使用 reactjs 和 react-router，我可以显示组件或 {this.props.children} 吗？

Question

Here is the scenario: I have a bunch of components that I allow certain words to be clicked, which will link to a reference page/component.

If the highlighted words are not clicked, I simply display the component (which mind you, there are many of them that allow this mechanism and a whole menu of them on the side).

Here is the current code:

//app.js
ReactDOM.render(
  <Router history={hashHistory}>
    <Route path="/" component={App} handler={App}>
        <IndexRoute component={Index}/>
         <Route path="help" component={HelpPage}>
            <Route path="/help/reference" component={ReferenceComponent}></Route>
        </Route>

    </Route>
  </Router>,
  destination
);

//help.js:
export default class HelpPage extends Component {
    render() {
        return (
            <Grid>
                <Title/>
               <Row className="show-grid">
                   <Col lg={2} md={4} sm={4}>
                        <HelpMenu
                            getBtnId={this.getBtnId}
                        />
                   </Col>
                   <Col lg={10} md={8} sm={8}>
//part that most matters (currently doesnt work)
                       {<HelpPanels panelIndex={this.state.panelIndex}/> ||
                       this.props.children}
                   </Col>

               </Row>
           </Grid>

        )
    }
}

I commented right above the part that most matters when rendering my HelpPage component.

I understand that what I am trying to do currently doesn't work. What I want is basically either you post one of the page's components, or if you are in the .../help/reference route you post that Reference component. Is there any way I can do this? I've messed around with it a bit, but so far, nothing.

Just change your route config so that according to the selected index you can show HelpPanels as child route under HelpPage and for reference route you show ReferenceComponent . Since reference route is a child route of help route you don't need to explicitly write full path as /help/reference in the config object.

ReactDOM.render(
  <Router history={hashHistory}>
    <Route path="/" component={App} handler={App}>
        <IndexRoute component={Index}/>
         <Route path="help" component={HelpPage}>
            <Route path="details/:helpId" component={HelpPanels}/>
            <Route path="reference" component={ReferenceComponent}></Route>
        </Route>

    </Route>
  </Router>,
  destination
);

Then just display {this.props.children} under HelpPage Component.

export default class HelpPage extends Component {
    render() {
        return (
            <Grid>
                <Title/>
               <Row className="show-grid">
                   <Col lg={2} md={4} sm={4}>
                        <HelpMenu
                            getBtnId={this.getBtnId}
                        />
                   </Col>
                   <Col lg={10} md={8} sm={8}>
//if the route is /help/reference the children will be `ReferenceComponent` component or if it is something in the format /help/details/3 it will show `HelpPanels` component and this.props.params.helpId will be 3.
                       {this.props.children}
                   </Col>

               </Row>
           </Grid>

        )
    }
}
