HTMLIsIndexElement

The HTMLIsIndexElement interface provides special properties (beyond the regular HTMLElement interface it also has available to it by inheritance) for manipulating <isindex> elements.

The <isindex> element has been deprecated in HTML4 and removed in HTML5. This latest specification requires that this element implements HTMLUnknownElement rather than HTMLIsIndexElement.

Properties

Inherits properties from its parent, HTMLElement.

HTMLIsIndexElement.form Read only

Is a HTMLFormElement representing the <form> element it belongs too. It can have the null value, if <isindex> isn't part of any form.

HTMLIsIndexElement.prompt

Is a DOMString representing a text to be prompted for the field.

Methods

No specific method; inherits methods from its parent, HTMLElement.
