ArcGIS API for JavaScript 3.x與4.x 去除ESRI logo的方法

寫在前面

arcgis for js中加載地圖，默認會有圖下的Logo。3.x與4.x去除方式分別如下:

arcgis api for js 3.x版本去除logo

map = new esri.Map("map", { extend:initExtend,logo:false });

arcgis api for js 4.x版本去除logo

var view = new MapView({ ...  });
// 去除logo                        
view.ui._removeComponents(["attribution"]);
