我有很多命中,一旦按下命中,我想将它们添加到数组中。但是,据我观察,该数组看起来像是获得了命中的名称,即值。该值在半秒内消失了。
我尝试过诸如构建构造函数之类的方法,并执行诸如
onClick={e => this.handleSelect(e)}
value={hit.name}
onClick={this.handleSelect.bind(this)}
value={hit.name}
onClick={this.handleSelect.bind(this)}
defaultValue={hit.name}
等等
export default class Tagsearch extends Component {
constructor(props) {
super(props);
this.state = {
dropDownOpen:false,
text:"",
tags:[]
};
this.handleRemoveItem = this.handleRemoveItem.bind(this);
this.handleSelect = this.handleSelect.bind(this);
this.handleTextChange = this.handleTextChange.bind(this);
}
handleSelect = (e) => {
this.setState(
{ tags:[...this.state.tags, e.target.value]
});
}
render() {
const HitComponent = ({ hit }) => {
return (
<div className="infos">
<button
className="d-inline-flex p-2"
onClick={e => this.handleSelect(e)}
value={hit.name}
>
<Highlight attribute="name" hit={hit} />
</button>
</div>
);
}
const MyHits = connectHits(({ hits }) => {
const hs = hits.map(hit => <HitComponent key={hit.objectID} hit={hit}/>);
return <div id="hits">{hs}</div>;
})
return (
<InstantSearch
appId="JZR96HCCHL"
apiKey="b6fb26478563473aa77c0930824eb913"
indexName="tags"
>
<CustomSearchBox />
{result}
</InstantSearch>
)
}
}
基本上,我想要的是在按下相应的按钮后将命中组件的名称传递给 handleSelect 方法。
