An HTML form with a disabled input field:
The disabled attribute is a boolean attribute.
When present, it specifies that the <input> element should be disabled.
A disabled input element is unusable and un-clickable.
The disabled attribute can be set to keep a user from using the <input> element until some other condition has been met (like selecting a checkbox, etc.). Then, a JavaScript could remove the disabled value, and make the <input> element usable.
Tip: Disabled <input> elements in a form will not be submitted.
Note: The disabled attribute will not work with <input type="hidden">.
The numbers in the table specify the first browser version that fully supports the attribute.

NONE.
In XHTML, attribute minimization is forbidden, and the disabled attribute must be defined as <input disabled="disabled" />.
