我是jstl的新手,我需要帮助在jsp上获取url-string参数,该参数还包含从数据库中检索的迭代对象列表中的EL标记。有人可以告诉我如何修复下面的代码,以便下面的代码行填充一个实际的数字,我要求${param.spid}:
<a href="create-course-summary?spid="${param.spid}>add</a>
以下是背景资料:
我正在使用以下url模式调用servlet:
view-course-summaries?spid=1
这在servlet中调用以下doGet
方法:
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
String spidString = req.getParameter("spid");
Long spid = new Long(spidString);
List<CourseSummary> coursesummaries = new CourseSummaryDAO().findAllCS(spid);
req.setAttribute("coursesummaries", coursesummaries);
jsp.forward(req, resp);
}
并返回以下jsp:
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ include file="admintop.inc" %>
<table>
<tr>
<td>Name of School (Course Provider):</td>
<td>will go here</td>
</tr>
<tr><td colspan=2>
<a href="create-course-summary?spid="${param.spid}>add</a>
</td>
</tr>
<tr>
<td colspan=2>
<table>
<tr>
<th>Type</th>
<th>Number</th>
<th>id</th>
</tr>
<c:forEach varStatus="loopCounter" items="${coursesummaries}" var="coursesummary">
<tr>
<td>
<c:out value="${coursesummary.coursetype}" />
</td>
<td>
<c:out value="${coursesummary.numunits}" />
</td>
<td>
<c:out value="${coursesummary.id}" />
</td>
</tr>
</c:forEach>
</table>
</td>
</tr>
</table>
<%@ include file="adminbottom.inc" %>
答案 0 :(得分:21)
试试这个
<a href='create-course-summary?spid=${param["spid"]}'>add</a>
