1194.22 (l) Write Accessible Scripts

When pages utilize scripting languages to display content, or to create interface elements, the information provided by the script shall be identified with functional text that can be read by assistive technology.

One way to check your site for Section 508 compliance on this standard is to be sure essential information is not lost when JavaScript functions are turned off. If you use mouse-over highlighting or if there are alternatives for the links in your mouse-over menus, essential information will not be lost.

If you use scripting to write essential information in visible form when your document is loading, then that information will be available to assistive technology.

If you are using hidden content exposed with JavaScript event handlers, make sure that either equivalents are available without JavaScript or that you can trigger the event handlers with the keyboard.
