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);}
}
