反应按钮活动样式

Question

我是 React 和 UI 开发的新手，请耐心等待。 我有一个按钮列表，我正在尝试在按钮处于活动状态时设置不同的图像图标，当我单击另一个按钮时，第二个按钮应该处于活动状态，第一个按钮处于非活动状态，依此类推。

这是我的代码：

export class ABC extends Component {
configFile = require('../../resources/stubs/config.json')
constructor(props) {
super(props);
this.state = {
cSelected: [],
isHidden: true,
level: this.configFile.Level,
amount: this.configFile.amount,
des1: this.configFile.desc1,
des2: this.configFile.desc2,
des3: this.configFile.desc3,
}
this.onRadioBtnClick = this.onRadioBtnClick.bind(this);
};
onRadioBtnClick(cSelected, aSelected, d1, d2, d3) {
this.setState({
cSelected,
aSelected,
d1,
d2,
d3
});
}

render(){
return (
<div>
<ButtonGroup>
<Button className="circleIcon" 
onClick={() => this.onRadioBtnClick(this.state.level, this.state.amount, this.state.des1, this.state.des2, this.state.des3, )} 
active={this.state.cSelected === 1}><img src={incirclePurple}  
alt="profile-tab-icon" />|<span className="numberCircle">1</span></Button>
<Button className="circleIcon" onClick={() => this.onRadioBtnClick("Circle2", "$1,000-$2,499", this.state.des1, this.state.des2, this.state.des3)} active={this.state.cSelected === 2}><img src={incirclePurple}  alt="profile-tab-icon" />|<span className="numberCircle">2</span></Button>
<Button className="circleIcon" onClick={() => this.onRadioBtnClick("Circle3", "$2,500-$4,999", this.state.des1, this.state.des2, this.state.des3)} active={this.state.cSelected === 3}><img src={incirclePurple}  alt="profile-tab-icon" />|<span className="numberCircle">3</span></Button>
<Button className="circleIcon" onClick={() => this.onRadioBtnClick("Circle4", "$5,000-$9,999", this.state.des1, this.state.des2, this.state.des3)} active={this.state.cSelected === 4}><img src={incirclePurple}  alt="profile-tab-icon" />|<span className="numberCircle">4</span></Button>
<Button className="circleIcon" onClick={() => this.onRadioBtnClick("Circle5", "$10,000-$34,999", this.state.des1, this.state.des2, this.state.des3)} active={this.state.cSelected === 5}><img src={incirclePurple}  alt="profile-tab-icon" />|<span className="numberCircle">5</span></Button>
<Button className="circleIcon" onClick={() => this.onRadioBtnClick("Circle6", "$35,000-$74,999", this.state.des1, this.state.des2, this.state.des3)} active={this.state.cSelected === 6}><img src={incirclePurple}  alt="profile-tab-icon" />|<span className="numberCircle">6</span></Button>
<Button className="circleIcon" onClick={() => this.onRadioBtnClick("President's Circle", ">$74,999", this.state.des1, this.state.des2, this.state.des3)} active={this.state.cSelected === 7}><img src={incirclePurple}  alt="profile-tab-icon" />|<span className="numberCircle">7</span></Button>
<Button className="circleIcon" onClick={() => this.onRadioBtnClick("Chairman's Circle", ">$74,999", this.state.des1, this.state.des2, this.state.des3)} active={this.state.cSelected === 8}><img src={incirclePurple}  alt="profile-tab-icon" />|<span className="numberCircle">8</span></Button>
</ButtonGroup>   
<div>
<p>{this.state.cSelected}{this.state.aSelected}</p>
<ul>
<li>{this.state.d1}</li>
<li>{this.state.d2}</li>
<li>{this.state.d3}</li>
</ul>
</div> 
</div>) 
}
}

Answer 1

您可以为每个按钮提供一个唯一的name道具，并创建一个activeButton状态，该状态将采用激活按钮名称的值：

handleActiveButton(e) {
e.preventDefault();
const activeName = e.target.name;
this.setState({ activeName });
}

然后在className按钮的道具中，你可以做一些类似className={ this.state.activeName === 'button1' ? 'active' : '' }

其中button1是按钮的名称，active是用于显示图像图标的 css 类。

Answer 2

我明白了！！

通过 id 填充了活动名称的值

谢谢！！
