JS 用巧妙的方式实现复制内容到剪贴板 ​

export function copyToClipboard(text) {
  let textArea = document.createElement("textarea");
  textArea.style.position = "fixed";
  textArea.style.top = "0";
  textArea.style.left = "0";
  textArea.style.width = "0";
  textArea.style.height = "0";
  textArea.style.padding = "0";
  textArea.style.border = "none";
  textArea.style.outline = "none";
  textArea.style.boxShadow = "none";
  textArea.style.background = "transparent";
  textArea.value = text;
  document.body.appendChild(textArea);
  textArea.select();

  try {
    let successful = document.execCommand("copy");
    let msg = successful ? "成功复制到剪贴板" : "该浏览器不支持点击复制到剪贴板";
    alert(msg);
  } catch (err) {
    alert("该浏览器不支持点击复制到剪贴板");
  }

  document.body.removeChild(textArea);
}
