React 迭代当前 this
React iteration current this
我有一个简单的数据结构，其中列出了一些信息。问题是当我单击图标时，它会打开这两个内容。我没有找到如何打开当前 div.
的解决方案
class HotSpots extends React.Component {
constructor(props, context) {
super(props, context);
this.handleClick = this.handleClick.bind(this);
this.state = {
isOpen: false,
icon: 'fa-plus'
}
}
handleClick(event) {
console.log(this.state.isOpen, 'clicked');
this.setState({
isOpen: !this.state.isOpen,
icon: this.state.icon === 'fa-plus' ? 'fa-remove' : 'fa-plus'
})
}
render() {
//console.log(DATA.module.hotSpots.popups);
let items = DATA.module
.hotSpots
.popups.map(n =>
<div data-open={n.openByDefault}
data-coordx={n.config.coords[0]}
data-coordy={n.config.coords[1]}
data-enable-mobile-chords={n.config.useMobileCoords>
<a style={{
marginLeft: n.config.coords[0],
marginRight: n.config.coords[1]
}}
onClick={this.handleClick}>
<i className={`fa ${this.state.icon}`}></i>
</a>
<section data-is-open={this.state.isOpen} className="hotspot-detail">
<h2>{n.headline}</h2>
<p>{n.bodyCopy}</p>
</section>
</div>
);
return (
<section className="hotspots">
{console.log('status' + this.state.isOpen)}
<div>{items}</div>
</section>
)
}
}
class App extends React.Component {
constructor(props) {
super(props)
}
render() {
return <div name={this.props.name}
data-src-phone-highres={this.props.srcPhoneHighRes}
data-src-desktop={this.props.srcDesktop}
data-src-tablet-highres={this.props.srcTabletHighres}
data-src-phone={this.props.phone}
data-src-tablet={this.props.srcTablet}
data-src-desktop-highres={this.props.srcDesktopHighres}>
<HotSpots />
</div>
}
}
React.render( <App name={DATA.moduleName}
srcPhoneHighRes={DATA.images.desktop.externalUrl}
/>, app);

提前致谢
这是因为您将相同的状态 (isOpen) 关联到所有内容。
要显示此内容，请将您的笔修改为：
handleClick(event) {
this.setState({
parentClass :event.currentTarget.className,
isOpen: !this.state.isOpen,
icon: this.state.icon === 'fa-plus' ? 'fa-remove' : 'fa-plus'
})
}
render() {
let items = DATA.module
.hotSpots
.popups.map((n,i) =>
<div data-open={n.openByDefault}
data-coordx={n.config.coords[0]}
data-coordy={n.config.coords[1]}
data-enable-mobile-chords={n.config.useMobileCoords}>
<a style={{
marginLeft: n.config.coords[0],
marginRight: n.config.coords[1]
}}
onClick={this.handleClick} className={'parent'+i}>
<i className={`fa ${this.state.icon}`}></i>
</a>
<section data-is-open={this.state.isOpen && (this.state.parentClass===("parent"+i)) } className="hotspot-detail">
<h2>{n.headline}</h2>
<p>{n.bodyCopy}</p>
</section>
</div>
);
return (
<section className="hotspots">
{console.log('status' + this.state.isOpen)}
<div>{items}</div>
</section>
)
}
}

希望对您有所帮助
正如@XtremeCoder 所建议的。您没有使用唯一的 key 标识符来跟踪您的事件。因此，在您的 React 组件中，按以下方式在点击处理程序中传递密钥 onClick={this.handleClick.bind(this, i, n) 然后包含一个新状态 i，它可以捕获当前 element 已点击。
this.state = {
i: 0,
isOpen: false,
}
}
handleClick(i,n) {
this.setState({
i: i,
isOpen: !this.state.isOpen,
})
现在您可以在状态更改时检查 boolean 以显示 content 并更改 icon
//for icon
<i className={`fa ${(this.state.isOpen && this.state.i==i ? 'fa-close' : 'fa-plus')}` }></i>
//for content
<section data-is-open={this.state.isOpen && this.state.i==i} className="hotspot-detail">
这是功能齐全的代码
