如何为不同的 reactjs 页面显示不同的导航栏组件 [英] How to display different navbar component for different reactjs pages

问题描述

我正在尝试显示两种不同的导航栏组件，一种作为主站点导航栏，另一种用于仪表板导航栏.

I am trying to display two different navbar component one as the main site navbar and one for the dashboard navbar.

我尝试创建两个可重用的组件，即:

I have tried creating two reusable components namely:

和

这是他们的实现:

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

对于 LayoutDashboardNav 也是一样的，我只是将 改为 下面是我的路线实施:

it is the same for LayoutDashboardNav i only changed <Navbar /> to <DashboardNav /> below is my route implementation:

<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>

我希望看到 <Navbar/> 或 <DashboardNav/> 仅在作为它们使用的组件的子页面的那些页面上.但是一切都只显示 .

I expect to see <Navbar /> or <DashboardNav /> only on those pages that are children of the components they are used in. But everything is showing only <Navbar />.

推荐答案

你可以像这样使用高阶组件来包裹 组件.我们可以让包装器组件有一些逻辑来根据 layout 属性确定使用哪个布局.

You can use a a higher order component to wrap the <Route> component like this. We can have the wrapper component to have some logic to determine which layout to use based on layout prop.

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

而不是做正常的<路由精确路径="/selectseat";组件={PickSeat}/>

现在你可以做<DynamicLayoutRoute 精确路径=/selectseat";组件={PickSeat} 布局=DASH_BOARD_NAV"；/>
