hide link if variable is empty
 

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%>

<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.
