后臺(tái)action代碼

復(fù)制代碼代碼如下:

 
public class StationAction extends BaseAction { 

private List<Map<String, Object>> provinceList; 
public void setProvinceList(List<Map<String, Object>> provinceList) { 
this.provinceList = provinceList; 
} 

public List<Map<String, Object>> getProvinceList() { 
return provinceList; 
} 
public String getProvinceJSON(){ 
String sql="SELECT PK_ID PROVINCEID,NAME PROVINCENAME FROM T_DICT_DISTRICT A WHERE A.DISTRICT_LEVEL=20"; 
provinceList= stationService.findBySQL(sql); 
return "json_getProvinceList"; 
} 
} 

strtus xml配置

復(fù)制代碼代碼如下:

 
<result name="json_getProvinceList" type="json" > 
<param name="root">provinceList</param> 
</result> 

加載靜態(tài)數(shù)據(jù)的下拉選擇框

復(fù)制代碼代碼如下:

 
var dataType=[['0','8列'],['1','38列'],['2','21列']]; 
var dataTypeStore = new Ext.data.SimpleStore({ 
fields: ['dataTypeID', 'dataTypeName'], 
data : data 
});
