"user"-arguments on the "onSuccess"-method possible?

Hi,
is it possible to get some "user"-arguments on the
"onSuccess"-method
of the Ajax.request object?
Something like this (look out for "mydata"):
-------------------------------------------------------------------------------------------------------------------------------------------------
var mydata_class = Class.create();
mydata_class .prototype ={
	initialize:function(){
		this.Images=null;
	}
};

var mydata = new mydata_class()

new Ajax.Request("/system/classes/d4pc/Misc/DiaShow/API.php",
			 {
				method:''get'',
				parameters:request,
				onSuccess:Update_onSuccess(response,mydata),
				onFailure:this.DiaUpdate_onFailure
			}
);

function Update_onSuccess(response,mydata){
           var rpc= eval
(''(''+response.responseText+'')'');
	   mydata.someproperty= rpc.images;
};
-------------------------------------------------------------------------------------------------------------------------------------------------

If I do so, "response" will be empty. Is there a way to get this thing
done?

Andreas

Re: "user"-arguments on the "onSuccess"-method possible?

You could try:
 new Ajax.Request("/system/classes/d4pc/Misc/DiaShow/API.php",
 			 {
 				method:''get'',
 				parameters:request,
 
onSuccess:function(response){Update_onSuccess(response,mydata);},
 				onFailure:this.DiaUpdate_onFailure
 			}
)

I''m not sure on the exact syntax, but that is the trip I have used in
the
past. Create an anonymous method that calls the correct one with the correct
parameters.

Hi, I''ve tried your code, but it didn`t work. Like my own code ;-)
The second parameter works fine, but the ajax.request-result is empty.
I''ve postet my complete code to specify what i want.

AW: [Rails-spinoffs] Re: "user"-arguments on the "onSuccess"-methodpossible?

Yes you are right,
But than i have to code mydata hard to Update_onSuccess and that''s bad
because i want to build an DiaShow-class to have eventually a number of
instances running on one Page. If i do so like you have shown me, all
instances will use the same "mydata", and than the trouble begins...

Look at this and it will be clear i think:

If you reference a variable that exists outside of the function declaration,
it will create a closure, so any time that function is called it will be
acting on that variable even though it is outside the functions scope. This
is how Prototype''s "bind" function works, which could also be
used here to
"bind" extra variables to that function.

var mydata = new mydata_class();

function Update_onSuccess(response){ //don''t add "mydata" as
an argument
  var rpc= eval
(''(''+response.responseText+'')'');
  mydata.someproperty= rpc.images; //this creates a "closure" around
"mydata"
};

//now any time Update_onSuccess is called, it is as if mydata was passed as
an argument

new Ajax.Request("/system/classes/d4pc/Misc/DiaShow/API.php", {
  method:''get'',
  parameters:request,
  onSuccess: Update_onSuccess, //just pass the function itself, it already
has access to mydata
  onFailure: this.DiaUpdate_onFailure
});

function Update_onSuccess(response,mydata){
           var rpc= eval
(''(''+response.responseText+'')'');
	   mydata.someproperty= rpc.images;
};

If I do so, "response" will be empty. Is there a way to get this thing
done?
