As long as the ajax request is asynchronous, the browser can make the
request to the server, the server can process the request and insert the
record then return back the value of the inserted id. Have the aspx
page echo the id (or 0 on failure) and define your onSuccess function
along these lines:
onSuccess: function(transport) {
var id = parseFloat(transport.responseText);
if (id) {
note.id = id;
note.status = 'saved';
} else {
note.status = 'failed'
}
}
The onSuccess should be fired after the aspx page is done processing and
will receive the output of the aspx page in transport.responseText
