Thanks Norman and Ulrich for your quick response. Now I am getting
closer. In my scenario, I want to append a dynamic content to the
"onclick" attribute, not to replace it entirely. See below,

<input jwcid="@Any"
onclick="document.getElementById('positionId').value=" type="submit" /> 

How can I append OGNL expression to the "onclick" attribute?

Not sure on that one, I don't believe there really is anything  
dealing with layout other than a table.

The Any component is what you want, I believe:

<input jwcid="@Any" type="submit" value="ognl:value"/>
