[4.0] Radio button onchange form submit did not work in joomla filter bar

[HRIT-Florian]

Steps to reproduce the issue

1. Edit administrator\components\com_content\forms\filter_articles.xml
2. Add a radio button form field like

<field
  name="text"
  type="radio"
  onchange="this.form.submit();"
  default="0"
>
	<option value="0">JNO</option>
	<option value="1">JYES</option>
</field>

3. Go to administrator/index.php?option=com_content&view=articles and try to toggle that radio button

Expected result

onchange="this.form.submit();" should submit the form and the toggled radio button should be selected

Actual result

nothing happens, js event did trigger

System information (as much as possible)

Looking at the code, onchange should be added to each individual option like this:

<option value="0" onchange="this.form.submit();">JNO</option>

It's the same in J3. But different for switcher layout in J4.

Yeah, did work by adding to option, but thats not clear and too much if you have a large list of options.
Anyway thanks for that info, but someone should fix it.

[SharkyKZ]

Well, there's an advantage to having this on options - each option can have a different onchange value.

[HRIT-Florian]

I don't think it's an advantage. It should be possible to set the handling onchange for all fields equally. If someone else wants to handle it different, he can write a separate field for it.

As @SharkyKZ pointed out, you can add onchange to individual option. From documentation of our radio form field, onchange is not a supported attribute too. For the time being, it is not really an issue, I'm converting it to discussion and we can discuss further from there if needed.
