I'm trying to redirect the user after a submit button has been pressed in my react app, but redirect never happens. After submit button I'm sending data via axios to an API, then I want to redirect. This is done by having first set the state for redirect to false in my constructor, after having sent the axios call I'm trying to set it's state to true then conditionally render a react router redirect if the value is true.

I have confirmed that Axios actually sends data to the back end. But no idea why the conditional render does not run after the value is set to true. Any ideas? :)

My code:

import React from 'react';
import Button from '@material-ui/core/Button';
import CssBaseline from '@material-ui/core/CssBaseline';
import axios from 'axios';
import { Redirect } from 'react-router';

class confirmWithdraw extends React.Component {
  constructor() {
    super();
    this.state = {
      redirect: false
    };

    this.handleSubmit = this.handleSubmit.bind(this);
  }

  handleEvent = e => {
    this.setState({ [e.target.name]: e.target.value });
  };

  handleSubmit = e => {
    e.preventDefault();
    const amount = sessionStorage.getItem('amount');
    const serverCardNumber = sessionStorage.getItem('cardnumber');
    axios({
      method: 'post',
      url: '/api/whidrawal',
      data: {
        amount,
        serverCardNumber
      }
    }).then(() => this.setState({ redirect: true }));
  };

  render() {
    const { redirect } = this.state;
    if (redirect) {
      return <Redirect to="/moneyform" />;
    }
    return (
      <React.Fragment>
        {redirect ? <Redirect to="/moneyform" /> : null}
        <div>
          Select action -> Withdraw -> <b>Confirm -></b> Take cash -> Finished? -> Take card{' '}
        </div>
        <div>{sessionStorage.getItem('amount')}</div>
        <h1>Please confirm the withdraw of {sessionStorage.getItem('amount')} NOK </h1>
        <CssBaseline /> {/* */}
        <form onSubmit={this.handleSubmit}>
          <br />
          {/* Bytt ut med CSS block elementer eller noe slikt, bytt name på form fields til å hentes via JS  */}
          <div className="container">
            <Button type="submit" variant="contained" color="primary" className="floatRight">
              Confirm
            </Button>
            <Button type="submit" variant="contained" color="secondary" className="floatLeft">
              Cancel
            </Button>
          </div>
        </form>
      </React.Fragment>
    );
  }
}

• 1 Can you confirm that the ponent does re-render after you submit? – DSCH Commented Nov 6, 2018 at 11:18
• does backend respond with status 200? – simka Commented Nov 6, 2018 at 11:19
• export the ponent by connecting it with withRouter HOC, export default withRouter(confirmWithdraw); Also as a convention your React ponents name must begin with uppercase characters – Shubham Khatri Commented Nov 6, 2018 at 11:27
• are you sure that .then(() => this.setState({ redirect: true })); is actually executed? The answer to this post might solve your problem, but your original approach was ok, there must be something else not working. – c-chavez Commented Nov 6, 2018 at 16:27

By assuming you are using react-router v4, you will want to use history object to navigate.

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

handleSubmit = () => {
  ...
  this.props.history.push('/moneyform');
}

render() {
  return (
    <ReactFragment>
      <div>
      ...
    </ReactFragment>
  )
}


export default withRouter(confirmWithdraw);
