How to pass values to other component in React-Nat

2019-01-23 04:22发布

问题:

My code is:

...
<Router>
 <Scene key="com1" component={Com1} initial/>
<Scene key="com2" component={Com2}/>
</Router>
...
com1.js
...
onPress={Actions.com2}

I changed com1 to com2.

But I need to pass values for the inputbox of Com1 to Com2.

How can I do that?

回答1:

You can pass data like this:

Actions.com2 ({text: 'Hello World'})

You can recover your data in com2 like this:

this.props.text

You can go to the next tutorial for more information:

回答2:

In addition to that, (and for those in the comments who said it didn't work) you may want to try below. When you pass the

Actions.com2({text : 'Hello World'});

Com2 should pass 'props'

const Com2 = (props) => {
   return ( <View ...
    {props.text}
   ... />
);

Pass data through an Input,

   import React, { Component } from 'react';
   import { Text, View, TextInput, TouchableOpacity } from 'react-native';
   import { Actions } from 'react-native-router-flux';

   export default class Com1 extends Component {
   state = { text: '' };
      render() {
       return (
          <View>
             <TextInput
                value={this.state.text}
                onChangeText={text => this.setState({ text })}
            />
    <TouchableOpacity onPress={this.onPressNext.bind(this)}>
   <Text>Get Data</Text>
    </TouchableOpacity>
    </View>
    );
}

onPressNext() {
    Actions.Com2({text: this.state.text });
}
}

To get value in the second Page

   export default class Com2 extends Component {

      render() {
         return (
        <View>
         <Text>
          {this.props.text}
         </Text>
       </View>
    );
  }
 }
