Two trigger to one function ? [keyup and focusout]

You can use .bind() which takes a space separated list of events to bind your handler to, like this:

$('#myfield').bind("keyup focusout", function () {
  //do something
});

Though, unless you need some special propagation, I'd stick with blur over focusout, just a preference really:

$('#myfield').bind("keyup blur", function () {
  //do something
});
