Browser Support

Internet Explorer Firefox Opera Google Chrome Safari

The disabled attribute for the <keygen> tag is supported in Firefox, Opera, Chrome, and Safari 6.


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.


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" />.
