G80: Providing a submit button to initiate a change of context

Important Information about Techniques

See Understanding Techniques for WCAG Success Criteria for important information about the usage of these informative techniques and how they relate to the normative WCAG 2.0 success criteria. The Applicability section explains the scope of the technique, and the presence of techniques for a specific technology does not imply that the technology can be used in all situations to create content that meets WCAG 2.0.

Applicability

Content that includes forms.

This technique relates to:

Success Criterion 3.2.2 (On Input)
- How to Meet 3.2.2 (On Input)
- Understanding Success Criterion 3.2.2 (On Input)

Description

The objective of this technique is to provide a mechanism that allows users to explicitly request changes of context. Since the intended use of a submit button is to generate an HTTP request that submits data entered in a form, this is an appropriate control to use for causing a change of context and is a practice that does not create confusion for users.

Examples

Example 1

Example 1: A submit button is used for each form that causes a change in context.

Resources

Resources are for information purposes only, no endorsement implied.

Tests

Procedure

Find all forms in the content
For each form, check that it has a submit button

Expected Results

#2 is true

If this is a sufficient technique for a success criterion, failing this test procedure does not necessarily mean that the success criterion has not been satisfied in some other way, only that this technique has not been successfully implemented and can not be used to claim conformance.
