react-leaflet - 多个弹出窗口始终打开

Question

我想在地图加载时打开地图上的多个弹出窗口，我有这个答案的示例适用于一个弹出窗口：

弹出窗口始终在标记中打开

但是当我有多个弹出窗口时，只有一个在加载时打开，打开一个关闭另一个 - 在传单文档（http://leafletjs.com/reference-1.0.0.html#popup）中，它建议使用 addLayer 来避免这种情况但我不知道如何在 react-leaflet 中重新创建它：

const React = window.React;
const { Map, TileLayer, Marker, Popup, MapLayer, LayerGroup } = window.ReactLeaflet;

class SimpleExample extends React.Component {
  constructor() {
    super();
    this.state = {
      lat: 51.505,
      lng: -0.09,
      zoom: 13,
    };
  }

  render() {
    const position = [this.state.lat, this.state.lng];
    const position2 = [this.state.lat - 0.01, this.state.lng];
    return (
      <Map center={position} zoom={this.state.zoom}>
        <TileLayer
          attribution='&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
          url='http://{s}.tile.osm.org/{z}/{x}/{y}.png'
        />
        <ExtendedMarker position={position}>
          <Popup>
            <span>A pretty CSS3 popup. <br/> Easily customizable.</span>
          </Popup>
        </ExtendedMarker>

        <ExtendedMarker position={position2}>
         <Popup position={position2}>
            <span>A pretty CSS3 popup. <br/> Easily customizable.</span>
          </Popup>
        </ExtendedMarker>


      </Map>
    );
  }
}

// Create your own class, extending from the Marker class.
class ExtendedMarker extends Marker {
    // "Hijack" the component lifecycle.
  componentDidMount() {
    // Call the Marker class componentDidMount (to make sure everything behaves as normal)
    super.componentDidMount();

    // Access the marker element and open the popup.
    this.leafletElement.openPopup();
  }
}

window.ReactDOM.render(<SimpleExample />, document.getElementById('container'));

任何人在这个问题上绊倒，在更高版本的传单（例如：1.0.0+）中，您可以将其设置为显示多个弹出窗口的选项autoClose中的选项。Popupfalse

<Map center={position} zoom={this.state.zoom}>
    <TileLayer
      attribution='&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
      url='http://{s}.tile.osm.org/{z}/{x}/{y}.png'
    />
    <ExtendedMarker position={position}>
      <Popup autoClose={false}>
        <span>A pretty CSS3 popup. <br/> Easily customizable.</span>
      </Popup>
    </ExtendedMarker>

    <ExtendedMarker position={position2}>
     <Popup position={position2} autoClose={false}>
        <span>A pretty CSS3 popup. <br/> Easily customizable.</span>
      </Popup>
    </ExtendedMarker>


  </Map>
