说明：本篇博文介绍的是ArcGIS API for JavaScript中的 Bookmarks(书签) ，书签的作用是，把地图放大到一个地方 添加书签，书签名称可以和地图名称一直，单击标签 地图会定位到刚才选中的地方。大致就是这个意思！
有关ArcGIS API for JavaScriptde的引用文件的部署 请参考我的前面的博客

其中的代码
map = new esri.Map("map", { basemap: "topo", center: [-100, 40], zoom: 4 });
也可以替换为以下形式
map = new esri.Map("map", { center: [-100, 40], zoom: 4 });
MyTiledMapServiceLayer = new esri.layers.ArcGISTiledMapServiceLayer
("http://localhost/arcgis/rest/services/DZDT2012/MapServer");
map.addLayer(MyTiledMapServiceLayer);
