实现

1、安装leaflet-side-by-side插件

npm install leaflet-side-by-side --save

2、新建地图并添加两个图层

    this.map = L.map('map').setView([51.505, -0.09], 13);

    var osmLayer = L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
        attribution: '© '" DESIGNTIMESP=9853>OpenStreetMap<\/a'" DESIGNTIMESP=9840>http://osm.org/copyright">OpenStreetMap<\/a> contributors'
    }).addTo( this.map);

    var stamenLayer = L.tileLayer('https://stamen-tiles-{s}.a.ssl.fastly.net/watercolor/{z}/{x}/{y}.png', {
        attribution:
            'Map tiles by '" DESIGNTIMESP=9858>Stamen'" DESIGNTIMESP=9845>http://stamen.com">Stamen Design<\/a>, ' +
            ''" DESIGNTIMESP=9860>CC'" DESIGNTIMESP=9847>http://creativecommons.org/licenses/by/3.0">CC BY 3.0<\/a> — ' +
            'Map data {attribution.OpenStreetMap}',
        minZoom: 1,
        maxZoom: 16
    }).addTo(this.map)

L.control.sideBySide(stamenLayer, osmLayer).addTo(this.map);
