asp.net 做简单的动态有奖调查-优快云博客

本文详细介绍了一个调查问卷系统的后台数据处理和前端展示逻辑。系统能够根据不同类型的题目（单选、多选、填空）动态生成相应的表单元素，并通过JavaScript收集用户答案。此外，还提供了根据用户选择显示调查结果的功能。

后台从数据库里读出数据并按格式现实：显示问题和答案的时候标签格式固定有问题编号选项序号

前台js存储答案：

<script language="javascript" type="text/javascript">
    function InfoGet()

        {
            if(Element[i].type=="radio")
            {
