React-Google-Maps Redux-Marker单击上的InfowDindow

Question

我试图对我的页面产生与React-Google-Map演示相同的效果。我使用了React-Google-Maps。问题是我正在获取带有标记信息的数据，我不知道该如何处理会显示/隐藏InfowDindow的点击。可能是有状态的原因，我不知道如何使标记数组中每个标记的变量" iSshown"。这是我的代码：

const GettingStartedGoogleMap = withGoogleMap(props => (
  <GoogleMap
    ref={props.onMapLoad}
    defaultZoom={16}
    defaultCenter={props.defCenter}
    onClick={props.onMapClick}
  >
    {props.markers.map((marker,i) => (
      <Marker
        key={i}
        position={marker.location}
        time={marker.time}
        onClick={() => props.onMarkerClick(marker)}
        // HERE I TRIED SOMETHING LIKE marker.isShown=true; but it is NOT WORKING
      >
        {
          <InfoWindow>
             <div className="marker-text">{marker.time}</div>
          </InfoWindow>
        }
      </Marker>
    ))}
  </GoogleMap>
));
class GettingStartedExample extends Component {
  componentDidMount(){
    this.props.fetchMarkers();
  }
  state = {
     markers: this.props.markers,
   };
  handleMapLoad = this.handleMapLoad.bind(this);
  handleMarkerClick = this.handleMarkerClick.bind(this);
  handleMapLoad(map) {
    this._mapComponent = map;
    if (map) {
      console.log(map.getZoom());
    }
  }
  handleMarkerClick(targetMarker) {
    /*
     * All you modify is data, and the view is driven by data.
     * This is so called data-driven-development. (And yes, it's now in
     * web front end and even with google maps API.)
     */
    const nextMarkers = this.state.markers.filter(marker => marker !== targetMarker);
    console.log(targetMarker.showInfo)
    this.setState({
      markers: nextMarkers,
    });
  }
  render() {
    return (
      <div className='container map-container'>
        <GettingStartedGoogleMap
          containerElement={
            <div style={{ height: `100%` }} />
          }
          mapElement={
            <div style={{ height: `100%` }} />
          }
          onMapLoad={this.handleMapLoad}
          markers={this.props.markers}
          onMarkerClick={this.handleMarkerClick}
          defCenter={{lat: 50.07074, lng: 19.915718}}
        />
      </div>
    );
  }
}
GettingStartedExample.propTypes={
  markers: React.PropTypes.array.isRequired,
  fetchMarkers: React.PropTypes.func.isRequired
}
function mapStateToProps(state){
  return{
    markers:state.markers
  }
}
export default connect(mapStateToProps,{fetchMarkers})(GettingStartedExample);

目前看起来像这样：

Infowindow的标记

在我的最终效果上，我想在最新的标记上放上infowdindow，然后句柄单击，允许您在所有标记上显示/隐藏Infowdindows。

如何在每个标记上实现/隐藏infowdindow？

非常感谢您的任何帮助！

您可以尝试此

我在nextProps中获得标记数组，因此将其设置为状态

您可以使用自己的标记数组

import React from 'react'
import { Link } from 'react-router'
import { withGoogleMap, GoogleMap, Marker, InfoWindow } from 'react-google-maps'
const num10 = 10
const GettingStartedGoogleMap = withGoogleMap((props) => (
  <GoogleMap
    ref={props.onMapLoad}
    defaultZoom={10}
    center={props.center}
    onClick={props.onMapClick}
  >
    {props.markers.map((marker, index) => (
      <Marker
        key={index}
        position={marker.position}
        onClick={() => props.onMarkerClick(marker)}
        {...marker}
        //onRightClick={() => props.onMarkerRightClick(index)}
      >
        {marker.showInfo && (
          <InfoWindow onCloseClick={() => props.onMarkerClose(marker)}>
            <div className="">
              myinfowindow
            </div>
          </InfoWindow>
        )}
        </Marker>
    ))}
  </GoogleMap>
))
class GoogleMaps extends React.Component {
  constructor(props) {
    super(props)
    this.state = {
      center: {
        lat: 33.6890603,

        let newArray = []

try this: (props.showInfoIndex == index ) instead of ( props.isOpen )
{props.nhatro.map((nhatro, index) =>
        <Marker
          key={index}
          options={{icon: 'https://i.imgur.com/9G5JOp8.png'}}
          position={nhatro}
          onClick={()=>{ props.showInfo(index)} }
        >
          { (props.showInfoIndex == index ) && 
          <InfoWindow  onCloseClick={props.onToggleOpen}>
            <div>
              <div>nhà trọ cho thuê</div>
              <div >1.500.000đ</div>
            </div>
          </InfoWindow>}
        </Marker>
    )}
use showInfo fnc to setState :
showInfo(a){
 setState({showInfoIndex: a })
}

嘿，您的信息窗口是子组件，如果您想打开InfowDindow，只需使Info窗口与标记类等效，并根据需要制作任何子组件

尝试以下操作：

<Map
                                    google={this.props.google}
                                    style={style}
                                    initialCenter={{
                                        lat: lat,
                                        lng: lng
                                    }}
                                    zoom={zoom}
                                    onClick={this.onMapClicked}
                                >
                                {marker && marker.map((marker, index) => (
                                    <Marker
                                        key={index}
                                        onClick={this.onMarkerClick}
                                        title={marker.place_id}
                                        name={marker.place_name}
                                        position={{ lat: marker.place_latitude, lng: marker.place_longitude }} >
                                        {
                                            <div></div>
                                        }
                                    </Marker>
                                ))}
                                    <InfoWindow
                                        marker={this.state.activeMarker}
                                        visible={this.state.showingInfoWindow}>
                                        <div>
                                            <h3>{this.state.selectedPlace.name}</h3>
                                        </div>
                                    </InfoWindow>
                                </Map>
