                         var rows = $('#dwtjry').datagrid('getChecked');       //返回复选框选择的所有行                                                                                     
                        
                         for(var i=0; i<rows.length; i++){                        
                              var row = rows[i]; 
                              alert(row.xm);
                              var value1= $('#fzmc').datagrid("getRows");//返回当前页面所有行   
                             for(var i=0;i<value1.length;i++){                         
                              var da = value1[i];                                                                      
                                if(row.sfzh==da.sfzhm){
                                   alert('有重复提交');
                                     return;
                                    }  
                               }       
                                       var row = rows[i];                                                            
                                       $('#fzmc').datagrid('appendRow',{                                        
                                         xm:row.xm,
                                         xb:row.xb,
                                      sfzhm:row.sfzh,
                                       csny:row.csrq,
                                         dz:row.lxdz, 
                                         mz:row.mz,
                                       lxdh:row.yddh,
                                         bm:row.tjdw,
                                         gh:row.dwgh,
                                         gl:row.dwgl
                                      
                                       });                                    
                                    
                              }
 //                         }
                 }
