有没有办法使用react-leaflet库使传单弹出窗口响应? [英] Is there a way to make a leaflet popup responsive using react-leaflet library?

问题描述

我一直在研究，我知道 leafletjs 具有插件反应叶.

react-leaflet 有很多第三方插件，但我不知道看不到对我有用的任何东西. 如果有人知道如何做或做过这样的事情，那么如果您能分享的话，那将是很酷的.我很难过这个.

谢谢.

解决方案

安装库，导入js，css获取地图参考，然后呈现标记:

import R from "leaflet-responsive-popup";
import "leaflet-responsive-popup/leaflet.responsive.popup.css";
...
  const position = [51.505, -0.09];
  const mapRef = useRef();

  const icon = L.icon({
    iconUrl: "https://unpkg.com/leaflet@1.6/dist/images/marker-icon.png",
    shadowUrl: "https://unpkg.com/leaflet@1.5.0/dist/images/marker-shadow.png"
  });

  useEffect(() => {
    const map = mapRef.current.leafletElement;
    const marker = L.marker([51.5, -0.09], { icon });
    const popup = R.responsivePopup({
      hasTip: true,
      autoPan: true,
      offset: [15, 20]
    }).setContent("A pretty CSS3 responsive popup.<br> Easily customizable.");

    marker.addTo(map).bindPopup(popup);
  }, []);

  return (
    <Map center={position} ref={mapRef} zoom={13} style={{ height: "100vh" }}>
      <TileLayer
        url="https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png"
        attribution='&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
      />
    </Map>
  );

修改 要使插件独立于外部包装器组件，您可以具有ResponsivePopup包装器文件:

const ResponsivePopup = () => {
  const { map } = useLeaflet();
  console.log(map);

  useEffect(() => {
    const marker = L.marker([51.5, -0.09], { icon });
    const popup = R.responsivePopup({
      hasTip: true,
      autoPan: true,
      offset: [15, 20]
    }).setContent("A pretty CSS3 responsive popup.<br> Easily customizable.");

    marker.addTo(map).bindPopup(popup);
  }, []);
  return null;
};

这一次，您将使用react-leaflet库提供的useLeaflet挂钩获取地图参考，然后对第一个解决方案采取类似的操作. 这次，您的Map或App组件将变成这样:

 <Map center={position} zoom={13} style={{ height: "100vh" }}>
      <TileLayer
        url="https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png"
        attribution='&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
      />
      // here use your custom wrapper for responsive popup
      <ResponsivePopup />
    </Map>

演示

I've been researching and I know leafletjs has the plugin https://github.com/yafred/leaflet-responsive-popup but I need a workaround for the library I'm using react-leaflet.

The react-leaflet has a lot of third-party plugins but I don't see anything that works for me. If someone knows how or has done something like this it would be cool if you could share it. I'm having a hard time with this.

Thanks.

解决方案

Install the library, import js, css get a map reference and then render the marker:

import R from "leaflet-responsive-popup";
import "leaflet-responsive-popup/leaflet.responsive.popup.css";
...
  const position = [51.505, -0.09];
  const mapRef = useRef();

  const icon = L.icon({
    iconUrl: "https://unpkg.com/leaflet@1.6/dist/images/marker-icon.png",
    shadowUrl: "https://unpkg.com/leaflet@1.5.0/dist/images/marker-shadow.png"
  });

  useEffect(() => {
    const map = mapRef.current.leafletElement;
    const marker = L.marker([51.5, -0.09], { icon });
    const popup = R.responsivePopup({
      hasTip: true,
      autoPan: true,
      offset: [15, 20]
    }).setContent("A pretty CSS3 responsive popup.<br> Easily customizable.");

    marker.addTo(map).bindPopup(popup);
  }, []);

  return (
    <Map center={position} ref={mapRef} zoom={13} style={{ height: "100vh" }}>
      <TileLayer
        url="https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png"
        attribution='&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
      />
    </Map>
  );

Edit To have the plugin independent in an external wrapper component you can have a ResponsivePopup wrapper file:

const ResponsivePopup = () => {
  const { map } = useLeaflet();
  console.log(map);

  useEffect(() => {
    const marker = L.marker([51.5, -0.09], { icon });
    const popup = R.responsivePopup({
      hasTip: true,
      autoPan: true,
      offset: [15, 20]
    }).setContent("A pretty CSS3 responsive popup.<br> Easily customizable.");

    marker.addTo(map).bindPopup(popup);
  }, []);
  return null;
};

in which this time you will get the map reference using the useLeaflet hook provided by react-leaflet library and then you act similarly with the first solution. This time your Map or App comp will become like this:

 <Map center={position} zoom={13} style={{ height: "100vh" }}>
      <TileLayer
        url="https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png"
        attribution='&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
      />
      // here use your custom wrapper for responsive popup
      <ResponsivePopup />
    </Map>
