simple IF .. ELSE statement [message #24064]

Hello,
JET has a <c:if> tag but not a "else" one. I'm using it to verify that a
reference exists and I'd like to know how to do simply the ELSE case:

<c:if test="$currClass/myreference">
<%-- reference exists --%>
</c:if>
else ?
<%-- reference doesn't exists --%>

Thank you,
Tex.

Hello,

I already had this problem and you should maybe use <c:choose...> tag :

<c:choose>
<c:when test="[insert your 'if' condition here]">
handle case 1
</c:when>
<c:otherwise>
handle other cases
</c:otherwise>
</c:choose>

Hope it helps.

Aleks

Hello,
yes I was thinking about it but it is a bit complicated just for an "else"
Isn't there an equivalent of NOT in JET ( "!" in C/C++ .. ) :
<c:if test="$currClass/myreference">
<%-- reference exists --%>
</c:if>
<c:if NOT test="$currClass/myreference">
<%-- reference doesn't exist --%>
</c:if>

Tex:

There is a 'not'. It is an XPath function...

<c:if test="$currClass/myreference">
<%-- reference exists --%>
</c:if>
<c:if test="not($currClass/myreference)">
<%-- reference doesn't exist --%>
</c:if>
