Update to latest jQuery and UI

[hebbet]

jQuery 1.6.2 was released today.

​http://blog.jquery.com/2011/06/30/jquery-162-released/

maybe for 3.2.1

We'll drop this into trunk right after we branch. If things don't break then 3.2.1 is possible.

The update to jQuery 1.6.1 brought quite a few plugin/theme issues despite that we did everything possible to warn plugin and theme authors. Perhaps we should update both jQuery and UI in August and stick with them for 3.3.

related: #17474

Closed #17474 as duplicate.

Replying to jczorkmid:

For compatibility's sake this is a good idea. Was hoping we would move away from UI in core as we mostly use it for drag+drop support and there are lighter jQuery plugins for this.

However it seems many WordPress plugins and themes will continue to use UI, so adding the whole UI to core will make it easier for them. The only "against" would be the increase of the total download size of WP.

On the other hand we probably could un-bundle Prototype.js as very few plugins seem to use it. Perhaps we can leave it in script-loader but load it from Google.

Should I attach the jQuery UI patch to this ticket so it doesn't get lost in the shuffle?

Replying to jczorkmid:

No need, whoever commits this can grab the latest version from the UI website if there's one or use the patch from #17474.

Ok, thanks. Hopefully they won't just grab the latest. ​The patch also added the remainder of the UI libraries to wp-includes/script-loader.php. :)

errrrrrrr

jQuery UI 1.8.15
​http://blog.jqueryui.com/2011/08/jquery-ui-1-8-15/

jQuery UI version 1.8.16
​http://blog.jqueryui.com/2011/08/jquery-ui-1-8-16/

jQuery 1.6.3 ...

I updated WP for use jQueryUI >= 1.8.13 and an error occurred when using a new widget in the sidebar.

In wp-admin/js/widgets.js, line 113:

var add = ui.item.find('input.add_new').val(),
    n = ui.item.find('input.multi_number').val(),
    id = ui.item.attr('id'),
    sb = $(this).attr('id');

'id' is undefined, because it was removed from ui.item

Replying to marcelometal:

Yes, this is a regression. Still wondering what's better: patch that and update to 1.8.16 or keep 1.8.12. Opened a ticket on UI's trac: ​http://bugs.jqueryui.com/ticket/7734

Would rather patch and update to 1.8.16, but still track this upstream. Thanks for submitting.

In [18757]:

Update jQuery to 1.6.4, update jQuery UI to 1.8.16, add the rest of UI, add workaround for a regression in UI Draggable, see #17952

Replying to nacin:

Yes, added a workaround for that, preferable to changing it. Hopefully it will not break anything else as combining Draggable with a Sortable is not common.

Glad to see the full jQuery UI library rolled in.

In [18774]:

Fix the workaround for UI Draggable to include single instance widgets (do they still exist?), see #17952

Replying to azaozz:
single instance widgets (do they still exist?)

They're all over the place, for sure.

Akismet even still uses them.

In [18795]:

Correct the src for jquery-ui-datepicker. props danielbachhuber, fixes #18793. see #17952.

Resolving as fixed. We can open a new ticket if and when the jui regression is addressed upstream.

Nothing.
