我是一个反应原生的新手,我试图在屏幕之间导航......我按照一个简单的教程,不幸的是,当我按下“To Stats页面”TouchableHighlight我得到错误:undefined不是一个对象(评估'这个' .props.navigator.push')。附上主屏幕的屏幕截图和错误(单击TO STATS PAGE),下面是代码(我包含了我认为错误发生的评论):
import React, { Component } from 'react';
import {AppRegistry,StyleSheet,TouchableHighlight,Navigator,Text,View} from 'react-native';
class Navi extends Component {
render() {
return (
<Navigator
initialRoute={{ name: 'main' }}
renderScene={this.renderScene.bind(this)}
/>
);
}
renderScene(route, navigator) {
if(route.name == 'main') {
return <Main navigator={navigator} />
}
if(route.name == 'stats') {
return <Stats navigator={navigator} />
}
}
}
export default class Main extends Component {
// THINK THE ERROR IS HERE
navigate(routeName) {
this.props.navigator.push({
name: routeName
});
}
render() {
return (
<View style={styles.container}>
<Text style={styles.welcome}>
Main
</Text>
<TouchableHighlight onPress={this.navigate.bind(this, "stats")}>
<Text>TO STATS PAGE</Text>
</TouchableHighlight>
</View>
);
}
}
class Stats extends Component {
render() {
return (
<View style={styles.container}>
<Text style={styles.welcome}>
Stats
</Text>
<TouchableHighlight onPress={()=>{this.props.navigator.pop()}}>
<Text>BACK</Text>
</TouchableHighlight>
</View>
);
}
}
const styles = StyleSheet.create({
container: {marginTop:20,flex: 1,justifyContent: 'center',alignItems: 'center',
backgroundColor: '#F5FCFF',},
welcome: {fontSize: 20,textAlign: 'center',margin: 10,},
});
AppRegistry.registerComponent('navi', () => Navi);
答案 0 :(得分:-1)
伙计们,我认为这是最好的!修复是Navi应该导出不是主...
