为什么不清楚MenuItem如何导航到其他路线?
例如,当点击菜单项时,我想路由到“/account”
我可以使用 onclick 函数设法实现这一点,但我相信有更简单的方法。请告诉我它我想在我的项目中实现它。
顺便说一句,当使用 containerElement 时,containerElement={<Link to="/dashboard" />}
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.

当我通过以下方式修复该错误时containerElement
->containerelement
错误消失了,这是一个好消息,但坏消息是菜单不符合链接中提到的死记硬背!

更新
我发现了另一个由@Gavin Thomas 先生在下面提出的解决方案引起的问题,该解决方案引用了 SO 上的帖子。问题是 using 只是将提到的“to”属性值放在链接到现有路由的 URL 中,而不去该路径,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,而无需在 nodejs 后端服务器的注销路由上访问!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,我猜是因为 和 之间的区别!
所以请帮我解决第二个问题!
