How to use react-router-redux routeActions?

问题

I'm trying to modify the example code of react-router-redux. https://github.com/rackt/react-router-redux/blob/master/examples/basic/components/Home.js

this is my Home.js

class Home extends Component {
    onSubmit(props) {
        this.props.routeActions.push('/foo');    
    }
}

I also have a mapDispatchToProps for it.

function mapDispatchToProps(dispatch){
    return bindActionCreators({ routeActions },dispatch);
}

When i called onSubmit function, I got an error

Uncaught TypeError: this.props.routeActions.push is not a function

If i remove this.props in onSubmit, the key in the URL changed but its still on the same page. From localhost:8080/#/?_k=iwio19 to localhost:8080/#/?_k=ldn1ew

Anyone know how to fix it? Appreciate it.

回答1:

I don't think routeActions are passed as props. What you want to do is this:

import { routeActions } from 'react-router-redux'

this.props.dispatch(routeActions.push('/foo'));

To provide a little more explicit answer and the answer to my own question in the comment.

Yes you can do

import { routeActions } from 'react-router-redux'

this.props.dispatch(routeActions.push('/foo));

However as I mentioned mapDispatchToProps will override this. To fix this you can bind the routeActions like so:

import { bindActionCreators } from 'redux'
import { routeActions } from 'react-router-redux'

function mapDispatchToProps(dispatch) {
    return {
        routeActions: bindActionCreators(routeActions, dispatch),
    }
}

export default connect(null, mapDispatchToProps)(YourComponent)

Now you can do: this.props.routeActions.push('/foo')

Just FYI this can be done even neater

function mapDispatchToProps(dispatch) {
    return {
        ...bindActions({routeActions, anotherAction}, dispatch)
    }
}

As for react-router-redux v4:

import { push } from 'react-router-redux';

export class ExampleContainer extends React.Component {
  static propTypes = {
    changeRoute: React.PropTypes.func,
  };

  function mapDispatchToProps(dispatch) {
    return {
      changeRoute: (url) => dispatch(push(url)),
      dispatch,
    };
  }
}

export default connect(null, mapDispatchToProps)(ExampleContainer);

then:

this.props.changeRoute('/foo');

I was able to get it working by doing this

import { connect } from 'react-redux'
import { bindActionCreators } from 'redux'
import { routeActions } from 'react-router-redux'

export const Cmpt = React.createClass({ //code })

function mapDispatchToProps(dispatch) {
  return bindActionCreators({
    push: routeActions.push,
    //all your other action creators here
  }, dispatch)
}

export const CmptContainer = connect({}, mapDispatchToProps)(Cmpt)

Then you can use push via props this.props.push('some/cool/route')

More Concisely

For these examples, I'd curry the mapDispatchToProps function like so:

bindActionDispatchers.js

import { bindActionCreators } from 'redux'

/** curries mapDispatchToProps with bindActionCreators to simplify React action dispatchers. */
export default function bindActionDispatchers(actionCreators) {
  if(typeof actionCreators === 'function')
    return (dispatch, ownProps) => bindActionCreators(actionCreators(ownProps), dispatch)
  return dispatch => bindActionCreators(actionCreators, dispatch)
}

Foo.js

import React from 'react'
import bindActionDispatchers from './bindActionDispatchers'
import { routeActions } from 'react-router-redux'
import * as appActions from './actions'

const Foo = ({ routeActions ...appActions }) => (
  <div>
    <button onClick={routeActions.push('/route')}>Route</button>
    <button onClick={appActions.hello('world')}>Hello</button>
  </div>
)

export default connect(null, bindActionDispatchers({ routeActions, ...appActions }))(Foo)

I packaged this into a lightweight npm package bind-action-dispatchers complete with unit tests and sanity checks. To use this version install with:

npm i -S bind-action-dispatchers

and import the function with:

import bindActionDispatchers from 'bind-action-dispatchers'
