Definition and Usage

The disabled attribute is a boolean attribute.

When present, it specifies that a <keygen> element should be disabled. A disabled field is unusable and un-editable.

The disabled attribute can be set to keep a user from using the field until some other condition has been met (like selecting a checkbox, etc.). Then, a JavaScript could remove the disabled value, and make the field usable.

Browser Support

The numbers in the table specify the first browser version that fully supports the attribute.

disabled Yes Not supported Yes 6.0 Yes

Differences Between HTML 4.01 and HTML5

The <keygen> tag is new in HTML5.

Differences Between HTML and XHTML

In XHTML, attribute minimization is forbidden, and the disabled attribute must be defined as <keygen disabled="disabled" />.
