如何使用React将注册页面重定向到另一个页面& Formik

Question

页面在点击“注册”按钮后没有响应，我想知道代码出了什么问题。我希望它重定向到“仪表板/电子学习”页面。NavLink不指向“注册”按钮，如果我在“注册”按钮周围添加一个NavLink，则验证将毫无意义。

下面是register.js文件。

​

import React from 'react';
import { NavLink } from 'react-router-dom';
import { Button, Form } from 'react-bootstrap';
import * as Yup from 'yup';
import { useFormik } from 'formik';
import LayoutFullpage from 'layout/LayoutFullpage';
import CsLineIcons from 'cs-line-icons/CsLineIcons';
import HtmlHead from 'components/html-head/HtmlHead';

const Register = () => {
  const title = 'Register';
  const description = 'Register Page';

  const validationSchema = Yup.object().shape({
    name: Yup.string().required('Name is required'),
    email: Yup.string().email().required('Email is required'),
    password: Yup.string().min(6, 'Must be at least 6 chars!').required('Password is required'),
    terms: Yup.bool().required().oneOf([true], 'Terms must be accepted'),
  });
  const initialValues = { name: '', email: '', password: '', terms: false };
  const onSubmit = (values) => console.log('submit form', values);

  const formik = useFormik({ initialValues, validationSchema, onSubmit });
  const { handleSubmit, handleChange, values, touched, errors } = formik;

  const leftSide = (
    <div className="min-h-100 d-flex align-items-center">

您可以使用来自useNavigate的react-router-dom钩子

请在下面找到必要的片段。

import { useNavigate } from 'react-router-dom';

...

const navigate = useNavigate();
const onSubmit = (values) => {
  console.log('submit form', values);
  navigate('dashboards/elearning');
};

...
