Assigning Initial Input Values to

You can set any input radio or checkbox when they are created.

• This is accomplished by using the CHECKED attribute.
• Simply adding this attribute to a radio or checkbox INPUT tag will cause that INPUT to be selected as soon as the page is loaded (or reloaded).

For example, suppose you're going to ask a question you're pretty sure you know the answer to, but can't be completely certain.

Are you awake at the moment? Yes No

The HTML to produce the above is:

Are you awake at the moment?
  <INPUT type="radio" name="awake" 
         value="Y" checked>Yes
  <INPUT type="radio" name="awake" 
         value="N">No

Obviously, you will want to use CHECKED on only one option in a radio-button logical input, as shown above, but multiple checkboxes in a given logical input could be set as CHECKED.

Text inputs and buttons to select are all very nice, but they clutter up the screen and get a little boring after a while.
