     If Not Empty(@Email) Then

My current code is not working means its not posting any records to DE. Can i get any help on this?

I don't have an immediate answer for your script issue, but I have some words of advice and guidance which might save you in the long-term.

You intended script will post to a SFMC cloud page upon every change url: "https://pub.s7.exacttarget.com/123",

This will become very costly (unless you have an agreement with Salesforce we're unaware of); as Salesforce charge by Super Message for each Cloudpage view / visit (not unique visit, but actual hits).

So if your AJAX processing script manages to keep updating the data extension values upon each field change, then you will get a lot of action happening.

A method I did accomplish for a client, who needed a 'Language Changer' on their form i.e. a contact is redirected to a Preference Centre which is in English, they can select a language from a dropdown and it would save the language selection on their profile and refresh the page in their chosen language.

I accomplished this using a function :

function LanguageChanger() {
document.getElementById("overlay").style.display = "block";     
document.getElementById("submitted").value = "lang_change";    

LanguageChanger() was called as an OnChange action in the form:

     <select style="text-align: :right;
     float: right;" name="Language" id="Language" onchange="LanguageChanger()">
   <option value="en-GB" %%[IF @language=='en-GB' Then ]%% selected %%[endif]%% >English</option>
   <option value="fr-FR"  %%[IF @language=='fr-FR' Then ]%% selected %%[endif]%%>French</option>       

My processing page was the same as the form page, and upon Submit / Load there was a conditional statement to see if Language was changed :

Set @submitted = RequestParameter("submitted")
Set @Language = IIF(EMPTY(RequestParameter("lang")),'en-GB',RequestParameter("lang"))

/* LANGUAGE CHANGER SUBMIT - this has to be handled separately from a normal submit*/

  IF (@submitted == "lang_change")Then
          var @EmailAddress
          /*If yes then get all post values */
          Set @SubscriberKey = RequestParameter("email")
          Set @EmailAddress = RequestParameter("email")
          Set @Language = RequestParameter("language")

          /* Perform upsert */
          UpsertData('DataExtensionName',1,'EmailAddress', @EmailAddress, 
          'Language', @Language


Hope this helps as an explanation of how I got around the requirement. Again, this solution limits how many page calls are being made - it only loads for when a single field (Language) is changed.

  • i agree with you that Onchange() method will make multiple calls to cloud page but i have more then 10 fields in my form so i want to capture only the email address and may be First name to re-target them with email and i want to capture email address immediately when they enter it.
