詳解js界面跳轉與值傳遞

這篇文章主要爲你們詳細介紹了js界面跳轉與值傳遞的相關代碼,具備必定的參考價值，感興趣的小夥伴們能夠參考一下

本文實例實現的功能以下：註冊頁(Register.js)，點擊註冊，跳到註冊結果頁(RegisterResult.js)，並將註冊的手機號傳遞過去，顯示xx註冊成功。 

'use strict' import React, { Component } from 'react'; import { AppRegistry,Navigator,BackAndroid} from 'react-native';   var Register = require('./study/Register'); let RegisterResult = require('./study/RegisterResult'); var NaviModule = React.createClass({     //告知Navigator模塊，咱們但願在視圖切換時，用什麼效果   configureScene:function(route){     return Navigator.SceneConfigs.FadeAndroid;   },     //告知Navigator模塊，咱們但願如何掛接當前視圖   renderScene:function(router,navigator){     this._navigator = navigator;     switch(router.name){       case "register":         return <Register navigator = {navigator}/>       case "registerResult":         return <RegisterResult telephoneNumber = {router.telephoneNumber} navigator = {navigator}/>       }   },     //React的生命週期函數---組件被掛接時調用   componentDidMount:function(){     var navigator = this._navigator;     BackAndroid.addEventListener('NaviModuleListener',()=>{       if (navigator && navigator.getCurrentRoutes().length > 1) {         navigator.pop();         return true;       }       return false;     });   },     //React的生命週期函數---組件被移除時調用   componentWillUnmount: function(){     BackAndroid.removeEventListener('NaiModuleListener');   },     render:function(){     return (       <Navigator         initialRoute = {{name:'register'}}         configureScene = {this.configureScene}         renderScene = {this.renderScene} />       );   }   });   AppRegistry.registerComponent('FirstDemo', () => NaviModule);
