About

Version:	WCAG 2.0 and up
Number:	3.2.2
Level:	A
Applicability:	Controls Inputs Links
Requirement:	Changing the setting of any user interface component does not automatically cause a change of context unless the user has been advised of the behavior before using the component.
Guidance:	Understanding Success Criterion 3.2.2 How to meet Success Criterion 3.2.2
Techniques:	G13: Describing what will happen before a change to a form control that causes a change of context to occur is made G80: Providing a submit button to initiate a change of context H32: Providing submit buttons H84: Using a button with a select element to perform an action SCR19: Using an onchange event on a select element without causing a change of context

Purpose

The purpose of this success criterion is to ensure that users do not trigger unexpected actions that change the context (e.g., submitting a form, spawning a new window, changing focus to another element, changing the text) when they input values.

Not all users can perceive that the context has changed, or they may have difficulty keeping track of such changes.

How to Meet

Authors need to ensure that when a user enters data or changes a setting it does not trigger an event that will cause a context change.

If a change of context must occur, authors need to ensure that users are informed of the actions before inputting information.
