HTML JSP代码创建问题

我有一个提交按钮，创建于 - 基本上当单击此按钮时，我希望在提交按钮所在的位置下方出现一个组框......有什么建议吗？

我试图从这次点击中获取请求，但这对我没有帮助。我想逻辑应该是这样的：

<form>
   <input type="checkbox" name="group" value="Yes" />Yes
   <input type="checkbox" name="group" value="No" /> No
   <input type="submit" value="submit" />
</form>
<%
   String[] select = request.getParameterValues("group");
  /* Add code creation here */
%>

你能想到什么建议或例子吗？

非常感谢， U。

I have a submit button, created from - basically when this is clicked I want a groupbox to appear below where the submit button is....any suggestions?

I've tried to get the request given of from this click however it doesn't help me.
I thought the logic would be similar to this:

<form>
   <input type="checkbox" name="group" value="Yes" />Yes
   <input type="checkbox" name="group" value="No" /> No
   <input type="submit" value="submit" />
</form>
<%
   String[] select = request.getParameterValues("group");
  /* Add code creation here */
%>

Any suggestions or examples you can think of?

Thanks greatly,
U.

首先用单选按钮替换复选框。现在可以同时检查Yes和No。这毫无意义。

<form>
   <input type="radio" name="group" value="Yes" /> Yes
   <input type="radio" name="group" value="No" /> No
   <input type="submit" value="submit" />
</form>

然后，使用 JSTL 标签根据参数有条件地显示内容/或 EL 中的其他作用域变量。

<c:if test="${param.group == 'Yes'}">
    <p>Write here HTML code which you'd like to show when 'Yes' is chosen.</p>
</c:if>
<c:if test="${param.group == 'No'}">
    <p>Write here HTML code which you'd like to show when 'No' is chosen.</p>
</c:if>

First replace the checkboxes by radio buttons. Right now it's possible to check both Yes and No. This makes no sense.

<form>
   <input type="radio" name="group" value="Yes" /> Yes
   <input type="radio" name="group" value="No" /> No
   <input type="submit" value="submit" />
</form>

Then, use JSTL <c:if> tag to conditionally display content depending on parameters and/or other scoped variables in EL.

<c:if test="${param.group == 'Yes'}">
    <p>Write here HTML code which you'd like to show when 'Yes' is chosen.</p>
</c:if>
<c:if test="${param.group == 'No'}">
    <p>Write here HTML code which you'd like to show when 'No' is chosen.</p>
</c:if>
