Question

我的应用中有3个页面有一组问题。每个页面大约有6个问题，用户需要回答这些问题，然后单击下一步。现在，当用户点击上一个时，他们应该能够在字段中看到键入的数据。我在我的代码中使用了cookie的概念，并根据此链接中的示例代码编写了getcookies和setcookies函数， http://www.the-art-of-web.com/javascript/setcookie/

这是我的代码，

 <script>
            // Original JavaScript code by Chirp Internet: www.chirp.com.au
            // Please acknowledge use of this code by including this header.

             var today = new Date();
             var expiry = new Date(today.getTime() + 30 * 24 * 3600 * 1000); // plus 30 days

             function setCookie(name, value)
  {
    document.cookie=name + "=" + escape(value) + "; path=/; expires=" + expiry.toGMTString();
  }
  function storeValues(form)  
  {
    setCookie("1.Your GPA from previous degree", form.field1.value);
    setCookie("2.Your GRE/GMAT score", form.field2.value);
    setCookie("2.Your GRE/GMAT score", form.field3.value);
    setCookie("3.Your TOEFL/IELTS score", form.field4.value);
    setCookie("3.Your TOEFL/IELTS score", form.field5.value);
    setCookie("4.Number of backlogs from your previous degree", form.field6.value);
    return true;
  }
  function getCookie(name)
  {
    var re = new RegExp(name + "=([^;]+)");
    var value = re.exec(document.cookie);
    return (value != null) ? unescape(value[1]) : null;
  }

</script>

` 在上面的脚本是带有大量下拉菜单和文本框的表单代码之后。第一页包含6个问题，但它们采用以下方式，

This is how the first page with the questions looks like, notice how the 2nd 3rd questions have 2 separate drop downs? I am not sure how to place them in terms of the ids in the functions

还有一个验证脚本，用于检查用户是否输入了所有必填字段，并将其添加到下一个按钮的onclick事件中，如下所示，onclick =“javascript：validate（）;”

我需要帮助才能找出我做错了什么。我知道我在需要通过id / name获取元素的区域中并不完全正确。请查看图像以了解我来自哪里，关于字段的ID /名称。任何帮助表示赞赏。

我也在这里发布表单代码，

 <form action = "POST" name="qform">
