I'm working in a personal project and I was trying to implement a string interpolation, but for some reason it isn't working and it is throwing an error.
I'm using visual studio code and the errors it's throwing are the following:
Property assignement expected
';' expected (2 times)
Declaration or statement expected
this is the line where I put the specific interpolation:
newsection = {`${newsectionnmb}`:"placeholder"}
this is my complete code:
import React, { Component } from "react";
import { NavLink, match } from "react-router-dom";
import { withRouter } from "react-router-dom";
import axios from "axios";
class AddContent extends Component{
constructor(props) {
super(props)
this.state = {
name: "",
content: "",
courseName:"",
actualContent: [],
section:"NEW",
video: ""
}
this.handleChange = this.handleChange.bind(this);
this.handleSubmit = this.handleSubmit.bind(this);
}
componentDidMount() {
axios.get(`http://localhost:5000/course/id/${Number(this.props.match.params.id)}`)
.then( (response)=> {
this.setState({
courseName: response.data.name,
actualContent: response.data.content
});
if(this.props._id != response.data.adminId) {
this.props.history.push("/");
}
})
.catch(function (error) {
console.log(error);
alert("we couldn't fetch the course data, try again later by reloading the page")
})
}
handleChange(event) {
const target = event.target;
const value = target.value;
const name = target.name;
this.setState({
[name]: value
});
}
handleSubmit= (event)=> {
if (this.state.name !== "" ) {
if (this.state.section === "NEW") {
newsectionnmb = this.state.actualContent.length +1;
newsection = {`${newsectionnmb}`:"placeholder"}
}
event.preventDefault();
axios({
method: 'put',
url: `http://localhost:5000/course/add-content/${Number(this.props.match.params.id)}`,
data: {
content: this.state.content
}
})
}
}
render() {
let sectionlist = this.state.actualContent.length > 0
&& this.state.actualContent.map((item, i) => {
return (
<option key={i} value={item.name}>{item.name}</option>
)
}, this);
return (

export default withRouter(AddContent);
If you want to make newsection an object, it should be done like this
newsection = {newsectionnmb:"placeholder"}
If you are trying to make it a string, this should work for you
newsection = `${newsectionnmb}:"placeholder"`

Hello peepz of the web,
I've ran into mysterious corridor, which's too dark for me to see what the hell I'm going.. would love someone's flashlight to shine the way.
I have created a simple, poor to do list program.
It's combined from Task.js, TaskList.js and NewTaskForm.js.
From the NewTaskForm.js I'm retrieving input, passing it to the parent, TaskList.js.
On TaskList.js I'm adding a key to the task object:
handleSubmit(task2add){
let keyid = v4();
console.log(keyid);
let task2addWithID = { ...task2add, id: {keyid}, key: {keyid}};
this.setState(st => ({
todoArr: [...st.todoArr, task2addWithID],
}));
}
Now, in TaskList.js, in my render function, I'm creating Tasks:
render() {
let tasklist = this.state.todoArr.map(task => (
<div>
<Task
taskTitle={task.title}
taskText={task.text}
key={task.key}
id={task.id}
handleRemove={this.handleRemove}
handleEdit={this.handleEdit}
/>
</div>
));
return (
<div>
<h1>TaskList</h1>
<div className='TaskList'>
<div className='TaskList-title'>
{tasklist}
</div>
<NewTaskForm key={1} handleSubmit={this.handleSubmit}/>
</div>
</div>
)
}
now, what is so confusing for me is why when I'm doing in my Tasks.js class:
console.log(this.props.id);
it prints me an object?
I would expect it to.. print me a value? where along the way did it wrap it with an object?
Full (shitty) code below.
Plus #1, if anyone knows to tell me why still I get the warning the key, even though, at least for my poor experience, I have given it a key?
Plus #2, why even when I send the handleRemove function in TaskList.js the proper id, it doesn't erase the bloody task? :-(
Regards!

}
}
Because you have created an object here:
{ ...task2add, id: {keyid}, key: {keyid}};
{keyid}
is the same as
{keyid: keyid}
You wanted to do this:
{ ...task2add, id: keyid, key: keyid};
I'm assuming its because you're setting the state like this:
let task2addWithID = { ...task2add, id: {keyid}, key: {keyid}};
The id attribute is assigned an object. If you did:
let task2addWithID = { ...task2add, id: keyid, key: {keyid}};
console logging id should print out a string

how can i avoid above console error occured?
I think your problem is in your effect, particularly in the way you use setExercise, when you do:
setExercise({
users: response.data.map(user => user.username),
username: response.data[0].username
})
It doesn't "merge" (assign) the new data with previous state, what it does - is just sets the state, meaning your state object after this will be:
{ users:[], username:''}
So you actually lose description and other fields - hence the warning.
What you should do, is this:
setExercise((prevState) => ({
...prevState,
users: response.data.map(user => user.username),
username: response.data[0].username
}))
I just started working with React and JSON and require some help. There is a textarea field in which a user enters some data. How to read row-wise the entered text as an array into a JSON variable of the request? Any assistance would be greatly appreciated.
The result I want is
{
id: 3,
name: 'Monika',
birthDay: '1999/01/01',
countryDTO: 'USA',
films: [
'Leon:The Professional',
'Star wars',
'Django Unchained',
],
} ```
My code:
import React from 'react';
import { Form, FormGroup, Label } from 'reactstrap';
import '../app.css';
export class EditActor extends React.Component {
state = {
id: '',
name: '',
birthDay: '',
countryDTO: '',
films: [],
}
componentDidMount() {
if (this.props.actor) {
const { name, birthDay, countryDTO, films } = this.props.actor
this.setState({ name, birthDay, countryDTO, films });
}
}
submitNew = e => {
alert("Actor added"),
e.preventDefault();
fetch('api/Actors', {
method: 'post',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({

.then(() => {
this.props.toggle();
})
.catch(err => console.log(err));
this.setState({
id: '',
name: '',
birthDay: '',

films: ''
});
}
onChange = e => {
this.setState({ [e.target.name]: e.target.value })
}
render() {
return <div>

If you change the below code it will work automatically.
State declaration
this.state = {
name: 'React',
films:["Palash","Kanti"]
};
Change in onechange function
onChange = e => {
console.log("values: ", e.target.value)
this.setState({ [e.target.name]: e.target.value.split(",") })
}
change in textarea
<textarea name="films" value={this.state.films.map(r=>r).join(",")} onChange={this.onChange} />
Code is here:
https://stackblitz.com/edit/react-3hrkme
You have to close textarea tag and the following code is :
<textarea name="films" value={this.state.films} onChange={this.onChange} >{this.state.films}</textarea>
My understanding of your problem is that you would like to have each line in the text area dynamically added as an entry in the films array. This can be achieved as follows:
import React, { Component } from "react";
export default class textAreaRowsInState extends Component {
constructor(props) {
super(props);
this.state = {
currentTextareaValue: "",
films: []
};
}
handleChange = e => {
const { films } = this.state;
const text = e.target.value;
if (e.key === "Enter") {
// Get last line of textarea and push into films array
const lastEl = text.split("\n").slice(-1)[0];
films.push(lastEl);
this.setState({ films });
} else {
this.setState({ currentTextareaValue: text });
}
};
render() {
const { currentTextareaValue } = this.state;
return (
<textarea
defaultValue={currentTextareaValue}
onKeyPress={this.handleChange}
/>
);
}
}
Keep in mind that this method is not perfect. For example, it will fail if you add a new line anywhere other than at the end of the textarea. You can view this solution in action here:
https://codesandbox.io/s/infallible-cdn-135du?fontsize=14&hidenavigation=1&theme=dark
change textarea() tag
to
<textarea name="films" value={this.state.films} onChange={this.onChange} >{this.state.films}</textarea>
You can use split() :
films: {this.state.films.split(",")}
So I was following a simple react/firebase chat room on youtube: https://www.youtube.com/watch?v=or3Gp29o6fE as a reference to what I'm doing with my project. I am making a bug/issue tracker, so that a user can enter a station #, bug/issue, then a description of it. I keep getting an error:
Error: Reference.set failed: First argument contains undefined in property 'bugs.0.station'
And I'm not sure how it's undefined if it's just an id number. My end goal at this point in time is to be able to add and remove a bug/issue by id.
import React, { Component } from 'react';
import { Button } from "react-bootstrap";
import withAuthorization from './withAuthorization';
import * as firebase from 'firebase';
class HomePage extends Component {
constructor(props,context) {
super(props,context);
this.stationBug = this.stationBug.bind(this)
this.issueBug = this.issueBug.bind(this)
this.descBug = this.descBug.bind(this)
this.submitBug = this.submitBug.bind(this)
this.state = {
station: '',
bug: '',
desc: '',
bugs: []
}
}
componentDidMount() {
firebase.database().ref('bugs/').on ('value', (snapshot) => {
const currentBugs = snapshot.val()
if (currentBugs != null) {
this.setState({
bugs: currentBugs
})
}
})
}
stationBug(event) {
this.setState({
station: event.target.value
});
}
issueBug(event) {
this.setState({
bug: event.target.value
});
}
descBug(event) {
this.setState({
desc: event.target.value
});
}
submitBug(event) {
const nextBug = {
id: this.state.bugs.length,
station: this.state.title,
bug: this.state.bug,
desc: this.state.desc
}
firebase.database().ref('bugs/'+nextBug.id).set(nextBug)
}
render() {
return (
<div className="App">
{
this.state.bugs.map((bug, i) => {
return (
<li key={bug.id}>{bug.station}</li>
)
})
}
<input onChange={this.stationBug} type="text" placeholder="Station #" />
<br />
<textarea onChange={this.issueBug} type="text" placeholder="Bug/Issue" />
<br />
<textarea onChange={this.descBug} type="text" placeholder="Bug Description" />
<br />
<Button onClick={this.submitBug} type="button"> Enter Bug </Button>
</div>
);
}
}
export default withAuthorization()(HomePage);
Just looks like a typo. You're referencing this.state.title instead of this.state.station in your submitBug method.
class HomePage extends Component {
constructor(props) {
super(props);
this.state = {
station: '',
bug: '',
desc: '',
bugs: []
}
}
componentDidMount() {
firebase.database().ref('bugs/').on ('value', (snapshot) => {
const currentBugs = snapshot.val()
if (currentBugs != null) {
this.setState({
bugs: currentBugs
})
}
})
}
stationBug=(event)=>{
this.setState({
station: event.target.value
});
}
issueBug=(event)=>{
this.setState({
bug: event.target.value
});
}
descBug=(event)=>{
this.setState({
desc: event.target.value
});
}
submitBug=(event)=>{
const nextBug = {
id: this.state.bugs.length,
station: this.state.title,
bug: this.state.bug,
desc: this.state.desc
}
firebase.database().ref('bugs/'+nextBug.id).set(nextBug)
}
render() {
return (
<div className="App">
{this.state.bugs.map(bug => <li key={bug.id}>{bug.station}</li>)}
<input onChange={this.stationBug} type="text" placeholder="Station #" />
<br />
<textarea onChange={this.issueBug} type="text" placeholder="Bug/Issue" />
<br />
<textarea onChange={this.descBug} type="text" placeholder="Bug Description" />
<br />
<Button onClick={this.submitBug} type="button"> Enter Bug </Button>
</div>
);
}
}
export default withAuthorization()(HomePage);
The error is quite explicit:
Reference.set failed: First argument contains undefined in property 'bugs.0.station'
Since there's only one call to Reference.set() in your code, the problem must be here:
submitBug(event) {
const nextBug = {
id: this.state.bugs.length,
station: this.state.title,
bug: this.state.bug,
desc: this.state.desc
}
firebase.database().ref('bugs/'+nextBug.id).set(nextBug)
}
So it seems that this.state.title is undefined. Most likely you wanted to use station: this.state.station.
I am following a tutorial and cannot get the following code to run.
When I run the following code I get the error Can't add property attachToForm, object is not extensible. Are you no longer to allowed to change child props in this way (ie. with child.props.key = value)? If not can you see a better way of adding a function to nested children only if the element is an input?
React.Children.forEach(children, function (child) {
