    « HTMLIsIndexElement

    This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

    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.


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


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