Question

为什么不清楚MenuItem如何导航到其他路线？

例如，点击菜单项时，我想路由到＆＃39; / account＆＃39;

我可以设法使用onclick功能实现这一点，但我确信有一种更简单的方法。请告诉我，我想在我的项目中实现它。

顺便说一下，当使用containerElement containerElement={<Link to="/dashboard" />}时，我收到以下错误：

index.js:2177 Warning: React does not recognize the `containerElement` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `containerelement` instead. If you accidentally passed it from a parent component, remove it from the DOM element.

当我通过containerElement - ＆gt;修正错误时containerelement错误消失了，这是一个好消息，但坏消息是菜单中没有提到链接中提到的死记硬背！

我发现由@Gavin Thomas先生提出的解决方案引起的另一个问题是指SO上的帖子。问题是，使用只是将提到的＆＃39;添加到＆＃39;链接到现有路由的URL中的属性值，而不是指向该路径，即

<MenuItem onTouchTap={() => {this.handleClose()}}><NavLink to="/api/logout">Sign Out</NavLink></MenuItem>

最终将浏览器上的链接设为http://localhost： 3000 / logout，而不是在nodejs后端服务器的注销路径上进行操作！这是一个问题。

请注意，我使用代理从 3000 指向 5000 ，如下所示

 "proxy": {
    "/api/*": {
      "target": "http://localhost:5000"
    }
  },

一般来说，我猜这是因为和之间的区别！

所以请帮我解决第二个问题！

Answer 1

您应该使用component属性。可以使用react-router-dom中的Link组件：

<MenuItem component={Link} to="/logout">
  Logout
</MenuItem>

{0}中使用了containerElement属性，v1中不再存在该属性。

请参阅MenuItem

的文档

Answer 2

这是我们发现的......

您现在需要使用＆lt; NavLink＆gt; vs Link

React material-ui MenuItem containerElement not working

import React, { Component } from 'react';
import { NavLink } from 'react-router-dom'
import Menu from 'material-ui/Menu';
import MenuItem from 'material-ui/MenuItem';
import Drawer from 'material-ui/Drawer'

    <Drawer
         docked={false}
         open={this.state.open}
         onRequestChange={(open) => this.setState({open})}>
         <MenuItem onTouchTap={() => {this.handleClose()}} >
              <NavLink to="/">Home </NavLink>
         </MenuItem>
         <MenuItem onTouchTap={() => {this.handleClose() }} >
              <NavLink to="/about"> About Us </NavLink>
         </MenuItem>
    </Drawer>
