并排反应传单 [英] React leaflet side-by-side

问题描述

我想并排显示两个图块层，就像传单的插件并排显示(

解决方案

只需创建一个组件并在导入插件后使用 useEffect 中的原生传单代码即可.

 导入并排放置的小叶"；...const Map =()=>{useEffect(()=> {const map = L.map("map").setView([51.505，-0.09]，13);const osmLayer = L.tileLayer("http://{s} .tile.osm.org/{z}/{x}/{y} .png"，{归因:'& copy;< a href ="http://osm.org/copyright"> OpenStreetMap</a>贡献者的}).addTo(map);var stamenLayer = L.tileLayer("https://stamen-tiles- {s} .a.ssl.fastly.net/watercolor/{z}/{x}/{y} .png"，{归因:'通过< a href ="http://stamen.com"> Stamen Design</a>绘制地图图块，'+'< a href ="http://creativecommons.org/licenses/by/3.0"> CC BY 3.0</a>& mdash;'+地图数据{attribution.OpenStreetMap}"，minZoom:1maxZoom:16}).addTo(map);L.control.sideBySide(stamenLayer，osmLayer).addTo(map);}，[]);返回< div id ="map"/> ;;}; 

演示

I wanted to show two tile layers side by side, like the plugin side-by-side for leaflet (https://github.com/digidem/leaflet-side-by-side).

However, I am not sure how to do this with react. Is there a way to use the above mentioned plugin in react? Do you have any other suggestions on how to accomplish this functionality?

解决方案

Just create a component and use the native leaflet code inside a useEffect after importing the plugin.

import "leaflet-side-by-side";
...

const Map = () => {
  useEffect(() => {
    const map = L.map("map").setView([51.505, -0.09], 13);

    const osmLayer = L.tileLayer("http://{s}.tile.osm.org/{z}/{x}/{y}.png", {
      attribution:
        '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
    }).addTo(map);

    var stamenLayer = L.tileLayer(
      "https://stamen-tiles-{s}.a.ssl.fastly.net/watercolor/{z}/{x}/{y}.png",
      {
        attribution:
          'Map tiles by <a href="http://stamen.com">Stamen Design</a>, ' +
          '<a href="http://creativecommons.org/licenses/by/3.0">CC BY 3.0</a> &mdash; ' +
          "Map data {attribution.OpenStreetMap}",
        minZoom: 1,
        maxZoom: 16
      }
    ).addTo(map);

    L.control.sideBySide(stamenLayer, osmLayer).addTo(map);
  }, []);

  return <div id="map" />;
};
