Add "form" attribute to buttons of type="submit"

[undavide]

🙋 Feature Request

It would be nice to have a "form" attribute for React Spectrum Buttons, when they are of type="submit".

🔦 Context

See the following example coming from the React Spectrum examples page:

<DialogTrigger>
  <ActionButton>Register</ActionButton>
  {(close) => (
    <Dialog>
      <Heading>
        <Flex alignItems="center" gap="size-100">
          <Book size="S" />
          <Text>Register for newsletter</Text>
        </Flex>
      </Heading>
      <Header>
        <Link>
          <a href="//example.com" target="_blank">
            What is this?
          </a>
        </Link>
      </Header>
      <Divider />
      <Content>
        <Form>
          <TextField label="First Name" placeholder="John" autoFocus />
          <TextField label="Last Name" placeholder="Smith" />
          <TextField label="Street Address" placeholder="123 Any Street" />
          <TextField label="City" placeholder="San Francisco" />
        </Form>
      </Content>
      <Footer>
        <Checkbox>
          I want to receive updates for exclusive offers in my area.
        </Checkbox>
      </Footer>
      <ButtonGroup>
        <Button variant="secondary" onPress={close}>
          Cancel
        </Button>
        <Button variant="cta" onPress={close}>
          Register
        </Button>
      </ButtonGroup>
    </Dialog>
  )}
</DialogTrigger>

The dialog is nicely designed, and the content is kept separate in the <Heading>, <Content>, and <Footer>.

Problem is that the ButtonGroup, which very likely contains a submit button in such Dialogs, belongs to the Footer, i.e. it's not contained within the <Form> component – hence it can't act as a Button of type="submit".

In HTML it's possible to add a form attribute to a submit Button, so that it can work regardless to its positioning. E.g.

<form id="aForm">
  <!-- stuff -->
</form>
<button type="submit" form="aForm">Submit</button>

A similar possibility for <Form> and React Buttons would be nice to have.

Thanks!

@undavide Allowing the form attribute on a button seems pretty reasonable, lemme double check with the team just in case.

I'm guessing this is related to wanting the enter key to trigger the submit button's action? I'm having a hard time imagining wanting to submit a form in a dialog via the browser which would trigger a full page reload.

If so, it seems related to #855

[undavide]

Uhm, actually no, my feat request was specifically only about being able to use a submit button when the button itself can't be inside the <form>

[razvanip]

i think there are some other libraries out there regarding forms that usually really on a submit button being present in the form to handle submit

[dmbaughman]

Since the <Button> component in Spectrum is an implementation of the native <button> element, shouldn't it support all the native attributes?

I have a similar use case where I was trying to put a form inside the content area of a dialog, and then include a submit button in the footer of the dialog, because wrapping the input and submit buttons in the same <Form> component was breaking the dialog layout.

I think Button should also have name, value, formmethod and formaction attributes. They are all very useful when working with forms. And in frameworks like remix-run forms are used to trigger any actions (they do not trigger full reloads like it was mentioned earlier). In some cases this approach makes it simpler to implement a basic experience even if JavaScript fails for some reason.

I'm struggling with the same Issue. My very ugly workaround right now is to add

  useEffect(() => {
    ref.current?.UNSAFE_getDOMNode().setAttribute("form", "new-field-form");
  }, [ref]);

I've also run into this issue. I have a situation where I'm trying to deal with a nested form. The natural conclusion is instead to have self-closing forms with ids that the inputs then refer to. This doesn't seem possible to do with react-spectrum.

As outlined in #6481, I think this is a very important issue, as this would be universally applicable & areas of application are manifold. The Dialog modal component is perfect for submitting any kind of form data, and as @undavide pointed out, the great default design should not be compromised in order to achieve something like that - up to now, I put ButtonGroup inside Content and added the margin etc myself, having to integrate Footer manually, and well .. sigh

Beware though that we'd need a solution which takes into account not only Content, but also eg Footer (see the checkbox in OP's example) 🙏
