I'm having trouble setting the input focus when validating fields in a form. I have a very simple case below, that validates a field for white space. If it has white space, it triggers an alert and I'd like the focus to stay in that field. However, when tabbing, it moves to the next field regardless.
I'm using the blur event to validate the field. I'm returning false when it has white space. I've even tried forcing the issue by setting the focus to the field, and that doesn't work either. I must be misunderstanding something. Anyone able to set me straight?
