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

public void processFormRequest(OAPageContext pageContext,OAWebBean webBean) {

    super.processFormRequest(pageContext, webBean);

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

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

        OAApplicationModule am = pageContext.getApplicationModule(webBean);

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

        Serializable[] parameters = { InvoiceId };

        am.invokeMethod("AmDeleteInvoice", parameters);

    }

}

 

 

4. 在InvoiceAM中添加如下方法

/**删除Invoice**/

public void AmDeleteInvoice(String InvoiceId) {

    int InvoiceIdToDelete = Integer.parseInt(InvoiceId);

    OAViewObject vo = (OAViewObject)getInvoiceSummaryVO1();

    InvoiceSummaryVORowImpl row = null;

    int fetchRowCount = vo.getFetchedRowCount();

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

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

    if (fetchRowCount > 0) {

        deleteIter.setRangeStart(0);

        deleteIter.setRangeSize(fetchRowCount);

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

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

            Number primaryKey;

            primaryKey = row.getInvoiceId();

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

                row.remove();

                getTransaction().commit();

                break;

            }

        }

    }

    deleteIter.closeRowSetIterator();

}
