Update jQuery step three

[azaozz]

Follow up from #37110 and #50564.

Remove jQuery Migrate 3.3.x.

This ticket represents step 3 in the following roadmap for updating jQuery to 3.x in Core: ​https://make.wordpress.org/core/2020/06/29/updating-jquery-version-shipped-with-wordpress/.

[azaozz]

To be able to disable jQuery Migrate, all JQMIGRATE warnings that are outputted to the browser console (when SCRIPT_DEBUG is enabled) will have to be fixed in core, themes and plugins.

This is a very large task that likely will need some workarounds for older and/or unsupported themes and plugins.

A first step would be to fix all of the (old) js in core. At the same time the core js can be updated to use the new features and syntax from jQuery 3.5+.

[mgol]

If you decide to call jQuery.UNSAFE_restoreLegacyHtmlPrefilter() as part of #50564 then the Migrate warnings will include violations related to self-closed tags. Before you remove Migrate, you'll need to remove that call (or you can do it all in one go).

[SergeyBiryukov]

Moving to 5.7, per the linked roadmap.

Trac ticket: https://core.trac.wordpress.org/ticket/51812

This is an initial patch, with many minor adjustments to a wide array of core files.

Updating the jQuery usage in core is something we should get in early, and will also require some upstream patches to libraries used by WordPress (or, in some cases, updates may exist, the initial focus of this PR is the direct use in core).

A fair amount of deprecations that are not addressed in this PR are being thrown by jQuery UI.

The process taken to identify deprecation issues in core has been a manual one, the initial plan here was to merely do some fancy regex search replace commands, but a lot of components built by core are using similar function names and argument parameters, so instead this has been a manual endeavor, and probably should remain so to keep accidentally breaking changes to a minimum during the alpha stage.

In testing, each admin page was visited, and deprecation warnings addressed individually until there were external libraries throwing warnings. Individual interactions on the page are performed (for example on the classic post editor screen, change the publication time, change the post status), although I make no guarantee there's not scenarios where an interaction may have been missed, so would be good to get more eyes involved.

One exception that is in core, but has not been patched up
{{{js
Accessibility mode.
$( window ).on( 'load', function() {

component.setupAccessibleMode();

});
}}}

This is used in the different components under ​`src/js/_enqueues/wp/widets` which are triggering "too late" in some scenarios, and jQuery throws a warning that the load event has already fired by the time the component is initialized.

@Clorith mentions in the Pull Request:

A fair amount of deprecations that are not addressed in this PR are being thrown by jQuery UI.

We discussed this in today's bug scrub, and think it could potentially be a good idea to split the jQuery UI piece into a separate issue.

Great job!

Just a small suggestion: seems it may be better to replace $.trim( var ) with ''.trim( var ) instad of var.toString().trim(). The last would throw an error when var is undefined, both $.trim() and ''.trim() would return an empty string. All browsers since IE10 have that, see ​https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/trim. For multiple uses can even set local version: var trim = ''.trim; at the top, etc. Alternatively can do var = var || '' before using var.toString().

For the way $( window ).on( 'load', is used in the widgets js perhaps may need to look at Document.readyState, see: ​https://developer.mozilla.org/en-US/docs/Web/API/Document/readyState. Seems it was incorrect before the jQuery update but now that throws a warning.

Good catch on the .trim() bit, I half expected it to be validated before it reached the point of trying to use it.

The .on( 'load' bit has likely been wrong for some time as you say, yeah, isn't the readyState technically the same here though, and would still be "too late"? Or am I misreading you perhaps?

...isn't the readyState technically the same

Yeah, document.onreadystatechange can be used instead of "DOM ready", etc. Thinking it can look at the "property" document.readyState. Perhaps something like:

if ( document.readyState === 'complete' ) {
    // Page is fully loaded.
    component.setupAccessibleMode();
} else {
    // Page is still loading.
    $( window ).on( 'load', function() {
        component.setupAccessibleMode();
    });
}

Ahh, I see what you mean then, that does make sense then.

I've patched the widgets to use your suggestion above (it made the most sense right off the bat).

For the toString().trim() section, I chose the option of var = var || '';, as a quick check showed it being the way core has previously done it in another location as well, so sticking to the same made sense.

[hellofromTonya]

@Clorith @azaozz What's left for this ticket to get it merged for pre-Beta 1 testing?

[Clorith]

We'll want to get in the core fixes for deprecations sooner rather than later (did the timeline for 5.7 change, or am I just terrible at keeping track here?)

As for removing jQuery Migrate being enabled by default, I think we will want to move that back one release (to 5.8). I would ideally like to have more stewing time to capture any missed deprecations in core, and give the jQuery UI team a chance to get their deprecation fixes done as well, so that we do not need to build that our selves.

[hellofromTonya]

did the timeline for 5.7 change, or am I just terrible at keeping track here?

Nope, 5.7 timeline hasn't changed. Beta 1 is 2 Feb, ie 2 weeks away.

I would ideally like to have more stewing time to capture any missed deprecations in core, and give the jQuery UI team a chance to get their deprecation fixes done as well, so that we do not need to build that our selves.

Makes sense for the jQuery deprecations.

For those following, the jQuery UI ticket is #52163.

[hellofromTonya]

Replying to Clorith:

We'll want to get in the core fixes for deprecations sooner rather than later

Are these captured in ​PR 812?

[Clorith]

Yes, PR 812 is good to go as a first push. There will very likely be more minor patches needing to go in for this once we get some real testing going and places that were missed are discovered. But we really just need to get it in to start that process (I had hoped for early to be... much earlier than this :/ but it is what it is)

[hellofromTonya]

Agreed. Get it merged. Then monitor for other minor patch needs.

Is anything blocking PR812 from being merged?

[Clorith]

I believe it's on the radar for @SergeyBiryukov (just needs a committer really to give it the once-over and get it in)

[SergeyBiryukov]

Replying to Clorith:

Yes, PR 812 is good to go as a first push.

Thanks for the PR! Just noting it needs a refresh after [49944] / #46872 and [49973] / #52073.

The first three conflicts are fairly easy to resolve (just remove #doaction2), but I'm less sure about the change in js/_enqueues/wp/widgets/text.js. It looks like the change from this PR takes a different approach at fixing the same issue, so we need to decide on the preferred approach. Since [49973] appears to be tested and confirmed, do we still need $( window ).on( 'load', ... ) there? /cc @azaozz

[hellofromTonya]

Adding needs-refresh for resolving the merge conflicts Sergey noted above.

[azaozz]

Replying to SergeyBiryukov:

Since [49973] appears to be tested and confirmed, do we still need $( window ).on( 'load', ... ) there?

Thinking best would be to keep the changes from [49973] as they make sense. Right, they are tested, also looking at #40986 and [40941] it's not clear why this was originally running on $( window ).on( 'load' instead of DOM ready.

[Clorith]

I suspect the reason was to account for different timings of when they were enqueued, if called by plugins or themes in other locations as well?

If that were the case, the readyState check would help account for this, and not cause unexpected behaviors in anything calling them in a strange location, I'll let someone make that judgement call on which is the preferred approach here though.

[SergeyBiryukov]

After some testing, [49973] seems to work as expected for me too, so I guess we can skip that part of the patch for now and get back to it if any follow-up issues are reported.

I have already resolved the other merge conflicts locally and will commit shortly.

[Hareesh Pillai]

While running the QUnit tests, I came across this warning - jQuery.unique is deprecated; use jQuery.uniqueSort. Upon checking, there's an instance of unique() method being used in customize-widgets.js

[Clorith]

@hellofromTonya great question! So this is a bit of an "oddball" to track, since it requires checking for JavaScript notices or errors, but there's a few ways to do this.

One way is actually to use the ​Enable jQuery Migrate Helper plugin, by visiting its settings (found under Tools > jQuery Migrate), you can enable deprecation warnings and logging for WordPress 5.6 or newer, this is great for non-technical users to test and look for warnings around wp-admin, as it will print them on-screen for the user.

If not, using the JavaScript console of your browser is the more technical approach (I mention this second, as not everyone is comfortable in these interfaces. There's a ​support article on diagnosing JavaScript errors which covers how to open and use these.

Now for the actual testing it self, this is kind of wide. One literally has to visit pages in the WordPress backend, and use features, and see if any warnings show up.

The expected behavior is that nothing should have changed form before and after the patch in features or visuals, only that no warnings should be created in the JavaScript console/plugin mentioned above.

@joyously That's because it is calculating a pixel offset based on a percentage, and a warning is now thrown when using offsets without defining the unit as well.

[hellofromTonya]

This ticket is ready to test following the instructions Marius laid out.

The patch has already been committed into the trunk/master.

[SergeyBiryukov]

Replying to Hareesh Pillai:

While running the QUnit tests, I came across this warning - jQuery.unique is deprecated; use jQuery.uniqueSort. Upon checking, there's an instance of unique() method being used in customize-widgets.js

Just noting that the instance in customize-widgets.js appears to be a ​function from Underscore.js and looks correct as is. Changing it to uniqueSort() does not remove the warning in my testing.

The only instances of jQuery.unique() I've found are from jQuery UI, so I think the warning comes from there.

[dariak]

I have executed smoke testing of the WordPress backend by visiting admin pages. I have not encountered deprecation warnings or errors (used both jQuery Migrate plugin and opened console).

[vedjain]

Should we update the description of this ticket to mention that this scopes updating WP for compatibility with jQuery 3.5.1?

Currently, it mentions "Remove jQuery Migrate 3.3.x." and is milestoned for 5.7, which I believe is not correct as per ​https://wordpress.slack.com/archives/C02RQBWTW/p1612204448014300.

[Clorith]

It's still work related to the disabling of jQuery Migrate by default though, keeping it as a blessed task for 5.7 still makes sense, so that the focus on fixing deprecations in core are not lost.

The milestone should then move to 5.8 when we hit RC, so that the focus can shift to getting the last pieces needed for jQuery Migrate in place, and start informing folks for the next cycle.

Patch applied, new PR for future enhancements will follow.

[jeroenrotty]

I was testing the PR and live previewed the TwentyEleven theme and ran into some deprecations. See screenshot:

Edit: same goes for other themes so I'm guessing it's related to the background image functionality rather than theme specifically.

Trac ticket: https://core.trac.wordpress.org/ticket/51812

Further jQuery deprecation resolutions, see trac ticket for history and further details.

[Clorith]

I added ​PR #982 to address the items that @poena discovered. It further modifies the imgareaselect library, which appears unmaintained since 2013 (I see we have previously also made custom edits to this library). I limited the modifications to only reported deprecations and made them in the bundled library file, and appended -wp to the version string header in the file (this is in line with how core also handled the jQuery 1.12 distributions which were custom patched and no longer maintained).

There are various forks of this library, but there are likely also better solutions that could be investigated by now if the plan is to move away from jQuery used by core as part of the long run.

[SergeyBiryukov]

The screenshot from comment:48, for reference.

[Clorith]

The items from comment:48 appear to be the jQuery-UI elements, I see they're all triggering on the customizer where it is loaded up... I'll be updating the plugin to more closely identify if it's cores own files, or libraries (and if so, which library) is causing a deprecation when possible I think, to make this easier for everyone :)

Marking ​PR 982 for commit to move it into the commit workflow for Beta 2 today. Don't want to lose track of this one.

I apparently just can't get enough of this jQuery stuff :)

[hellofromTonya]

Marking ​PR #1032 for commit.

This PR addresses some of the jQuery 3.5 depreciations, though much will need to continue into 5.8 (we're just too close to RC).

For shorthand event deprecations, changes from .eventName() to .on( 'eventName', or when triggering converts to .trigger( 'eventName' ):

• .blur()
• .click()
• .change()
• .focus()
• .keypress()
• .keyup()
• .bind()
• .unbind()
• .unload()
• .submit()

and a few others:

• $.parseJSON to JSON.parse
• jQuery.isFunction() to typeof ... === 'function'

Thanks! Indeed, there are still a few .bind() calls in the plupload/handlers.js file. Would you be interested in working on a patch? The unminified file is located at js/_enqueues/vendor/plupload/handlers.js​.

Remove deprecated jQuery function bind, replace with on, in handlers.js.

Question from today's bug scrub: Wouldn't it be easier to close this ticket and handle specific changes like bind calls replacing in specific tickets?

[markparnell]

Discussed this again in today's bugscrub and the feeling was that this ticket should likely be closed. The jQuery upgrade is complete - any remaining deprecations in Core can be handled on separate tickets.

The jQuery upgrade is complete - any remaining deprecations in Core can be handled on separate tickets.

Just to clarify, this ticket is not only about addressing the remaining deprecations, but also specifically about removing jQuery Migrate 3.3.x, as outlined in the description per the step 3 of the ​roadmap for updating jQuery to 3.x.

Until that is done, the jQuery upgrade is not complete, so the ticket needs to remain on our radar :) I think the latest PR here still needs to be addressed, then the ticket could probably be moved to Future Release until we're confident that jQuery Migrate 3.3.x can be removed.

Happy to address any feedback in my PR to get it moving/merged. Thanks!

In 54495:

External Libraries: Further fix jQuery deprecations in WordPress core.

This replaces calls to the deprecated jQuery .bind() method with .on() in Plupload's handlers.js.

Reference: ​jQuery API Documentation: .bind()

Thanks for the PR! Merged in r54495.

Moving to Future Release for now, this can be put on a release milestone again when there is consensus about removing jQuery Migrate, as per the step 3 of the ​roadmap for updating jQuery to 3.x.

Any chance of getting 3.4.0 as it's just a link change on your side and as jQuery Migrate is still in WordPress?

Or a warning removal:

/*Remove JQuery Migrate warning*/
function remove_jquery_migrate_notice() {
    $m= $GLOBALS['wp_scripts']->registered['jquery-migrate'];
    $m->extra['before'][]='temp_jm_logconsole = window.console.log; window.console.log=null;';
    $m->extra['after'][]='window.console.log=temp_jm_logconsole;';
}
add_action( 'init', 'remove_jquery_migrate_notice', 5 );

Thanks for flagging that! Updating jQuery Migrate to version 3.4.0 is being tracked in #56743.
