javascript - 提交后如何显示一个部分

Question

我试图在提交后显示结果框。如您所见，我有一个包含测验名称的部分和另一个包含问题列表的部分，其余部分是结果框。我希望在提交之前，旧屏幕包含测验的名称并且不显示结果框。选择并提交后，测验名称部分一直停留在屏幕上，问题列表变为禁用，结果框将出现在新屏幕上。

我怎样才能做到这一点？非常感谢。

/* the question list disapper */

    const disapp = event.currentTarget;
    disapp.removeEventListener("click", disappear);

    const startquiz = document.querySelector("#introduction");

    startquiz.classList.add("hidden");
    quizlist.classList.remove("hidden");

    const questionlist = document.querySelector("#attempt-quiz");
    questionlist.scrollIntoView();
}
const disapp = document.querySelector("#introduction button");
disapp.addEventListener("click", disappear);

/* click to any of the answer */

function openPresent(event) {
    const answer = document.querySelectorAll(".option");
    for (let i = 0; i < answer.length; i++) {
        answer[i].style.backgroundColor = originalAnswerArray[i];
    }
    const input = event.target.querySelector("input")
    input.checked = true;
    event.target.style.backgroundColor = "blue";
