In this lesson we'll learn how to render multiple component children from a single route.Define a named component by ' components ':headerbody: otherbody}}>The ' header ' and ' body ' are the key.Render:Const Container = (props) = ------------------Import React from ' React 'Import {hashhistory, Route, Router, Link, Indexroute} from' React-router '; Const Home= (
down many levels. This could mean a lot of maintenance if things need to the change.The second problem is and in this setup, the app is being placed inside the router through a call to This.props.children. We can ' t just add props onto the app component in our render function. The "we ' re going to handle" is through React ' s context mechanism.Import React, {Component} from '

There is a lot of can do with the React Native Navigator. Here, I'll try to go through a few examples of what you can do with the Navigator and explain about it all works in depth.In React Native you have both choices as of now for Navigation (only one cross platform) out of the box, as well as the EXN Avigator from Exponent. We'll focus on the main Navigator component as that's what's most questions I had
Preface:
because mixin is contrary to JavaScript semantics, React ES6 uses higher-order components instead of mixins. In This section, we will focus on how to replace the traditional React mixins with higher-order components. How do we use ES6 to handle mixin?
What is a high-order component?
Adding logic to an existing component class through a function is a higher-order component.A higher-order component
JSX is not a new development language, but a syntax proposed by Facebook: A syntactic sugar that allows you to directly write HTML tags in JavaScript code. Therefore, JSX is essentially a JavaScript language.
TIPS: syntaxes (Syntactic sugar) is by British computing scientist Peter randing (https://zh.wikipedia.org/wiki/% E5 % BD % BC % E5 % BE % 97% C2 % B7 % E5 % 85% B0 % E4 % B8 % 81) A term invented is a syntax added to a computer language. This syntax does not affect the functions of the lan
JSX is not a new development language, but a syntax scheme that Facebook proposes: a syntactic sugar that can write HTML tags directly in JavaScript code, so JSX is essentially a JavaScript language.
Tip: syntax sugar (syntactic sugar) is by the British computational scientist Peter Landing (https://zh.wikipedia.org/wiki/%E5%BD%BC%E5%BE%97%C2%B7%E5%85%B0%E4%B8% 81) The invention of a term, refers to a computer language added to a grammar, which has no effect on the function of the langu
React's JSX uses large, lowercase conventions to differentiate the classes and HTML tags of local components. Renders the local react component requires a label name that starts with an uppercase letter, which renders the HTML tag with the name of a label that begins with lowercase letters
Attention:
Because JSX is JavaScript, some identifiers class are like and for are not recommended as XML attribute names. As an alternative, the

Summary: In react, the data can be streamed from top to bottom, and whenever you use a component, you can see that the props property of the component is passed from top to bottom. However, in some cases, we do not want to pass through the parent component's props property one level down, and we want to get the value in the props of the parent component of the upper n level directly in a sub-component.
1. In general, through the props of the value of

Since React-router routes is components, creating nested routes is as simple as making one route a child of another in JS X.Make the nested component:class App extends React.component { render () { return( "/" component={home}> " About " component={about}> "Contact" component={ contact}> );} }Change the path:ConstLinks = () = 'Green'}} to="/">Home'Green'}} to="/about">About"Acti
The Redirect component in React-router does exactly what it sounds like. It allows us to redirect from the one route to another.Import React from ' React 'Import {hashhistory, Route, Redirect, Router, Link} from' React-router '; Const Home= () = Const Links= () = class App extends React.component {render () {return(
