react-google-maps：多个信息 windows 打开

Question

这可能是一个愚蠢的简单反应问题，但请耐心等待。我正在尝试运行带有多个标记的 react-google-maps 和信息 windows。这是代码：

const MapWithADirectionsRenderer = compose(
    withProps({
        googleMapURL: "https://maps.googleapis.com/maps/api/js?key=AIzaSyDf-yIqxErTkbWzKhLox7nAANnrfDIY190&libraries=geometry,drawing,places",
        loadingElement: <div style={{ height: `100%` }} />,
        containerElement: <div style={{ height: `800px` }} />,
        mapElement: <div style={{ height: `100%` }} />,
    }),
    withStateHandlers(() => ({
        isOpen: false,
    }), {
        onToggleOpen: ({ isOpen }) => () => ({
            isOpen: !isOpen,
        })
    }),
    withScriptjs,
    withGoogleMap,
    })
)(props =>
    <GoogleMap
        defaultZoom={13}
        defaultCenter={new google.maps.LatLng(42.357064, -71.062577)}
    >

        <Marker
            position={{ lat: 42.3381437, lng: -71.0475773 }}
            onClick={props.onToggleOpen}
        >
            {props.isOpen && <InfoWindow onCloseClick={props.onToggleOpen}>
                <h3>South Boston</h3>
            </InfoWindow>}
        </Marker>
        <Marker
            position={{ lat: 42.3875968, lng: -71.0994968 }}
            onClick={props.onToggleOpen}
        >
            {props.isOpen && <InfoWindow onCloseClick={props.onToggleOpen}>
                <h3>Somervil</h3>
            </InfoWindow>}
        </Marker>

        {props.directions && <DirectionsRenderer directions={props.directions} />}
    </GoogleMap>
);

当我单击其中一个标记时，所有标记的信息 windows 切换打开。我该如何切换打开我点击的标记的信息 window？

Answer 1

我建议引入一个组件：

class MarkerWithInfoWindow extends React.Component {

    constructor() {
        super();
        this.state = {
            isOpen: false
        }
        this.onToggleOpen = this.onToggleOpen.bind(this);
    }

    onToggleOpen() {
        this.setState({
            isOpen: !this.state.isOpen
        });
    }

    render() {
        return (<Marker
            position={this.props.position}
            onClick={this.onToggleOpen}>
            {this.state.isOpen && <InfoWindow onCloseClick={this.onToggleOpen}>
                <h3>{this.props.content}</h3>
            </InfoWindow>}
        </Marker>)
    }
}

通过MarkerWithInfoWindow状态控制每个标记window的信息：

 <GoogleMap
    defaultZoom={13}
    defaultCenter={new google.maps.LatLng(42.357064, -71.062577)}>

    <MarkerWithInfoWindow position={{ lat: 42.3381437, lng: -71.0475773 }} content="South Boston" />
    <MarkerWithInfoWindow position={{ lat: 42.3875968, lng: -71.0994968 }} content="Somervil" />

</GoogleMap>
