如何在操作类中识别两个不同的 JSP 页面按钮?如何基于 JSP 页面视图按钮和查看全部按钮编写条件

文件名是ScanorAttach.jsp- 此文件包含查看全部按钮。 注意 - 我正在导入结果.jsp。

<c:if test="${not empty scanForm.results1 || not empty scanForm.results2}">
<input type="button" value="View All"  class="button float-right" onclick="showDocuments('')"/>
</c:if>
<tr>
<td>
 <c:import url="/jsp/common/scan/results.jsp"/></td>
</tr>

结果.jsp - 此文件包含"查看"按钮

 <c:forEach var="result" items="${scanForm.results1}" varStatus="status">
                            <tr class="${zebra}">
                                <td>${result.documentName}</td>
                                <c:if test="${empty scanForm.documentId && loginuser.role.roleDesc eq 'Admin'}">
                                    <td>${result.screenName}</td>
                                </c:if>
                                <td>
                                    <c:choose>
                                        <c:when test="${empty scanForm.documentId && loginuser.role.roleDesc eq 'Admin'}">

例如，我有 2 份文件预订和照片。 如果我单击查看（预订）按钮，则会查看特定文档（仅限预订）。 如果我单击"查看全部"按钮，则应显示所有文件（预订和照片）。文件名 -文档.jsp

操作类名称 - 扫描操作.jsp

 public ActionForward showDocuments(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
    ScanForm scanForm = (ScanForm) form;
    if (CommonUtils.isNotEmpty(scanForm.getScreenName())) {
        List<ResultModel> results = new ScanDAO().getDocuments(scanForm.getScreenName(), scanForm.getDocumentName(), scanForm.getDocumentId());

    }
    request.setAttribute("message", document.getFileName() + " is deleted successfully");
    documentDAO.delete(document);
  //   scanForm.setDocumentName(""); here i want to write condition and also how to differentiate view and View All Button. 
    return showDocuments(mapping, form, request, response);
}

该列表无法正常工作。预订包含 2 个文件。照片包含 3 个文件.如果我在预订中删除 1 个文件，删除后仅显示一个文件。在我的项目中，它显示了所有文件（照片文件也），我想你被理解了。提前谢谢你
