React Hook Form: Issues with Updating Dependent Fields on Select Change
I'm reviewing some code and I recently switched to I'm testing a new approach and Can someone help me understand I'm having a hard time understanding I'm encountering a problem with React Hook Form where the values of dependent fields are not updating correctly when a selection changes in a dropdown. I'm using version 7 of React Hook Form along with a controlled component for my select inputs. Here's a snippet of my code: ```javascript import React from 'react'; import { useForm, Controller } from 'react-hook-form'; const MyForm = () => { const { control, watch, setValue } = useForm(); const selectedOption = watch('option'); const handleOptionChange = (value) => { setValue('dependentField', value === 'option1' ? 'valueA' : 'valueB'); }; return ( <form> <Controller name="option" control={control} defaultValue="option1" render={({ field }) => ( <select {...field} onChange={(e) => { field.onChange(e); handleOptionChange(e.target.value); }}> <option value="option1">Option 1</option> <option value="option2">Option 2</option> </select> )} /> <Controller name="dependentField" control={control} render={({ field }) => <input {...field} />} /> </form> ); }; ``` The `dependentField` should update automatically based on the selection from the dropdown. However, when I change the option, it does not seem to reflect the expected value in `dependentField`. Instead, it shows the last value that was manually entered into that input before the change. I've also checked the console and confirmed that `handleOptionChange` is being called correctly. I tried using `useEffect` to watch changes to `selectedOption`, but that didn't yield any results either. Here’s what I attempted: ```javascript useEffect(() => { setValue('dependentField', selectedOption === 'option1' ? 'valueA' : 'valueB'); }, [selectedOption]); ``` But this approach still does not update the input as expected. The input field remains unchanged unless I manually edit it. Any guidance on how to resolve this issue would be greatly appreciated! For context: I'm using Javascript on Linux. What's the best practice here? I'm working on a application that needs to handle this. Any feedback is welcome! My development environment is macOS. I'd love to hear your thoughts on this. What's the best practice here? I'm on CentOS using the latest version of Javascript. Am I missing something obvious?
