hi martin,
instead of resolving the path to your resource manually you can
use the asset service (useful when thinking of portlets)
i wrote a stylesheet component myself that works like your
script component :) ... and i enjoyed writing it.
public class Script {
@Inject
private AssetSource assetSource;
@BeginRender
boolean renderMessage( MarkupWriter writer ) {
....
Asset script = assetSource.findAsset(null, _src, null);
....
writer.element( "script",
"type", _type,
"src", script.toClientUrl())
}
@Component(parameters={"src=context:js/mainFunction.js"})
Script script;
g,
kris

T5 Script component [WAS: Re: T5 page lifecycle]
thanx, good to know that.
Although, I prefer having a template that can be further developed by
page designers, so I wrote a Script component that can be used like
this:
<script type="text/javascript" t:type="script"
src="js/main_functions.js"/>
The script component class:
public class Script {
@Inject
private Request _request;
@Parameter(required = true, defaultPrefix="literal")
private String _type;
@Parameter(required = true, defaultPrefix="literal")
private String _src;
@BeginRender
boolean renderMessage( MarkupWriter writer ) {
writer.element( "script",
"type", _type,
"src", _request.getContextPath() + "/" + _src );
writer.end();
return false;
}
}
Is there anything that could be improved?
Btw: I really love how easy it is to write a component in T5, you
just have to do what you want, nothing more - really, really nice!!
Cheers,
Martin
