有时我看到了众所周知的警告browser.js:49 Warning: [react-router] You cannot change <Router routes>; it will be ignored
,我发现了两个趋势问题,朋友们讨论过这个问题,解决方案是const
路由组件并将它们放在Router
组件中。
https://github.com/ReactTraining/react-router/issues/2704
https://github.com/reactjs/react-router-redux/issues/179
如下所示:
您会看到使用此代码发出警告:
class Root extends Component {
render() {
return (
<Router history={browserHistory} createElement={this.createElement}>
<Route component={App}>
<Route path="/" component={MainPage}/>
<Route path="/page2" component={Page2}/>
<Route path="/settings" component={SettingsPage}/>
</Route>
</Router>
)
}
}
但您不会看到此代码的警告:
const routes = (
<Route component={App}>
<Route path="/" component={MainPage}/>
<Route path="/page2" component={Page2}/>
<Route path="/settings" component={SettingsPage}/>
</Route>
);
class Root extends Component {
render() {
return (
<Router history={browserHistory} createElement={this.createElement}>
{routes}
</Router>
)
}
}
这是一个很好的解决方案,可以消除[react-router]警告,对于Root Component
更改state
,routes
是静态的,你不会看到任何警告。 但是 我的问题是:我将Root Component
道具传递给每个Route
,我无法执行上述解决方案,
我必须将App Route
放在路由器中,所以这个方法绝对不是解决方法,我会再次看到已知的警告,请参阅我的路由器代码:
export default class AppRoutes extends Component {
render() {
return (
<Router history={hashHistory}>
<Route path="/" {...this.props} component={App}>
<IndexRoute component={Home} {...this.props}/>
<Route path="/transaction" component={Transaction} {...this.props}/>
<Route path="/users-management" component={UsersManagement} {...this.props}/>
<Route path="/issues" component={Issues} {...this.props}/>
<Route path='/not-found' component={NotFound}/>
<Route path='/settlement-management' component={SettlementManagement} {...this.props}/>
<Route path='/categories-management' component={CategoriesManagement} {...this.props}/>
<Route path='/gifts-management' component={GiftsManagement} {...this.props}/>
<Redirect from='/*' to='/not-found'/>
</Route>
</Router>
);
}
}
Root Component
呈现代码为:
render(){
return(
<AppRoutes {...this}/>
);
}
我将此作为道具传递给AppRoutes
组件,我需要将继承的this.props
传递给子Route
并使用它们。我怎么能看到警告并将道具传递给任何Route
?
我的一个解决方案是,我将所有Route
写为静态,并在每个组件内直接调用Root Component
props
,但是如何?我不知道如何调用并props
Root Component
props
Root Component
Root Component
get()
$arr = [];
Log::info(json_encode($request->get('emptyArray',$arr)));
{{1}} {{1}} {{1}}孩子们?
答案 0 :(得分:0)
您可以使用render
路线道具代替component
将道具传递给您的组件:
<Route path="/transaction" render={() => <Transaction {...this.props} />} />
编辑:或者这也传递路径道具:
<Route path="/transaction" render={(routeProps) => <Transaction parentProps={this.props} {...routeProps} />} />
(我认为最好将单个自定义父道具传递给不与routeProps冲突)
