隐藏特定页面上的组件

Question

我有这种结构：

        <Router onUpdate= {scrollToTop} history={history}>
        <div>
        <Navbar/> 

          <ScrollToTopRoute exact path="/" component={home} />
          <ScrollToTopRoute path="/fund" component={fund} />
          <ScrollToTopRoute path="/browseideas" component={browseideas} />
          <ScrollToTopRoute path="/earnwithus" component={earnwithus} />
          <ScrollToTopRoute path="/register" component={RegisterPage} />
          <ScrollToTopRoute path="/login" component={LoginPage} />

          <ScrollToTopRoute path="/idea" component={idea} />

          <ScrollToTopRoute path="/lightning" component={Lightning} />
          <ScrollToTopRoute path="/storm" component={Storm} />
          <ScrollToTopRoute path ="/increase" component ={increase}/>
          <ScrollToTopRoute path ="/policy" component ={policyprivacy}/>

          <PrivateRoute path ="/homepage" component ={homepage}/>

          <PrivateRoute path ="/activehedges" component ={ActiveHedges}/>
          <PrivateRoute path ="/userprofile" component ={UserProfile}/>
          <PrivateRoute path ="/myfunds" component ={MyFunds}/>

          <PrivateRoute path ="/deposit" component ={deposit}/>
          <PrivateRoute path ="/withdraw" component ={withdraw}/>

        <Footer/>
        </div>
      </Router>

Navbar＆Footer应该在每个页面上，而不是RegisterPage和LoginPage。

如何以与添加到每个页面不同的方式隐藏<Navbar/> <Footer/>，这是推荐的做法吗？

Answer 1

您可以使用某些默认状态，设置类似registered：false

在您的父组件中：

this.state = { registered: false };

然后，在<Navbar/>和<Footer/>中，检查注册是否为false或true：

if(!this.state.registered){
   // Hide component
} else {
   // Show component
}

当然，一旦用户注册，您需要将注册设置为true
