您想要如何應(yīng)用條件邏輯來(lái)基於使用者互動(dòng)顯示/渲染內(nèi)容是主觀的，但您有多種選擇。

使用本機(jī)狀態(tài)

使用本地狀態(tài)似乎沒問題，但我會(huì)警告你，在狀態(tài)中儲(chǔ)存 JSX、儲(chǔ)存一些資料（例如對(duì)元件的引用）並映射它被認(rèn)為是 React 反模式聲明你想要渲染的 JSX。

範(fàn)例：

const QUERY_CONTENT = {
  QueryExecutor,
  QueryIndicators,
}

const Login = () => {
  const REACT_VERSION = React.version;

  const [collapsed, setCollapsed] = useState(true);
  const [QueryContent, setQueryContent] = useState(QUERY_CONTENT.QueryIndicators);

  return (
    <Layout className="layout">
      <Sider
        className="layout__sider"
        collapsible
        collapsed={collapsed}
        onCollapse={value => setCollapsed(value)}
      >
        <Menu
          mode="inline"
          defaultSelectedKeys={['1']}
          className="layout__sider-menu"
        >
          <Menu.Item
            key="1"
            icon={<HomeTwoTone twoToneColor={'#184287'} />}
            onClick={() => setQueryContent(QUERY_CONTENT.QueryIndicators)}
          >
            Home
          </Menu.Item>
          <Menu.Item
            key="2"
            icon={<PlayCircleOutlined />}
            onClick={() => setQueryContent(QUERY_CONTENT.QueryExecutor)}
          >
            Executor
          </Menu.Item >          
        </Menu>
      </Sider>

      <Layout>
        <Header className="layout__header">
          {React.createElement(
            collapsed ? MenuUnfoldOutlined : MenuFoldOutlined,
            {
              className: 'trigger',
              onClick: () => setCollapsed(collapsed => !collapsed)
            }
          )}
          <h1
            className="layout__header-text"
            title={'React:' + REACT_VERSION}
          >
            POA Console HOME
          </h1>
        </Header>
        <Content className="layout__content">
          <QueryContent />
        </Content>
      </Layout>
    </Layout>
  );
};

使用路線

如果您想使用react-router 和路由來(lái)管理內(nèi)容的條件渲染，則將該元件轉(zhuǎn)換為佈局元件，該佈局元件會(huì)為嵌套渲染一個(gè)Outlet元件要渲染的路線。路由器/路由將管理路由匹配並渲染特定的路由內(nèi)容。

範(fàn)例：

import { Outlet, useNavigate } from 'react-router-dom';

const REACT_VERSION = React.version;

const AppLayout = () => {
  const navigate = useNavigate();

  const [collapsed, setCollapsed] = useState(true);

  return (
    <Layout className="layout">
      <Sider
        className="layout__sider"
        collapsible
        collapsed={collapsed}
        onCollapse={setCollapsed}
      >
        <Menu
          mode="inline"
          defaultSelectedKeys={['1']}
          className="layout__sider-menu"
        >
          <Menu.Item
            key="1"
            icon={<HomeTwoTone twoToneColor={'#184287'} />}
            onClick={() => navigate("/queryIndicators")}
          >
            Home
          </Menu.Item>
          <Menu.Item
            key="2"
            icon={<PlayCircleOutlined />}
            onClick={() => navigate("/queryExecutor")}
          >
            Executor
          </Menu.Item >          
        </Menu>
      </Sider>

      <Layout>
        <Header className="layout__header">
          {React.createElement(
            collapsed ? MenuUnfoldOutlined : MenuFoldOutlined,
            {
              className: 'trigger',
              onClick: () => setCollapsed(collapsed => !collapsed)
            }
          )}
          <h1
            className="layout__header-text"
            title={'React:' + REACT_VERSION}
          >
            POA Console HOME
          </h1>
        </Header>
        <Content className="layout__content">
          <Outlet /> // <-- nested routes render here
        </Content>
      </Layout>
    </Layout>
  );
}

import { Routes, Route } from 'react-router-dom';

const App = () => {
  ...

  return (
    ...
    <Routes>
      ...
      <Route element={<AppLayout />}>
        ...
        <Route path="/queryIndicators" element={<QueryIndicators />} />
        <Route path="/queryExecutor" element={<QueryExecutor />} />
        ...
      </Route>
      ...
    </Routes>

  );

import { BrowserRouter as Router } from 'react-router-dom';
