Mic*_*rds 9 javascript reactjs yup formik
我的 React 应用程序中有以下 Yup 配置:
 const schema = yup.object().shape({
        email: yup.string()
            .email('E-mail is not valid!')
            .required('E-mail is required!'),
        password: yup.string()
            .min(6, 'Password has to be longer than 6 characters!')
            .required('Password is required!'),
        tandc: yup.boolean()
            .oneOf([true], "You must accept the terms and conditions")
    })
我的表单如下所示(使用 Formik):
 <Form>
                    <div className="form-group">
                        <label >Email
                        <Field type="email" name="email" className="form-control" />
                        </label>
                        <ErrorMessage name="email" component="div" className="invalid-feedback" />
                    </div>
                    <div className="form-group">
                        <label >Password
                        <Field type="password" name="password" className="form-control"  />
                        </label>
                        <ErrorMessage name="password" component="div" className="invalid-feedback" />
                    </div>
                    <div className="form-group">
                        <Field type="checkbox" name="tandc" className="form-check-input"  id="tandc" />
                        <ErrorMessage name="tandc" component="div" className="invalid-feedback" />
                        <label htmlFor="tandc" >I agree to the Terms and Conditions
                        </label>
                    </div>
                    <PrimaryButton label="Login" disabled={isSubmitting} type="submit">
                        Submit
                    </PrimaryButton>
                </Form>
如果用户单击表单上的提交,Yup 会验证电子邮件和密码字段,但忽略复选框字段:
只有先选中然后取消选中条款和条件,我才能使复选框验证生效。
如何让它工作,以便在用户单击提交按钮时显示错误消息?

为了
yup.boolean().oneOf([true],'Message');
要工作,您必须将该字段的初始值设置为true或false。
在你的情况下,它看起来像这样
tandc : false
无论您在何处设置初始值
如果您使用的是react-hook-form:
 const schema = yup.object().shape({
        ...
    tandc: yup.bool() // use bool instead of boolean
        .oneOf([true], "You must accept the terms and conditions")
 })
