如何在action类中识别两个不同的jsp页面按钮？如何编写条件，基于jsp页面查看按钮和查看所有按钮？

Question

文件名为 ScanorAttach.jsp - 此文件包含查看全部按钮。注意-我正在导入 results.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>

results.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'}">
                                            <img src="${path}/images/edit.png" title="Edit" onclick="editDocument('${result.id}');"/>
                                            <img src="${path}/images/trash.png" title="Delete" onclick="removeDocument('${result.documentName}', '${result.id}');"/>
                                        </c:when>
                                        <c:otherwise>
                                            <c:if test="${not (roleDuty.viewAccountingScanAttach
                                                              && (scanForm.screenName eq 'INVOICE' || scanForm.screenName eq 'AR BATCH'))}">
                                                  <img src="${path}/images/icons/scanner.png" title="Scan" onclick="showComment('${result.documentName}', 'Scan');"/>
                                                  <img src="${path}/images/icons/attach.png" title="Attach" onclick="showComment('${result.documentName}', 'Attach');"/>
                                            </c:if>
                                        <img src="${path}/images/icons/preview.png" title="View" onclick="showDocuments('${result.documentName}')"/> 
                                            <c:if test="${result.uploadCount > 0}">
                                                <span class="red-90" style="vertical-align: super">
                                                    (${result.uploadCount})
                                                </span>
                                            </c:if>
                                        </c:otherwise>
                                    </c:choose>
                                </td>
                            </tr>

                        </c:forEach>

例如，我有 2 个文件预订和照片。如果我单击查看（预订）按钮，则查看特定文档（仅限预订）。如果我单击查看所有按钮，则应显示所有文件（预订和照片）。 文件名 -documents.jsp

<div class="results-container">
<table width="100%" cellpadding="0" cellspacing="1" class="display-table" id="filelist">
    <thead>
        <tr>

    </thead>
    <tbody>
        <c:set var="zebra" value="odd"/>
        <c:forEach var="result" items="${scanForm.results}" varStatus="status">

                <td>${str:splitter(result.comments, 75, '<br/>')}</td>
                <td>

                    <c:choose>
                        <c:when test="${roleDuty.deleteAttachedDocuments eq 'true' && not empty results3}">
                           <img src="${path}/images/trash.png"
                                 title="Delete" onclick="deleteDocumentSop('${result.id}', '${result.fileName}', '${result.documentName}')"/>
                        </c:when>
                        <c:otherwise>

                    </c:choose>
                </td>
            </tr>

动作类名-ScanAction.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());
        scanForm.setResults(results);
    }
    request.setAttribute("results3", request.getSession().getAttribute("results3"));
    return mapping.findForward(DOCUMENTS);
}

public ActionForward deleteDocument(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
    ScanForm scanForm = (ScanForm) form;
    DocumentStoreLogDAO documentDAO = new DocumentStoreLogDAO();
    DocumentStoreLog document = documentDAO.findById(scanForm.getId());
    File file = new File(document.getFileLocation(), document.getFileName());
    if (file.exists()) {
        file.delete();
    }
    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);
}

列表无法正常工作。Booking 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，删除后只显示一个文件。在我的项目中，它显示了所有文件（也包括照片文件）。我想你已经理解了。提前谢谢你

Answer 1

if(request.getParameter("viewAll.x") != null){ <br>

}else if(request.getParameter("view.x") != null){ <br>

}

在动作类中，您可以检查用户是否单击了每个按钮。
