                            ## 一、指南針

官方API：https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-Compass.html

~~~
// 先引入 esri/widgets/Compass 模塊
var compass = new Compass({view: mapView});
mapView.ui.add(compass, "top-left");
~~~

## 二、縮放按鈕

官方API：https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-Zoom.html

~~~
// 先引入 esri/widgets/Zoom 模塊
var zoom = new Zoom({
  view: mapView
});
mapView.ui.add(zoom, "top-right");
~~~

等等在esri/widgets里
