How to Fix the Problem

Correct markup solutions

The aria-dialog-name rule has three markup patterns that pass test criteria:

<div role="dialog" id="alb" aria-labelledby="labeldiv"></div>

<div role="alertdialog" id="combo" aria-label="Aria Name">Name</div>

<div role="dialog" id="title" title="Title"></div>
  1. Ensure that each element with role="dialog" or role="alertdialog" has one of the following characteristics:

    • Non-empty aria-label attribute.
    • aria-labelledby pointing to element with text which is discernible to screen reader users.

Incorrect markup solutions

The aria-dialog-name rule has four markup patterns that fail testing criteria:

<div role="dialog" id="empty"></div>

<div role="alertdialog" id="alempty" aria-label=""></div>

<div role="dialog" id="albmissing" aria-labelledby="nonexistent"></div>

<div role="dialog" id="albempty" aria-labelledby="emptydiv"></div>
<div id="emptydiv"></div>

Why it Matters

Screen reader users are not able to discern the purpose of elements with role="dialog" or role="alertdialog" that do not have an accessible name.

Rule Description

Aria dialog elements must have discernible text that clearly describes the destination, purpose, function, or action for screen reader users.

The Algorithm (in simple terms)

Checks all elements with role="dialog" or role="alertdialog" to ensure that they have a discernable, accessible name.
