$.ajax promise cannot be piped with a failFilter only

[[email protected]…]

request = $.ajax({url: '/'}).pipe( null, handleError )

I'd expect that the request would be the original promise returned by $.ajax, but the abort method does not exist anymore. Is this a bug or by design? Any suggestion on how to work around it in an elegant manner?

Both version are affected, 2.0.3 as well as 1.9.1

The result of a .pipe() is a new Deferred, not the original jQXHR, so it doesn't have an .abort() method. Save the result of $.ajax() if you need to abort.

FWIW I've made a little library to make our lives easier if you want to retain properties across piped deferreds: ​https://github.com/onyxrev/jquery_promiscuous_deferred
