Re: T5: Javascript problem

I dont like this way of refering to nodes (  document.entryForm.oosComment )
i'm not sure how many browsers fully support this but it looks like
this can work
when nodes have the name attribute set.

If i remember correctly, T5.1 used to include a name in each form but
this was removed
in 5.2 - see https://issues.apache.org/jira/browse/TAP5-796

So, anyway, see if your nodes have id, and just reference them in that
way using either
document.getElementById or prototype's $$

 Hi!



 Another simple question.



 I had an application running under T5.1 and I've now moved to 5.2. I
 notice my Javascript is now broken. I have this function in my .tml
 file:



 SCRIPT type=text/JavaScript LANGUAGE=JavaScript



 function checkOOS(myCheck)

 {

   if(myCheck.checked)

   {

      document.entryForm.oosComment.disabled = false;

      document.entryForm.oosComment.focus();

   }

   else

   {

      document.entryForm.oosComment.disabled = true;

   }

 }



 /SCRIPT



 Which turns a select on and off by clicking a checkbox via onclick.
 While the JavaScript function is called, it no longer updates the
 disabled attribute of oosComment.



 Should I be adding my JavaScript with JavaScriptSupport (and if so,
 where is documentation or an example? The only mention of JavaScript I
 can find is in the HOW-TOs which show it being added to the .tml file
 directly in a script block).



 Also, why is this now partially non-functioning in 5.2? It seems that
 document.entryForm.oosComment.disabled is incorrect for referring to
 component oosComment. Yet this works fine under 5.1. My Form is called
 entryForm and oosComment is inside that. The page hasn't changed since
 it worked under 5.1 but, in that case, it seems I've been doing
 something wrong all along even though it worked.

Thanks Andreas.

Yes, name attribute was the problem. I've changed to using getElementById and 
it's working again.

I haven't read precisely your mail but I think I can answer that part...

I 've been reading the mailing list for a while and I think adding
javascript blocks is not recommended, instead you should write javascript in
.js files and add them by means of annotations in the Java class.

About t5/js documentation I can tell you about this link I found useful:

http://wiki.apache.org/tapestry/Tapestry5AndJavaScriptExplained

please take into account that annotation's names may vary between version
5.1.x.x and 5.2.x.x... I don't remember quite well about that.

finally you can browse mailing list archives:

http://tapestry.1045711.n5.nabble.com/Tapestry-User-f2375125.html

hope that helps

cheers.

Nicolas.-

Yes, it's true it might not be the fastest or easiest way, but
I think it's good that Tapestry forces you to things the right way.

Re: T5: Javascript problem

2010-12-16 Thread Richard Hill

One use case I have for putting javascript in .tml is to get a function
to execute after a zone update. Due to Tapestry attaching onclick event
handlers to actionlinks (as opposed to using onclick attribute), it's
not that easy afaik to guarantee your own method will get called
afterwards (the DOM standard does not specify in which order attached
events should be fired). So at the bottom of my zone I have a
scriptmyFunction();/script block.

Seems to work, although is probably a horrible hack and not the right
way to do things... :)
