Hi,

Can anybody tell me why in the following peace of code the link does
not get hidden when "locationid" is empty? thanks, torsten

<%if IsNull(cursor("locationid")) = false then %><A
href="javascript:MM_openBrWindow('http://www.mapminder.co.uk/getmap/default.asp?page=viewlocation&locationid=<%
=cursor("locationid")
%>&source=82YWNH0INZZDY-zIkhkce2L£wY!Pbgx6&zoom=<%
=cursor("mapbytezoom")
%>','','toolbar=0,location=0,directories=0,status=1,menubar=0,scrollbars=1,resizable=0,width=585,height=585,screenX=0,screenY=0,top=0,left=0');"
onMouseOver="window.status = 'Link To Location Map'; return true;"
onMouseOut="window.status = ''; return true;"><IMG
SRC="../images/pubs/gpg_getmap_button.gif" WIDTH=58 HEIGHT=38 HSPACE=0
VSPACE=0 BORDER=0 ALT="Get Map"></A><% end if%>

  1. <c:if test="${not empty urldata}"><a href="<c:out value='${urldata}'/>"><c:out value="${urldescription}"/></a></c:if>

Now isn't that a simple and clean bit of code?
Learn to use JSTL and ditch those scriptlets. They're 7 year old technology and no longer recommend.
In fact on any new project I ban the use of scriptlets, dictate JSTL is used exclusively.
Any JSP containing scriptlets gets thrown back to the programmer for rework.
As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.
