Nominating ticket for 1.7 discussion.

+1,

+0, I suggests this but I have no firm conviction regarding it... hence why I ask you guys

+1,

+1, This is a quick deprecation, we shouldn't have added it. But I agree it's a mess to retain it, let's document it immediately but leave it in for a while.

-1, Doesn't make sense to me that users should have to use the word "success" if they're using an options object to $.ajax but .done if they're subscribing to the $.ajax Deferred-style. (Same for error/fail)

+1, please please please

-1, the name success is all over the place for ajax, we should keep these

Docs updated: http://api.jquery.com/jQuery.ajax/

This is documented as deprecated already so I'll consider this fixed... unless we wanna keep track of this for removal in 1.8?

Where can I find information about - why - these got deprecated?

Where can I find information about - why - these got deprecated?

Not only why, but why the documentation examples still use success, error, and complete. Deprecating this is 1.7 and removing in 1.8 doesn't give enough time. These shouldn't be removed until at 1.9 or later. Or at the very least, alias success, error, and complete to done, fail, always for backwards compatibility.

Absolutely concur with commentor 18. The success, error,and complete handlers should be aliased for backward compatibility for an extended period, if not indefinitely. I shudder to imagine the number of unhappy users which would be uncovered by their removal.

Don't go changing names just because you don't like them.

Docs updated?! The page does not even have these new names in main settings list. Some obscure mention in a semi-random place is not enough. To say the truth whole page is rather incomprehensible, so could be you were just following tradition.

That's because the 'settings' options have not and will not change, only the $.ajax().success() $.ajax().error() etc, aliases to done, fail, always, which will be available in 1.7 and deprecated in 1.8. This is a relatively new API anyway (1.5) and keeping these aliases around in perpetuity is unwise.

Yay, this will only break ALL MY WEBSITES!

@ajpiano Is there a roadmap for when the removal of these methods are planned to take place?

Upon removal, could we release a compatibility plugin to re-alias these for people who don't understand how that would work themselves? Shouldn't be too difficult...

I agree we could do a better job at publicizing the logic behind these changes, and we will in the future.

Note that this change isn't intended to remove any functionality, it just removes the aliases that we put on the Deferred object returned by $.ajax so that it uses the standard Deferred names. It should be possible to move to the new names via a simple text replace in most cases.

@eli, no there is not a roadmap for removal in general. We are deprecating things to indicate that they are not the best-practice way to do something in jQuery. It's possible that things that are deprecated are *never* removed, but then again we are unlikely to add features to it or fix bugs in a feature like that.

success, error,and complete handlers should be aliased for backward compatibility for an extended period, if not indefinitely

Agreed about the extended period. Note, however, that even if we wait five years there will be people who have not changed their code. Deprecation is the start of the notice we need to give if we are ever to have a hope of removing something.

In the meantime, nothing prevents anyone from using the features marked deprecated in 1.7, including this one. We will start a separate (and more visible) thread about the direction of jQuery once 1.7 has shipped.

could we release a compatibility plugin

That has been suggested and would most likely be our approach for many of these things in the 2.0 time frame.

I think the document should clearly indicate the $.ajax() option names of success etc are not changed. I got the impression that they may also changed reading the 1.7 docs, and couldn't find clear answers in the doc itself.

This deprecation notice is being moved to 1.8, since the docs indicated it was to start then despite this ticket.

The reason these were deprecated is that they create an unneeded special case for the Deferred returned from an XHR.

This change does not include the $.get and $.post methods, right?
