JavaScript конец игры, отображение наивысшего балла игроков и наивысшего рейтинга игроков

Question

Я создаю простую JavaScript html игру. просто вопрос и ответ. У игрока есть всего 20 секунд, чтобы ответить на вопросы. Проблема, с которой я столкнулся, заключается в том, что по истечении времени игроки все еще могут отвечать на вопросы, и счет продолжает расти.

Как мне отобразить «Игра окончена» после того, как время истекло. Кроме того, как мне отобразить их счет?

const startButton = document.getElementById('start-btn')
const nextButton = document.getElementById('next-btn')
const questionContainerElement = document.getElementById('question-container')
const questionElement = document.getElementById('question')
const answerButtonsElement = document.getElementById('answer-buttons')

let shuffledQuestions, currentQuestionIndex
let countRightAnswers = 0;

startButton.addEventListener('click', startGame)
nextButton.addEventListener('click', () => {
  currentQuestionIndex++
  setNextQuestion()
}
)
function startGame() {
  startButton.classList.add('hide')
  shuffledQuestions = questions.sort(() => Math.random() - .5)
  currentQuestionIndex = 0
  questionContainerElement.classList.remove('hide')
  countRightAnswers = 0;
  c = 20;
  setNextQuestion()
}

function setNextQuestion() {
  resetState()
  showQuestion(shuffledQuestions[currentQuestionIndex])
}

function showQuestion(question) {
  questionElement.innerText = question.question
  question.answers.forEach(answer => {
    const button = document.createElement('button')
    button.innerText = answer.text
    button.classList.add('btn')
    if (answer.correct) {
      button.dataset.correct = answer.correct
    }
    button.addEventListener('click', selectAnswer)
    answerButtonsElement.appendChild(button)
  })
}

function resetState() {
  clearStatusClass(document.body)
  nextButton.classList.add('hide')
  while (answerButtonsElement.firstChild) {
    answerButtonsElement.removeChild(answerButtonsElement.firstChild)
  }
}

function selectAnswer(e) {
  const selectedButton = e.target
  const correct = selectedButton.dataset.correct
  setStatusClass(document.body, correct)
  Array.from(answerButtonsElement.children).forEach(button => {
    setStatusClass(button, button.dataset.correct)
  })
  if (shuffledQuestions.length > currentQuestionIndex + 1) {
    nextButton.classList.remove('hide')
  } else {
    startButton.innerText = 'Restart'
    startButton.classList.remove('hide')
  }
  if (selectedButton.dataset = correct) {
    countRightAnswers++;
  }
  document.getElementById('score001').innerHTML = countRightAnswers;
}

function setStatusClass(element, correct) {
  clearStatusClass(element)
  if (correct) {
    element.classList.add('correct')
  } else {
    element.classList.add('wrong')
  }
}

function clearStatusClass(element) {
  element.classList.remove('correct')
  element.classList.remove('wrong')
}

function timer001() {
  c = c - 1;
  if (c < 20) {
    time001.innerHTML = c;
  }

  if (c < 1) {
    window.clearInterval(update);
  }
}

update = setInterval('timer001()', 1000);

Answer 1

Чтобы отключить кнопки после истечения таймера:

function timer001() {
  c = c - 1;
  if (c < 20) {
      time001.innerHTML = c;
  }
 
  if (c < 1) 
  {
    window.clearInterval(update);
    
    // get all of the buttons by class
    let buttons = document.getElementsByClassName("btn")
    
    // loop through the array of buttons, set them to be disabled
    for (let i = 0; i < buttons.length; i++) 
    {
       buttons[i].disabled = true
    }   
  }
}

Похоже, ваша игра уже отображает их счет, когда игра окончена, но, возможно, вы могли бы создать всплывающее окно для отображения экрана «Игра окончена».

В качестве альтернативы вы можете использовать JavaScript, чтобы заменить название вопроса на «Game Over»:

function timer001() {
  c = c - 1;
  if (c < 20) {
      time001.innerHTML = c;
  }
 
  if (c < 1) 
  {
    window.clearInterval(update);
    let buttons = document.getElementsByClassName("btn")

    for (let i = 0; i < buttons.length; i++) 
    {
       buttons[i].disabled = true
    }

    // this line below will replace the question with "Game Over!"
    document.getElementById("question").innerHTML = "Game Over!"
  }
}
