Is there a way to access the React tree down a component from within it? For instance when I use the React-devtool extension I am able to navigate along the React tree. Is it possible to do such navigation from within the code of a component to know everything below it? I know about children, but it does not work when parents components simply render children components, ie in Parent componen
有没有办法从内部访问React树中的一个组件？ 例如，当我使用React-devtool扩展时，我可以沿着React树进行导航。 是否有可能从组件的代码中进行这种导航，以了解它下面的所有内容？ 我知道孩子，但父母组件只是呈现儿童组件时，它不起作用，即在Parent组件中，我有类似的东西 render() { <Child1 /> } 然后在我拥有的Child1组件中 render() { <Child2 /> } 等等 我想从知道Paren
I am building a simple static view-engine using React with the goal of rendering static HTML-markup and generating a js-file filled with that components DOM-events (onClick, etc). The way I'm doing the first part is to require a specified JSX-file which, for example, looks like this: import React from 'React'; export default class Test extends React.Component { clicked() { al
我使用React构建了一个简单的静态视图引擎，其目标是呈现静态HTML标记并生成一个填充了组件DOM事件（onClick等）的js文件。 我做第一部分的方式是需要一个指定的JSX文件，例如，看起来像这样： import React from 'React'; export default class Test extends React.Component { clicked() { alert('Clicked the header!'); } render() { return ( <html> &
I'm making a small Video component in React (for you guessed it, playing videos) and I want to embed that component inside a parent component and then be able to call a play method on the video component. My video component looks like: import React, { Component, PropTypes } from 'react'; import ReactDOM from 'react-dom'; const { string, func } = PropTypes; export default class Video exten
我在React中制作了一个小的Video组件（因为你猜对了，正在播放视频），我想将该组件嵌入到父组件中，然后能够在视频组件上调用play方法。 我的视频组件如下所示： import React, { Component, PropTypes } from 'react'; import ReactDOM from 'react-dom'; const { string, func } = PropTypes; export default class Video extends Component { static propTypes = { source: string.isRequired, type: string.i
I have a React application with Components written in ES6 - transpiled via Babel and Webpack. In some places I would like to include specific CSS files with specific Components, as suggested in react webpack cookbook However, if in any Component file I require a static CSS asset, eg: import '../assets/css/style.css'; Then the compilation fails with an error: SyntaxError: <PROJ
我有一个使用ES6编写的组件的React应用程序 - 通过Babel和Webpack传输。 在一些地方，我想包含特定的CSS文件和特定的组件，如反应webpack食谱中所建议的 但是，如果在任何组件文件中需要静态CSS资源，例如： import '../assets/css/style.css'; 然后编译失败并出现错误： SyntaxError: <PROJECT>/assets/css/style.css: Unexpected character '#' (3:0) at Parser.pp.raise (<PROJECT>node_modu
When I use react router with Redirect, Link or NavLink eveything is fine. But I need a function that navigates me to a route programmatically. That is what I want : if(a == 1){ this.context.history.push("/") } else { this.contetx.history.push("/home"); } As you see context history is not exists in react router v4 any more. I cannot write withroute in js code for navigation. Can any
当我使用Redirect的反应路由器时，Link或NavLink eveything都可以。 但是我需要一个能够以编程方式导航到路线的功能。 这就是我想要的： if(a == 1){ this.context.history.push("/") } else { this.contetx.history.push("/home"); } 正如你所看到的，上下文历史在反应路由器v4中不再存在。 我无法使用js代码导航编写路由。 任何人都可以说我如何直接在js代码中导航？ 谢谢 路由器会为你的道具添加history
New to React and having troubles trying to create a persistent navigation across my application using React-Router. Using the create-react-app and "react-router": "^3.0.2" I'm trying to just have a Navigation on the top of the page with a couple of links. The error I keep getting is Uncaught Error: <Link>s rendered outside of a router context cannot navigate.
React的新手和尝试使用React-Router在我的应用程序中创建持久导航的麻烦。 使用create-react-app和"react-router": "^3.0.2" 我正在尝试在页面顶部添加一些导航，并附带一些链接。 我一直收到的错误是Uncaught Error: <Link>s rendered outside of a router context cannot navigate. index.js： import React from 'react'; import ReactDOM from 'react-dom'; import { browserHistory } fro
I'm exploring possibilities of React Native while developing a demo app with custom navigation between views with the help of Navigator component - http://facebook.github.io/react-native/docs/navigator.html#content The main app class renders navigator and inside renderScene returns passed component: class App extends React.Component { render() { return ( <Navigat
我正在探索React Native的可能性，同时在Navigator组件的帮助下开发一个在视图之间定制导航的演示应用程序 - http://facebook.github.io/react-native/docs/navigator.html#content 主应用程序类呈现导航器，并在renderScene返回传递的组件： class App extends React.Component { render() { return ( <Navigator initialRoute={{name: 'WelcomeView', component: WelcomeView}}
I have been thinking and I am confused with the routing between Client and Server. Suppose I use ReactJS for server-side rendering before sending the request back to web browser, and use react-router as a client-side routing to switch between pages without refreshing as SPA. What comes to mind is: How are the routes interpreted? For example, a request from Home page ( /home ) to Posts page
我一直在想，我对客户端和服务器之间的路由感到困惑。 假设我在将请求发送回Web浏览器之前使用ReactJS进行服务器端渲染，并使用react-router作为客户端路由在页面之间进行切换，而无需刷新SPA。 想到的是： 路线如何解释？ 例如，从主页（ /home ）到帖子页面（ /posts ）的请求， 路由在服务器端或客户端上到达哪里？ 它如何知道它是如何处理的？ 请注意，这个答案涵盖了React Router版本0.13.x--即将到来的版本1.0
I am using react-router 2.4.0 and want to link to another route programmatically (what I did before using <Link> ). It's explained nicely in this SO post where they say in 2.4.x you should use the decorator pattern with withRouter , so I am using the following code: import {withRouter} from 'react-router' // further imports omitted class CreateJobItemFormRaw extends React.Component
我正在使用react-router 2.4.0并且希望以编程方式链接到另一条路由（我在使用<Link>之前所做的）。 在这个SO帖子里很好的解释了他们在2.4.x说你应该在withRouter使用装饰器模式，所以我使用下面的代码： import {withRouter} from 'react-router' // further imports omitted class CreateJobItemFormRaw extends React.Component { ... } const CreateJobItemForm = withRouter(CreateJobItemFormRaw) export defa
I have the following structure for my React.js application using React Router: var Dashboard = require('./Dashboard'); var Comments = require('./Comments'); var Index = React.createClass({ render: function () { return ( <div> <header>Some header</header> <RouteHandler /> </div> ); } }); var routes = ( <Route
对于使用React Router的React.js应用程序，我有以下结构： var Dashboard = require('./Dashboard'); var Comments = require('./Comments'); var Index = React.createClass({ render: function () { return ( <div> <header>Some header</header> <RouteHandler /> </div> ); } }); var routes = ( <Route path="/" handler={Index
