Deprecated Jquery code in the minified version of `jquery-ui`

jquery-migrate-3.5.0 warns of the usage of the subsequent deprecated code in the minified version of jquery-ui (the links have been obscured for privacy consideration):

Notice that when running this with the non-minified version no warning is issued.

By minifying autonomously jquery-ui.js the problem was solved (no warnings by the jquery-migrate tool). Could it be that the file jquery-ui.min.js of the official release does not correspond to the minified version of jquery-ui.js?

[mgol]

Which version of jQuery UI and where are you getting it from?

[mgol]

Also, what version of jQuery do you use? If an old one, some Migrate warnings are expected.

[carlolalu]

This was happening in the process of updating jquery and jquery-ui to their last stable versions (3.7.1 and 1.13 respectively), and jquery-migrate-3.5.0 was used in combination with them to spot any errors/warnings. The migrate tool did not warn of any issues in the uncompressed version, but it did in the minified version of jquery-ui (taken from the zip file downloaded on the official website).

It is worthy of notice that this did not happen with jquery-migrate-3.4.1 and that jquery-migrate-3.5.0 has been released a coupe of weeks ago, so maybe the team responsible jquery-ui is still working on it.

[mgol]

Which 1.13 UI version? Please be specific.

Can you check the behavior with jQuery 3.7.1, jQuery UI 1.13.3 & jQuery Migrate 3.5.2?

Also, you mention the difference between using the minified version of jQuery UI or the unminified one. Which versions of jQuery & jQuery Migrate are you using in both cases: minified or unminified?

[mgol]

Please also double-check your setup. There are no differences between Migrate 3.4.1 & 3.5.0 that would explain such a difference; see the 3.5.0 release notes: https://github.com/jquery/jquery-migrate/releases/tag/3.5.0.

[carlolalu]

You are right, I did not check the usage of jquery-migrate-3.4.1.js together with the minified file jquery-ui.min.js but only with the uncompressed development version file jquery-ui.js. Still I am sure of the problem encountered with jquery-migrate3.5.0 and the file jquery-ui.min.js, at least at the time of opening the issue.

PS: thank you!

[mgol]

Please answer all my other questions, I cannot really do anything without those answers.

My setup had jquery 3.7.1 (non minified) and jquery-migrate 3.5.0 (not minified).

The problem was present with the officially shipped jquery-ui.min.js (thus from the website https://jqueryui.com/ by clicking on the button 'Custom Download') where the jquery-ui custom version 1.13.1 included the all macro sections but the one Effects and the with the theme Smoothness.

I encountered no issues with the non-minified version jquery-ui.js of JqueryUI with the same characteristics as above, thus I minified such file myself and still had no warnings from jquery-migrate. Because of this and because of the lack of big changes in https://github.com/jquery/jquery-migrate/releases/tag/3.5.0 it could have been that the problem was in the lack of correspondence between jquery-ui.js and its officially minified version jquery-ui.min.js, meaning that jquery-ui.min.js could have been the minification of some older version of jquery-ui.js and not the 1.13.1, but that is only an hypothesis.

Unluckily I cannot retry the problem with the new versions you asked me because the code is not anymore available to me. Thank you anyway for your availability, I hope my answer is at least a bit helpful.

I've just downloaded jQuery UI 1.13.3 via the Custom Download link, selecting the modules you described but the versions look correct. In both files, the only mention of jQuery.expr[':'] is in a conditional definition of jQuery.expr.pseudos for jQuery 1.9 or older.

There's also no mention of unbind in the entire minified file. jQuery has stopped using deprecated event shorthands long ago.

I cannot really do more here; I can't even be sure if there was really an issue on our side or if it's something specific to your setup, but I cannot reproduce it.

If you provide very specific steps to reproduce the warnings you posted in the initial post, I can try it, but without it, that's the end of the road for me. Ideally, a simple test case that I can just open & see the warnings immediately.

I'm going to close the issue for now since I don't see anything actionable for us here. You can still post updates here. If you add a reproducible example that I can run and the issue is on our side, I'll reopen.
