*error handling – There is onError event function !

*(much) more animations – Ajaxify uses jquery animate function. which can animate almost any CSS property. (Much more than cba)

*easier implementation, especially for larges sites. – Ajaxify can run with only one line $(jquery_selector).ajaxify();

*custom errors & states (Again as 1st one)

I’m not sure from other points. but there is also options that cba doesn’t have too.

* tagToLoad
*Manipulation
*Overriding Default settings
*Can bind any event to the object.
*Title
*Not limited to
*Easy to define the objects through jQuery selectors.
*Compatible with other jQuery plugins.
*And ajaxify is just 10 kb where cba is around 40kb

These are the problems that are mentioned on that page:
* Slower than the traditional way ( com.bydust.ajax class is faster than normal browsing )
* No feedback – loading bars unavailable. ( com.bydust.ajax gives feedback, loading, parsing and preloading states )
* Breaks the Back button. (cba does not break the previous and next browser buttons )
* Users have no clue on which page they actually are – so they won’t be able to bookmark the page. (cba allows user to bookmark the correct page )
* Users will think that nothing is happening – when they click on the link and nothing happens. ( cba shows states. When the users’ browser does not meet the requirements the site is being handled by the browser )
* And More…

this probably applies to this script too, not only cba

the com.bydust.ajax class has:
- error handling
- (much) more animations
- better eventlisteners
– user can edit the retrieved content
– user can see status messages
– when a second eventlistener is added on the same event the first one isn’t removed.
- easier implementation, especially for larges sites.
- custom errors & states
- rules for forms and url’s
- etc…

This script has alot more options and is more customizable: http://www.bydust.com/examples/com.bydust.ajax/
