按钮实现复制

前端实现复制有两种方法：

• 使用document.execCommand('Copy);
• 使用Selection对象

const handleCopyToken = (token) => {
  const textArea = document.createElement('textArea');
  textArea.value = token;
  document.body.appendChild(textArea);
  textArea.select();
  try {
    if (document.execCommand('Copy')) {
      Message.success(`${t('dataset.copySuccess')}`);
    } else {
      Message.error(`${t('dataset.copyFailed')}`);
    }
  } catch (err) {
    Message.error(`${t('dataset.copyFailed')}`);
  }
  document.body.removeChild(textArea);
};

const copyCellData = (row, column, cell) => {
  const item = cell.getElementsByClassName('cell')[0];
  const selection = window.getSelection();
  const range = document.createRange();
  range.selectNodeContents(item);
  selection.removeAllRanges();
  selection.addRange(range);
};
