jquery not working on some forms

-- HikaShop version -- : 4.3.0

Hello
using Joomla 3.9.19 and Hikashop Starter 4.3.0

I need to add pieces of jquery to address forms (e.g. in order to change background-color of firstname inputbox when focused), but sometimes - e.g.when openining the form via Usercontrol panel - it seems not to be possible, nothing happens.
Does it depend on something concerning ajax? Is there a way to bypass the problem?
Thank you very much

Hi,

That's probably because if you add your javascript code to the form view file it is not being processed when the interface is being loaded in AJAX. I suppose because you have your code wrapped in jquery.ready ( learn.jquery.com/using-jquery-core/document-ready/ ) which isn't called when the JS is run after the AJAX.
If you edit the file address / listing.php via the menu Display>Views, you'll see many times the line: In each places, you can call your own code after the interface is being refreshed in AJAX.

Thank you for your prompt reply, Nicolas.
I took a look to listing.php and sow, but sorry I'm not so handy with ajax: would you give me a little example? Something like a js alert when clicking on firstname textbox or something similar?
Thanks so much

I mean also: where have I to put the code?

Hi,

Just put alert('test1'); and alert('test 2'); etc after each t.loading(false); and you'll see see where you need to add your javascript code based on which alert is displayed when you're on the area with the issue you have.

Got it! Thank you Nicolas, I'm very grateful.
