有什么方法可以复制 div 的渲染 HTML？

Question

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。

我尝试了几个变体，包括 w3schools 的一个，但没有成功，其中一些只复制文本，但没有样式。

Answer 1

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 -->
        <table style="width: 525px; font-size: 11pt; font-family: Arial, sans-serif;" cellpadding="0" cellspacing="0" fgid="15712">

Answer 2

document.execCommand() 已弃用。

使用剪贴板API，您可以以非常简单的方式完成相同的操作：

try {
  const htmlCode = document.getElementById("html").innerHTML
  const blobInput = new Blob([htmlCode], { type: 'text/html' })
  navigator.clipboard.write([new ClipboardItem({ 'text/html': blobInput })])
  alert('Copied')
} catch (e) {
  alert(e)
}
