With each new browser’s version we found new programming features that let us make more advanced AJAX effects. Even when most of these improvements are present at the major browsers that are more standard every day, there are always many reasons to found different users configurations:

• Users that keep using old browser’s versions.
• Users that use less popular and less standard browsers.
• User that disable javascript or make other restrictions for security reasons.
• Search engine’s spiders that do not use to parse javascript and then some texts can leave hidden.
• Users with accessibility limitations that use other ways to read the pages.

In order to reach all these users we need that those pages that use javascript to make advanced AJAX effects gracefully degrade, that means that the page must be able to work even when javascript or another special features are disabled.

In the next post we will see a real case and how to solve it using Prototype.
