编辑b2/Assets/fontend/single.js，在最上方插入以下代码。
function copyToClipboard(content) {
if (window.clipboardData) {
window.clipboardData.setData('text', content);
} else {
(function (content) {
document.oncopy = function (e) {
e.clipboardData.setData('text', content);
e.preventDefault();
document.oncopy = null;
}
})(content);
document.execCommand('Copy');
}
}
编辑b2/Assets/fontend/single.js，搜索prettyPrint()，在下方插入以下代码。
[...document.getElementsByTagName('pre')].forEach(item => {
item.style.position = "relative";
if (!item.querySelector('.sticky-button')) {
let copyButton = document.createElement("button")
copyButton.className = 'sticky-button'; // 使用 sticky-button 類別
copyButton.innerHTML = "一键复制";
copyButton.onclick = function () {
let copyData = item.lastChild.innerText;
navigator.clipboard.writeText(copyData).then(() => {
copyButton.innerHTML = "复制成功";
setTimeout(function () {
copyButton.innerHTML = "一键复制";
}, 1000);
});
}
// 將按鈕添加到 pre 內部，並且在 ol 上面
item.insertBefore(copyButton, item.firstChild);
}
});
CSS加入代码（限定最大高数、带滚动条、代码超出自动换行）
