Input fields are usually associated to forms, but I would like to use them in a simple Javascript/HTML page. I don’t need the form. I see no issue with my HTML page, but is there any danger or bad practice I am not aware of? I just don’t want my page to bug down the road.
(Basically, a field in my page can be Javascript enabled or disabled according to values in other fields)
You should be fine AFAIK. It’s ok in the HTML 4.01 standards anyway
