React-我的表单正在提交空数据，因为已声明但从未使用过"e"和"data"? [英] React - My form is submitting empty data because 'e' and 'data' are declared but never used?
问题描述
我正在尝试使用 react-hook-form 来实现表单.我实际上无法正确连接数据和事件.docs指出，我正在使用react-hook-form库中的 handleSubmit 函数，并将我的自定义Axios帖子作为 onSubmit 参数:{handleSubmit(onSubmit)
I'm trying to implement a form using react-hook-form. I'm not able to actually connect the data and event working correctly. As the docs state, I'm using the handleSubmit function from the react-hook-form library, with my custom Axios post as the onSubmit parameter: onSubmit={handleSubmit(onSubmit)
根据我的Vscode，数据和事件未正确注册. const onSubmit =(data，e)=>{} .
According to my Vscode, the data and event are not registering correctly const onSubmit = (data, e) => {}.
提交表单后，Web控制台将记录一个空表单: {email:"，密码:''"}
When the form is submitted, the web console logs an empty form:
{email: "", password: ""}
我的代码在做什么错?为简洁起见，请注意，我删除了下面的密码文本字段.
What am I doing wrong with my code? Note for sake of brevity, I removed the password textfield below.
export default function SignIn()
{
const { register, control, errors: fieldsErrors, handleSubmit } = useForm()
const history = useHistory();
const initialFormData = Object.freeze({
email: '',
password: '',
});
const [formData, updateFormData] = useState(initialFormData);
const handleChange = (e) => {
updateFormData({
...formData,
});
};
const dispatch = useDispatch();
const onSubmit = (data, e) => {
console.log(formData);
axiosInstance
.post(`auth/token/`, {
grant_type: 'password',
username: formData.email,
password: formData.password,
})
.then((res) => {
console.log(res);
localStorage.setItem('access_token', res.data.access_token);
localStorage.setItem('refresh_token', res.data.refresh_token);
history.push('/');
window.location.reload();
dispatch(login({
name: formData.email,
password: formData.password,
loggedIn: true,
}))
})
};
const classes = useStyles();
return (
<Container component="main" maxWidth="xs">
<CssBaseline />
<div className={classes.paper}>
<Typography component="h1" variant="h5">
Sign in
</Typography>
<form className={classes.form} noValidate onSubmit={handleSubmit(onSubmit)}>
<FormControl fullWidth variant="outlined">
<Controller
name="email"
as={
<TextField
variant="outlined"
margin="normal"
inputRef={register}
required
fullWidth
id="email"
label="Email Address"
name="email"
autoComplete="email"
autoFocus
onChange={handleChange}
helperText={fieldsErrors.email ? fieldsErrors.email.message : null}
error={fieldsErrors.email}
/>
}
control={control}
defaultValue=""
rules={{
required: 'Required',
pattern: {
value: /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i,
message: 'invalid email address'
}
}}
/>
</FormControl>
如何正确链接所有内容并获取输入数据和事件以与表单中的 onSubmit = {handleSubmit(onSubmit)进行通信?
How can I link up everything correctly and get my input data and event to communicate with the onSubmit={handleSubmit(onSubmit) inside my form?
谢谢您的帮助！

推荐答案
为什么不使用 onSubmit 函数上的 data 参数?
Why not use the data parameter on the onSubmit function?
const onSubmit = (data, e) => {
console.log(data);
axiosInstance
.post(`auth/token/`, {
grant_type: 'password',
username: data.email,
password: data.password,
})
.then((res) => {
console.log(res);
localStorage.setItem('access_token', res.data.access_token);
localStorage.setItem('refresh_token', res.data.refresh_token);
history.push('/');
window.location.reload();
dispatch(login({
name: data.email,
password: data.password,
loggedIn: true,
}))
})
};
在 form
<Controller
as={
<TextField
variant="outlined"
margin="normal"
fullWidth
label="Email Address"
autoComplete="email"
autoFocus
error={Boolean(fieldsErrors.email)}
/>
}
name="email"
control={control}
rules={{
required: 'Required',
pattern: {
value: /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i,
message: 'invalid email address'
}
}}
defaultValue=""
/>
{fieldsErrors.email?.type && <p>{fieldsErrors.email?.message}</p>}
