From if-then to CASE-when

[bookish]

HI! Could anyone help me transform this code to a CASE-when scenario?

<script>
if ([@field:amount] == "0")
   {
      document.write("No Signup Yet");
    }
else if([@field:attendees] < [@field:max_attendees])
   {
      document.write("<a href='URL?ID=[@authfield:ID]&activity=[@field:activity]&amount=[@field:amount]'>Signup Here</a>");
    }
else if ([@field:waitlisted] < [@field:max_waitlist])
   {
      var test='Closed. <a href="URL?ID=[@authfield:ID]&activity=[@field:activity]&amount=';
      var countr = '[@field:country]';
      if ((countr !="country1")&&(countr !="country2"))
         {
            if('[@field:activity]'=="activity1")
               {
                  test=test+'[@field:amount1]';
               }
            else
               {
                  if('[@field:activity]'=="activity2")
                     {
                        test=test+'[@field:amount2]';
                     }
                  else
                     {
                        test=test+'[@field:amount]';
                     }
                }
         }
      else
         {
            test=test+'[@field:amount]';
         }
      test=test+'">Waitlist me</a>';
      document.write(test);
   }
else
   {
      document.write("<div>Signup & Waitlist Closed</div>")
   }
</script>

Hi @bookish,

Unfortunately, this code cannot be fully transformed into the Case-When scenario since HTML elements, for example, links, are rendered as a plain text. This code can be transformed into the Case-When scenario only partially and with the additional JavaScipt code.  If you would like to, I could try to create it for you.

Sorry for the late reply. If you could try it, please do. Please remove anything on Waitlist as we don't have waitlist anymore. Thanks much!

Hi @bookish

Please clarify about Waitlist - which parts of the code you want to leave and which remove?

[bookish]

HI Alison,

The results should only be NO SIGNUP YET, SIGNUP HERE and SIGNUP CLOSED.

Hence: please remove  any reference to waitlist like:

a. here in else if([@field:attendees] < [@field:max_attendees])

b. or here in test=test+'">Waitlist me</a>';

c. the last part should just say  document.write("<div>Signup Closed</div>"), removing "& Waitlist "

Thanks!

Hi @bookish,

Unfortunately, it cannot be transformed into the Case When statements due to the fact that there still will be a lot of JavaScripts inputs. If you want to make inputs to the datapage without rewriting the whole HTML page, like the document.write method does, I can suggest that you replace the document.write  with the appendChild or innerHTML.

Thank you @Alison for the efforts and the links.  Happy new year!
