Hi,
For a project I am wokring on I often need image enlargements. The image showed on the
web page is small
and when clicked on, a new window is openned with a larger version of the image. The
source code often looks like this
(simplified)
<mm:relatednodes type="images" max="1">
<mm:field name="number">
<a href="<mm:url page="/zoom.jsp"/>?number=<mm:field name="number"/>">
</mm:field>
<img src="<mm:image template="s(120)"/>" border="0"/>
</a>
</mm:relatednodes>
sometime the image needs to be aligned right or the "preview" image need to be 140
pix. this usualy resul in "My" website to be full of code that looks about the same
but with small differences.
what I would like is to create a "simple tag" that does this for me. so that the code
can look like this:
<mm:relatednodes type="images'>
<keesj:image enlagement="true" template="s(120)"/>
</mm:relatednodes>
since that is not possible i used a dynamic jsp include that take parameters it now
looks like this
<mm:relatednodes type="images" max="1">
<mm:include page="/frontend/generic/beeldvergroting_source.jsp">
<mm:param name="img"><mm:field name="number"/></mm:param>
<mm:param name="align">right</mm:param>
</mm:include>
</mm:relatednodes>
and so accepts some optional parameters and uses so default parameters
how do you solve such problems?
is there a need to have "scriptable tags"?
greetings
