概要 开发单页应用, 首先绕不开的内容就是路由, react router v4 版本是最新的版本. 和之前的版本相比, 成熟了很多, 也简单了很多, 使用起来更加方便. 核心 component react-router V4 可以用于 Web 和 Native. 这里主要讨论基于 Web 的应用. react-router 有很多 Components, 但是只要掌握下面 3 个 Component 就可以管理好 react 应用的路由了. Router component Router 是

React Router V4 正式版发布,该版本相较于前面三个版本有根本性变化,遵循 Just Component 的 API 设计理念. 本次升级的主要变更有: 声明式 Declarative 可组合 Composability 本次升级 React Router V4 吸取了 React 的理念:所有的东西都是 Component.因此 升级之后的 Route.Link.Switch……等都是一个普通的组件. React Router V4 基于 Lerna 管理多个 Repository

最近在学习React Router,但是网站的教程多半还是3.X版本之前的,所以我只能在GitHub上找到React Router的官方文档在读.后来总结了一下,包括学习经验以及V3.X与V4.X的差异.在实践练习React Router的时候,把这些经验总结全部写成了一个网站.所以在这个博客当中就不再详细叙述,大家点击下面链接就可以移步学习. GitHub源代码:https://github.com/zhongdeming428/react-router-demo GitHub Page De

前言 本文讲述怎么实现动态加载组件,并借此阐述适配器模式. 一.普通路由例子 import Center from 'page/center'; import Data from 'page/data'; function App(){ return ( <Router> <Switch> <Route exact path="/" render={() => (<Redirect to="/center" />)}

If a user has entered some input, or the current Route is in a “dirty” state and we want to confirm that data will be lost, React Router v4 provides a Prompt component to interrupt the Route transition and ask the user a question. For example we need

Overriding a browser's current location without breaking the back button or causing an infinite redirect can be tricky sometimes. In this lesson we'll learn how React Router v4 allows us to easily achieve a redirect without getting bogged down in bro

React Router v4 allows us to render Routes as components wherever we like in our components. This can provide some interesting use cases for creating dynamic routes on our applications. import React from 'react'; import { BrowserRouter as Router, Rou

We often want to render a Route conditionally within our application. In React Router v4, the Route components match the current route inclusively so a “stack” of Routes will all be processed. To render a single Route exclusively we can wrap them in

There are many cases where we will need a catch-all route in our web applications. This can include 404-style routes when nothing is match or other use cases where where we receive an invalid route in React Router v4. We can use 'Switch' from 'react-

With React Router v4 the entire library is built as a series of React components. That means that creating nested Routes is as simple as creating any other nested element in your application. Parent route: <NavLink to="/menu">Menu</NavL

React Router v4 ignores query parameters entirely. That means that it is up to you to parse them so that you can use that additional information as required. There are several strategies for doing this that we will look at. There are tow ways to pass

We can use regular expressions to more precisely define the paths to our routes in React Router v4. To add regex for router, we only need to add (), inside (), we can write regex: <Route path="/:date(\d{2}-\d{2}-\d{4}):ext(.[a-z]+)" children=

URLs can be looked at as the gateway to our data, and carry a lot of information that we want to use as context so that the user can return to a particular resource or application state. One way to achieve this is through the use of URL parameters th

We often need to be able to apply style to navigation links based on the current route. In React Router v4 you can easily accomplish this with the NavLink component. In this lesson, we will step through three ways to accomplish styling links through

网上关于React Router 4.0的按需加载文章有很多,大致的思路都一样,但是其实具体实现起来却要根据自己的实际情况来定,这里主要介绍一下我的实现方式. 主要方式是通过Route组件的render方法加载一个空的组件作为中间,通过空的组件用来加载具体的页面js文件,然后这个组件的内部加载完成的时候就使用webpack 的 import方法动态请求js,当js请求成功后,这个空组件显示具体的加载js内容,说起来比较晦涩,直接上代码. 1.先看看中间组件,(由于我这里使用了Typescript

传值方法 1.props.params 使用React router定义路由时,我们可以给指定一个path,然后指定通配符可以携带参数到指定的path: <Route path='/user/:name' component={UserPage}></Route> 跳转UserPage页面时,可以这样写: //link方法 <Link to="/user/sam">用户</Link> //push方法 this.props.history

If you’ve created several Routes within your application, you will also want to be able to navigate between them. React Router supplies a Link component that you will use to make this happen. Import Link: import { BrowserRouter as Router, Route, Link

React Router 4 has several routers built in for different purposes. The primary one you will use for building web applications is the BrowserRouter. In this lesson you will import the BrowserRouter and create some basic Route components. After create

cp from https://segmentfault.com/a/1190000010718620 几个月前,React Router 4 发布,我能清晰地感觉到来自 Twitter 大家对新版本中其 大量的修改 的不同声音.诚然,我在学习 React Router 4 的第一天,也是非常痛苦的,但是,这并不是因为看它的 API,而是反复思考使用它的模式和策略,因为 V4 的变化确实有点大,V3 的功能它都有,除此之外,还增加了一些特性,我不能直接将使用 V3 的心得直接迁移过来,现在,我必

今天,我们要讨论的是react router中Link传值的三种表现形式.分别为通过通配符传参.query传参和state传参. ps:进入正题前,先说明一下,以下的所有内容都是在react-router V4的版本下. 1.通配符传参 Route定义方式: <Route path='/path/:name' component={Path}/> Link组件: <Link to="/path/通过通配符传参">通配符</Link> 参数获取: th
