复制按钮调用copyMes，handleText处理复制出去的信息格式

//处理待复制文本
  handleText = (item) => {
    let bankOfDeposit = "",
      bankAccount = "",
      companyAddress = "",
      companyTelephone = "",
      taxNumber = "",
      titleName = "";
    if (item) {
      titleName = item?.titleName;
      taxNumber = item?.taxNumber;
      companyAddress = item?.companyAddress;
      companyTelephone = item?.companyTelephone;
      bankOfDeposit = item?.bankOfDeposit;
      bankAccount = item?.bankAccount;
    }

    let results =
      "名称：" +
      titleName +
      `\n` +
      "纳税人识别号：" +
      taxNumber +
      `\n` +
      "地址：" +
      companyAddress +

      bankAccount;

    return results;
  };
