Question

我试图显示两个不同的导航栏组件，一个作为主站点导航栏，另一个显示为仪表板导航栏。

我尝试创建两个可重用组件，即：

<LayoutNav />和<DashboardNav />

这是它们的实现：

const LayoutNav = ({children}) => {
    return (
        <>
            <section className="container-fluid">
                <Navbar />
                {children}
            </section>
        </>
    );
}

对于LayoutDashboardNav来说是一样的，我只是将<Navbar />更改为<DashboardNav />，以下是我的路由实现：

<BrowserRouter>
        <Switch>
            <LayoutNav>
                <Route exact path="/registervehicle" component={RegVehicle} />
                <Route exact path="/result" component={SearchResults} />
                <Route exact path="/selectseat" component={PickSeat} />
                <Route exact path="/forgotpassword" component={ForgotPassword} />
                <Route exact path="/resetpassword" component={ResetPassword} />
                <Route exact path="/register" component={Registration} />
                <Route exact path="/login" component={LoginAuth} />
                <Route exact path="/" component={Home} />
            </LayoutNav>

            <LayoutDashboardNav>
                <Route exact path="/companydashboard" component={CompanyDashboard} />
            </LayoutDashboardNav>

            <Route component={NotFound} />
        </Switch>
        <Footer />
    </BrowserRouter>

我希望仅在这些页面所属的页面上看到<Navbar />或<DashboardNav />。但是所有内容仅显示<Navbar />。

您可以使用更高阶的组件来包装<Route>组件，如下所示。我们可以使包装器组件具有一些逻辑，以便根据layout属性来确定使用哪种布局。

// wrapper component
const DynamicLayoutRoute = props => {
  const { component: RoutedComponent, layout, ...rest } = this.props;

  // render actual Route from react-router
  const actualRouteComponent = (
    <Route
      {...rest}
      render={props => (
         <RoutedComponent {...props} />
      )}
    />
  );

  // depends on the layout, you can wrap Route component in different layouts
  switch (layout) {
    case 'NAV': {
      return (
        <LayoutNav>
          {actualRouteComponent}
        </LayoutNav>
      )
    }
    case 'DASH_BOARD_NAV': {
      return (
        <LayoutDashboardNav>
          {actualRouteComponent}
        </LayoutDashboardNav>
      )
    }
    default: {
      return (
        <LayoutNav>
          {actualRouteComponent}
        </LayoutNav>
      )
    }
  }
  return (
    <Route
      {...rest}
      render={props => (
        userContext && <RoutedComponent {...props} />
      )}
    />
  );
};

代替正常 <Route exact path="/selectseat" component={PickSeat} />

现在您可以做 <DynamicLayoutRoute exact path="/selectseat" component={PickSeat} layout="DASH_BOARD_NAV" />
