Trying to figure out how can I go back to the previous page. I am using [react-router-v4][1]
This is the code I have configured in my first landing page:
<Router>
<div>
<Link to="/"><div className="routerStyle"><Glyphicon glyph="home" /></div></Link>
<Route exact path="/" component={Page1}/>
<Route path="/Page2" component={Page2}/>
<Route path="/Page3" component={Page3}/>
</div>
</Router>
In order to forward to subsequent pages, I simply do:
this.props.history.push('/Page2');
However, how can I go back to previous page?
Tried few things like mentioned below but no luck:
1. this.props.history.goBack();
Gives error:
TypeError: null is not an object (evaluating 'this.props')
this.context.router.goBack();Gives error:
TypeError: null is not an object (evaluating 'this.context')
this.props.history.push('/');Gives error:
TypeError: null is not an object (evaluating 'this.props')
Posting the Page1 code here below:
import React, {Component} from 'react';
import {Button} from 'react-bootstrap';
class Page1 extends Component {
constructor(props) {
super(props);
this.handleNext = this.handleNext.bind(this);
}
handleNext() {
this.props.history.push('/page2');
}
handleBack() {
this.props.history.push('/');
}
/*
* Main render method of this class
*/
render() {
return (
<div>
{/* some component code */}
<div className="navigationButtonsLeft">
<Button onClick={this.handleBack} bsStyle="success">< Back</Button>
</div>
<div className="navigationButtonsRight">
<Button onClick={this.handleNext} bsStyle="success">Next ></Button>
</div>
</div>
);
}
export default Page1;
I think the issue is with binding:
constructor(props){
super(props);
this.goBack = this.goBack.bind(this); // i think you are missing this
}
goBack(){
this.props.history.goBack();
}
.....
<button onClick={this.goBack}>Go Back</button>
As I have assumed before you posted the code:
constructor(props) {
super(props);
this.handleNext = this.handleNext.bind(this);
this.handleBack = this.handleBack.bind(this); // you are missing this line
}
UPDATED:
Now we have hook, so we can do it easily by using useHistory
const history = useHistory()
const goBack = () => {
history.goBack()
}
return (
<button type="button" onClick={goBack}>
Go back
</button>
);
ORIGINAL POST:
this.props.history.goBack();
This is the correct solution for react-router v4
But one thing you should keep in mind is that you need to make sure this.props.history is existed.
That means you need to call this function this.props.history.goBack(); inside the component that is wrapped by < Route/>
If you call this function in a component that deeper in the component tree, it will not work.
EDIT:
If you want to have history object in the component that is deeper in the component tree (which is not wrapped by < Route>), you can do something like this:
...
import {withRouter} from 'react-router-dom';
class Demo extends Component {
...
// Inside this you can use this.props.history.goBack();
}
export default withRouter(Demo);
For use with React Router v4 and a functional component anywhere in the dom-tree.
import React from 'react';
import { withRouter } from 'react-router-dom';
const GoBack = ({ history }) => <img src="./images/back.png" onClick={() => history.goBack()} alt="Go back" />;
export default withRouter(GoBack);
