    Using the aria-required attribute

    Description

    The aria-required attribute is used to indicate that user input is required on an element before a form can be submitted. This attribute can be used with any typical HTML form element; it is not limited to elements that have an ARIA role assigned.

    HTML5 now has the required attribute, but aria-required is still useful for user agents that do not yet support HTML5.

    Value

    true or false (Default: false)

    Possible effects on user agents and assistive technology 

    Screen readers should announce the field as required.

    Note that this attribute will not automatically change the presentation of the field.

    Note: Opinons may differ on how assistive technology should handle this technique. The information provided above is one of those opinions and therefore not normative.

    Examples

    Example 1: A simple form

     

     <form action="post">
         <label for="firstName">First name:</label>
         <input id="firstName" type="text" aria-required="true" />
         <br/>
         <label for="lastName">Last name:</label>
         <input id="lastName" type="text" aria-required="true" />
         <br/>
         <label for="streetAddress">Street address:</label>
         <input id="streetAddress" type="text" />
     </form>
