      </el-form>
    </div>
  </div>

js代码

  export default {
    data () {
       /*证件号选择验证*/
      let valCarSel = (rule, value, callback) => {
        if (value === '') {
          callback(new Error('请选择证件'));
        }
      };
      /*证件号验证*/
      let validateCard = (rule, value, callback) => {
        let cardRule = value.replace(/[0-9a-zA-Z]{6,16}/g,'');
        if (value === '') {
          callback(new Error('请输入证件号'));
        } else {
          if (cardRule) {
            callback(new Error('证件号为长度在 6 到 16 位的英文字母和数字'));
          }
          callback();
        }
      };
      return {
           registerForm: {
              certificateType: '0',  
              certificateNumber: '111111',  

           },
           registerRules: {
             certificateType: [
            { required:true, validator: valCarSel, trigger: 'change' }
          ],
          certificateNumber: [
            { required:true, validator: validateCard, trigger: 'blur' }
          ],
          }
     }

subRegForm () {
        this.$refs.registerForm.validate((valid) => {
          if (valid) {
            this.$message({
              message: '注册成功',
              type: 'success'
            });
          } else {
            this.$message({
              message: '注册失败',
              type: 'error'
            });
            return false;
          }
        });
      }

并且有radio的时候还没有报错,radio到底哪里错了啊?

Answer 1

上面的验证函数改一下，多加一个else{callback()}，就可以了

let valCarSel = (rule, value, callback) => {
        if (value === '') {
          callback(new Error('请选择证件'));
        }else{
          callback();
        }
      };

Answer 2

certificateType 根本用不着校验吧
如果要校验，是不是也必须调用 callback()？
