FormAdvance Field Array import React from "react"; import { useForm } from "react-hook-form"; function App() { const { register, watch, formState: { errors }, handleSubmit } = useForm(); const watchShowAge = watch("showAge", false); // you can supply default value as second arg...
使用DOM方法： getElementById() getElementsByTagName() getAttribute() setAttribute(...
