Trick for NOT rendering some html tag ?
Hi.
Developing web applications, in various frameworks, I came to one problem,
although simple, always makes little mess in template...
For example, let's say you want to print bold some text depending upon some
condition. If condition is not met, than I would like to be printed
normally. Straitforward way is:
<span jwcid="@Conditional" condition="ognl:someCondition">
<b>
Stuff to be printed ....
</b>
</span>
<span jwcid="@Conditional" condition="ognl:!someCondition">
Stuff to be printed ....
</span>
So we have a lot of duplicated html stuff just because this simple
requirement. Especially when this wrapped stuff to be printed is really
long.
Is there maybe some easier way to acomplish this task... Looking at
Tapestry, I wouldn't say so, but maybe someone has found some neat trick
that would be like :
<b jwcid="@SomeComponent" element="b" condition="ognl:someCondition">
</b>
thus <b> tag would be rendered only if condition is met, otherwise nothing
would be rendered ?

Vjeran,
I think you could certainly simplify this with the use of style sheets and
the "Any" component. Something like:
<span jwcid="@Any" class="ognl:myStyle" element="span">
Stuff to be printed ....
</span>
.java:
public String getMyStyle() {
return (getSomeCondition())? "boldText": "regularText";
}
Hope that helps.
Eric

A quick fix could be as simple as this:
<span jwcid="@Any" element="ognl:someCondition ? 'b' : 'span'">
Stuff to be printed ...
</span>
