Ajax and Provisioning module

[vkusno]

Hello everyone. I am writing a provisioning module and want to use Ajax to call certain functions.

The problem is that if i implement a function, for example, mymodule_reboot($params) i can access it by submiting a form like:

                        <form id='actionForm' method="post" action="clientarea.php?action=productdetails">
                               <input type="hidden" name="id" value="{$serviceid}" />
                               <input type="hidden" name="modop" value="custom" />
                               <input type="hidden" id='action' name="a" value="reboot" />

But that at the end produces the whole page output which is not OK since i want to use Ajax. I thought maybe it is possible to supress output somehow and force whm to print only the "return" value of a function?

Yes maybe the way to solve this is to create a single php file with dbconnect include and do what i want there, but how do i get $params variable with all the info i need? including something else + API calls?
