我想复制 Ghost 使用 prismjs 设计的精确代码块设计.

这是链接 - https://ghost.org/tutorials/code-snippets-in-ghost/

最终结果必须类似于下面的屏幕截图。

enter image description here

我试过的是这样的。

enter image description here

我在 prismjs 中为代码块格式化启用的设置链接。

https://prismjs.com/download.html#themes=prism-okaidia&languages=css+clike+javascript+css-extras&plugins=autolinker+custom-class+show-language+inline-color+autoloader+toolbar+copy-to-clipboard+match-braces

最佳答案

解决方案 1:

如果你想要和页面上的样式一模一样

https://ghost.org/tutorials/code-snippets-in-ghost/

这是获取他们的主题文件的说明,下载并命名为 prism.css

  1. DevTools 中打开“Sources”选项卡
  2. 找到并点击/tutorials/assets/built/components/syntax-highlighting.css文件
  3. 右键单击内容为 syntax-highlighting.css
  4. 的选项卡
  5. 另存为... prism.css

包含复制按钮在内的所有规则的代码段:

(当使用来自 CDN 的 prism.js 时,该按钮未显示在片段中)

相似度是通过添加css规则实现的,但是没有动画。 enter image description here

解决方案 2:

代码中最有趣的部分来自研究 ghost.org 上的源代码(按钮事件:/tutorials/src/js/post/code-copy.js) 和 github 上按钮的来源, 但是,为了让它工作,我不得不将两个脚本共生因为它不能正常工作(来自 github 的函数 copyTextToClipboardfallbackCopyTextToClipboard 已转换为异步)。

现在复制按钮的外观和功能与原始按钮一样:

enter image description here

function initCodeCopy() {
const codeBlocks = document.querySelectorAll('code[class*="language-"]');
codeBlocks.forEach((block) => {
const lang = parseLanguage(block);
const referenceEl = block.parentElement;
const parent = block.parentElement.parentElement;

const wrapper = document.createElement('div');
wrapper.className = 'code-wrapper';
parent.insertBefore(wrapper, referenceEl);
wrapper.append(block.parentElement);

const copyBtn = document.createElement('button');
copyBtn.setAttribute('class', 'copy-button');
copyBtn.setAttribute('data-lang', lang);
copyBtn.innerHTML = `${lang} <svg viewBox="0 0 24 24"><path fill="none" d="M0 0h24v24H0z"/><path d="M7 6V3a1 1 0 0 1 1-1h12a1 1 0 0 1 1 1v14a1 1 0 0 1-1 1h-3v3c0 .552-.45 1-1.007 1H4.007A1.001 1.001 0 0 1 3 21l.003-14c0-.552.45-1 1.007-1H7zM5.003 8L5 20h10V8H5.003zM9 6h8v10h2V4H9v2z" fill="currentColor"/></svg>`;

wrapper.insertAdjacentElement('beforeend', copyBtn);
});

function parseLanguage(block) {
const className = block.className;
if (className.startsWith('language')) {
const [prefix, lang] = className.split('-');
return lang;
}
}

async function fallbackCopyTextToClipboard(text) {
return new Promise((resolve, reject) => {
var textArea = document.createElement('textarea');
textArea.value = copyInfo.getText();
// Avoid scrolling to bottom
textArea.style.top = '0';
textArea.style.left = '0';
textArea.style.position = 'fixed';
document.body.appendChild(textArea);
textArea.focus();
textArea.select();
try {
var successful = document.execCommand('copy');
setTimeout(function () {
if (successful) {
resolve('success')
} else {
reject('error')
}
}, 1);
} catch (err) {
setTimeout(function () {
reject(err)
}, 1);
} finally {
document.body.removeChild(textArea);
}
})
}

async function copyTextToClipboard(text) {
return new Promise((resolve, reject) => {
if (navigator.clipboard) {
navigator.clipboard.writeText(text).then(
resolve(), function () {
// try the fallback in case `writeText` didn't work
fallbackCopyTextToClipboard(text).then(
() => resolve(),
() => reject()
)
});
} else {
fallbackCopyTextToClipboard(text).then(
() => resolve(),
() => reject()
)
}
})
}

function copy(e) {
const btn = e.currentTarget;
const lang = btn.dataset.lang;
const text = e.currentTarget.previousSibling.children[0].textContent;
copyTextToClipboard(text)
.then(
() => {
btn.innerHTML = `copied! <svg viewBox="0 0 24 24"><path fill="none" d="M0 0h24v24H0z"/><path d="M7 6V3a1 1 0 0 1 1-1h12a1 1 0 0 1 1 1v14a1 1 0 0 1-1 1h-3v3c0 .552-.45 1-1.007 1H4.007A1.001 1.001 0 0 1 3 21l.003-14c0-.552.45-1 1.007-1H7zm2 0h8v10h2V4H9v2z" fill="currentColor"/></svg>`;
btn.setAttribute('style', 'opacity: 1');

},
() => alert('failed to copy'),
);

setTimeout(() => {
btn.removeAttribute('style');
btn.innerHTML = `${lang} <svg viewBox="0 0 24 24"><path fill="none" d="M0 0h24v24H0z"/><path d="M7 6V3a1 1 0 0 1 1-1h12a1 1 0 0 1 1 1v14a1 1 0 0 1-1 1h-3v3c0 .552-.45 1-1.007 1H4.007A1.001 1.001 0 0 1 3 21l.003-14c0-.552.45-1 1.007-1H7zM5.003 8L5 20h10V8H5.003zM9 6h8v10h2V4H9v2z" fill="currentColor"/></svg>`;
}, 3000);
}

const copyButtons = document.querySelectorAll('.copy-button');

copyButtons.forEach((btn) => {
btn.addEventListener('click', copy);
});
}
