React和Ionic是两个流行的前端开发框架,用于构建跨平台的移动应用程序。在Ionic中,IonicSegmentButton是一个UI组件,用于创建可切换的按钮选项卡。要设置active IonicSegmentButton,可以使用React/Ionic提供的以下方法:
import React, { useState } from 'react';
import { IonSegment, IonSegmentButton } from '@ionic/react';
const MyComponent = () => {
const [activeButton, setActiveButton] = useState(0);
const handleButtonClick = (index) => {
setActiveButton(index);
};
return (
<IonSegment value={activeButton} onIonChange={handleButtonClick}>
<IonSegmentButton value={0}>
Button 1
</IonSegmentButton>
<IonSegmentButton value={1}>
Button 2
</IonSegmentButton>
<IonSegmentButton value={2}>
Button 3
</IonSegmentButton>
</IonSegment>
);
};
export default MyComponent;
import React from 'react';
import { IonSegment, IonSegmentButton } from '@ionic/react';
const MyComponent = () => {
return (
<IonSegment>
<IonSegmentButton checked={true}>
Button 1
</IonSegmentButton>
<IonSegmentButton>
Button 2
</IonSegmentButton>
<IonSegmentButton>
Button 3
</IonSegmentButton>
</IonSegment>
);
};
export default MyComponent;
以上是使用React/Ionic设置active IonicSegmentButton的两种方法。根据具体的需求和项目结构,选择适合的方法来实现所需的功能。
