How to send and display the value of a text input on another screen with native react?
0
I want to send the data of a text input that is stored in a variable to another screen and show the data that was saved in said variable
Try to pass the state of the variable by react-navigation but the problem is that I have 3 screens and I want to pass the data stored in the variable text from screen 1 to screen 3
class Screen1 extends Component {
constructor(props) {
super(props);
this.state = {
text: '',
percentage: ''
};
}
static navigationOptions = ({ navigation }) => {
const { params = {} } = navigation.state
var data = {
textData: params.text
}
return {

</TouchableOpacity>
</View>
),
}
};
// set by a default value in componentDidMount to make the next button disable initially
componentDidMount() {

this.props.navigation.setParams({ isDisable: true });
}

Pass the data up to the parent, the down to the other child. As in, pass a state-changing function as prop to the 1st child, and the state as prop to the 2nd child.

Pass the data up to the parent, the down to the other child. As in, pass a state-changing function as prop to the 1st child, and the state as prop to the 2nd child.

You can create a data object and you can send it with navigation to next UI. You can pass the data object from UI 1 to UI 2 and then you can send it UI 3 from UI 2.
In the first UI you can create data variable like,
var data = {
textData: text
}
Include the above code inside navigationOptions of your code.
Then in the navigation call include the data object as well.
onPress={() => navigation.navigate('2', {data})}
In the second UI assign the passed value to a variable inside the constructor.
constructor(props) {
super(props);
this.state = {
textData: this.props.navigation.state.params.data. textData,
}
}
Then when you are going to navigate to the third UI create a data variable and send it as previously done.
var data = {
textData: this.state.textData
}
Pass this variable with navigate.navigation and access it from third UI similar as in the second UI.

Hello, thank you very much for respodner I did what you suggested but I have a problem when I want to show the variable with the numeric content I get this error "Invariant Violation: Invariant Violation: Objects are not valid as a React child (found: object with keys { textData}). If you meant to render a collection of children, use an array instead. " and I do not know how to solve it :(
