vue中把字符串复制到剪切板

copyText(text) {
  var textarea = document.createElement("input");//创建input对象
  var currentFocus = document.activeElement;//当前获得焦点的元素
  document.body.appendChild(textarea);//添加元素
  textarea.value = text;
  textarea.focus();
  if(textarea.setSelectionRange)
      textarea.setSelectionRange(0, textarea.value.length);//获取光标起始位置到结束位置
  else
      textarea.select();
  try {
      var flag = document.execCommand("copy");//执行复制
  } catch(eo) {
      var flag = false;
  }
  document.body.removeChild(textarea);//删除元素
  currentFocus.focus();
  return flag;
},
// 点击复制
handleCopyClick(address, officialAccountId){
  let str1 = 'https://personal.tohours.com/dgt/admin/agentCenter/home/env-html'
  let str2 = '/#/home?channelid=' + officialAccountId + '&address=' + address
  let str = str1 + str2
  let flag = this.copyText(str); //传递文本，项目需要拼接str1和str2，复制的是str
  alert(flag ? "复制成功！" : "复制失败！");
}
