I want to create a Browser like home page where the user can add links shortcuts like in opera mini or chrome. [And that shortcuts they created should only appear on their pages]
So how can I let my website visitors to add their own links in my page where only they can see the links created them!
Thank you!
If you want to use an HTML element in vanilla JavaScript without using a function like Document.createElement(), you need to use it like this:
const App = `<h1>Hello, world</h1>`;
But is there a way to do this in vanilla JavaScript, just HTML tags without a string declaration (signs like “)? For example:
const App = <h1>Hello, world</h1>;
I have two component where I am rendering images and links from a data js file. I would also like to generate a paragraph but am unsure where I can call the paragraph tag to generate it on both my ProjectList.js and Project.js components.
I’d like it to be just under the image.
Project.js
import "./project.css";
const Project = ({ img, link }) => {
return (
<div className="p">
<div className="p-browser">
<div className="p-circle">Tick</div>
<div className="p-circle"></div>
<div className="p-circle"></div>
</div>
<a href={link} target="_blank">
<img src={img} alt="" className="p-img" />
<p>kscjksnkdjs</p>
</a>
<div className="p-right">
<div className="p-bg"></div>
</div>
</div>
);
};
export default Project;
ProjectList.js
import "./projectList.css";
import Project from "../project/Project";
import { projects } from "../../data";
const ProjectList = () => {
// console.log(projects);
return (

async function editBackEnd() {

}I’m trying to update certain fields in an array in firestore. I know there is no direct way to do so but with this code i am able to access the field but it removes all the other entries/fields.
How do I make sure it only updates the field that i want. in this cause im just trying to update payment of index 0
Im having issues uploading pics to stackoverlow so here’s a couple url

Some questions about Feedback:
as the title asked
A slot site that only encounters objects of a single hidden class is called monomorphic; if it encounters objects of two hidden classes, it is called polymorphic; if it is greater than 2, it is called megamorphic. Is that right? Then does the slot size have anything to do with polymorphic?
As the content increases, the size of the text will decrease, so that the text is always within the area and will not overflow

I want to make a background animation wave like this website hero section. https://raze.network/
Could anyone help me to make this animation background wave?
Thank you 🙂
Before starting, sorry if this is a very elemental question and if I’m missing something basic. I’m trying to create a three tier app in which users can create and consult purchase orders. So far everything is working, except for some methods that I have to update information on orders. When I click the “Update”, “Delete” or “Complete Status” buttons in the front end, I should get a message saying “The order was successfully updated!”, but instead, nothing happens and I get this error in my Java back end:
Failed to convert value of type 'java.lang.String' to required type 'long'; nested exception is java.lang.NumberFormatException: For input string: "undefined"]
Here is all the relevant code that I have for the back end:
Order Model
package com.backend.springjwt.models;
import javax.persistence.*;
@Entity
@Table(name = "orders")
public class Order {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "ordid_generator")
@SequenceGenerator(name = "ordid_generator", initialValue = 10000, allocationSize = 1, sequenceName = "ordid_seq")
private long id;
@Column(name = "title")
private String title;
@Column(name = "description")
private String description;
@Column(name = "completed")
private boolean completed;
@Column(name = "userid")
private String userId;
public Order() {
}
public Order(String title, String description, boolean completed, String userId) {
this.title = title;
this.description = description;
this.completed = completed;
this.userId = userId;
}
Order Controller
@PutMapping("/orders/update/{id}")
@PreAuthorize("hasRole('ADMIN')")
public ResponseEntity<Order> updateOrder(@PathVariable("id") long id, @RequestBody Order order) {
Optional<Order> orderData = orderRepository.findById(id);
if (orderData.isPresent()) {
Order _order = orderData.get();
_order.setTitle(order.getTitle());
_order.setDescription(order.getDescription());
_order.setCompleted(order.isCompleted());
_order.setUserId(order.getUserId());
System.out.println(order.getId());
System.out.println(order.getDescription());
System.out.println(order.getUserId());
return new ResponseEntity<>(orderRepository.save(_order), HttpStatus.OK);
} else {
return new ResponseEntity<>(HttpStatus.NOT_FOUND);

I’ve been looking at everything for hours and I can’t quite figure out what’s wrong. Since the only long value in the orders table is the id for the order, that must be the issue, but I’ve tried to get the id as a String and then parse it to be long, but I get the same error. Any insight is appreciated.
I am trying to show an icon when i double click an element. Here is my project
https://codesandbox.io/s/brave-herschel-s092nm
I know there is one option to create another component, but I think that is not necessary, because it is just a single icon i want to change, is there another simpler way to change the state ?

<button id = "sunButton" onclick="sunPausePlayToggle()">PLAY/PAUSE</button
sunPausePlayToggle() is a function in JS which will control the animation .

CSS code:
I am using keyframe animations to animate the sun and sky.
@keyframes risesky {

}
50% {

}
#sunSky {
height: 500px;
overflow: hidden;
animation: sky 11s infinite both;
}
Javascript code:
here is the problem I am getting, I can only pause the animation in JS ,but can’t play.
function sunPausePlayToggle(){
document.getElementById("sunSky").style.animationPlayState = "paused";
document.getElementById("sun").style.animationPlayState = "running";
}
I am a novice in this and it is really making me to lose my hair; I can find what I’m doing wrong, please help. I am doing this in javascript. It doesn’t show any error, nor display any result either. This is what I have:
var sumIt;
var subtractIt;
var multiplyIt;
var divideIt;
var operatorOpt = prompt("Select operator");
function showResult(whatResult) {
document.write(whatResult);
document.write("<br>");
}
var doSomething = function(num1, num2) {
if (operatorOpt == sumIt) {
showResult("The result is: " + (num1 + num2));
} else if (operatorOpt == subtractIt) {
showResult("The result is: " + (num1 - num2));
} else if (operatorOpt == multiplyIt) {
showResult("The result is: " + (num1 * num2));
} else if (operatorOpt == divideIt) {
showResult("The result is: " + (num1 / num2));

On Backend , i will compare email id and password with the encrybted password and get the user if it exsists with given credentials, and attched jwt token with userid .
exports.loginUser = async (req, resp) => {
console.log("login Req body : ", req.body);
// user login
try {
const email=req.body.email;
const password=req.body.password;
const user= await User.login(email,password);
const token=createToken(user._id)
resp.cookie('jwt',token);
resp.status('200').json({id:user._id})
} catch (error) {
if(error)
{
console.log(error.message);
resp.status('400').json({message:error.message})
}
}
}But I login user with my front end I didn’t receive any JWT token But when i test my
API using POSTMAN it shows JWT token

Hi I need some help with these it says that
Uncaught (in promise) TypeError: Object(…)(…).once is not a function
at eval (store.js?07a4:42:1)
at eval (index-6de4cbb9.js?4d2d:2453:1)
Here’s my code:
onAuthStateChanged(firebaseAuth, user => {
if (user) {
// User is signed in, see docs for a list of available properties
// https://firebase.google.com/docs/reference/js/firebase.User
const userId = firebaseAuth.currentUser.uid
ref(firebaseDb, 'users/' + userId).once('value', snapshot => {
console.log('snapshot: ', snapshot)
})
// ...
} else {
// User is signed out
// ...
}
})
Within the code.org javascript editor for the applab, there is the ability to create a dropdown by creating a dropdown by:
dropdown('id', 'option1', 'option2', ...);
I would like to know if there is a way to edit the list, treating it something like an array:
remove('id', 'position');
and:
insert('id', 'position', 'item1', 'item2'...);
any help would be appreciated, as I can’t find any way to do this in other places.
I have a boostrap 5.1.3 modal with some content, by default if the content is biger of 400px for the modal, a scrollbar should appear.
But this does not happen and only works after clicking the scroll down button.
If someone has an idea of the problem ?
refreshScroll();
const exampleModal = document.getElementById('exampleModal')
if(exampleModal){
exampleModal.addEventListener('show.bs.modal',refreshScroll )
}
var objDiv = document.getElementById("pmbox");
objDiv.scrollTop = objDiv.scrollHeight;
document.querySelector('#pmsend').addEventListener('click', function (e) {
e.preventDefault();
refreshScroll();
});
function refreshScroll(){
var objDiv = document.getElementById("pmbox");
if(objDiv)
objDiv.scrollTop = objDiv.scrollHeight;
