香草 js 的微光效果

Question

这是我的代码，我正在尝试在其上实现微光加载效果。我制作了效果，您可以在初始渲染中看到它。问题是我不知道如何使用它。第一个文本内容来自我的 html 文件，不需要 ajax 调用。但是当单击按钮时，请求将发送到 api，只要来自 ajax 的数据调用 returns，效果就会显示。然后它应该再次消失。我完全糊涂了。

const btn = document.getElementById('jokeBtn');
const text = document.getElementById('text');

const loading = document.getElementById('shimmer');

const url = 'https://icanhazdadjoke.com/';

async function getter() {
  const initialPromise = await fetch(url, {
    headers: {
      Accept: 'application/json',
    },
  });
  const myPromise = await initialPromise.json();
  text.innerHTML = myPromise.joke;
  loading.style.display = 'none';
}

btn.addEventListener('click', getter);
