这是我的JSP代码：<form action="baocunshijian" method="post">
<tr>
<td><input type="checkbox" value="<%=user.getUsernumberid()%>" name="box1" /></td>
<td><%=user.getUsernumber() %></td>
<td><%=user.getName() %></td>
<td><input type="text" value="<%=user.getDatetime() %>" name="riqi" /></td>
<td><input type="text" value="<%=user.getGotime() %>" name="riqi1" onfocus="WdatePicker({skin:'whyGreen',dateFmt:'HH:mm:ss'})" class="Wdate" /></td>
<td><input type="text" value="<%=user.getOuttime() %>" name="riqi2" onfocus="WdatePicker({skin:'whyGreen',dateFmt:'HH:mm:ss'})" class="Wdate" /></td>
<td><input type="text" value="<%=user.getOpentime() %>" name="riqi3" onfocus="WdatePicker({skin:'whyGreen',dateFmt:'HH:mm:ss'})" class="Wdate" /></td>
</tr>
这是Action的代码：User user = new User();
baocunUsertime update = new baocunUsertime();
Boolean isSuccessed = false;
HttpServletRequest request = ServletActionContext.getRequest();
String a = request.getParameter("box1");
System.out.println(a);
user.setUsernumberid(Integer.parseInt(a));
user.setDatetime(new String(request.getParameter("riqi")));
user.setGotime(new String(request.getParameter("riqi1")));
user.setOuttime(new String(request.getParameter("riqi2")));
user.setOpentime(new String(request.getParameter("riqi3")));
这是取值的打印结果：
