创建一个promise对象

导语

歌谣 歌谣 有什么好的方式在react中将数据传给父组件

代码部分

``` return new Promise((resolve, reject) => { this.props.form.validateFieldsAndScroll((error, values) => { if (error) { reject(); return; }
const { activeUpdateData = {}, type } = this.props;
    const { birthdayTime } = values;
    const { imgUrl, listCards, activeOrgan, tags, tagList,

tagListInfo } = this.state;
if (!imgUrl && !activeUpdateData.headImg) {
      message.info(`请上传讲师头像！`);
      reject();
      return;
    }
    console.log(values, 'values');
    var arr2 = [];
    console.log(tagList, 'tagListTest');
    tagList.map((item) => {
      if (item.checked == true) {
        arr2.push({
          tagCode: item.tagCode,
          weight: item.weight ||

(tagListInfo && tagListInfo[0] .weight), tagGroupCode: item.tagGroupCode || (tagListInfo && tagListInfo[0].tagGroupCode), tagBizType: item.tagBizType || (tagListInfo && tagListInfo[0].tagBizType), }); } return arr2; }); if (arr2.length == 0) { this.setState({ errType: 'error', errMsg: '请选择主营课程', }); return false; } const payload = { ...values, lecturerOrganizationCode: values.lecturerOrganizationCode[0]. code, invitePeople: values.invitePeople[0].customerCode, applyCustomerCode: values.applyCustomerCode[0].customerCode, lecturerId: activeUpdateData.lecturerId, certificateId: activeUpdateData.certificateId, contactId: activeUpdateData.contactId, birthdayTime: birthdayTime && birthdayTime.valueOf(), headImg: imgUrl || activeUpdateData.headImg, businessMerchantCode: values.lecturerOrganizationCode[0].businessMerchantCode || activeUpdateData.businessMerchantCode, // activeOrgan.businessMerchantCode || activeUpdateData.businessMerchantCode, //经营商户编号 platformMerchantCode: values.lecturerOrganizationCode[0].platformMerchantCode || activeUpdateData.businessMerchantCode, // activeOrgan.platformMerchantCode || activeUpdateData.businessMerchantCode, //平台商户编号 // lecturerOrganizationCode: activeOrgan.code || activeUpdateData.lecturerOrganizationCode,

certificateList: listCards.map((item) => {
        return {
          certificateImgPath: item.imageUrl,
          certificateImgType: item.key,
        };
      }),
      // tagList &&
      tagBizList: arr2,
      // lecturerDetails: text,
    };
    if (type === 'update') {
      payload.lecturerDetails = activeUpdateData.lecturerDetails;
      payload.lecturerId = activeUpdateData.lecturerId;
      payload.organizationId = activeUpdateData.organizationId;
    }
    console.log(payload, 'payload');
    resolve(payload);
  });
});
}; ```

总结

利用promise的正确返回值作为结果返回给父组件使用
