React-navigation-props-helper NPM

react-navigation-props-helper

安装

yarn add react-navigation-props-helper 或 npm install --save react-navigation-props-helper

怎么使用？

NavigatorPush

1、跳转路由：NavigatorPush.navigate('TestPage', {userName:'userName', pwd:'pwd'}); //跳转路由

2、回退路由：NavigatorPush.goBack();

3、设置参数：NavigatorPush.setParameters({test:{key:'value'}}); //当前路由设置参数

import {NavigatorPush} from 'react-navigation-props-helper';

export default class App extends Component {
  render() {
    return (
      <View style={styles.container}>
        <RootView ref={navigatorRef => { NavigatorPush.setTopLevelNavigator(navigatorRef); }}/> //保存navigator的引用
        {/*<VideoPlayScreen url={'http://vodstztfqk4.vod.126.net/vodstztfqk4/3c901b47-0fc0-4490-9c2d-76b13465d4c4.mp4'}/>*/}
      </View>
    );
  }
}

withMappedNavigationProps

import React,{Component} from 'react';
import { View,StatusBar } from 'react-native';
import {observer} from 'mobx-react';
import { NavigatorPush,withMappedNavigationProps } from 'react-navigation-props-helper'

@withMappedNavigationProps
@observer
export default class TestPage extends Component {
    componentDidMount() {
        NavigatorPush.setParameters({test:{key:'value'}}); //当前路由设置参数
        console.log('componentDidMount');
    }
    render() {
        const {userName, pwd,test,navigation} = this.props;
        console.log('render:',userName, pwd,test,navigation);
        return(
            <View style={{flex:1}}>
                <StatusBar hidden={false} barStyle={'dark-content'} translucent={false} backgroundColor={'white'}/>
            </View>
        );
    }
}

routeInterceptor

拦截路由，比如某些页面需要登录才可以访问

NavigatorPush.routeInterceptor = (routeName, params) => {

    if (needLoginPage.indexOf(routeName) !== -1) {

        NavigatorPush.navigate('TestPage1',params);

        return false;
    }

    console.log('routeName',routeName);
    return true;
};
