我在应用程序中使用react native router flux进行导航,我有容器文件夹和一个组件文件夹,我在其中创建了一个按钮组件。
这是我在容器文件夹中的Register.js文件,我还有一个只能呈现'hello world'的Verify.js文件
import React, { Component } from 'react';
import { View, Text, TextInput,StyleSheet} from 'react-native';
import {Actions} from 'react-native-router-flux';
import Button from '../../components/button/Button';
import styles from '../../styles/styles';
export default class Register extends Component{
constructor(){
super();
this.onPressButton = this.onPressButton.bind(this);
}
onPressButton(){
return ()=>Actions.verify();
}
render() {
return (
<View style={styles.global}>
<View style={styles.registerContainer}>
<Text style={styles.registerText}>Input your mobile number</Text>
</View>
<View style={styles.inputRow}>
<TextInput keyboardType={'numeric'} underlineColorAndroid={'transparent'} style={styles.zipCode}/>
<TextInput multiline={true} underlineColorAndroid={'transparent'} style={styles.number}/>
</View>
<Button text="REGISTER" onPressButton={this.onPressButton}/>
</View>
);
}
}
Button组件位于
之下import React,{Component,PropTypes} from 'react';
import {View,Text,TouchableHighlight,StyleSheet} from 'react-native';
export default class Button extends Component{
static propTypes={
text: PropTypes.string.isRequired,
onPressButton: PropTypes.func.isRequired
};
render(){
return(
<TouchableHighlight onPress={this.props.onPressButton}>
<View style={styles.btn}>
<Text style={styles.btn_text}>{this.props.text}</Text>
</View>
</TouchableHighlight>
);
}
}
另外,下面是我的删节应用程序文件,用于显示我想要路由到的场景。
<Scene key="root">
<Scene key="register" title="Register" hideNavBar component={Register} />
<Scene key="verify" title="Verify" hideNavBar component={Verify} />
/>
如何将导航功能作为道具传递给Button组件,以便onPressButton触发导航?
答案 0 :(得分:0)
哇!问这个问题,我真的觉得愚蠢。我不必要地过度思考问题。我甚至不需要做额外的功能。我需要做的就是将{Actions.verify}传递给onPressButton prop,并将proptype验证作为演示组件中的函数。第二种方法是在我的onPressButton函数中返回Actions.verify()而不是return()=&gt; Actions.verify()。
下面我完全删除了onPressButton函数,然后传递了{Actions.verify},其中verify是传递给我的组件场景的键。
import React, { Component } from 'react';
import { View, Text, TextInput,StyleSheet} from 'react-native';
import {Actions} from 'react-native-router-flux';
import Button from '../../components/button/Button';
import styles from '../../styles/styles';
export default class Register extends Component{
constructor(){
super();
}
render() {
return (
<View style={styles.global}>
<View style={styles.registerContainer}>
<Text style={styles.registerText}>Input your mobile number</Text>
</View>
<View style={styles.inputRow}>
<TextInput keyboardType={'numeric'} underlineColorAndroid={'transparent'} style={styles.zipCode}/>
<TextInput multiline={true} underlineColorAndroid={'transparent'} style={styles.number}/>
</View>
<Button text="REGISTER" onPressButton={Actions.verify}/>
</View>
);
}
}
在表述文件中,proptype验证仍然是相同的。
import React,{Component,PropTypes} from 'react';
import {View,Text,TouchableHighlight,StyleSheet} from 'react-native';
export default class Button extends Component{
static propTypes={
text: PropTypes.string.isRequired,
onPressButton: PropTypes.func.isRequired
};
render(){
return(
<TouchableHighlight onPress={this.props.onPressButton}>
<View style={styles.btn}>
<Text style={styles.btn_text}>{this.props.text}</Text>
</View>
</TouchableHighlight>
);
}
}
第二种方式
import React, { Component } from 'react';
import { View, Text, TextInput,StyleSheet} from 'react-native';
import {Actions} from 'react-native-router-flux';
import Button from '../../components/button/Button';
import styles from '../../styles/styles';
export default class Register extends Component{
constructor(){
super();
this.onPressButton = this.onPressButton.bind(this);
}
onPressButton(){
return Actions.verify();
}
render() {
return (
<View style={styles.global}>
<View style={styles.registerContainer}>
<Text style={styles.registerText}>Input your mobile number</Text>
</View>
<View style={styles.inputRow}>
<TextInput keyboardType={'numeric'} underlineColorAndroid={'transparent'} style={styles.zipCode}/>
<TextInput multiline={true} underlineColorAndroid={'transparent'} style={styles.number}/>
</View>
<Button text="REGISTER" onPressButton={this.onPressButton}/>
</View>
);
}
}
