我已经创建了很多div,看起来不太好。你有什么建议可以写得更干净吗?例如,我为每个饼类创建了单独的div。有没有更短的方法来做到这一点?或者我可以使用单独的函数,然后再这样做吗?

const arrow = document.querySelector("#arrow");
const callAllPie = document.querySelector(".allPie");
const deleteSkills = document.querySelector("#exit");
eventList();

function eventList() {
  arrow.addEventListener("click", showSkills);
  deleteSkills.addEventListener("click", deleteInfos);
}

function deleteInfos() {
  while (callAllPie.firstElementChild != null) {
    callAllPie.removeChild(callAllPie.firstElementChild);
    if (callAllPie.firstElementChild == null) {
      document.querySelector("#exit").setAttribute("style", "display:none");
      arrow.addEventListener("click", showSkills);
    }
  }
}

function showSkills() {
  arrow.removeEventListener("click", showSkills);
  //DISPLAY EXIT BUTTON
  document
    .querySelector("#exit")
    .setAttribute("style", "display: inline-block");
  const pie = document.createElement("div");
  const pie1 = document.createElement("div");
  const pie2 = document.createElement("div");
  const pie3 = document.createElement("div");
  const rightDiv = document.createElement("div");
  const rightDiv1 = document.createElement("div");
  const rightDiv2 = document.createElement("div");
  const rightDiv3 = document.createElement("div");
  const leftDiv = document.createElement("div");
  const leftDiv1 = document.createElement("div");
  const leftDiv2 = document.createElement("div");
  const leftDiv3 = document.createElement("div");
  const percentDiv = document.createElement("div");
  const percentDiv1 = document.createElement("div");
  const percentDiv2 = document.createElement("div");
  const percentDiv3 = document.createElement("div");
  const numberDiv = document.createElement("div");
  const numberDiv1 = document.createElement("div");
  const numberDiv2 = document.createElement("div");
  const numberDiv3 = document.createElement("div");
  const nameDiv = document.createElement("div");
  const nameDiv1 = document.createElement("div");
  const nameDiv2 = document.createElement("div");
  const nameDiv3 = document.createElement("div");
  // ADD CLASSLIST
  pie.classList.add("pie1");
  rightDiv.classList.add("slice-right1");
  leftDiv.classList.add("slice-left1");
  percentDiv.classList.add("percent1");
  numberDiv.classList.add("number1");
  nameDiv.classList.add("name1");
  pie1.classList.add("pie1");
  rightDiv1.classList.add("slice-right1");
  leftDiv1.classList.add("slice-left1");
  percentDiv1.classList.add("percent1");
  numberDiv1.classList.add("number1");
  nameDiv1.classList.add("name1");
  pie2.classList.add("pie1");
  rightDiv2.classList.add("slice-right1");
  leftDiv2.classList.add("slice-left1");
  percentDiv2.classList.add("percent1");
  numberDiv2.classList.add("number1");
  nameDiv2.classList.add("name1");
  pie3.classList.add("pie1");
  rightDiv3.classList.add("slice-right1");
  leftDiv3.classList.add("slice-left1");
  percentDiv3.classList.add("percent1");
  numberDiv3.classList.add("number1");
  nameDiv3.classList.add("name1");
  //ADD INNERTEXT
  nameDiv.innerHTML = "HTML";
  numberDiv.innerHTML = "%99";
  nameDiv1.innerHTML = "CSS";
  numberDiv1.innerHTML = "%99";
  nameDiv2.innerHTML = "BOOTSTRAP";
  numberDiv2.innerHTML = "%80";
  nameDiv3.innerHTML = "JAVASCRIPT";
  numberDiv3.innerHTML = "%75";
  //APPEND0
  pie.appendChild(rightDiv);
  pie.appendChild(leftDiv);
  pie.appendChild(percentDiv);
  percentDiv.appendChild(numberDiv);
  percentDiv.appendChild(nameDiv);
  callAllPie.appendChild(pie);
  //APPEND1
  pie1.appendChild(rightDiv1);
  pie1.appendChild(leftDiv1);
  pie1.appendChild(percentDiv1);
  percentDiv1.appendChild(numberDiv1);
  percentDiv1.appendChild(nameDiv1);
  callAllPie.appendChild(pie1);
  //APPEND2
  pie2.appendChild(rightDiv2);
  pie2.appendChild(leftDiv2);
  pie2.appendChild(percentDiv2);
  percentDiv2.appendChild(numberDiv2);
  percentDiv2.appendChild(nameDiv2);
  callAllPie.appendChild(pie2);
  //APPEND3
  pie3.appendChild(rightDiv3);
  pie3.appendChild(leftDiv3);
  pie3.appendChild(percentDiv3);
  percentDiv3.appendChild(numberDiv3);
  percentDiv3.appendChild(nameDiv3);
  callAllPie.appendChild(pie3);
}

就像其他人已经说过的,你可以创建一个模板,并根据需要显示/隐藏。
然而,如果你需要使用javascript来生成它们,那么你可以通过创建一个函数来完成你在这里所做的所有重复的事情来减少行数。

function createDiv(className, innerHTML, parentDiv)
    {
        const div = document.createElement("div");
        div.classList.add(className);

        if (innerHTML)
        {
            div.innerHTML = innerHTML;
        }

        if (parentDiv)
        {
            parentDiv.appendChild(div);
        }

        return div;
    }

那就简单地叫它:

const nameDiv4 = createDiv("name1", "HTML", percentDiv);

这相当于:

const nameDiv = document.createElement("div");
nameDiv.classList.add("name1");
nameDiv.innerHTML = "HTML";
percentDiv.appendChild(nameDiv);
