你必须把使用useNavigate钩子的组件包裹在一个Router中。 // App.test.js import {render} from '@testing-library/react'; import App from './App'; import {BrowserRouter as Router} from 'react-router-dom'; // 👇️ wrap component that uses useNavigate in Router test('renders react component...
当我们尝试在react router的Router上下文外部使用useNavigate 钩子时,会产生"useNavigate() may be used only in the context of a Router component"警告。为了解决该问题,只在Router上下文中使用useNavigate 钩子。usenavigate-may-be-used-only-in-the-context-of-router.png ...
当我们尝试在react router的Router上下文外部使用useNavigate钩子时,会产生"useNavigate() may be used only in the context of a Router component"警告。为了解决该问题,只在Router上下文中使用useNavigate钩子。 下面是一个在index.js文件中将React应用包裹到Router中的例子。

可以使用BrowserRouter的方法来实现,在没有路由路径的情况下使用useNavigate 具体示例: import { BrowserRouter, useNavigate } from 'react-router-dom' function MyComponent() { const navigate = useNavigate() const handleClick = () => { navigate('/about') } return ( Go to About page ) } ...
import React from 'react'; import { BrowserRouter as Router, Route, Switch } from 'react-router-dom'; import Home from './Home'; import About from './About'; function App() { return ( <Router> <Switch> <Route exact path="/" component={Home} /> <Route path="/about" component=...
