach(button => button.addEventListener('click', () => {
const {id} = button
playerChoices.push(id)
handleChoice(id)
})
);
const handleChoice = id => {
console.log(id)
console.log(playerChoices)
}
I want to use it in this function :game() but I am unable to call the id value, I also tried playerSelection = playerChoices[playerChoices.length - 1]; to take the last element of the array but it errors to "undefined" every time in this function.
function game(){
let playerScore = 0;
let computerScore = 0;
// playRound()
// until player or computer scores 5
while (playerScore < 5 && computerScore < 5) {
const playerSelection = **UNDEFINED**;
const computerSelection = counterPlay();
let roundResult = playRound(playerSelection, computerSelection);
console.log(playRound(playerSelection, computerSelection));
console.log("You chose: ", playerSelection, "Computer chose: " ,computerSelection);
//incrementing the score:
if(roundResult.search('You win') > -1){
playerScore++;
} else if (roundResult.search('You loose') > -1){
computerScore++;
}
console.log("you : ",playerScore , "computer : " , computerScore);
if(computerScore == 5){
console.log("You lost :( I won");
}
else if(playerScore == 5){
console.log("I lost, you're too good. Congrats on the win!")
}
}
}
How do I store the id to playerSelection every time I click ?

You can just store it in an array or pass it to a function
like this
let playerWins = 0
let computerWins = 0
const choices = ['Rock', 'Paper', 'Scissors']
const buttons = document.querySelectorAll('button');
buttons.forEach(button => button.addEventListener('click', () => {
const {
id
} = button
playMatch(id, Math.floor(Math.random() * choices.length))
}));
const startGame = () => {
let playerWins = 0
let computerWins = 0
}
const playMatch = (playerChoice, computerChoice) => {
const result = (choices.length + playerChoice - computerChoice) % choices.length
let message
switch (result) {
case 0:
message = `it's a draw`
break;
case 1:
message = `You won ${choices[playerChoice]} beats ${choices[computerChoice]}`
playerWins++;
break;
default:
message = `You lose ${choices[computerChoice]} beats ${choices[playerChoice]}`
computerWins++;
}
console.log(message)
if (Math.max(playerWins, computerWins) === 5) {
alert('game ended')
}
}<div id="buttons">
<button id="0">Rock</button>
<button id="1">Paper</button>
<button id="2">Scissors</button>
</div>
<div id="scores"></div>var turns = [];
const buttons = document.querySelectorAll('button');
buttons.forEach(button => button.addEventListener('click', (event)=>{
console.log(event.target.id);
console.log(button.id);
turns.push(button.id);
console.log(turns);
}));
you are missing one ) of foreach loop and the button.id will then work always use browser console to check for syntax or script errors.
