Double clicking update on list table inline edit removes row from dom

[mt8.biz]

Steps to reproduce:
Open "Quick Edit" -> Save the category(or tag) by double-click on save-button. ( or press twice ).

Expected behaviour:
Save the category(or tag) , and refresh the table-row.

Actual behaviour:
Save the category(or tag), But disappear the table-row.

Confirmed for 3.8-alpha. Only happens when double clicking.

I can reproduce in 3.6.1 On all List Tables that have quick edit. This is a result of how closures work in javascript and can be explained better here ​http://stackoverflow.com/a/10152046.

Maybe disabling the update button when the first click event fires?

Closed #25573 (posts) and #25606 (comments), as this ticket seems to have attracted more eyes. Suggest working on a generalized solution, even if it has to go into multiple files.

Changes to inline-edit-tax.js and inline-edit-post.js.

Thanks For Manage Tickets. ( And Patch To English. )

Do you have problems with my patch?

[mt8.biz]

Changes to edit-comments.js .

I was referring to the patch of shanept.

Thanks.

[mt8.biz]

some fix.

I'd propose a new approach, similar to what is used in heartbeat.js (actually heartbeat.js has two ways to handle this). Basically aborting the AJAX request if any previous one has not completed yet would solve the double click (and double Enter) issue. The same approach can be used to fix #12769.

The attached patch is for testing only for now, and focuses only on inline-edit-post.js. If OK, the same thing should be done for inline-edit-tax.js. Have to check comments yet.

Any feedback would be greatly appreciated, cc @azaozz :)

Note: the simpler way to reproduce this is:

• Quick Edit a post
• place the cursor on any input field or textarea, focus a select or check a checkbox
• quickly press "Enter" twice
• after saving, the Quick Edit form closes and the table row disappears

This sounds like a good approach, as this is something we already do in other cases (e.g. Publish button on the Edit Post page is disabled after click and during autosaves).

Disabling buttons is problematic for keyboard users since the buttons will be focused and then disabled, causing a focus loss.

Good to know! Should button disabling be considered an anti-pattern for that reason?

It always depends, case by case. But when disabling, hiding, removing from the DOM, a focused element then focus should be moved to the most logical place. Better: avoid a focus loss in the first place :)
Also, the Quick Edit form can be submitted pressing Enter on any field (also the textarea, select, checkboxes) so I'm not sure disabling the button would really solve the issue.

25696.patch is a good start. Think we will need to abort the request when the users click Cancel so if they click on another Quick Edit it won't block it.

We also may need better "busy" indication. Clicking on another Quick Edit while the request hasn't been completed yet or had some sort of error is frustrating: nothing happens. Wondering if we should be showing wait or progress cursor?

[azaozz]

In 25696.2.patch: also add xhr.abort() when the user clicks Cancel.

[afercia]

Refreshed patch, taking care also of Terms and Comments. Some notes:

• when saving maybe it should just return false instead of using xhr.abort()
• should users be allowed to open a new Quick Edit form while a previous request has not completed yet? this would be easy to restore, not sure if safe
• removed the toggle function, it was used to open the form on double click, seems no more used since [9439] and removed in [9726] unless I'm missing something
• the parameter passed to save() and edit() is always a DOM object so calling it id is a bit confusing

Clicking on another Quick Edit while the request hasn't been completed yet or had some sort of error is frustrating: nothing happens.

Yep, see point 2. Currently, clicking to open a new form won't do anything, see below:

Theoretically, the whole thing could be refactored in order to allow a row to be updated "in the background" when it's closed because users clicked on a new Quick Edit link. Not sure it would be so safe and easy to implement :)

[afercia]

To recap: the patch still applies cleanly, needs a decision about this point:

should users be allowed to open a new Quick Edit form while a previous request has not completed yet?

in response to:

Note: this should fix also #12769.

@irozum Thanks for the review. I added the requested @property {boolean} saving entry to the top-level inlineEditPost namespace docblock and pushed it in commit 3e3dcd3e73.

[arkaprabhachowdhury]

Opened [PR #12869](​https://github.com/WordPress/wordpress-develop/pull/12869) to address this ticket. It prevents duplicate Quick Edit save requests for posts and taxonomies while an AJAX request is active, clears the guard when the request completes—including failed requests—and adds QUnit coverage for both editors.

I picked this up because the ticket’s double-click reproduction still maps to a current client-side race: the first response removes the inline-edit row, while the second response then operates on missing markup. This PR is submitted for code review, with the existing ticket discussion remaining here.
