Browser Support

Internet Explorer Firefox Opera Google Chrome Safari

The disabled attribute is supported in all major browsers, except Internet Explorer.

Note: Even if the disabled attribute works in Safari, Safari does not support the <keygen> element.

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.

Syntax

<keygen disabled="disabled" />

Note: The disabled attribute is a boolean attribute, and can be set in the following ways:

  • <keygen disabled>
  • <keygen disabled="disabled">
  • <keygen disabled="">
