Thanks Elin, but the answer which I found after spending some time analyzing other components was:

1. You should get the data which posted by previous page by this command:

   $jApp = JFactory::getApplication();
   

2. It is a Array which you should look for specific key "cid" in it by this code:

   $ids  = JRequest::getVar('cid', array(), '', 'array');
   

3. You have the id of that rows in an array, now you can do something like this:

   foreach ($ids as $i => $id)
   {
     $query = $db->getQuery(true);
     $db->setQuery($query);
     //some code
     $db->query(); // to do change in DB
     $results += $db->getAffectedRows();
   }
