I am using the jQuery serializeArray method to create an array of objects from a form, but the form already outputs an object. How would I rewrite this to vanilla JavaScript?
e.serializeArray().map(x=>{

e.find('input[name="'+x.name+'"]').val(cookie_val).change();
}

I have built a calculator using JS/React and I can’t seem to implement a function.
Basically I want that if 2 or more operators are entered consecutively, the operation performed should be the last operator entered (excluding the negative (-) sign).
So 2*-9=-18, but 12*-/3=4.
Also when I type 5*-, without even entering a second operand, it becomes 5*5.
My Code:
const { useState } = React;
function Calculator() {
const [displayValue, setDisplayValue] = useState('0');
const [firstOperand, setFirstOperand] = useState(null);
const [operator, setOperator] = useState(null);
const [waitingForSecondOperand, setWaitingForSecondOperand] = useState(false);
const inputDigit = (digit) => {
if (waitingForSecondOperand) {
setDisplayValue(String(digit));
setWaitingForSecondOperand(false);
} else {
setDisplayValue(displayValue === '0' ? String(digit) : displayValue + digit);
}
};
const inputDecimal = () => {
if (!displayValue.includes('.')) {
setDisplayValue(displayValue + '.');
}
};
const performOperation = (nextOperator) => {
const inputValue = parseFloat(displayValue);
if (firstOperand === null) {
setFirstOperand(inputValue);
} else if (operator) {
const result = calculate(firstOperand, inputValue, operator);
setDisplayValue(String(result));
setFirstOperand(result);
}
setWaitingForSecondOperand(true);
setOperator(nextOperator);
};
const calculate = (firstOperand, secondOperand, operator) => {
switch (operator) {
case '+':
return firstOperand + secondOperand;
case '-':
return firstOperand - secondOperand;
case '*':
return firstOperand * secondOperand;
case '/':
return firstOperand / secondOperand;
default:
return secondOperand;
}
};
const resetCalculator = () => {
setDisplayValue('0');
setFirstOperand(null);
setOperator(null);
setWaitingForSecondOperand(false);
};
return (
<div className="calculator">
<div id="display" className="display">{displayValue}</div>
<button id="clear" className="button" onClick={resetCalculator}>AC</button>
<button id="divide" className="button operator" onClick={() => performOperation('/')}>/</button>
<button id="multiply" className="button operator" onClick={() => performOperation('*')}>*</button>
<button id="subtract" className="button operator" onClick={() => performOperation('-')}>-</button>
<button id="seven" className="button" onClick={() => inputDigit(7)}>7</button>
<button id="eight" className="button" onClick={() => inputDigit(8)}>8</button>
<button id="nine" className="button" onClick={() => inputDigit(9)}>9</button>
<button id="add" className="button operator" onClick={() => performOperation('+')}>+</button>
<button id="four" className="button" onClick={() => inputDigit(4)}>4</button>
<button id="five" className="button" onClick={() => inputDigit(5)}>5</button>
<button id="six" className="button" onClick={() => inputDigit(6)}>6</button>
<button id="decimal" className="button" onClick={inputDecimal}>.</button>
<button id="one" className="button" onClick={() => inputDigit(1)}>1</button>
<button id="two" className="button" onClick={() => inputDigit(2)}>2</button>
<button id="three" className="button" onClick={() => inputDigit(3)}>3</button>
<button id="equals" className="button equals" onClick={() => performOperation('=')}>=</button>
<button id="zero" className="button" onClick={() => inputDigit(0)}>0</button>
</div>
);
}
ReactDOM.render(<Calculator />, document.getElementById('root'));
I have tried everything that came to mind but nothing seems to work, or even if it works it will break the whole calculator.
For context, I am a software engineer in an MNC with about two years of experience.
I have worked in manual and very little automated testing, primarily. I have little experience in SQL and databases and currently working as data extractor, meaning, some data is required and I code SQL queries for it.
I want to advance my career in development but don’t know where to start. With AI improving by the minute, I want to get ahead of the curve and build a more lucrative career in software development while also ensuring job security and industry relevance.
I do have an undergraduate degree in computer science but no development experience so far.
I watched this video, https://www.youtube.com/watch?v=9s29LKfEFjQ&t=478s , essentially advising to build javascript websites as a start. On the contrary, I have heard that efforts in web development will go in vain.
People also advise on learning AI and ML. But should I just start with it, without getting any solid foundation of software engineering/full stack development?
Long story short, I have received a lot of advices and am overwhelmed. Can anyone with good experience please suggest?
Thanks in advance!
im trying to click on a canvas programmaticaly but without result
given this canvas of a mine sweeper
https://minesweeperonline.com/
with this function i find the coordinates to be clicked
function handleMouseClick(event) {
var x = event.clientX;
var y = event.clientY;
console.log("Mouse clicked at coordinates - X: " + x + ", Y: " + y);
}
document.addEventListener('click', handleMouseClick);
then i try to simulate the click
function simulateClick(x, y) {
var event = new MouseEvent('click', {
'view': window,
'bubbles': true,
'cancelable': true,
'clientX': x,
'clientY': y
});
var element = document.elementFromPoint(x, y);
if (element) {
element.dispatchEvent(event);
} else {
console.error('No element found at the specified coordinates.');
}
}
but then when i simulateClick(456, 221)
i see the event dispatching (because it prints again Mouse clicked at coordinates - X: 456, Y: 221)
but nothing happens on the canvas.
any help?

I will show the structure in a screenshot below:
Im very new to JavaScript so i don’t know if this is even possible. I have a searchbar with an autocomplete function and i also have a few buttons that can change my websites language:
//searchbar//
let availableKeywords = [
'example1',
'exapmle2',
'example3'
];
const resultsBox = document.querySelector(".result-box");
const inputBox = document.getElementById("query");
inputBox.onkeyup = function(){
let result = [];
let input = inputBox.value;
if(input.length){
result = availableKeywords.filter((keyword)=>{
return keyword.toLowerCase().includes(input.toLowerCase());
});
console.log(result);
}
display(result);
if(!result.length){
resultsBox.innerHTML = '';
}
}
function display(result){
const content = result.map((list)=>{
return "<li onclick=selectInput(this)>" + list + "</li>";
});
resultsBox.innerHTML = "<ul>" + content.join('') + "</ul>";
}
function selectInput(list){
inputBox.value = list.innerHTML;
resultsBox.innerHTML = '';
}
//buttons//
const langEl = document.querySelector(".langWrap");
link.forEach((el) => {
el.addEventListener("click", () => {
langEl.querySelector(".active").classList.remove("active");
el.classList.add("active");
});
I was wondering if it was possible that the content of availableKeywords could change language depending on wich language button is active?
I have app.ts file:
import express, { Express } from "express";
import cors from "cors";
import cookieParser from "cookie-parser";
//
import userRouter from "./routes/userRoutes";
import cardsRouter from "./routes/cardsRoutes";
import contactsRouter from "./routes/contactsRoutes";
import transferRouter from "./routes/transferRoutes";
import authRouter from "./routes/authRoutes";
//
const app: Express = express();
app.use(express.json());
app.use(cookieParser());
app.use(
cors({
credentials: true,
origin: "http://localhost:4200",
})
);
app.get("/", (req, res) => {
res
.status(202)
.cookie("Name", "testCookie", {
sameSite: "strict",
path: "/",
expires: new Date(new Date().getTime() + 100 * 1000),
httpOnly: true,
secure: false,
})
.send("success!");
});
app.use("/api/v1", [
userRouter,
cardsRouter,
contactsRouter,
transferRouter,
authRouter,
]);
export default app;
and service:
import { Injectable } from '@angular/core';
import { CookieService } from 'ngx-cookie-service';
import axios from 'axios';
axios.defaults.withCredentials = true;
@Injectable({
providedIn: 'root',
})
export class AuthService {
constructor(private cookieService: CookieService) {}
url = 'http://localhost:8000/api/v1/login';
token: string = '';
async login(formObject: any) {
try {
await axios
.get(`${this.url}`, { withCredentials: true })
.then((res) => console.log(res));
console.log('http cookie set!');
} catch (error) {
console.error(error);
}
}
}
login route leads to this controller:
export const checkCookie = async (req: Request, res: Response) => {
res.status(200).json({ message: "Hello" });
};
when i click login theres no error, but i get no cookie either. I check it in mozilla devtools -> storage -> cookies, and there are test cookies, but no http only cookie. What is wrong? The server runs of 8000 port and frontend od 4200.
If client send a non encrypted and hashed password to server then attribute can be accessed by me. I should not access to that info. How can I prevent it?
I’m expecting not to access client plain text passwords because I can use that info to access other account systems. If I sell my app to another person that person can access his client password. That is wrong.
