that is the html code I do send after an ajax.updater call.
-----------------
<div id="parent">
<div id="the_id_xyz" >
here html
</div>
<script type="text/javascript">
getData=function(){
return {id:''the_id_xyz'',some_more_data:''data data
data''};
}
</script>
---------------------
further I do have my ajax updater like build laike this
function myUpdateFunc (){
var myAjax = new Ajax.Updater(
''parent'',
url,
{
method: ''get'',
parameters: pars,
insertion:Insertion.Bottom,
onComplete:registerHtmlCode
evalScripts: true
});
}
and somwhere else
function registerHtmlCode(){
var newData=getData();
... do some more funny things with the newData
}
from prototype API doc:
"The local scope will be that of Prototype''s internal processing
function. Anything in your script declared with var will be discarded
momentarily after evaluation, and at any rate will be invisible to the
remainder of the page scripts."
So believing this I do get by the first call to myUpdateFunc the
callback function do get the correct data out of the getData function.
The second time a call myUpdateFunc the value I do get back out of
getData is the data corresponding to the first call. My reading of the
doc let me think that once the getData is reevaluted the value should be
the value send with the html code.
I want to have with the call to getData() some info about what I just
inserted, this without having to query my DOM.
Is my reading of the doc correct. Has this construct some chances to work.
Thanks for any explanation, hint, remarks

cedric, Unless your method, registerHtmlCode, is altering what getData returns (it doesn''t look like it, from your example code), then I don''t see how the result from calling getData will ever change. Can you post the real code you are using instead of the simplified version? -justin --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

here the ajax updater
--------------------
function getSnippsetAlbum(albumId){
var url = ''/snippset/albumpicture/''+ albumId ;
var pars = null;
var myAjax = new Ajax.Updater(
''album'',

insertion:Insertion.Bottom,
onComplete:registerAlbum,
evalScripts: true
});
}
--------------------------
one result to a call
--------------------

Instead of redefining the getData function on every request why not just make getData return a dynamic object instead of one with hardcoded values? What you''re probably running into is the function is not getting redefined until after the request is completed, so when you call getData, you''ll always be one step behind. -justin --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

The getData definition is put together on the server. There I know everything about what I''m sending to the client. So I trying not to do the same work twice once on the server, once on the client side.

It ''s like a data > accessor on the html snippset.I''m not really sure what you''re trying to do here, but maybe you could just set some variables and have your function return those instead of redefining the function, such as: var Data = { id:null, name:null, get: function(){ return { id: this.id, name: this.name }; }, set: function( id, name ){ this.id = id; this.name = name; } } Then your Ajax responses would have some JavaScript like: Data.set( ''my new ID'', ''my new name'' ) And your registerAlbum would be modified to be: function registerAlbum(){ var albumData=Data.get(); albumColl.add(new Album(albumData)); } Hope this makes sense. There are many different ways to accomplish what you are trying to do, this is just one example. -justin --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

Your vision of my problem gives me a new insight. thanks, i''ll have a go and keep you/the list posted. have a nice evening/day/whatever cedric --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

The solution having a "dynamical object" proves to be almost satisfatory. The obvious solution is to have the call to registerAlbum in the evaluated script coming with the html snippset. That made my day.
