I'm new to both react and material ui and I'm having an issue where my text fields work fine but if the user has saved data to autofill the field it breaks the styling on it. I have included the code from the component below. I apologize if this is a dumb question but I googled it and didn't find anything helpful.
import React, {useState} from 'react';
import { Grid, Button, TextField, CardContent } from '#mui/material';
import Box from '#mui/material/Box';
import Auth from '../utils/auth';
import { useMutation } from '#apollo/client';
import { LOGIN_USER } from '../utils/mutations';
import FormControl from '#mui/material/FormControl';
const LoginForm = () => {
const [userFormData, setUserFormData] = useState({ email: '', password: '' });
const [validated] = useState(false);
const [showAlert, setShowAlert] = useState(false);
const [login] =useMutation(LOGIN_USER);
const handleInputChange = (event) => {
const { name, value } = event.target;
setUserFormData({ ...userFormData, [name]: value });
};
const handleFormSubmit = async (event) => {
event.preventDefault();
const form = event.currentTarget;
if (form.checkValidity() === false) {
event.preventDefault();
event.stopPropagation();
}
try {
const data= await login({
variables: {...userFormData}
});
console.log(data);
Auth.login(data.data.login.token);
} catch (err) {
console.error(err);
setShowAlert(true);
}
setUserFormData({
username: '',
email: '',
password: '',
});
};
return (
<Box style={{ maxWidth: 650, margin: "0 auto", padding: "20px 5px" }}>

I am using react-hook-form V7 with Material UI to create a simple form however, there is a weird behavior when setting the mode in useForm({mode: ".."})
Here is my code snippet:
import { yupResolver } from "#hookform/resolvers/yup";
import { Button, Grid, Link, TextField, Typography } from "#material-ui/core";
import { makeStyles } from "#material-ui/core/styles";
import Alert from "#material-ui/lab/Alert";
import { Controller, useForm } from "react-hook-form";
import { _MESSAGES } from "src/constants/messages";
import * as yup from "yup";
import AuthContainer from "./AuthContainer";
// ##################### Helpers ######################
/**
* #param {object} error
* #param {string} msg
*/
const renderError = (error, msg) =>
error ? <Alert severity="error">{msg}</Alert> : "";
// ############## Schema & Default Values ##############
const schema = yup.object().shape({
email: yup.string().required(),
password: yup.string().required(),
});
const defaultValues = {
email: "",
password: "",
};
// ###################### Styles ######################
const useStyles = makeStyles((theme) => ({
form: {
width: "100%", // Fix IE 11 issue.
marginTop: theme.spacing(1),
},
submit: {
margin: theme.spacing(3, 0, 2),
},
}));
// ################# Main Component ###################
const SignInPage = () => {
const classes = useStyles();
const {
handleSubmit,
formState: { errors },
reset,
control,
} = useForm({
mode: "all",
resolver: yupResolver(schema),
defaultValues,
});
const onSubmit = (data) => {
console.log(data);
// Reset form fields
reset();
};
console.log(errors);
const Form = () => (
<>
<Typography component="h1" variant="h5">

</Typography>
<form className={classes.form} onSubmit={handleSubmit(onSubmit)}>
<Controller
control={control}
name="email"
render={({ field }) => (
<TextField
variant="outlined"
margin="normal"
fullWidth
autoComplete="email"
label="Email Address"
{...field}
error={errors.email?.message ? true : false}
/>
)}
/>
{renderError(errors.email?.message, _MESSAGES.required)}
<Controller

render={({ field }) => (
<TextField

</Grid>
<Grid item>
<Link href="#" variant="body2" color="secondary">
{"Don't have an account? Sign Up"}
</Link>
</Grid>
</Grid>
</form>
</>
);
return <AuthContainer Form={<Form />} />;
};
export default SignInPage;
What might have gone wrong?
Here is a Gif of what happened:
selected the input field
started typing
after one char it leaves the input field so, I need to select it to type again.
Move your Form component to its own Component, otherwise, you are mount and unmount your Form Component each re-render.
const App = () => {
const Form = () => {} // mount and unmount with each re-render
return <div><Form /></div>
}
to
const Form = () => {}
const App = () => {
return <div><Form /></div>
}
You have to pass down the ref. For MUI TextField should do the following:
<Controller
control={methods.control}
name="fieldName"
render={({ field: { ref, ...field } }) => (
<TextField {...field} inputRef={ref} /> // ⬅️ The ref
)}
/>
A working demo: https://codesandbox.io/s/broken-microservice-xpuru
Does it work now ?
How can i make the relevant asp.net controller for this?
I have added the 'load user' functions to App.js also. What I want is to load the user every time the page is refreshed. The login function is working properly but when the page is refreshed the authentication will be null again.
"export const loadUser = () => async (dispatch) => {
if (localStorage.token) {
setAuthToken(localStorage.token);
}
try {
const res = await axios.get('https://localhost:5001/api/auth/user');
dispatch({
type: USER_LOADED,
payload: res.data,
});
} catch (err) {
dispatch({
type: AUTH_ERROR,
});
}
};"

I think in initial state of redux you need to check whether or not localStorage.token is not null/expired and set it back to user. So that whenever you refresh the page user da still can load
I was able to resolve above issue by using jwt_decode
if (localStorage.token) {
setAuthToken(localStorage.token);
var decoded = jwt_decode(localStorage.token);
}
try {
const res = await axios.get(`https://localhost:5001/api/auth/user/${decoded.Id}`);
dispatch({
type: USER_LOADED,
payload: res.data,
});
} catch (err) {
dispatch({
type: AUTH_ERROR,
});
}
};
I am following this example for a basic login screen. Very new to React but I found it to be pretty simple so far.
Unfortunately, as you can see in the screenshot below, the TextAreas look really bad! It seems like the inner padding is messed up.
I'm not sure what I'm doing wrong.
The fields should look like this:
Here is the code:

showPassword: boolean;
}
const useStyles = makeStyles((theme) => ({

margin: theme.spacing(8, 4),
display: 'flex',
flexDirection: 'column',
alignItems: 'center',
},

backgroundImage: '',

backgroundPosition: 'center',
},
form: {
marginTop: theme.spacing(1),
width: '100%',
},

margin: theme.spacing(1),
},
submit: {
margin: theme.spacing(3, 0, 2),
},
}));
export const ReactLoginComponent: FunctionComponent<ComponentProps> = (props) => {
const classes = useStyles();
const [values, setValues] = useState({
email: '',

});
const handleChange = (prop) => (event: React.ChangeEvent<HTMLInputElement>) => {
setValues({ ...values, [prop]: event.target.value });
};
const handleClickShowPassword = () => {
setValues({ ...values, showPassword: !values.showPassword });
};
const handleMouseDownPassword = (event: React.MouseEvent<HTMLButtonElement>) => {
event.preventDefault();
};
const login = (event: React.MouseEvent<HTMLButtonElement>) => {
event.preventDefault();
alert(`Welcome ${values.name}`);
};

Edit:
I should've mentioned that I'm using React inside an Angular application that is using Angular Material and has global overrides for certain components. This is probably where the issue is coming from. How can I negate those global changes from this React component specifically? Or could I override them in this component?
I'm kinda new to react and was wondering how to internally redirect your pages in reactjs. I have two pages called register and register2. In register page, I just check if the email exists in the database or not and if it doesn't exist then it redirects to register2 page for creating the full account with username and password. However, in the address bar, it kinda looks ugly to show something like register2. So I was wondering if there is any way through which I can internally redirect without changing the address in the address bar to register2 such that it stays as register throughout the whole account creation process.
I created a codesandbox to show the issue

export default withRouter(Reg2);
you could make a parent component for register and register2 and store your logic there in which component to display
function MyComponent() {
const [email, setEmail] = useState(null)
useEffect(() => {
(async () => {
const response = await yourApiCall()
setEmail(response)
})()
}, [])
return email ? <Register /> : <Register2 />
}
Initially show the register component or code of that sort.
Call an api, if the email exists, store flag value in that and do conditional rendering for another component or code of register2.
Initially, this.state.isEmailExist : false,
After api call change flag value accordingly. If true then render Register2.
const contents = if (!this.state.isEmailExist) {
return (
<Register />
);
} else {
return (
<Register2 />
)
}
return(
<div>{contents}</div>
)

Make sure to setup the validation.
I have created a form with material ui, and I would like to clear it. I have searched for answers/solutions across Stackoverflow but all of them are not working for me.
I have tried by using setstate but it not result to clear the form.
I want to know how to do this using onclick event of the button.
import React, { Component } from "react";
import {
Grid,
TextField,
AppBar,
Typography,
Toolbar,
Button
} from "#material-ui/core";
export class MyInput extends Component {
constructor(props) {
super(props);
this.state = {
first_name: "",
last_name: ""
};
}
handle_input = (name, value) => {
let cur_state = this.state;
cur_state[name] = value;
this.setState(cur_state);
};
render() {
return (
<Grid container justify="center">
<Grid item md={4}>
<TextField
defaultValue={this.state.first_name}
variant="outlined"
label="First Name"
onKeyUp={(e) => {
this.handle_input("first_name", e.target.value);
}}
/>
</Grid>
<Grid item md={4}>
<TextField
defaultValue={this.state.last_name}
variant="outlined"
label="Last Name"
onKeyUp={(e) => {
this.handle_input("last_name", e
.target.value);
}}
/>
</Grid>
<Grid item md={4}>
<div
style={{
width: "100%",
padding: "10px",
display: "flex",
justifyContent: "space-between"
}}
>
<Button color="primary" variant="contained">
save
</Button>
<Button
color="secondary"
variant="contained"
onClick={() => {
this.setState({
first_name: "",
last_name: ""
});
}}
>
cancel
</Button>
</div>
</Grid>
</Grid>
);
}
}
export default MyInput;
Inside the TextField set a value,
<TextField
value={this.state.first_name}
defaultValue={this.state.first_name}
variant="outlined"
label="First Name"
onKeyUp={(e) => {
this.handle_input("first_name", e.target.value);
}}
/>
Then when you want to clear it, just use setState
this.setState({ first_name: '' })
Edit:
In fact, you can delete defaultValue as the default is an empty string anyways, which is what you're using.
<TextField
value={this.state.first_name}
variant="outlined"
label="First Name"
onKeyUp={(e) => {
this.handle_input("first_name", e.target.value);
}}
/>
It may be worth reading the react docs, basically you're wanting to override the form's internal state, which you do by using the value prop
I dont know if this will help as I am pretty new to react myself but you could try making a functional component instead of a class to help reduce the amount of code you need, i would do something like this
import React, {useState} from "react";
export default function MyInput(props) {
const [myState, setMyState] = useState(props);
function clearState() {
setMyState.first_name("")
setMyState.last_name("")
}
return (
//Your grid code here
)
//set your button on click to this
onClick = {() => {clearState()}}
Look into writing components like this its quite nice. Again this will need tweaking but may be a point in the right direction.
