redirecting to different pages depending on form fields chosen

[Anonymous]

I want the user to go to one default page when a certain product is selected in the form "multi-select" and to a different page when the user chooses the "None Apply" in the 'multi-select'.
This is the JavaScript taken and modified from Marketo help article:

<script type="text/javascript">

function changeFollowupURL()

{

    // first, set the default follow up page

    var URL = 'none';

     // override the default based on form values

     // Replace this with your own rules for setting the new URL

     if($jQ("#CitrixProducts").val() == "None apply")

     {

         URL = 'http://www.ncomputing.com/products/nseries';

         $jQ('input[name="returnURL"]').val(URL);

         $jQ('input[name="retURL"]').val(URL);

         $jQ('input[name="returnLPId"]').val('5025');

     }

    else

     {

        URL = 'http://www.ncomputing.com/products/vspace-platform';

        $jQ('input[name="returnURL"]').val(URL);

        $jQ('input[name="retURL"]').val(URL);

        //$jQ('input[name="returnLPId"]').val(URL);

     }

     return true;

}

 function formSubmit(elt) 

{

   changeFollowupURL();

   return Mkto.formSubmit(elt);

 }

</script>
Unfortunately I am not getting something right. I am a bit green with JavaScript so any help would be much appreciated.
Thanks

David,

Have you already defined $jQ to invoke jQuery? $jQ does not invoke jQuery by default. I don't see anywhere on your code defining $jQ.

The code looks like it should work but I think you need to define the variable $jQ like this:

var $jQ = jQuery.noConflict();

Try inserting that just before the "changeFollowupURL" function.

script type="text/javascript">
var $jQ = jQuery.noConflict();
function changeFollowupURL()

If you had already declared it, we can try looking at other options. Confirm that first.

Also, I am not sure about this line is needed on the code:
    $jQ('input[name="returnLPId"]').val('5025');
...if you are looking to only replace the return URL value.

Good luck!

Rafael

Can you post your page? What i'm missing is a way for the javascript function to be called. It seems to me that there needs to be an onClick trigger calling this function whenever someone selects a different value in your picklist.

The Javascript function is being called upon form submit. David has the overriding formSubmit() calling the changeFollowupURL() function.

i.e.

function formSubmit(elt) 

{

   changeFollowupURL();

   return Mkto.formSubmit(elt);

 }
