Hi all,

trying to complete a simple form using JQuery, JQuery Validation Plugin, JQuery Form Plugin, Thomas Vestergaards MailChimp4Umbraco Plugin and Jonas Eriksson guidelines for Razor, I ended up with the following working code:

@{
  string ajaxPostPath = "/AjaxRazor?path=" + VirtualPath;
  string mailChimpListID = @Parameter.MailChimpListID; 
}

@(IsPost ? SendSignupForm() : RenderSignupForm(@ajaxPostPath, @mailChimpListID))

@helper RenderSignupForm(string ajaxPostPath, string mailChimpListID)
{
  <script type="text/javascript">
    function hideForm() { $("#form").hide(); }
    function disableButton() { $(".submit").attr('disabled', 'disabled'); }
    
    $(function() {
      var loader = $("#loader").hide();

      $(document).ajaxStart(function() {
        hideForm();
        loader.show();
      }).ajaxStop(function() {
        loader.hide();
      }).ajaxError(function(a, b, e) {
        throw e;
      });

      var v = $("#form").validate({
        submitHandler: function(form) {
          $(form).ajaxSubmit({
            target: "#results",
            url: "@ajaxPostPath",
            data: { list_id: "@mailChimpListID"},
            beforeSubmit: disableButton
          });
        }
      });
    });
  </script>
  
  <form method="post" action="#" id="form">
    <input type="text" name="email" id="email" class="required email" />
    <br />
    <input type="submit" class="submit" value="Subscribe" />
  </form>
  <div id="loader" style="top: 5px; margin-right: 5px"><img src="/images/loading.gif" alt="loading..." width="20px" height="20px" />Loading...</div>
  <div id="results"></div>
}

@helper SendSignupForm()
{
  string retval = String.Empty;
  bool showResult;
  
  try
  {
    var postedEmail = Request["email"];
    var mailChimpListID = Request["list_id"];
    
    if (IsAjax)
    {
      // System.Threading.Thread.Sleep(5000);
      showResult = true;
      retval = "Invalid e-mail address";
      if (IsValidEmail(postedEmail))
      {
        showResult = true;
        MailChimpCommunicator communicator = new MailChimpCommunicator(ConfigurationManager.AppSettings["UmbracoMailChimp.APIKey"]);
        MailChimpResponse response = communicator.AddSubscriber(mailChimpListID, postedEmail, Request.UserHostAddress, String.Empty, String.Empty);
        
        if (response.IsSuccess)
        {
          retval = "Subscription completed";
        }
        else
        {
          string errorCode = String.Format(" ({0})", response.ErrorCode);
          retval = String.Format("Error {0}", errorCode);
        }
      }
    }
    else
    {
      showResult = false;
      retval = "Javascript disabled!";
    }
  }
  catch (Exception ex)
  {
    retval = ex.Message;
  }
  finally
  {
   <div>@retval</div>
  }
}

@functions
{
  private static bool IsValidEmail(string email)
  {
    bool retval = false;
    if (!String.IsNullOrEmpty(email))
    {
      retval = Regex.IsMatch(email, @"^(?("")(""[^""]+?""@)|(([0-9a-z]((\.(?!\.))|[-!#\$%&'\*\+/=\?\^`\{\}\|~\w])*)(?<=[0-9a-z])@))" + @"(?(\[)(\[(\d{1,3}\.){3}\d{1,3}\])|(([0-9a-z][-\w]*[0-9a-z]*\.)+[a-z0-9]{2,17}))$", RegexOptions.IgnoreCase);
    }
    return retval;
  }
}

As you can see my programming skills are really poor, but this is the least concerned about right now!!

My real issue is that this cshtml file is rendered via a macro with a "MailChimpListID" parameter, which I cannot access via my "SendSignupForm" helper method directly (i.e. using the Parameter directive).

The only way I managed to get this working is using the form's "Data" property. Using this method though, leaves my List's ID unprotected, which I don't think is a good think...

So, is there any way to get this value directly from my helper method?

Thanks in advance,
