[英]react-hook-form - how to reset formState.isDirty after form submitting
[英]React Hook Form - formState is not defined
我正在尝试在我的 react 应用程序中使用 React-Hook-Forms,并且我使用的是 react-hook-form 版本 7,我收到一个错误,提示“未定义 formState ”,尽管它已正确导入和使用。 这是我在我的应用程序中使用的一段代码,根据此处提供的文档正确显示:- https://react-hook-form.com/api/useform/formstate
const LoginForm = () => {
const { register, setError ,formState: { errors }, handleSubmit } = useForm();
const {sendSignInLinkToEmail} = useAuth();
const onSubmit = async data => {
// console.log(data);
try{
await sendSignInLinkToEmail(data.email);
}catch (error) {
setError("email", {
type: "manual",
message: error.message,
});
}
}
console.log(errors);
return(
<GridItem>
{ errors.email && (
<Alert status="error" variant="subtle" mt={6} mb={6}>
<AlertIcon />
{errors.email.message}
</Alert>
)}
{formState.isSubmitSuccessful && (
<Alert status="success" variant="subtle" mt={6} mb={6}>
<AlertIcon />
Check your email to complete login !!
</Alert>
)}
<form onSubmit={handleSubmit(onSubmit)}>
<FormControl>
<FormLabel htmlFor="email">Email</FormLabel>
<Input name="email" placeholder="Email" {...register('email')}></Input>
<Button mt={4} colorScheme="teal" isLoading={formState.isSubmitting} type="submit">Login</Button>
</FormControl>
</form>
</GridItem>
)
}
但我收到了这个错误
Line 50:14: 'formState' is not defined no-undef
Line 60:66: 'formState' is not defined no-undef
第 50 行是
{formState.isSubmitSuccessful && (
<Alert status="success" variant="subtle" mt={6} mb={6}>
<AlertIcon />
Check your email to complete login !!
</Alert>
)}
第 60 行是
<Button mt={4} colorScheme="teal" isLoading={formState.isSubmitting} type="submit">Login</Button>
来自 useForm 的错误也没有得到正确实现,setError 没有设置“错误” object 发生的错误,这里出了什么问题?
由于您将 formState 解构为错误{formState:{errors}}
只会返回错误,因此您可以使用 formState 的 rest 道具,而不会出现像{formState:{errors, ...formState}}
或类似的错误,或者只是简单地使用formState.errors
