推荐答案
更新您的单选按钮名称以使用某些索引，即
Update your radio button name to use some index i.e.
在顶部：声明索引变量。
At the top side: declare the index variable.
<% int qNum = 0; %>
在页面中间，使用 radio 字段命名。
In middle of page, use the index variable in radio field naming.
<input type="radio" name="a<%=qNum%>" value="QA" />
<input type="radio" name="a<%=qNum%>" value="QB" />
<input type="radio" name="a<%=qNum%>" value="QC" />
<input type="radio" name="a<%=qNum%>" value="QD" />
在页面底部，检索索引参数并将索引增加一。
In the bottom of the page, retrieve the index parameter and increase the index by one.
<% g=request.getParameter("a"+qNum);
qNum++;
%>
