hi,
I have an idea, maybe you can use this function in next ipb versions: http://prototypejs.org/api/form/request
if i want send a new parameters with ajax i must change javascript file but if you use this function i can edit html with hook and finish.

That is a prototype function, and IP.Board does use prototype, so I'm confused: what exactly are you asking to have changed?

see if i want send a new parameters with new ajax post i can't send this Without change js file. but with this function i can add input tag to form and finish.

I think, the calls, where applicable, comments and topic fast reply.

new Ajax.Request( url,

...

for

$(ipb.topic.fastReplyId).request(

...

and such... relates actually rather directly to an open bug report where data hooks do not get the expected values added to the form populated in the ajax request.
