我正在构建一个React应用,当URL更改时我需要更改一个组件。
这是我的app.js:
ReactDOM.render(
<Provider store={Store}>
<BrowserRouter>
<App />
</BrowserRouter>
</Provider>
, document.getElementById('root'));
Main.js
export default class Main extends Component {
render() {
return(
<div className="d-flex flex-column col-md-12 col-lg-10 p-0 bg-f8f6f9">
<div className="box-header">
<div className="container-edit">
<MainMenu/>
</div>
</div>
<Pagina/>
</div>
);
}
}
MainMenu.js
...
<Router>
...
<Link className="dropdown-item" to="/administrativo/cadastro/grupos">Grupos</Link>
...
</Router>
...
Pagina.js(负责加载特定页面的组件)
export default class Pagina extends Component {
render() {
return(
<div id="page">
<Router>
<Switch>
<Route path="/administrativo/cadastro/grupos" component={AdministrativoGrupos} />
</Switch>
</Router>
</div>
);
}
}
我要加载的“组件”是AdministrativoGrupos
,但是当我单击此URL的<Link>
时,没有任何反应。
我已经在exact
上尝试过<Link>
,但没有任何变化。
一个有趣的事实:如果我单击<Link>
,则什么也没有发生。之后,如果我单击<a href="#">
,该组件将正常加载。
有什么建议吗?
编辑:AdministrativoGrupos 从'react'导入React,{组件};
export default class AdministrativoGrupos extends Component {
render() {
return(
<div className="w-80 ml-auto mr-auto mt-4">
<div className="row">

我无法测试您的部分代码片段,但我会指出一些我认为可能引起问题的东西:
exact
上使用Link
。 exact
中有Route
个道具
组件。Link
组件周围
Router
。如果没有,请重试。点击Link
后,您的网址至少也改变了吗?
让我知道这是否对您有帮助。
