Rails spinoffs - Nov 2007 - Start and stop the Ajax.PeriodicalUpdater in tow different functions?

Hi,

I have a simple function that is called when the user clicks on an
"Edit" button:

function startEdit(id) {
  new
Ajax.Request(''modules/main.php?action=startEdit&type=ajax&id=''
+
id, {
    onSuccess: function(transport) {
      var observer = new Ajax.PeriodicalUpdater(''time'',
''modules/
main.php?action=activeRecord&type=ajax'', {
        method: ''get'', frequency: 10
      });
    }
  });
}

The function copies a record from an DB into a temporary table (via
Ajax.Request) and on success it starts the Ajax.PeriodicalUpdater.

In a second function I''ve tried to stop this Ajax.PeriodicalUpdater
when the user clicks the "Cancel" button but without any success.
I''ve
tried it this way:

function cancelEdit() {
  observer.stop();
}

The "var observer" is no longer present to stop it and the
Ajax.PeriodicalUpdater is still running. How can I stop it?

Thanks for any tipp!

Frank

The var oberver is no longer present.

When, in the first function, you declare "var observer", you are
declaring a variable local to the scope of that function. So, dropping
the var should work, as you want observer to be a global variable.

Best,
