Question

Is there a way to have a button function as a submit button for a form even when it is located in a separate component within a react application?

I am in the process of creating a user-friendly "My Account" page using react, where users can easily update their account information. I have divided my components into two sections: the navbar and the form itself. However, I am facing an issue with the submit button for the form being located in the navbar component, while the actual form is within the accountdetails component. Both components share a common parent component (App.js). How can I make the edit button in the top right corner of the screen function as a submit button for the form, ensuring that all form validations are met to prevent users from submitting incorrect data?

If you want to trigger form submission programmatically, one way is to create an invisible submit button in the form component and pass a reference to it from your App.js file. Then, in your App.js, you can set up a function that clicks this invisible button when needed. This function can be passed to another visible button on the navbar for easy triggering. Check out the example below:

App.js

...
export default App = () => {
    const submitButtonRef = useRef(null);
    
    const submitForm = () => {
        if (submitButtonRef) {
            submitButtonRef.current.click();
        }
    }
    
    return (
        ...
            <Navbar submitForm={submitForm} />
            <FormComponent submitButtonRef={submitButtonRef} />
        ...
    )
}

Navbar component

...
export default Navbar = ({submitForm}) => {

    return (
       ...
            <button onClick={() => submitForm()}>Submit</button
        ...
    )

Form component

...
export default FormComponent = ({submitButtonRef}) => {

    return (
        ...
           <button 
                style={{display: "none"}} 
                htmlType="submit" 
                ref={submitButtonRef}
            >
                Submit
            </button>
        ...
    )

I'm still learning, so any feedback or suggestions are greatly appreciated. Thank you!
