react-leaflet - 多个弹出窗口始终打开

Question

我希望在 map 上有多个弹出窗口，这些弹出窗口在 map 加载时打开，我从这个答案中得到了适用于一个弹出窗口的示例:

Popup always open in the marker

但是当我有多个弹出窗口时，只有一个在加载时打开，打开一个会关闭另一个 - 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，但我不知道如何重新创建它在 react 传单中:

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'));

任何在这个问题上遇到困难的人，在更高版本的传单中(例如:1.0.0+)有一个选项 autoClose在Popup的选项中，您可以将其设置为false以显示多个弹出窗口。

<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>
