javascript - 单击重定向页面上的 react 按钮

Question

我正在使用 React 和 bootstrap 开发一个 Web 应用程序。当谈到应用按钮 onClick 时，我很难将页面重定向到另一个页面。如果在 href 之后，我无法转到另一个页面。

那么您能告诉我是否需要使用react-navigation或其他方法来使用Button onClick来导航页面？

import React, { Component } from 'react';
import { Button, Card, CardBody, CardGroup, Col, Container, Input, InputGroup, InputGroupAddon, InputGroupText, Row, NavLink  } from 'reactstrap';
 
class LoginLayout extends Component {
 
  render() {
    return (
 <div className="app flex-row align-items-center">
        <Container>
     ...
                    <Row>
                      <Col xs="6">                      
                        <Button color="primary" className="px-4">
                            Login
                         </Button>
                      </Col>
                      <Col xs="6" className="text-right">
                        <Button color="link" className="px-0">Forgot password?</Button>
                      </Col>
                    </Row>
               ...
        </Container>
      </div>
    );
  }
}

更新:

React Router v6:

import React from 'react';
import { useNavigate } from "react-router-dom";
function LoginLayout() {
  
  let navigate = useNavigate(); 
  const routeChange = () =>{ 
    let path = `newPath`; 
    navigate(path);
  }
  
  return (
     <div className="app flex-row align-items-center">
      <Container>
      ...          
          <Button color="primary" className="px-4"
            onClick={routeChange}
              >
              Login
            </Button>
      ...
       </Container>
    </div>
  );
}}

带钩子(Hook)的 React Router v5:

import React from 'react';
import { useHistory } from "react-router-dom";
function LoginLayout() {
  
  const history = useHistory();
  
  const routeChange = () =>{ 
    let path = `newPath`; 
    history.push(path);
  }

  return (
      <div className="app flex-row align-items-center">
        <Container>
          ...
          <Row>
            <Col xs="6">                      
              <Button color="primary" className="px-4"
                onClick={routeChange}
                  >
                  Login
                </Button>
            </Col>
            <Col xs="6" className="text-right">
              <Button color="link" className="px-0">Forgot password?</Button>
            </Col>
          </Row>
          ...
        </Container>
      </div>
  );
}
export default LoginLayout;

使用 React Router v5:

import { useHistory } from 'react-router-dom';
import { Button, Card, CardBody, CardGroup, Col, Container, Input, InputGroup, InputGroupAddon, InputGroupText, Row, NavLink  } from 'reactstrap';
    
class LoginLayout extends Component {
  
  routeChange=()=> {
    let path = `newPath`;
    let history = useHistory();
    history.push(path);
  }

  render() {
    return (
      <div className="app flex-row align-items-center">
        <Container>
          ...
          <Row>
            <Col xs="6">                      
              <Button color="primary" className="px-4"
                onClick={this.routeChange}
                  >
                  Login
                </Button>
            </Col>
            <Col xs="6" className="text-right">
              <Button color="link" className="px-0">Forgot password?</Button>
            </Col>
          </Row>
          ...
        </Container>
      </div>
    );
  }
}

export default LoginLayout;

使用 React Router v4:

import { withRouter } from 'react-router-dom';
import { Button, Card, CardBody, CardGroup, Col, Container, Input, InputGroup, InputGroupAddon, InputGroupText, Row, NavLink  } from 'reactstrap';
    
class LoginLayout extends Component {
  constuctor() {
    this.routeChange = this.routeChange.bind(this);
  }

  routeChange() {
    let path = `newPath`;
    this.props.history.push(path);
  }

  render() {
    return (
      <div className="app flex-row align-items-center">
        <Container>
          ...
          <Row>
            <Col xs="6">                      
              <Button color="primary" className="px-4"
                onClick={this.routeChange}
                  >
                  Login
                </Button>
            </Col>
            <Col xs="6" className="text-right">
              <Button color="link" className="px-0">Forgot password?</Button>
            </Col>
          </Row>
          ...
        </Container>
      </div>
    );
  }
}

export default withRouter(LoginLayout);
