用AjaxMethod 方法实现动态加载地图

 

//前台函数

function BasicMap() {
    Coolite.AjaxMethods.ShowBasicMap({            //ShowBasicMap为后台地图处理AjaxMethod
    success: function(result) {
        var context='Map1';
        processCallbackResult(result, context);    

      //processCallbackResult是安装目录下ESRI.ADF.System.debug文件中的ESRI自带函数。处理后台返回的结果字符串，并将其展示在页面(包括地图）上。
    });

}

 

//后台函数主要实现动态加载地图

private static int i = 0;

 [AjaxMethod]
    public string ShowBasicMap()
    {
        MapResourceManager1.ResourceItems.Clear();
        MapResourceItem mapResourceItem = new MapResourceItem();

        GISResourceItemDefinition definition = new GISResourceItemDefinition();
        definition.DataSourceDefinition = "http://10.150.38.34/arcgis/services/";
        definition.DataSourceType = "ArcGIS Server Internet";
        definition.ResourceDefinition = "Layers@BaseMap";
        mapResourceItem.Definition = definition;

        ESRI.ArcGIS.ADF.Web.DisplaySettings displaysettings =
            new ESRI.ArcGIS.ADF.Web.DisplaySettings();
        displaysettings.Transparency = 0;
        displaysettings.Visible = true;
        mapResourceItem.Name = "basicmap"+i;
        mapResourceItem.DisplaySettings = displaysettings;
        int n = MapResourceManager1.ResourceItems.Count;
        MapResourceManager1.ResourceItems.Insert(n, mapResourceItem);
        mapResourceItem.InitializeResource();
         Map1.Refresh();
        i++;
        return Map1.CallbackResults.ToString();
        }
