ArcGIS JavaScript API 添加點

function ShowStationOnMap(stations) {

     // 清除圖中的元素    

　　map.graphics.clear();

      // 設置顯示中心點及坐標

　　var location = new esri.geometry.Point(stations[0].longtitude, stations[0].latitude, map.spatialReference)    

　　map.centerAndZoom(location, 8);

      // 逐個添加元素

      for (var s = 0; s < stations.length; s++) {        

　　     var symbol = new esri.symbol.PictureMarkerSymbol(stations[s].imageUrl, 18, 18);        

　　     var pt = new esri.geometry.Point(stations[s].longtitude, stations[s].latitude, map.spatialReference)

           // 每個元素的屬性值     

　　     var attr = { "stationName": stations[s].stationName, "sId": stations[s].sId, "countryName": stations[s].countryName, "projectName": stations[s].projectName, 　            　　       "buildYear": stations[s].buildYear };   

           // 點擊該元素時的信息窗  

　　     var infoTemplate = new esri.InfoTemplate("${stationName}", "站點編號: ${sId}<br/>所屬項目: ${projectName}  <br/>所屬區縣: ${countryName}

                          <br/>建成年份:${buildYear}<div><a href='javascript:ShowDetailStationPanel(" + stations[s].sId + ")'>查看詳情</a> </div>");        

           var graphic = new esri.Graphic(pt, symbol, attr, infoTemplate);        

           map.graphics.add(graphic);    

     }

}

當在外部點擊一個點時在地圖上顯示該數據的信息窗 這里用的是 map.infoWindow 和 infoTemplate 有點區別

 var pt = new esri.geometry.Point(data.record.longtitude, data.record.latitude, map.spatialReference)        

 var attr = { "stationName": data.record.stationName, "sId": data.record.sId, "countryName": data.record.countryName, "projectName": data.record.projectName,

                   "buildYear": data.record.buildYear };

 var infoTemplate = new esri.InfoTemplate("${stationName}", "站點編號: ${sId}<br/>所屬項目: ${projectName}  <br/>所屬區縣: ${projectName} <br/>建成年份:

                   ${buildYear}<div><a href='javascript:ShowDetailStationPanel(" + data.record.sId + ")'>查看詳情</a> </div>");        

 var symbol = new esri.symbol.PictureMarkerSymbol(data.record.imageUrl, 18, 18);        

 var graphic = new esri.Graphic(pt, symbol, attr, infoTemplate);        

 map.infoWindow.setContent(graphic.getContent()); 

 map.infoWindow.setTitle(data.record.stationName);        

 map.infoWindow.show(pt, map.getInfoWindowAnchor(pt));
