我試圖改變被點擊的按鈕的道具：如果點擊超過 3 次，我想禁用它。
這是我的代碼：
import React, { useState } from 'react';
import { Button, Text, View } from 'react-native';
const App = () => {
const [pressedCount, setPressedCount] = useState(0);
return (
<View style={{ flex: 1, justifyContent: 'center' }}>
<Text style={{ margin: 16 }}>
{pressedCount > 0
? `The button was pressed ${pressedCount} times!`
: 'The button isn\'t pressed yet'
}
</Text>
<Button
title='Press me'
onPress={() => if (pressedCount>=3){Button.setState.({disabled:true})} else{setPressedCount(pressedCount 1)}}
/>
</View>
);
};
export default App;
我試過 if (pressedCount>=3){Button.props.disabled=true} else{setPressedCount(pressedCount 1)}} 但它是一樣的。
有關如何正確執行此操作的任何建議？
uj5u.com熱心網友回復：
<Button
title="Press me"
onPress={() => setPressedCount((prevState) => prevState 1)}
disabled={pressedCount > 3}
/>;
