[t5] Is there anyway of passing parameters to expressions?
Sorry for the strange subject :D, but i don't know the correct way to name
it. I have something that looks like this:
<script type="text/javascript">
function showWindow2()
{
${window2.componentResources.id}.setTitle("Ayuda")
${window2.componentResources.id}.setURL("${generarEnlace}");
${window2.componentResources.id}.showCenter()
}
</script>
But I would like to do something like adding two params to ShowWindow2
function and pass them to "generarEnlace". The thing is that... it could be
possible?
My final goal is to develop the functionality of helping links with modal
windows, where un link looks like this:
javascript:showWindow2(12,35)
javascript:showWindow2(12,37)
Each number are id's of form and field, respectively.
Thanks in advance for the support ;D

I don't see why not. Make a .js file with the function
function setupHelp (win2id, generarEnlace)
{
$('clickable_thing').observe('click', function(event) {
win2id.setTitle("Ayuda")
win2id.setURL(generarEnlace);
win2id.showCenter();
});
}
where 'clickable_item' is the html id of something that you want to
have pop up the help window when clicked. Then use @IncludeJavaScript
to add that .js file to your component. Inject RenderSupport and then
override afterRender:
void afterRender ()
{
_renderSupport.addScript("setupHelp(%s, '%s');", window2.componentResources.id,
generarEnlace.toString());
}

Hi,
I assume the URL you set on window2 is for a page. In that case you can
get the base URL from componentResources.createPageLink("pagename",
true) and attach the form and field ids in your JavaScript:
${window2.componentResources.id}.setURL("${basehelpurl}/" + formId + "/"
+ fieldId);
You can then get the form and fields ids from onActivate(int, int) on
your help page. That's the quick and dirty way, anyhow.

Hello,
This is a classic case of needing client-side behavior with server-side
knowledge, and would be handled well by OO javascript. You could create
a component for this but is seems like a mixin might be more
appropriate. Checkout this article:
http://wiki.apache.org/tapestry/Tapestry5AndJavaScriptExplained
It goes through the steps of creating a mixin fundamentally similar to
what you need. You also might checkout the chenillekit / t5c window
component.
