Submit Without Reload

A comment form, a search box, a quick-add field — submit without losing scroll position or context. The server processes it and returns a snippet (confirmation text, rendered item, status message) that appears right below the form.

Put data-fui-rpc on a <form> element. The runtime intercepts the submit, POSTs fields as JSON, and writes the response into the signal. Add data-fui-rpc-reset to clear the form after success so the user can submit again.

interactive.OnSubmit(
    render.Tag("form", nil,
        render.Tag("input", map[string]string{"name": "body", "required": ""}),
        render.Tag("button", map[string]string{"type": "submit"}, render.Text("Post")),
    ),
    interactive.Post("/api/comment").
        OnSuccess(
            interactive.SetSignal("comment-result"),
            interactive.ResetForm(),
        ),
)
