Chapter 20. User Interface > user-input Property

20.12. user-input Property

The user-input property is designed to allow a Web author to specify whether a given user-interface element can accept input from the user. The principle reason for having such a property is to selectively enable or disable inputs interactively. For example, say you have a form where you are seeking the user's address. If the user lives in a city, you might want to disable a rural route setting. If the user lives in a house, you might want to disable a post office box field or an apartment box field selectively — and the user-input property will enable you to do these things when used in a program.
