• 初始化 Map

<script>
        var map;
        require(["esri/map"], function (Map) {
            map = new Map("map", {
                basemap: "streets", //显示的地图样式 此处为地图，basemap: "satellite", //实景图
                center: [-80.94, 33.646], //地图加载后，初始位置
                zoom: 8, //放大级别，值越大放大的比例就越大
                slider: false,
                maxZoom: 18,//地图最大缩放级别
                minZoom: 1, //地图最小缩放级别
                logo: false  //不显示Esri的logo
            });

            //加载地图服务
            var myTiledMapServiceLayer = new esri.layers.ArcGISTiledMapServiceLayer(
                    "http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer");
            map.addLayer(myTiledMapServiceLayer);//添加到地图中
        });
    </script>

对于basemap，可以这样用：

basemap: basemap1, 
var basemap1 = {
            baseMapLayers: [
                {url: mapConfig.mapCompreShow}
            ],
            title: mapConfig.cityName,
            id: mapConfig.cityCode
        };

• Graphic实现的demo

  app.lineLayer = new esri.layers.GraphicsLayer({id: "lineLayer"}); //高亮显示的线路图层
  map.addLayer(app.lineLayer,1);
  app.lineLayer.add(new esri.Graphic(geo, new esri.symbol.CartographicLineSymbol(
                  esri.symbol.CartographicLineSymbol.STYLE_SOLID,
                  new dojo.Color(lineColor), lineWidth,
                  esri.symbol.CartographicLineSymbol.CAP_ROUND,
                  esri.symbol.CartographicLineSymbol.JOIN_MITER, 5
              ), "routeGraphic")); //线路添加到图层上

• 图层的显示顺序

  map.addLayer(app.startAndEndStationName,0);
  map.addLayer(app.lineLayer,1);
  map.addLayer(app.stationLayer,2);
  map.addLayer(busLayer,3);
  map.addLayer(app.startAndEndStationLayer,4);
