Prismjs没有突出显示动态内容

Question

我使用Prismjs进行语法高亮显示，方法是使用fetch方法从json文件中获取数据，并使用js动态地呈现html。问题是Prismjs是在本地环境中完成它的工作，而不是在生产中，顺便说一下，我正在使用Netlify来托管这个站点。我还在使用Prismjs.highlightall()方法，但在托管站点之后，它似乎无法工作。链接到网站：css-简称

JavaScript代码：

const root = document.getElementById("root");

fetch("./shorthands.json")
  .then((res) => res.json())
  .then((data) => appendData(data))
  .catch((err) => console.log(err));

function appendData(data) {
  for (let i = 0; i < data.length; i++) {
    const syntaxContainer = document.createElement("div");
    syntaxContainer.classList.add("w-full", "py-5");

    syntaxContainer.innerHTML = `<div class="flex items-center" id="${data[i].id}">
          <img src="./hashtag.svg" alt="hashlink" class="w-8" />
          <h1 class="text-white text-3xl">${data[i].name}</h1>
        </div>
        <div class="mt-5 ml-2 text-white">
          <p class="text-lg">longhand</p>
          <pre id="pre" >
          <code class="language-css">${data[i].longhand}
              </code></pre>
        </div>
        <div class="mt-5 ml-2 text-white">
          <p class="text-lg">shorthand</p>
          <pre><code class="language-css ">${data[i].shorthand}
              </code></pre>
        </div>

        </div>
        `;

    root.appendChild(syntaxContainer);
  }
}

我想要呈现的一些python代码也有类似的问题。首先通过将字符串传递给Prism.highlight()来解决这个问题。所以如果输入字符串是input_str

html_with_highlight = Prism.highlight(input_str, Prism.languages.html, 'html'); syntaxContainer.innerHTML = html_with_highlight;

您可以找到函数文档这里。

希望这能帮上忙！
