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.
Adobe Flash Professional version MX and higher
Adobe Flex
This technique relates to:
See User Agent Support Notes for FLASH4. Also see Flash Technology Notes.
The objective of this technique is to use submit buttons to allow users to take actions that cause changes of context rather than allowing changes in context to occur when the value or state of a non-submit button control is modified. The intended use of a submit button in this technique is to generate an HTTP request that submits data entered in a form or to perform an action that triggers a change in context, so it is an appropriate control to use to initiate this change.
This is a basic ActionScript 3 example of a combobox component with a submit button to redirect the user to a different resource.
Example Code:
import fl.accessibility.ComboBoxAccImpl;
import flash.net.navigateToURL;
import flash.net.URLRequest;
ComboBoxAccImpl.enableAccessibility();
state_submit.addEventListener(MouseEvent.CLICK, submitHandler);
function submitHandler(e) {
var url: URLRequest = new URLRequest("http://www.wikipedia.org/wiki/" +
state_combo.selectedLabel);
navigateToURL(url, "_self");
}This is a basic ActionScript 2 example of a combobox component with a submit button to redirect the user to a different resource - the same example as in example 1 except in ActionScript 2:
Example Code:
import fl.accessibility.ComboBoxAccImpl;
ComboBoxAccImpl.enableAccessibility();
state_submit.addEventListener("click", submitHandler);
function submitHandler(e) {
getURL("http://www.wikipedia.org/wiki/" + state_combo.selectedLabel, "_self");
}Find all interactive control instances (that are not submit buttons) in the flash movie that can initiate a change of context, e.g. a combobox, radio button or checkbox.
For each instance, confirm that the event handler(s) responsible for the change of context are not associated with the controls themselves, but with a separate button instead.
#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.
