Rails spinoffs - Jun 2008 - Ajax.Request - how to stop it going in constant loop?!

Hi,
I''m new to prototype and am having a problem with Ajax.Request. I find
that it basically just loops round and round and round forever, and
never finishes.

// uses ajax to attempt to connect to a database. Inserts either yes
or no into error div
function form_db(server, username, password, name)
{
  //alert(''hi'');
  new Ajax.Request(''ajax_handler.php'',
  {
    method:''get'',
    onSuccess: function(transport){
      var response = transport.responseText || "no response text";
      alert("Success! \n\n" + response);
    },
    onFailure: function(){ alert(''Something went wrong...'') }
  });

}

This just constantly alerts "success + " the correct response from
php, but it alerts again and again and again and never stops! If I
comment out the prototype code and uncomment alert(''hi''), that
only
alerts once so it must be a problem with the prototype usage. Could
someone explain to me how to get it to just do one request then
finish?

Thanks,
Simon

Any ideas? Apologies for what is probably a rather silly question, but
I''ve not had this problem when I made my own Ajax requester a while
back, and the docs haven''t explained to me how this one works - why
would it loop like this?!

I can''t think of any reason why you''re seeing this.  Can you
post a complete
page that demonstrates this?  You might be calling form_db() over and over
and not realizing it. Hard to tell.

I have the same issue. I''m using Ajax.PeriodicalUpdater. I want to
stop making calls based on condition. How do I do it?

You can call .stop() on your periodical updater object once you''ve
created
it.  Just have to save it away....

var updater = new Ajax.PeriodicalUpdater(...);
if (someCondition) updater.stop();

Different issue - what the OP posted doesn''t involve a
PeriodicalUpdater.

Can you post a little bit of your code that uses the PeriodicalUpdater, and
where you''re executing the logic where you want it to stop? 
It''s hard to
say much more than what I posted without being able to see how you''re
using
it.
