useSubmit

The imperative version of <Form> that lets you, the programmer, submit a form instead of the user.

import { useSubmit } from "@remix-run/react";

function SomeComponent() {
  const submit = useSubmit();
  return (
    <Form
      onChange={(event) => {
        submit(event.currentTarget);
      }}
    />
  );
}

Signature

submit(targetOrData, options);

targetOrData

Can be any of the following:

HTMLFormElement instance

<Form
  onSubmit={(event) => {
    submit(event.currentTarget);
  }}
/>

FormData instance

const formData = new FormData();
formData.append("myKey", "myValue");
submit(formData);

Plain object that will be serialized as FormData

submit({ myKey: "myValue" });

options

Options for the submission, the same as <Form> props. All options are optional.

• action: The href to submit to. Default is the current route path.
• method: The HTTP method to use like POST, default is GET.
• encType: The encoding type to use for the form submission: application/x-www-form-urlencoded or multipart/form-data. Default is url encoded.
• preventScrollReset: Prevents the scroll position from being reset to the top of the window when the data is submitted. Default is false.
• replace: Replaces the current entry in the history stack, instead of pushing the new entry. Default is false.
• relative: Defines relative route resolution behavior. Either "route" (relative to the route hierarchy) or "path" (relative to the URL).

submit(data, {
  action: "",
  method: "post",
  encType: "application/x-www-form-urlencoded",
  preventScrollReset: false,
  replace: false,
  relative: "route",
});
