20150716 Created By BaoXinjian

一、摘要

---

Oracle dialogPage是OAF提示框的一种用法，具体应用例如在删除数据时，提示用户进行确认是否可以删除

 

二、实现方法

---

在CO中添加如下方法

public void processFormRequest(OAPageContext pageContext,OAWebBean webBean) {
   super.processFormRequest(pageContext, webBean);

   //跳出提示框
   if ("Delete".equals(pageContext.getParameter(EVENT_PARAM))){
    //提示框信息初始化
    OAException mainMessage = new OAException("Delete The Employee Information，Please Confirm?");  
    OADialogPage dialogPage = new OADialogPage(OAException.WARNING, mainMessage, null, "", "");       
    dialogPage.setOkButtonItemName("DeleteYesButton");
    dialogPage.setOkButtonToPost(true);
    dialogPage.setNoButtonToPost(true);
    dialogPage.setPostToCallingPage(true);
    dialogPage.setOkButtonLabel("Delete");
    dialogPage.setNoButtonLabel("Cancel");
    //传递参数给提示框
    Hashtable formParams = new java.util.Hashtable(1);
    formParams.put("empNum", employeeNumber);
    formParams.put("empName", employeeName);
    dialogPage.setFormParameters(formParams);
    pageContext.redirectToDialogPage(dialogPage);
  } 
  //提示框提示确认后，进行删除资料，资料删除后提示数据已被删除
  else if (pageContext.getParameter("DeleteYesButton") != null) {
    String employeeNumber = pageContext.getParameter("empNum");
    String employeeName = pageContext.getParameter("empName");
    Serializable[] parameters = { employeeNumber };
    OAApplicationModule am = pageContext.getApplicationModule(webBean);     
    am.invokeMethod("deleteEmployee", parameters);
    //资料删除后提示信息
    MessageToken[] tokens = { new MessageToken("EMP_NAME", employeeName) };
    OAException message = new OAException("AK", "FWK_TBX_T_EMP_DELETE_CONFIRM", tokens, OAException.CONFIRMATION, null);
    pageContext.putDialogMessage(message);
  }
}

 

三、运行测试

Step1. 点击需删除记录的资料

Step2.  提示框显示是否需要删除
