詳解js界面跳轉(zhuǎn)與值傳遞
本文實例實現(xiàn)的功能如下:注冊頁(Register.js),點擊注冊,跳到注冊結果頁(RegisterResult.js),并將注冊的手機號傳遞過去,顯示xx注冊成功。
index.Android.js
'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,我們希望在視圖切換時,用什么效果
configureScene:function(route){
return Navigator.SceneConfigs.FadeAndroid;
},
//告知Navigator模塊,我們希望如何掛接當前視圖
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的生命周期函數(shù)---組件被掛接時調(diào)用
componentDidMount:function(){
var navigator = this._navigator;
BackAndroid.addEventListener('NaviModuleListener',()=>{
if (navigator && navigator.getCurrentRoutes().length > 1) {
navigator.pop();
return true;
}
return false;
});
},
//React的生命周期函數(shù)---組件被移除時調(diào)用
componentWillUnmount: function(){
BackAndroid.removeEventListener('NaviModuleListener');
},
render:function(){
return (
<Navigator
initialRoute = {{name:'register'}}
configureScene = {this.configureScene}
renderScene = {this.renderScene} />
);
}
});
AppRegistry.registerComponent('FirstDemo', () => NaviModule);
