In this article, we’ll look at how to bind onPress with an argument in React Native.
How to bind onPress with an argument in React Native?
To bind onPress with an argument in React Native, we can create a function that returns the onPress
handler function.
For instance, we write:
import * as React from 'react';
import { Button, View } from 'react-native';
import Constants from 'expo-constants';
import { Card } from 'react-native-paper';
export default function App() {
const onPress = (arg) => () => {
console.log(arg);
};
return (
<View>
<Button title="button" onPress={onPress('hello')} />
</View>
);
}
to add a Button
with the onPress
prop set to the function that we get after we call onPress
with 'hello'
.
We define onPress
to return a function that logs the arg
that we passed into the outer function.
Therefore, when we press the button, we see 'hello'
logged.
Conclusion
To bind onPress with an argument in React Native, we can create a function that returns the onPress
handler function.
