选择时您可以传递 item on 方法,单击时您可以设置 item 值。请检查以下代码。
演示: https ://codesandbox.io/s/stackoverflowmodal-19i36
this.state = {
result: null,
show: false,
selectedItem:null,
helpId: null
};
//
showModal = (selectedItem) => {
this.setState({
show: !this.state.show,
selectedItem
});
};
//
class Actions extends React.PureComponent {
constructor() {
super();
this.state = {
result: null,
show: false,
selectedItem: null,
helpId: null
};
this.setSearchTopStories = this.setSearchTopStories.bind(this);
this.showModal = this.showModal.bind(this);
this.handleClickFromParent = this.handleClickFromParent.bind(this);
this.onClose = this.onClose.bind(this);
}
onClose = e => {
this.setState({
show: false
});
};
handleClickFromParent = e => {
this.setState({
show: !this.state.show
});
};
showModal = selectedItem => {
this.setState({
show: !this.state.show,
selectedItem
});
};
setSearchTopStories(result) {
this.setState({ result });
}
componentDidMount() {
fetch(`${PATH_BASE}`)
.then(response => response.json())
.then(result => this.setSearchTopStories(result))
.catch(error => error);
}
render() {
const { searchTerm, result, selectedItem } = this.state;
return (
<div>
{result && result.length
? result.map((item, index) => (
<div>
<div onClick={() => this.showModal(item)}>{item.name}</div>
</div>
))
: null}
{selectedItem && (
<Modal
id={index}
handleClickFromParent={this.handleClickFromParent}
item={[selectedItem]}
show={this.state.show}
onClose={this.onClose}
>
YOLO
</Modal>
)}
</div>
);
}
}
export default Actions;
