Form Submit

The form_submit component is Vue.js driven child component of the form component and is used to trigger the parent form to submit its data.

form my_form_config do
  #...
  form_submit do
    button text: "submit"
  end
end

All child components form_* (including this component) have to be placed within the scope of the parent form component, without any other Vue.js driven component like toggle, async creating a new scope between the child component and the parent form component! Non-Vue.js component can be placed between form and form_* without issues!

# that's working:
form some_form_config do
  form_* key: :foo
  toggle show_on: "some-event" do
    plain "hello!"
  end
end

# that's not working:
form some_form_config do
  toggle show_on: "some-event" do
    form_* key: :foo
  end
end

Parameters

form_submit does not take any parameters but yields a given block. This block will be wrapped by a span tag. A click on that span tag and all elements within will submit the form.

Loading state

If you simply want to disable your submit button, you can use a simple Vue.js binding:

form_submit do
  button text: "Submit me!", attributes: { "v-bind:disabled": "loading()" }
end

If you want to adjust the submit element more flexible while the form is being submitted, you could use the event mechanism of the form in combination with the toggle component:

form_submit do
  toggle hide_on: "form_loading", show_on: "form_succeeded, form_failed", init_show: true do
    button text: "Submit me!"
  end
  toggle show_on: "form_loading", hide_on: "form_succeeded, form_failed" do
    button text: "submitting...", disabled: true
  end
end

in combination with a form config like this:

def my_form_config
  {
    #...
    emit: "form_loading",
    success: {
      emit: "form_succeeded"
    },
    failure: {
      emit: "form_failed"
    }
  }
end
