This is do by defining a ref .Notice: ' Ref ' works in class component, not in statless component.If we don ' t add "ref", three slider would mutate the same state, they won ' t has isolated scope.If we want they behave differently, then we need to use

To make more composable react components, you can define common APIs for similar component types. import React from ‘react‘;import ReactDOM from ‘react-dom‘;export default class App extends React.Component{ constructor(){ super(); this.state = {

REACT provides a life cycle hook function for each component TI to respond to different moments-the period of creation and the period of destruction.Instantiation Period:When you first use a groupItem Class:This method is not called when Getdefaultprops is not the first time it is calledGetinitialstateComponentwillmountRenderComponentdidamountExistence Period:ComponentwillreceivepropsShouldcomponentupdateRenderComponentdidupdateDestruction PeriodCompo

Modal components Not much to say, next let's start implementing a react modal component.

Ok! On the Android phone, when we use the physical return key, will be a one-time program exit, this is a very bad experience, so we need to use the physical return key component of Rn: Backandroid, the principle isAnalyze the route and then pop () like this!Ok! Let's start with the routing stack! , a bit of computer technology based on the students should learn the stack, which is the stack is the back into first out, that is, RN inside the push (into the stack), pop (out of the stack)!Good!!1:
