我是新来的反应者,我想知道如何更改链接/按钮上的单击页面,我已经尝试过以下npm软件包:react-router-dom
问题是,当我单击链接时,URL条目中的路径更改了,但是页面保持不变,这是登录页面代码:
import React, { Component } from "react";
import "jquery/dist/jquery.min.js";
import "bootstrap/dist/js/bootstrap.min.js";
import global from "../resource/global.json";
import { BrowserRouter as Router, Link } from "react-router-dom";
<div className="row" style={{ margin: "auto" }}>
<div className="row float-left" style={{ margin: "auto" }}>
<Router>
<Link
to={""}
style={{
marginRight: "15px",
border: "none",
color: global.GUI.GRIGIOSCURO,
backgroundColor: "transparent",
textAlign: "center",
textDecoration: "none",
display: "inline-block"
}}
>
Home
</Link>
<Link
to={"/terms"}
style={{
marginRight: "15px",
border: "none",
color: global.GUI.GRIGIOSCURO,
backgroundColor: "transparent",
textAlign: "center",
textDecoration: "none",
display: "inline-block"
}}
>
Termini e Condizioni
</Link>
<Link
to={"/terms"}
style={{
backgroundColor: "transparent",
marginRight: "15px",
border: "none",
color: global.GUI.GRIGIOSCURO,
textAlign: "center",
textDecoration: "none",
display: "inline-block"
}}
>
Privacy
</Link>
</Router>
</div>
这是我的项目目录:
public
|_icon.ico
|_index.html
|_manifest.json
|_src
|_component
|_landing.jsx
|_login.jsx
|_terms.jsx
我只想点击链接按钮从登陆到条款,有什么建议吗?难道我做错了什么?谢谢

react-router用于根据url更改页面的组件是<Route>
。在示例代码中,您没有这些,因此您的页面将永远不会改变。通过路由,您可以指定当url匹配特定模式时,您希望呈现特定组件。
例如,在快速入门部分(found here)中提到了路线渲染
{/* A <Switch> looks through its children <Route>s and
renders the first one that matches the current URL. */}
<Switch>
<Route path="/about">
<About />
</Route>
<Route path="/users">
<Users />
</Route>
<Route path="/">
<Home />
</Route>
</Switch>
如果url匹配<About/>
,则该代码将呈现"/about"
组件;如果url匹配<Users/>
,则该代码将呈现"/users"
组件;否则,将呈现<Home/>
