From if-then to CASE-when


Recommended Posts

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.

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.

Please follow these link for more information:
