자바스크립트 활용편 -퀴즈이펙트 만들어보기

퀴즈 프로그램

웹디자인기능사 자격증을 준비하면서 퀴즈가 나오는 프로그램를 구현하였습니다.

자바스크립트-객관식

"정답 확인하기" 버튼을 누르면 답이 나오도록 구성하였습니다.

js

//선택자
const quizType = document.querySelector( ".quiz__type" ); //퀴즈종류
const quizNumber = document.querySelector( ".quiz__question .number"); //퀴즈번호
const quizAsk = document.querySelector( ".quiz__question .ask"); //퀴즈 질문
const quizConfirm = document.querySelector( ".quiz__answer .confirm") //정답확인버튼
const quizResult = document.querySelector( ".quiz__answer .result") // 정답 결과
const quizDog = document.querySelector( " .quiz__view .dog")  //강아지

//문제 정보
const answerType = "웹디자인기능사";
const answerNum = "1";
const answerAsk =   "인접하는 두 색의 경계 부분에 색상, 명도, 채도의 대비가 더욱 강하게 일어나는 현상을 무엇이라고 하는가?"
const answerResult = "연변대비"

//정답 숨기기
quizResult.style.display = "none";


//문제 출력
quizType.innerText = answerType;
// quizType.innerHtml 태그인식함
quizNumber.innerText = answerNum + ". ";
quizAsk.innerText = answerAsk;
quizResult.textContent = answerResult;  //textContent와 innerText는 같지만 익스플로러 때문에 생긴 문제이다.


//정답 확인
//정답 버튼을 클릭하면 확인버튼 안보이게.. 숨겨진 정답은 보이게..
//정답을 확인하면 강아지가 웃고 있어야한다.  클래스 like 추가
quizConfirm.addEventListener("click", function(){
    quizConfirm.style.display = "none";    //버튼을 누르면 정답버튼을 없애기
    quizResult.style.display = "block";
    quizDog.classList.add("like");    //class를 추가해준다.
})
