為大家貼貼最基本的地圖加載：
一. API 根據Dom樹上節點的 ID 確定 Map 的顯示位置;
二. setBasemap 方法可得到一些ArcGIS制作好的底圖，例如： "streets" , "satellite" , "hybrid", "topo", "gray", "oceans", "national-geographic", "osm";
三. setEXtent 方法可設置地圖的顯示區域;
<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <title> Demo </title> <link rel="stylesheet" href="http://js.arcgis.com/3.10/js/esri/css/esri.css"> <script type="text/javascript" src="http://js.arcgis.com/3.9/"></script> <style> html,body,#mapDiv { width: 100%; height: 100%; } </style> <script> require([ "esri/map", "esri/geometry/Extent" ], function(){ var map = new esri.Map("mapDiv"); map.setBasemap("osm"); var bounds = new esri.geometry.Extent({ "xmin":118.363523,"ymin":29.219302,"xmax":119.508848,"ymax":30.073848, "spatialReference":{"wkid":4326}}); map.setExtent(bounds); }); </script> </head> <body> <div id="mapDiv"></div> </body> </html>
補充：
1.地圖初始化時即可完成各種屬性的設置，new Map(divId, options?);
例如：var map = new Map(“mapDiv”,{ basemap: "osm" , extent: bounds});
2.欲加載已發布的服務，只需新建圖層並加入map 即可;
例如: var layer = new esri.layers.ArcGISDynamicMapServiceLayer( url ); map.addLayer(layer);
效果：
