+# 3.2.2 On Input
+
+- Level: A
+- Guideline: 3.2 Predictable
+- Principle: 3 Understandable
+
+## What it is
+
+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.
+
+## How to test
+
+- Check: 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.
+- Use the sufficient techniques below as acceptable methods when applicable.
+- Confirm none of the common failures apply.
+
+## Sufficient techniques (W3C)
+
+- 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
+- PDF15: Providing submit buttons with the submit-form action in PDF forms
+- G13: Describing what will happen before a change to a form control that causes a change of context to occur is made
+- SCR19: Using an onchange event on a select element without causing a change of context
+
+## Advisory techniques (W3C)
+
+- G201: Giving users advanced warning when opening a new window
+
+## Common failures (W3C)
+
+- F36: Failure of Success Criterion 3.2.2 due to automatically submitting a form and presenting new content without prior warning when the last field in the form is given a value
+- 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
