converting component output to javascript

[Danny Mandel <dm...@tolweb.org>]

Hello fellow tapestraniacs.  I am looking to somehow take the output 
from one of my components and convert it into a javscript variable that 
can be referred to from elsewhere on a page for mouseover events.

Right now I have a component that will generate a table with a listing 
of all metadata associated with a given img and I want to be able to use 
a similar component to generate a javascript variable holding the html 
for the table. 

Ideally I'd use a script specification for this, but I don't know how 
(or if it's possible) to render other components inside a .script file.  
Has anyone come across this problem before and found a nifty solution?

Thanks.

Sincerely,
Danny Mandel

I think it might be possible to render a component into a String and
pass that string to the script. I haven't tried it myself, but here is
what I would do:

Create a HTMLWriter that writes to a StringWriter:

StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
IMarkupWriter writer = new HTMLWriter(pw);

Render your component to that IMarkupWriter:

IComponent component = getMyComponent();
IRequestCycle cycle = getRequestCycle();
component.render(writer, cycle);

Pass the result to your script:

writer.flush();
String html = sw.toString();
writer.close();

Map symbols = new HashMap();
symbols.put("html", html);
getScript().execute(cycle, body, symbols);
