Hi Monika,
It can be tough in lists to know when you've reached the last item. It's
usually easier to know when you're on the first one, so I'd suggest looking
at it the other way around:
Include a comma at the start of every item, except for the first one.
You're already using a pre-execute block mark, so all you need to do is
introduce a counter. Set it to 1 before you start your list; check its
value at the start of your collection and only output the comma if the
value is greater than 1. Oh - and don't forget to increment it each time
as well :)
I haven't tested it, but something like this:
<!IoRangePreExecute><% counter = 1 %><!/IoRangePreExecute>
{"Image": [<!IoRangeList><!IoRangeRedDotMode><!--<%lst_plSW%>--><
!/IoRangeRedDotMode><!IoRangePreExecute><% if "<%std_url%>" <> "" then %>
<!IoRangePreExecute><% if counter > 1 then %>,<% end if %><
!/IoRangePreExecute>
{ "YouTube-Titel": "<%hdl_ueberschrift%>",
"Hersteller": "<%!!
Context:Pages.GetPage(Guid:<%inf_pageGuid%>).MainLink.OwnerPage.Headline
!!%>",
"Kategorie": "<%ol_videoTyp%>",
"URL": "<%std_url%>"
}
<% counter = counter + 1 %>
<% end if %><!/IoRangePreExecute><!/IoRangeList>
]}
Good luck,
Mark
