一、需求背景

在业务单据列表中，需要对列数据某个字段值进行批量修改；例如需要对以下列表数据中的“备注”的值进行批量修改。

二、实现方案

添加一个动态表单，提供给用户输入修改值。用户选择列表行之后，然后点击“批量修改备注”，弹出动态表单；用户输入值之后点击确认，把值写回各个单据。

1、列表插件，弹出动弹表单

public class DemoListBatchModify extends AbstractListPlugin {
@Override
public void registerListener(EventObject e) {
           // TODO Auto-generated method stub
           super.registerListener(e);
}
@Override
public void beforeItemClick(BeforeItemClickEvent evt) {
           if (evt.getItemKey().equals("kded_batchmodify")) {
                    BillList billlistap = this.getView().getControl("billlistap");
                    ListSelectedRowCollection selectedRows = billlistap.getSelectedRows();
                    // 校验
                    if (selectedRows.size() <= 0) {
                             evt.setCancel(true);
                             this.getView().showMessage("请先选择要修改的单据行！");
                    }
           }
           super.beforeItemClick(evt);
}
 
@Override
public void itemClick(ItemClickEvent evt) {
           if (evt.getItemKey().equals("kded_batchmodify")) {
                    // 弹出动态表单
                    FormShowParameter showParameter = new FormShowParameter();
                    showParameter.setFormId("kded_listbatchmodify");
                    showParameter.setCloseCallBack(new CloseCallBack(this, "batchmodify"));
                    showParameter.getOpenStyle().setShowType(ShowType.Modal);
                    this.getView().showForm(showParameter);
           }
           super.itemClick(evt);
}

2、创建动态表单

点击“确认修改”，返回数据

public class BatchModifyFormPlugin extends AbstractFormPlugin {
         @Override
         public void registerListener(EventObject e) {
                   Button btnok = this.getView().getControl("btnok");
                   btnok.addClickListener(this);
                   super.registerListener(e);
         }
 
         @Override
         public void beforeClick(BeforeClickEvent evt) {
                   super.beforeClick(evt);
         }
 
         @Override
         public void click(EventObject evt) {
                   if (evt.getSource() instanceof Button) {
                            Button source = (Button) evt.getSource();
                            String key = source.getKey();
                            if (key.equals("btnok")) {
                                     Object modifyinfo = this.getModel().getValue("kded_modifyinfo");
                                     // 返回数据
                                     this.getView().returnDataToParent(modifyinfo);
                                     this.getView().close();
                            }
                   }
                   super.click(evt);
         }
}

3、列表插件接受返回值，修改已选列表数据的“备注”值

@Override
public void closedCallBack(ClosedCallBackEvent closedCallBackEvent) {
           String actionId = closedCallBackEvent.getActionId();
           if (actionId.equals("batchmodify")) {
                    Object returnData = closedCallBackEvent.getReturnData();
                    BillList billlistap = this.getView().getControl("billlistap");
                    ListSelectedRowCollection selectedRows = billlistap.getSelectedRows();
                    String billFormId = billlistap.getBillFormId();
                    ArrayList<Object> ids = new ArrayList<>();
                    for (ListSelectedRow listSelectedRow : selectedRows) {
                             Object pk = listSelectedRow.getPrimaryKeyValue();
                             ids.add(pk);
                    }
                    // 查询数据
                    QFilter idQFilter = new QFilter("id", QCP.in, ids);
                    DynamicObject[] load = BusinessDataServiceHelper.load(billFormId, "kded_infor",
                                       new QFilter[] { idQFilter });
                    for (DynamicObject dynamicObject : load) {
                             dynamicObject.set("kded_infor", returnData);
                    }
                    // 更新数据
                    SaveServiceHelper.update(load);
//                          //刷新数据
                    this.getView().invokeOperation("refresh");
                   
           }
           super.closedCallBack(closedCallBackEvent);
}
