Hi, If it's *completely unavoidable*, you can make the call synchronous. See the options page[1] for details. Making the call synchronous will lock up the UI of most browsers during the processing of the call.
So: * * * * function getResult() { var result; // Default to a failure result = (your failure return value here); // Do the request synchronously new Ajax.Request(url, { // Lock up the browser until this completes asynchronous: false, // On success, set our local variable to the result from the response onSuccess: function(resp) { result = resp.responseJSON.result; }, // Report failures and exceptions onFailure: function() { reportError('Request failed'); }, onException: function(req, ex) { reportError('Error: ' + ex); } }); // Done return result; } * * * * (The above assumes your request returns JSON.) But again, if you can possibly avoid it... [1] http://prototypejs.org/api/ajax/options HTH, -- T.J.
