react button onClick redirect page

Question

I am working on web application using React and bootstrap. When it comes to applying button onClick, it takes me hard time to let my page being redirect to another. if after a href , I cannot go the another page.

So would you please tell me is there any need for using react-navigation or other to navigate the page using Button onClick ?

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>
    );
  }
}

Answer 1

A simple click handler on the button, and setting window.location.hash will do the trick, assuming that your destination is also within the app.

You can listen to the hashchange event on window, parse the URL you get, call this.setState(), and you have your own simple router, no library needed.

class LoginLayout extends Component {
    constuctor() {
      this.handlePageChange = this.handlePageChange.bind(this);
      this.handleRouteChange = this.handleRouteChange.bind(this);
      this.state = { page_number: 0 }
    }

  handlePageChange() {
    window.location.hash = "#/my/target/url";
  }

  handleRouteChange(event) {
    const destination = event.newURL;
    // check the URL string, or whatever other condition, to determine
    // how to set internal state.
    if (some_condition) {
      this.setState({ page_number: 1 });
    }
  }

  componentDidMount() {
    window.addEventListener('hashchange', this.handleRouteChange, false);
  }

  render() {
    // @TODO: check this.state.page_number and render the correct page.
    return (
      <div className="app flex-row align-items-center">
        <Container>
          ...
                <Row>
                  <Col xs="6">                      
                    <Button 
                       color="primary"
                       className="px-4"
                       onClick={this.handlePageChange}
                    >
                        Login
                     </Button>
                  </Col>
                  <Col xs="6" className="text-right">
                    <Button color="link" className="px-0">Forgot password </Button>
                  </Col>
                </Row>
           ...
        </Container>
      </div>
    );
  }
}

I was also having the trouble to route to a different view using navlink.

My implementation was as follows and works perfectly;

<NavLink tag='li'>
  <div
    onClick={() =>
      this.props.history.push('/admin/my- settings')
    }
  >
    <DropdownItem className='nav-item'>
      Settings
    </DropdownItem>
  </div>
</NavLink>

Wrap it with a div, assign the onClick handler to the div. Use the history object to push a new view.

Answer 3

First, import it:

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

Then, in function or class:

const history = useHistory();

Finally, you put it in the onClick function:

<Button onClick={()=> history.push("/mypage")}>Click me!</Button>

Answer 4

A very simple way to do this is by the following:

onClick={this.fun.bind(this)}

and for the function:

fun() {
  this.props.history.push("/Home");
}

finlay you need to import withRouter:

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

and export it as:

export default withRouter (comp_name);

Answer 5

useHistory() from react-router-dom can fix your problem

import React from 'react';
import { useHistory } from "react-router-dom";
function NavigationDemo() {
  const history = useHistory();
  const navigateTo = () => history.push('/componentURL');//eg.history.push('/login');

  return (
   <div>
   <button onClick={navigateTo} type="button" />
   </div>
  );
}
export default NavigationDemo;

With React Router v5.1:

import {useHistory} from 'react-router-dom';
import React, {Component} from 'react';
import {Button} from 'reactstrap';
.....
.....
export class yourComponent extends Component {
    .....
    componentDidMount() { 
        let history = useHistory;
        .......
    }

    render() {
        return(
        .....
        .....
            <Button className="fooBarClass" onClick={() => history.back()}>Back</Button>

        )
    }
}
