Hello guys i have a react project made with react, node, express, and mysql. The thing is i want to get email from login and pass to home page. How do i do that, i dont want to use useParams() because the user can input their email in the link, i want to avoid that. Is there any way to do that and if you can, can you give code example.
Login
const Login = () => {
let navigate = useNavigate();
const [emailLog, setEmailLog] = useState("");
const [passwordLog, setPasswordLog] = useState("");
const [loginStatus, setLoginStatus] = useState("");
Axios.defaults.withCredentials = true;
const login = (e) => {
e.preventDefault()
Axios.post("http://localhost:3001/login" , {
email: emailLog,
password: passwordLog
}).then((response)=> {
console.log(response)
if(response.data.message) {
alert((response.data.message))
} else{
setLoginStatus(response.data[0].email)
alert("Redirecting")
navigate("/home")
}
})
}
useEffect(() => {
Axios.get('http://localhost:3001/login').then((response)=> {
if(response.data.loggedIn == true) {
setLoginStatus(response.data.email[0].email)
}
})
})
return (
<div>
<img className="wave" src={Wave} />
<img className="wave2" src={WaveV2} />
<div className="wrapper">
<div className="img">
{/* <img src={Background}/> */}
</div>
<div className="register-content">

<div className="input-div one">
<div className="i">

</div>
<div className="div">

onChange={(e)=> {
setEmailLog(e.target.value)
}}/>
</div>
</div>
<div className="input-div pass">
<div className="i">

</div>
<div className="div">
<input type="password" className="input" placeholder='Password' required
onChange={(e)=> {
setPasswordLog(e.target.value)
}}/>
</div>
</div>
Don't have an account ?
<button type='submit' className='btn' onClick={login} data={emailLog}>Login</button>
</div>
</div>
</div>
</div>
)
}
export default Login
App.js
function App() {
const [invoice, setInvoice] = useState("");
const [date, setDate] = useState ("");
const [currency, setCurrency] = useState ("IDR");
const [ myFile, setMyFile] = useState("");
const [test, setTest] = useState("anjay#anjay.com");
Axios.defaults.withCredentials = true;
return (
<div className="App">
<BasicExample />
<div className='formInput'>

<input className='inputForm' type="text" placeholder='Description' name='Description' />
<select className='selectBox' name='Currency' onChange={(e)=> {
setCurrency(e.target.value);
}}>
<option value="IDR">IDR</option>
<option value="USD">USD</option>
<option value="YEN">YEN</option>
</select>
<input className='inputForm' type="number" placeholder='Amount' name='Amount'/>
<input className='custom-file-upload' multiple type="file" name="DocumentFile" onChange={(e)=> {
setMyFile(e.target.value);
}} />
<button className='btnSubmit'>Submit</button>
</form>
</div>
</div>
);
}
export default App;
I think props drilling should solve it.
example
Login Component
function Login({email, setEmail}){
// you need to update state email here
}
Home or App.js
function App(){
const [email, setEmail] = useState("");
// here you should pass the props to login component,
// so you have the ability to set or asign the email state
<Login email={email} setEmail={setEmail} />
}
If you want to send data tp one page, you can use state with navigate.
navigate("/home", {state: { email: emailLog }})
you can get data from your home component like,
{props.location.state.email}

I am learning react and I have a component which as a 2 input fields and a button, at the moment, clicking on the button will display a message in console log, but when the button is clicked it displays a popup Leave site?, Changes that you made may not be saved.
this is my code in this component
import React, { useRef, useState, Component } from 'react'
import { useAuthState } from 'react-firebase-hooks/auth';
import { useCollectionData } from 'react-firebase-hooks/firestore';
import { signOut } from 'firebase/auth';
class InfoLgnTest extends Component {
render() {
this.state = {
user: null
}
return (
<div>
<div className="App">
<SignInWithEmailPassword />
</div>
</div>
)
}
}
function SignInWithEmailPassword() {
const emailRef = useRef()
const passwordRef = useRef()
const signIn = () => {
console.log("InfoLgnTest singin clicked")
}
return (
<>
<div className="form">
<form>
<div className="input-container">
<label>Username </label>
<input
name="email"
type="text"
ref={emailRef}
required
placeholder ="something#gmail.com"
/>
</div>
<div className="input-container">
<label>Password </label>
<input

/>
</div>
<div className="button-container">
<input type="submit" onClick={signIn}/>
</div>
</form>
</div>
</>
)
}
export default InfoLgnTest
This code has a form, by default form send data as a request on the same page, for resolve this:
Add onSubmit to form,
call preventDefault method from event
call the function signIn
Change <input type="submit" ... /> to <button type="submit">Send</button>
function SignInWithEmailPassword() {
const emailRef = useRef()
const passwordRef = useRef()
const signIn = () => {
console.log("InfoLgnTest singin clicked")
}
// new function to handle submit
const submitForm = (event) => {
event.preventDefault();
signIn();
}
return (
<>
<div className="form">
{/* Add onSubmit */}
<form onSubmit={submitForm}>
<div className="input-container">
<label>Username </label>
<input
name="email"
type="text"
ref={emailRef}
required
placeholder ="something#gmail.com"

</div>
<div className="input-container">

You can bind every input value to a state and empty them when you submit it. Here I add an example for the username. You can multiply it and use it.
const [username, setUsername] = useState('Name');
const submitFunctionWhichDeletes = () => {
console.log(username);
setUsername('');
}
<input ... value={username} onChange={e => setUsername(e.target.value)} ... />
const compForm = ()=>{
const [formData,addFormData] = useState({
username:"",
subject:"",
email:"",
message:""
})
cosnt formSubmit =()=>{
// make api call
addFormData({
username:"",
subject:"",
email:"",
message:""
})
}
const formData = (e,filed)=>{
const temp = {...formData}
if (filed === "username"){
temp.username = e.target.value
}
else if(filed === "subject"){
temp.subject = e.target.value
}
else if(filed === "email"){
temp.email = e.target.value
}
else if(filed === "message"){
temp.message = e.target.value
}
addFormData(temp)
}
return(
<>
<input type='text' placeholder='Name' name='username'
value={formData.username} onChange={(e)=>formData(e,username)}/>
<input type='text' placeholder='Subject' name='user_subject'
value={formData.subject} onChange={(e)=>formData(e,subject)}/>
<input type='text' placeholder='Your email here... ' name='user_email'
value={formData.email} onChange={(e)=>formData(e,email)}/>
<textarea rows={5} placeholder='message' name='message'
value={formData.message} onChange={(e)=>formData(e,message)}/>
<button onClick = {(e)=>formSubmit()}>Submit</button>
<>
)
}
So I've created inputs in two functions and on Onchange it gets the value that is being input into them. But anytime I type into the inputs I can only type a letter at a time before it is unfocused and I believe this is because the component keeps on rendering.
I've also realized that whenever I remove the Onchange and value props then everything goes back to normal and I'm able to type everything easily. How would I fix this?

Don't put your component definition inside the other component. If you do it, you create a new component at every render.
You need to work around to move Emailform, Passform to outside of Auth.
Checkout this sandbox to experiment
function Auth() {
// 🚫 the bad place to define components
const Emailform = () => {
...
}
// 🚫 the bad place to define components
const Passform = () => {
...
}
}
I am a beginner in react. I was working on the react function component with forms using hooks. Can anyone please tell how can I apply validation on email text when it is invalid or empty, and disable the continue button if the form is not valid.
import React, { useState } from "react";
const ForgotPassowrd = () => {
const [emailId, setemailId] = useState("");
const forgotPasswordClick = (event) => {};
return (

<div className="form-body">
<form action="#">
<div>
<div className="form-group">
<label htmlFor="password">Email-Id</label>
<div className="input-group">
<input type="text" className="form-control" value={emailId} onChange={(event)=>
setemailId(event.target.value)}/>
</div>
</div>
<button type="button" onClick={forgotPasswordClick} className="btn btn-lg

**Try it.This may be helpfull for you! If you can any queries comment below.**
