arcgisJs之底图切换插件

arcgisJs之底图切换插件

底图切换插件在arcgis中有两种表现，以下：

1.两张底图切换

2.多张底图切换

1、两张地图切换

let basemapToggle = new BasemapToggle({
        view: this.view,
        nextBasemap: customBasemap
      })
this.view.ui.add(basemapToggle, 'top-right')

2、多张地图切换

var basemapGallery = new BasemapGallery({
        source: [ customBasemap, customBasemap1 ],
        view: this.view
      })
this.view.ui.add(basemapGallery, { position: 'top-right' })

注意：

1.切换插件上的图片显示不出来

缘由：未给底图对象设置图片路径  （thumbnailUrl）

import Basemapthumbnail from '../../assets/map_images/Basemapthumbnail.png'
import Basemapthumbnail1 from '../../assets/map_images/Basemapthumbnail1.png'

 let customBasemap = new Basemap({
        baseLayers: [tdtylayer1, layerProvince, tdtylayer2],
        title: '影像地图',
        id: 'myBasemap',
        thumbnailUrl: Basemapthumbnail
      })
let customBasemap1 = new Basemap({
        baseLayers: [tdtylayer, layerProvince, tdtylayer3],
        title: '矢量底图',
        id: 'myBasemap1',
        thumbnailUrl: Basemapthumbnail1
      })
