Technique F37:Failure of Success Criterion 3.2.2 due to launching a new window without prior warning when the selection of a radio button, check box or select list is changed

About this Technique

This technique relates to 3.2.2: On Input (Failure).

This failure applies to HTML.

Description

This document describes a failure that occurs when changing the selection of a radio button, a check box or an item in a select list causes a new window to open. It is possible to use scripting to create an input element that causes a change of context (submit the form, open a new page, a new window) when the element is selected. Developers can instead use a submit button (see Providing a submit button to initiate a change of context) or clearly indicate the expected action.

Examples

Example 1

The example below fails the success criterion because it processes the form when a radio button is selected instead of using a submit button.

Tests

Procedure

Find each form in a page.
For each form control that is a radio button, check box or an item in a select list, check if changing the selection of the control launches a new window.
For each new window resulting from step 2, check if the user is warned in advance.

Expected Results

If check #3 is false, then this failure condition applies and content fails the Success Criterion.
