cp from : https://www.jianshu.com/p/6a45e2dfc9d9 万恶的根源 距离React Router v4 正式发布也已经过去三个月了,这周把一个React的架子做了升级,之前的路由用的还是v2.7.0版的,所以决定把路由也升级下,正好“尝尝鲜”... 江湖传言,目前官方同时维护 2.x 和 4.x 两个版本.(ヾ(｡ꏿ﹏ꏿ)ﾉﾞ咦,此刻相信机智如我的你也会发现,ReactRouter v3 去哪儿了?整丢了??巴拉出锅了???敢不敢给我个完美的解释!?)事…

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…

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…

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…

PS:react-route就是一个决定生成什么父子关系的组件,一般和layout结合起来,保证layout不行,内部的子html进行跳转 你会发现,它不是一个库,也不是一个框架,而是一个庞大的体系.想要发挥它的威力,整个技术栈都要配合它改造.你要学习一整套解决方案,从后端到前端,都是全新的做法. 举例来说,React 不使用 HTML,而使用 JSX .它打算抛弃 DOM,要求开发者不要使用任何 DOM 方法.它甚至还抛弃了 SQL ,自己发明了一套查询语言 GraphQL .当然,这些你都可…

一.基本用法 React Router 安装命令如下. $ npm install -S react-router 使用时,路由器Router就是React的一个组件. import { Router } from 'react-router'; render(<Router/>, document.getElementById('app')); Router组件本身只是一个容器,真正的路由要通过Route组件定义. import { Router, Route, hashHistory }…

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…

React是个技术栈,单单使用React很难构建复杂的Web应用程序,很多情况下我们需要引入其他相关的技术 React Router是React的路由库,保持相关页面部件与URL间的同步 下面就来简单介绍其基础使用,更全面的可参考 指南 1. 它看起来像是这样 在页面文件中 在外部脚本文件中 2. 库的引入 React Router库的引入,有两种方式 2.1 浏览器直接引入 可以引用 这里 的浏览器版本,或者下载之后引入 然后就可以直接使用 ReactRouter 这个对象了,我们可能会使用到…

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…

在这个教程里,我们会从一个例子React应用开始学习react-router-dom.其中你会学习如何使用Link.NavLink等来实现跳转,Switch和exact实现排他路由和浏览器路径历史. 也许学习react-router最好的办法就是用react-router-dom v4来写一个多页的react应用.这个react应用会包含登录.注册.首页.联系人等页面.但是,首先让我们来看一下react router v4的概念,以及它与v3有什么不同的地方. React router v4 v…

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…

在网络工程中,路由能保证信息从源地址传输到正确地目的地址,避免在互联网中迷失方向.而前端应用中的路由,其功能与之类似,也是保证信息的准确性,只不过来源变成URL,目的地变成HTML页面. 在传统的前端应用中,每个HTML页面都会对应一条URL地址,当访问某个页面时,会先请求服务器,然后服务器根据发送过来的URL做出处理,再把响应内容回传给浏览器,最终渲染整个页面.这是典型的多页面应用的访问过程,由服务器控制页面的路由,而其中最令人诟病的是整页刷新,不仅存在着资源的浪费(像导航栏.侧边栏等通用部分…
