Props Match Params Id 无法读取且 Props.id 未定义

Question

If I am using const currentUserId = props.id then the error will be props.match is undefined , and the variable "userId" even is undefined when i am trying to console log.

Then, I using props.match.params.id the code can't even being read, it's only blank

Im also trying to modify the code become const currentUserId = props.computedMatch.params.id; but nothing works

My code:

import React, {useContext, useState, useEffect} from 'react';
import { GlobalContext } from '../context/GlobalState';
import { Link, useNavigate } from 'react-router-dom';
import { v4 as uuid } from 'uuid';
import {
  Form,
  FormGroup,
  Label,
  Input,
  Button
} from 'reactstrap';

export const EditUser = (props) => {
  const [selectedUser, setSelectedUser] = useState({
    id: '',
    name: ''
  });
  const { users, editUser } = useContext(GlobalContext);
  const history = useNavigate();
  const currentUserId = props.match.params.id;

  useEffect(() => {
    const userId = currentUserId;
    console.log(typeof userId);
    const selectedUser = users.find(user => user.id === Number(userId))
    setSelectedUser(selectedUser)
    console.log(selectedUser);
  }, [currentUserId, users])

  const onSubmit = () => {
  
    history('/');
  }

  const onChange = (e) => {

  }
  return (
    <Form onSubmit={onSubmit}>
      <FormGroup>
        <Label>Nama</Label>
        <Input type='text' onChange={onChange} placeholder='Ganti Nama Disini!'></Input>
      </FormGroup>
      <Button type='submit'>Edit Data</Button>
      <Link to="/" className="btn btn-danger ml-2" style={{ marginLeft: "10px"}}>Cancel</Link>
    </Form>
  )
}

use withRouter

 import React, {useContext, useState, useEffect} from 'react'; import { GlobalContext } from '../context/GlobalState'; import { Link, useNavigate } from 'react-router-dom'; import { withRouter } from 'react-router'; // here added import { v4 as uuid } from 'uuid'; import { Form, FormGroup, Label, Input, Button } from 'reactstrap'; const EditUser = (props) => { // here changed const [selectedUser, setSelectedUser] = useState({ id: '', name: '' }); const { users, editUser } = useContext(GlobalContext); const history = useNavigate(); const currentUserId = this.props.match.params.id; useEffect(() => { const userId = currentUserId; console.log(typeof userId); const selectedUser = users.find(user => user.id === Number(userId)) setSelectedUser(selectedUser) console.log(selectedUser); }, [currentUserId, users]) const onSubmit = () => { history('/'); } const onChange = (e) => { } return ( <Form onSubmit={onSubmit}> <FormGroup> <Label>Nama</Label> <Input type='text' onChange={onChange} placeholder='Ganti Nama Disini!'></Input> </FormGroup> <Button type='submit'>Edit Data</Button> <Link to="/" className="btn btn-danger ml-2" style={{ marginLeft: "10px"}}>Cancel</Link> </Form> ) } export default withRouter(EditUser); // here added

i hope this will fix

import { useParams } from 'react-router-dom';
const { id: currentUserId } = useParams();
