1、editForm.form.reset();
var sore=Ext.getCmp('csCustContDet_linkManGrid_pbop').getStore()
sore.removeAll();
2、  var regionResult=Main.jsonRpcClient._call('areaService.getAreaList','1');
      if(regionResult){
        regionStore.loadData(regionResult.list); 
      }
   var provinceResult=Main.jsonRpcClient._call('areaService.getAreaList','2');
      if(provinceResult){
        provinceStore.loadData(provinceResult.list); 
      }
   var cityResult=Main.jsonRpcClient._call('areaService.getAreaList','3');
      if(cityResult){
        cityStore.loadData(cityResult.list); 
      }
var districtResult=Main.jsonRpcClient._call('areaService.getAreaList','4');
      if(districtResult){
        districtStore.loadData(districtResult.list); 
      }
