Reactjs - How to run setSubmitting() outside the submit handler?

In React with Formik, the setSubmitting function is typically used within the submit handler to manage the form submission state. However, there may be scenarios where you need to access setSubmitting outside of the submit handler, such as in response to certain asynchronous operations or events. Here's how you can achieve this:

Using Formik's useFormikContext

Formik provides a hook called useFormikContext that allows you to access the Formik context outside of the form component. This context includes setSubmitting among other Formik state and helpers.

Here's a basic example of how you can use useFormikContext to access setSubmitting and update the form submission state outside of the submit handler:

  1. Import Required Dependencies

    Ensure you have imported necessary dependencies including useFormikContext from Formik.

    import { useFormikContext } from 'formik';

  2. Access setSubmitting Outside of Submit Handler

    You can use useFormikContext hook in any component that is a child of your Formik form component to access setSubmitting.

    import React from 'react'; import { useFormikContext } from 'formik'; const SomeComponent = () => { const { setSubmitting } = useFormikContext(); const handleSomeAction = () => { // Example asynchronous operation (e.g., API call) setSubmitting(true); // Simulate asynchronous operation (e.g., setTimeout) setTimeout(() => { // After completing the operation, reset submitting state setSubmitting(false); }, 2000); // Simulating a 2-second asynchronous operation }; return ( <div> <button onClick={handleSomeAction}>Do Something Async</button> </div> ); }; export default SomeComponent;

Explanation:

  • useFormikContext: This hook allows you to access the Formik context, which includes setSubmitting among other Formik state and helpers.

  • Handling Asynchronous Actions: In the handleSomeAction function, you can perform any asynchronous operation (e.g., API call, setTimeout) and use setSubmitting to control the form submission state.

  • Resetting setSubmitting: After completing the asynchronous operation, you can call setSubmitting(false) to indicate that the submission process is complete.

Notes:

  • Make sure that the component using useFormikContext is rendered as a child of the Formik component. Otherwise, the hook won't have access to the Formik context.

  • Using setSubmitting outside of the submit handler is useful for managing form submission states in response to various asynchronous events or operations within your application.

By following this approach, you can effectively manage the submission state of your Formik forms in React, even outside of the typical submit handler context. Adjust the example code according to your specific use case and application requirements.

Examples

  1. ReactJS: How to use setSubmitting outside Formik submit handler?

    • Description: Use Formik's setSubmitting outside the submit handler to manually set the form's submitting state.
    • Code:
      import React from 'react'; import { Formik, Form, Field } from 'formik'; const MyForm = () => ( <Formik initialValues={{ name: '' }} onSubmit={(values, { setSubmitting }) => { setTimeout(() => { alert(JSON.stringify(values, null, 2)); setSubmitting(false); }, 400); }} > {({ isSubmitting, setSubmitting }) => ( <Form> <Field type="text" name="name" /> <button type="submit" disabled={isSubmitting}> Submit </button> <button type="button" onClick={() => setSubmitting(false)} > Set Submitting False </button> </Form> )} </Formik> ); export default MyForm;

  2. ReactJS: Formik setSubmitting from outside the form component

    • Description: Access Formik's setSubmitting from a parent or another component.
    • Code:
      import React, { useRef } from 'react'; import { Formik, Form, Field } from 'formik'; const MyForm = ({ formikRef }) => ( <Formik innerRef={formikRef} initialValues={{ name: '' }} onSubmit={(values, { setSubmitting }) => { setTimeout(() => { alert(JSON.stringify(values, null, 2)); setSubmitting(false); }, 400); }} > {({ isSubmitting }) => ( <Form> <Field type="text" name="name" /> <button type="submit" disabled={isSubmitting}> Submit </button> </Form> )} </Formik> ); const ParentComponent = () => { const formikRef = useRef(); return ( <div> <MyForm formikRef={formikRef} /> <button onClick={() => formikRef.current.setSubmitting(false)} > Set Submitting False </button> </div> ); }; export default ParentComponent;

  3. ReactJS: Call Formik's setSubmitting from an async function

    • Description: Use setSubmitting in an async function outside the submit handler.
    • Code:
      import React, { useRef } from 'react'; import { Formik, Form, Field } from 'formik'; const MyForm = ({ formikRef }) => ( <Formik innerRef={formikRef} initialValues={{ name: '' }} onSubmit={async (values, { setSubmitting }) => { try { await new Promise(resolve => setTimeout(resolve, 1000)); alert(JSON.stringify(values, null, 2)); } finally { setSubmitting(false); } }} > {({ isSubmitting }) => ( <Form> <Field type="text" name="name" /> <button type="submit" disabled={isSubmitting}> Submit </button> </Form> )} </Formik> ); const ParentComponent = () => { const formikRef = useRef(); const handleButtonClick = async () => { // Simulate an async operation await new Promise(resolve => setTimeout(resolve, 500)); formikRef.current.setSubmitting(false); }; return ( <div> <MyForm formikRef={formikRef} /> <button onClick={handleButtonClick}> Set Submitting False </button> </div> ); }; export default ParentComponent;

  4. ReactJS: Using setSubmitting in Formik with custom hooks

    • Description: Implement a custom hook to use setSubmitting outside the submit handler.
    • Code:
      import React, { useRef, useCallback } from 'react'; import { Formik, Form, Field } from 'formik'; const useFormikSubmit = () => { const formikRef = useRef(null); const setSubmitting = useCallback((isSubmitting) => { if (formikRef.current) { formikRef.current.setSubmitting(isSubmitting); } }, []); return { formikRef, setSubmitting }; }; const MyForm = ({ formikRef }) => ( <Formik innerRef={formikRef} initialValues={{ name: '' }} onSubmit={(values, { setSubmitting }) => { setTimeout(() => { alert(JSON.stringify(values, null, 2)); setSubmitting(false); }, 400); }} > {({ isSubmitting }) => ( <Form> <Field type="text" name="name" /> <button type="submit" disabled={isSubmitting}> Submit </button> </Form> )} </Formik> ); const ParentComponent = () => { const { formikRef, setSubmitting } = useFormikSubmit(); return ( <div> <MyForm formikRef={formikRef} /> <button onClick={() => setSubmitting(false)} > Set Submitting False </button> </div> ); }; export default ParentComponent;
