有什么方法可以复制 div 的呈现 HTML？答案

【问题描述】：

我正在开发电子邮件签名生成器，我想通过按下按钮来复制最终签名，而不是手动选择签名并将其复制到剪贴板。这意味着我需要它们的图像、文本和样式。

我尝试了几种变体，包括 w3schools 的一种，但没有成功，其中一些只是复制文本，但没有样式。

示例：https://www.mail-signatures.com/signature-generator/

【问题讨论】：

所有样式都必须是内联的。您确实想导出 HTML，对吗？
不，这就是问题所在。例如 Gmail（但其他人也）使用呈现的 html 格式，而不是 html 代码，这就是我需要复制和粘贴它的原因。
出于完全相同的目的，我有同样的问题。我也叫亚历克斯。怎么回事？
这个按钮在哪里？您的意思是您正在构建自己的签名生成器，还是使用示例并且您想要例如获取 HTML 的浏览器扩展？

请尝试以下代码。

function copyToClipboard(html) {
    var container = document.createElement('div')
    container.innerHTML = html
    container.style.position = 'fixed'
    container.style.pointerEvents = 'none'
    container.style.opacity = 0
    document.body.appendChild(container)
    window.getSelection().removeAllRanges()
    var range = document.createRange()
    range.selectNode(container)
    window.getSelection().addRange(range)
    document.execCommand('copy')
    document.body.removeChild(container);
    alert("Copied")
}

document.querySelector('button').onclick = function () {
    var htmlEditor = document.getElementById("html");
    copyToClipboard(htmlEditor.innerHTML)
}

<button>Copy</button>
    <div id="html">
        <!-- The HTML you want to copy -->
