Technologies that have event handlers specific to pointing devices.
User Agent and Assistive Technology Support Notes
None listed.
This failure relates to:
When pointing device-specific event handlers are the only mechanism available to invoke a function of the content, users with no vision (who cannot use devices such as mice that require eye-hand coordination) as well as users who must use alternate keyboards or input devices that act as keyboard emulators will be unable to access the function of the content.
The following example is of an image that responds to a mouse click
to go to another page. This is a failure because the keyboard cannot
be used to move to the next page.
<p><img onmousedown="nextPage();" src="nextarrow.gif"
alt="Go to next page"></p>
Resources are for information purposes only, no endorsement implied.
Check to see whether pointing-device-specific event handlers are the only means to invoke scripting functions.
If any are found, then this failure condition applies and content fails the Success Criterion.
Techniques are informative—that means they are not required. The basis for determining conformance to WCAG 2.0 is the success criteria from the WCAG 2.0 standard—not the techniques.
