Javascript 測驗：單擊下一個按鈕時無法激活下一個問題

Question

我剛剛開始學習 Vanilla JS，我正在使用 API 進行測驗，我需要你的幫助！

我希望能夠單擊“下一步按鈕”並出現下一個問題，但我無法訪問 API 問題。

希望這是有道理的。 如果需要進一步說明，請告訴我！ 謝謝！

 let apiUrl = " https://opentdb.com/api.php?amount=150"; function showQuestion(response) { console.log(response); console.log(response.data.results[0].question); let question = document.querySelector("#question"); question.innerHTML = response.data.results[0].question; } axios.get(apiUrl).then(showQuestion); function showNextQuestion(response) { console.log(response.data.results); } function nextQuestion() { let apiUrl = " https://opentdb.com/api.php?amount=150"; axios.get(apiUrl).then(showNextQuestion); } let nextButton = document.querySelector("#next"); nextButton.addEventListener("click", nextQuestion);

打電話后

axios.get(apiUrl).then(showQuestion);

你有 150 個問題。 只需將結果存儲到 function

let questions = [];
axios.get(apiUrl).then(function(response) {
    questions = response.data.results;
});

然后添加全局計數器

let questionIndex = 0;

並與之合作

function showNextQuestion() {
  console.log(questions[questionIndex]);
}

function nextQuestion() {
  questionIndex++;
  showNextQuestion();
}

結果：

let apiUrl = " https://opentdb.com/api.php?amount=150";

let questions = [];
let questionIndex = 0;

axios.get(apiUrl).then(function(response) {
    questions = response.data.results;
});


function showQuestion() {
  let question = document.querySelector("#question");
  question.innerHTML = questions[questionIndex];
}

function nextQuestion() {
  questionIndex++;
  showQuestion();
}

let nextButton = document.querySelector("#next");
nextButton.addEventListener("click", nextQuestion);
