js实现复制，兼容safari

const copyToClipboard = async (text) => {
  if (navigator.clipboard && navigator.permissions) {
    await navigator.clipboard.writeText(text)
  } else {
    const textareaEl = document.createElement('textarea')
    textareaEl.setAttribute('readonly', 'readonly') // 防止手机上弹出软键盘
    textareaEl.value = text
    document.body.appendChild(textareaEl)
    textareaEl.select()
    const res = document.execCommand('copy')
    document.body.removeChild(textareaEl)
  }
  console.log('复制成功')
}
