一、摘要

实现OAF的删除功能delete

二、案例

需求：实现删除功能

1. 建立Delete按钮的连接

2. 修改VO，增加按钮

3. 在SearchInvoiceCO.java中添加如下方法

4. 在InvoiceAM中添加如下方法

三、案例实现

1. 建立Delete按钮的连接

2. 修改VO，增加按钮

3. 在SearchInvoiceCO.java中添加如下方法

 1 public void processFormRequest(OAPageContext pageContext,OAWebBean webBean) {

 2

 3     super.processFormRequest(pageContext, webBean);

 4

 5     /**按下删除发票Button，触发AM中的AmDeleteInvoice方法**/

 6

 7     if ("delete".equals(pageContext.getParameter(EVENT_PARAM))) {

 8

 9         OAApplicationModule am = pageContext.getApplicationModule(webBean);

10

11         String InvoiceId = pageContext.getParameter("InvoiceId");

12

13         Serializable[] parameters = { InvoiceId };

14

15         am.invokeMethod("AmDeleteInvoice", parameters);

16

17     }

18

19 }

4. 在InvoiceAM中添加如下方法

 1 /**删除Invoice**/

 2

 3 public void AmDeleteInvoice(String InvoiceId) {

 4

 5     int InvoiceIdToDelete = Integer.parseInt(InvoiceId);

 6

 7     OAViewObject vo = (OAViewObject)getInvoiceSummaryVO1();

 8

 9     InvoiceSummaryVORowImpl row = null;

10

11     int fetchRowCount = vo.getFetchedRowCount();

12

13     System.out.print("bxj_count" + fetchRowCount);

14

15     RowSetIterator deleteIter = vo.createRowSetIterator("deleteIter");

16

17     if (fetchRowCount > 0) {

18

19         deleteIter.setRangeStart(0);

20

21         deleteIter.setRangeSize(fetchRowCount);

22

23         for (int i = 0; i < fetchRowCount; i++) {

24

25             row = (InvoiceSummaryVORowImpl)deleteIter.getRowAtRangeIndex(i);

26

27             Number primaryKey;

28

29             primaryKey = row.getInvoiceId();

30

31             if (primaryKey.compareTo(InvoiceIdToDelete) == 0) {

32

33                 row.remove();

34

35                 getTransaction().commit();

36

37                 break;

38

39             }

40

41         }

42

43     }

44

45     deleteIter.closeRowSetIterator();

46

47 }

Thanks and Regards
