Question

我有这种类型的结构：

        <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>

导航栏和页脚应该在每个页面上，而不是RegisterPage和LoginPage。

如何隐藏<Navbar/> <Footer/> 与添加到每个页面的方式不同，这是推荐做法吗？

Answer 1

您可以使用一些默认的状态，设置类似 registered：false

的内容。

在您的父组件中：

<Navbar/>

然后，在<Footer/>和if(!this.state.registered){ // Hide component } else { // Show component }内，检查注册是否为假或真：

Uncaught SyntaxError: missing ) after argument list

当然，一旦注册了用户，就需要将注册设置为true

隐藏特定页面上的组件
