Client side validation script needs to perform below steps to satisfy Checkpoint AA3.3.3: *WCAG 2.0 AA* Error Suggestions

[Satya Minnekanti]

These techniques are defined in WCAG 2.0 Level AA Success Criterion 3.3.3. ​http://www.w3.org/TR/UNDERSTANDING-WCAG20/minimize-error-suggestions.html

when user leaves a mandatory field empty

1. Client-side validation script should display a WAI-ARIA alert message to notify the user that the field is required.

2. Validation script should add an aria-invalid="true" to the <input> element to inform a screen reader user that the input is invalid.

3. Field label is changed so that the user can easily identify the field where information must be entered.

When user enters an input that falls outside the required format or values.

1. Client-side validation script should display a WAI-ARIA alert message.

2. WAI-ARIA alert message describes the nature of the error and the expected values to enable the user to correct the invalid input.

3. validation script should also add an aria-invalid="true" to the <input> element to inform a screen reader user that the input is invalid.

Validation is to be performed by the application using CKEditor, not by the editor itself. Can you please explain the features you feel are missing on the editor to be able to achieve this?

CK Editor needs to add aria-invalid="true" to the <input> fields that

1) is Mandatory and left blank

2) needs a required from of input for ex: width & height fields.

Ah, ok... you just forgot to mention what you're talking about: CKEditor dialogs.
