我的ArcGIS API for Javascript

为大家贴贴最基本的地图加载:

一. API 根据Dom树上节点的 ID 确定 Map 的显示位置;

二. setBasemap 方法可得到一些ArcGIS制作好的底图,例如: "streets" , "satellite" , "hybrid", "topo", "gray", "oceans", "national-geographic", "osm";

三. setEXtent 方法可设置地图的显示区域;

<!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>

补充:
  1.地图初始化时即可完成各种属性的设置,new Map(divId, options?);

     例如:var map = new Map(“mapDiv”,{ basemap: "osm" , extent: bounds});

  2.欲加载已发布的服务,只需新建图层并加入map 即可;

     例如: var layer = new esri.layers.ArcGISDynamicMapServiceLayer( url ); map.addLayer(layer);

效果:
