当我尝试使用react-hook-form
实现Axios post时,我收到以下错误:
Unhandled Rejection (TypeError): e.preventDefault is not a function
当我将onSubmit={handleSubmit(handleSubmitAxios)}
添加到我的<form>
时,问题开始出现。基本上,我希望我的表单由react-hook-form
控制,使用我的自定义handleSubmitAxios
post调用与我的后端通信。
这是我的登录组件,目前正在测试react-hook-form的功能,但是e.preventDefault
消息让我很困惑。
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 handleSubmitAxios = (e) => {
e.preventDefault();
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(handleSubmitAxios)}
>
<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>
<Button
type="submit"
fullWidth
variant="contained"
color="primary"
className={classes.submit}
onClick={handleSubmit}
>
Sign In
</Button>
</form>
</div>
</Container>
);
}
感谢您对我如何解决原始错误的任何帮助或指导!

根据文档,第一个参数是
data or errors
对象,第二个参数是form event
。((数据:对象,e?:事件)=〉无效,(错误:对象,e?:事件)=〉无效)=〉函数
在你的例子中,
e
是数据,这就是为什么你得到的e.preventDefault
不是函数错误。这样试试
但是,
react-hook-form
已经阻止了默认的表单事件,不知道为什么你要再做一次。检查一次这个屏幕截图和demo
