I am not getting the choosen program option to select user,The props supposed to communicate from program.js to enrollmentform can anyone help me figuring out why the choosen program is not appearing
the code is --:
My App.js Code is ---:
import './App.css';
import EnrollmentForm from './EnrollmentForm';
function App() {
return (
<div className="App">
<EnrollmentForm >Just React</EnrollmentForm>
</div>
);
}
export default App;
My enrollmentform.js code is ---:
import { useState } from "react";
import "./App.css";
function EnrolmentForm(props) {
const [firstName, setFirstName] = useState("");
const [lastName, setLastName] = useState("");
const [welcomeMessage, setWelcomeMessage] = useState("");
const handleSubmit = (event) => {
setWelcomeMessage(`Welcome ${firstName} ${lastName}`);
event.preventDefault();
};
return (
<div>
<form className="enrolForm" onSubmit={handleSubmit}>
<h1>{props.chosenProgram} Student Details</h1>
<label>First name:</label>
<input
type="text"
name="fname"
onBlur={(event) => setFirstName(event.target.value)}
/>
<br />
<label>Last name:</label>
<input
type="text"
name="lname"
onBlur={(event) => setLastName(event.target.value)}
/>
<br />
<br />
<input type="submit" value="Submit" />
<br />
<label id="studentMsg" className="message">
{welcomeMessage}
</label>
</form>
</div>
);
}
export default EnrolmentForm;
my program.js code is ---:
import "./App.css";
import EnrolmentForm from "./EnrolmentForm";
import { useState } from "react";
function App() {
const [program, setProgram] = useState("UG");
const handleChange = (event) => {
setProgram(event.target.textContent);
};
return (
<div className="App">
<div className="programs">
<label>Choose Program:</label>
<select className="appDropDowns"
onChange={handleChange}
value={program} >
<option value="UG">Undergraduate</option>
<option value="PG">Postgraduate</option>
</select>
</div>
<EnrolmentForm chosenProgram={program} />
</div>
);
}
The desired output supposed to be--->
and the output which I am getting
There supposed to be a option of choosen program but it is not working and not apearing when I run the code
Your Code Should Look like This:
In App.js:
import './App.css';
import Program from './Program';
function App() {
return (
<div className="App">
<Program />
</div>
);
}
export default App;
In Enrollment.js code:
import { useState } from "react";
import "./App.css";
function EnrolmentForm(props) {
const [firstName, setFirstName] = useState("");
const [lastName, setLastName] = useState("");
const [welcomeMessage, setWelcomeMessage] = useState("");
const handleSubmit = (event) => {
setWelcomeMessage(`Welcome ${firstName} ${lastName}`);
event.preventDefault();
};
return (
<div>
<form className="enrolForm" onSubmit={handleSubmit}>
<h1>{props.chosenProgram} Student Details</h1>
<label>First name:</label>
<input
type="text"
name="fname"
onBlur={(event) => setFirstName(event.target.value)}
/>
<br />
<label>Last name:</label>
<input
type="text"
name="lname"
onBlur={(event) => setLastName(event.target.value)}
/>
<br />
<br />
<input type="submit" value="Submit" />
<br />
<label id="studentMsg" className="message">
{welcomeMessage}
</label>
</form>
</div>
);
}
export default EnrolmentForm;
And Program.js code:
import { useState } from "react";
import "./App.css";
import EnrolmentForm from "./EnrolmentForm";
function Program() {
const [program, setProgram] = useState("UG");
const handleChange = (event) => {
setProgram(event.target.textContent);
};
return (
<div className="App">
<div className="programs">
<label>Choose Program:</label>
<select
className="appDropDowns"
onChange={handleChange}
value={program}
>
<option value="UG">Undergraduate</option>
<option value="PG">Postgraduate</option>
</select>
</div>
<EnrolmentForm chosenProgram={program} />
</div>
);
}
export default Program;

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

</>
)
}
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">

I have the following code in my react app and I need to have empty input areas after submitting. Please assist me.

const Contact = () => {
const formRef = useRef();
const [done, setDone] = useState(false);

e.preventDefault();
emailjs.sendForm(
'service_py6v3mm',
'template_db5q8nx',
formRef.current,
'mJDC1if10C25Z-TZC'
)
.then((result) => {
console.log(result.text);
setDone(true);
}, (error) => {
console.log(error.text);
});
}
return (

export default Contact
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>
<>
)
}
Unable to get values in console!
What am I doing it incorrectly?
Attached below is the functional component of React
The Handler Functions
import React, { useState, useRef } from 'react';
const SimpleInput = (props) => {
const nameInputRef = useRef();
const [enteredName, setEnteredName] = useState('');
const nameInputChangeHandler = (event) => {
setEnteredName(event.target.value);
};
const formSubmissionHandler = (event) => {
event.preventDefault();
console.log(enteredName);
const enteredName = nameInputRef.current.value;
console.log(enteredName);
};
return (
<form>
<div className="form-control" onSubmit={formSubmissionHandler}>
<label htmlFor="name">Your Name</label>
<input
ref={nameInputRef}
type="text"
id="name"
onChange={nameInputChangeHandler}
/>
</div>
<div className="form-actions">
<button>Submit</button>
</div>
</form>
);
};
export default SimpleInput;
formSubmissionHandler should have on the form element rather than the div element.
return (
<form onSubmit={formSubmissionHandler}>
<div className="form-control">
<label htmlFor="name">Your Name</label>
<input
ref={nameInputRef}
type="text"
id="name"
onChange={nameInputChangeHandler}
/>
</div>
<div className="form-actions">
<button>Submit</button>
</div>
</form>
);
In this code, I want to upload the radio button value and store it in firebase database.I want use the simplest way to solve that. I see other code will use constructor but I do not know whether I can use simpler way to solve it. how can I do that ?
import React, { useState } from "react";
import ReactPlayer from "react-player";
import Array from "../Array";
import firebase from "firebase";
export default () => {
const [selected, setSelected] = useState("");
return (
<div>
<div className="video">
<ReactPlayer url={Array[0]} playing />
</div>
<label>Guess whether this video is fake or real ?</label> <br />
<label>
<input
type="radio"
name="answer"
value="real"
onChange={e => setSelected(e.target.value)}
/>
real
</label>
<label>
<input
type="radio"
name="answer"
value="fake"
onChange={e => setSelected(e.target.value)}
/>
fake
</label>
</div>
);
};
I would do it like this:
import React from "react";
....
export default () => {
const [state, setState] = React.useState({});
const handleInputChange = e => {
const { name, value } = e.target;
console.log(name, value);
setState(state => {
const newState = { ...state, [name]: value }
//post newState to firebase
return newState
});
};
return (
<div>
<div className="video">
<ReactPlayer url={Array[0]} playing />
</div>
<div>{JSON.stringify(state)}</div>
<label>Guess whether this video is fake or real ?</label> <br />
<label>
<input
type="radio"
name="answer1"
value="real"
onChange={handleInputChange}
/>
real
</label>
<label>
<input
type="radio"
name="answer2"
value="fake"
onChange={handleInputChange}
/>
fake
</label>
</div>
);
};
