WCAG 2.0 AA Compliance

Section 3.2.2

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.

This is the same as Section 3.2.1 except it applies to the onchange attribute instead of onfocus. Your onchange attribute shouldn't do any of the following:

  • Change focus to another element inside the webpage.
  • Change the URL location of the webpage (thus loading another webpage).
  • Submit forms automatically.
  • Launch new windows.

If any elements do the above when an element is changed, it violates this section. Instead of using onchange, you should instead use submit buttons that will relay the message "Do it," "Go," or even "Apply changes."
