中心点跳转示例

// ES5引入方式
const { Map } = zondy
const { MapView } = zondy.leaflet
// ES6引入方式
import { Map } from "@mapgis/webclient-common"
import { MapView } from "@mapgis/webclient-leaflet-plugin"
// 初始化图层管理容器
map = new .Map();
// 初始化地图视图对象
mapView = new MapView({
  // 视图id
  viewId: "view-id",
  // 图层管理容器
  map: map
});
// 视点跳转
mapView.flyTo({
  // 跳转中心点
  center: [{x}, {y}],
  // 地图层级
  zoom: {zoom}
});

按范围跳转示例

// ES5引入方式
const { Map } = zondy
const { Extent } = zondy.geometry
const { MapView } = zondy.leaflet
// ES6引入方式
import { Map, Extent } from "@mapgis/webclient-common"
import { MapView } from "@mapgis/webclient-leaflet-plugin"
// 初始化图层管理容器
map = new Map();
// 初始化地图视图对象
mapView = new MapView({
  // 视图id
  viewId: "view-id",
  // 图层管理容器
  map: map
});
mapView.flyTo({
  // 范围几何
  extent: new Extent({
     "xmin":10,
     "xmax":210,
     "ymin":0,
     "ymax":100,
  })
});

按范围跳转示例-拿到图层信息后跳转

// ES5引入方式
const { IGSMapImageLayer } = zondy.layer
// ES6引入方式
import { IGSMapImageLayer } from "@mapgis/webclient-common"
const igsMapImageLayer = new IGSMapImageLayer({
  url: 'http://192.168.82.89:8089/igs/rest/services/Map/Hubei4326/MapServer'
});
map.add(igsMapImageLayer);
// 图层加载完毕
igsMapImageLayer.on('layer-view-created', function (result) {
  console.log("加载完毕:", result.layer)
  //视点跳转
  mapView.flyTo({
    extent: result.layer.extent
  });
})
