jQuery.isFunction is removed in jQuery 4.0+

Thanks for the report. If the resolution is that very clear I am tagging this "Novice" for the next steps.

Thanks cilefen,

Please see a patch we have used to test this. We haven't run extensive tests but similar changes resolves this issue in other code.

I have created a merge request based on the patch provided by @kevin-oyster in Replace_isFunction()_with_typeof_x_===_'function'.patch → . I have reviewed and tested the changes in a Drupal 11 environment, and everything is working as expected.

I am marking this as RTBC.

Same, I don't see the isFunction anywhere too.

Wouldn't it make more sense to use the vanilla JS checkValidity() check and do away with the jQuery valid()?

I made a new MR that uses the native Javascript method instead. Here is some documentation on the method I am suggesting.

I tested the last MR and I ran into this issue:

mandclu → changed the visibility of the branch 3512816-checkvalidity to hidden.

Right, $form at that point is really a jQuery object. There would need to be a much more significant rewrite to remove the dependency here on jQuery.

Moving this back to RTBC on the previous MR.
