I am building a form that, based on whether a text box is filled in or not, either enables or disables certain form fields. What I'm seeing is that there is a noticeable delay as you leave the text field to see the following fields either enable or disable. Is there a more responsive javascript technique than using onchange? Also, what kind of overhead does it entail? I'd be using the technique across a form with hundreds of inputs...
