I am trying to create a "library" where you can add books by yourself and they also get a "remove" button that removes the book and a "change status" button that changes the status of the book has been read or not.
Everything works fine except the "change status" button, which only lets the user change the status of every other book. for example if you add 4 books you would only be able to change book 2 and 4, if you add 5 books you can only change books 1,3,5 instead of working for all of them.
const myLibrary = [];
function Book(title, author, pages, read) {
this.title = title;
this.author = author;
this.pages = pages;
this.read = read;
}
// Prototype functions
Book.prototype.info = function() {
return `${this.title} by ${this.author}, ${this.pages} pages, ${this.read}`;
};
Book.prototype.changeStatus = function() {
if ((this.read) == 'Already read') {
this.read = 'Haven\'t read yet';
} else if ((this.read) == 'Haven\'t read yet') {
this.read = 'Already read';
}
}
// Add a new book to the array
function addBookToLibrary(title, author, pages, read) {
const newBook = new Book(title, author, pages, read);
myLibrary.push(newBook);
}
// Examples
addBookToLibrary('Title', 'Author', 251, 'Already read');
addBookToLibrary('The book', 'John Smith', 511, 'Already read');
addBookToLibrary('Rich quick', 'Robert', 2541, 'Haven\'t read yet');
addBookToLibrary('How to code', 'Odin', 221, 'Already read');
const books = document.querySelector('.books');
// Display examples for testing
for (let i = 0; i < myLibrary.length; i++) {
console.log(myLibrary[i].info());
const container = document.createElement('div');
books.appendChild(container);
const div = document.createElement('div');
div.textContent = myLibrary[i].info();
container.appendChild(div);
}
// Display submitted books

}
const form = document.querySelector('form');
form.style.display = "none"
// Event handler for new book button
function toggleFormOn() {

function toggleFormOff(event) {

})

<li>
<select name="bookRead" id="bookRead">

<option value="Haven't read yet">Didn't read</option>
</select>
</li>
<li class="btn">
<button type="submit" id="sub">Submit</button>
</li>
</ul>
</form>
I tried changing a lot of stuff: tweaking the html structure, modifying the createChanger() and also displayBooks(). Nothing seems to work since I can't identify the issue that is causing it to only change every other book and not every single book.

I'm currently making a Library project, and I made it so that each book entered is stored in an array (in this case, the array is myLibrary). Then I made it so that each book in the array creates a new div with the class of "card." I've implemented a "Remove Button" for each card, but I'm not sure as to how I can make the button delete the book from the array. Any help would be appreciated, thank you.
I've tried
const remBtn = document.createElement("button");
card.appendChild(remBtn);
remBtn.textContent = "Remove";
remBtn.onclick = remBook;
// Remove book function
function remBook() {
const findBook = myLibrary.findIndex((element) => element === book);
const delBook = myLibrary.slice(findBook, 1);
}
Here are my codes:

let card = document.createElement("div");
card.classList.add("card");
currentDisplay.appendChild(card);
for (let key in myLibrary) {
const text = document.createElement("p");
text.textContent = `${key}: ${myLibrary[key]}`;
card.appendChild(text);
}
const readBtn = document.createElement("button");
card.appendChild(readBtn);
if (myLibrary.read === true) {
readBtn.textContent = "Read";
}
if (myLibrary.read === false) {
readBtn.textContent = "Not Read";

});
}
// Remove book function
function remBook() {
const findBook = myLibrary.findIndex((element) => element === book);
const delBook = myLibrary.slice(findBook, 1);
}
displayBooks();
First let's give each Book object a unique property.
// Object constructor
function Book(title, author, page, read) {
this.bookId = `book${++Book.id}`;
this.title = title;
this.author = author;
this.page = page;
this.read = read;
}
//static property
Book.id = 0;
While rendering a book we use the bookId property as class name for the div. This will be used for deleting the element.
card.classList.add(`${myLibrary.bookId}`);
Inside remove book function, we find the book using bookId property. we use the splice method to remove an element from array. Then we call the remove method on div element to delete the div.
// Remove book function
function remBook() {
const bookId = this.parentElement.classList[1];
const findBook = myLibrary.findIndex(
(element) => element.bookId === bookId
);
const delBook = myLibrary.splice(findBook, 1);
this.parentElement.remove();
}
// Data inputs
let myLibrary = [{
title: 'test',
author: 'test',
page: '123',
read: true,
}, ];
// Object constructor
function Book(title, author, page, read) {
this.bookId = `book${++Book.id}`;
this.title = title;
this.author = author;
this.page = page;
this.read = read;
}
//static property
Book.id = 0;
// Add new books to library
function addBookToLibrary() {
let a = document.getElementById('formTitle').value;
let b = document.getElementById('formAuthor').value;
let c = document.getElementById('formPage').value;
let d = document.getElementById('formRead').checked;
if (a !== '' && b !== '' && c !== '') {
myLibrary.push(new Book(a, b, c, d));
}
}
const submit = document.getElementById('submitInput');
submit.addEventListener('submit', () => {
event.preventDefault();
addBookToLibrary();
submit.reset();
displayBooks();
});
// Display each book as cards
function displayBooks() {
const currentDisplay = document.querySelector('.currentDisplay');
currentDisplay.textContent = '';
myLibrary.forEach((myLibrary) => {
let card = document.createElement('div');
card.classList.add('card');
card.classList.add(`${myLibrary.bookId}`);
currentDisplay.appendChild(card);
for (let key in myLibrary) {
const text = document.createElement('p');
text.textContent = `${key}: ${myLibrary[key]}`;
card.appendChild(text);
}
const readBtn = document.createElement('button');
card.appendChild(readBtn);
if (myLibrary.read === true) {
readBtn.textContent = 'Read';
}
if (myLibrary.read === false) {
readBtn.textContent = 'Not Read';
}
readBtn.addEventListener('click', () => {
if (readBtn.textContent === 'Read') {
readBtn.textContent = 'Not Read';
myLibrary.read = false;
} else if (readBtn.textContent === 'Not Read') {
readBtn.textContent = 'Read';
myLibrary.read = true;
}
});
const remBtn = document.createElement('button');
card.appendChild(remBtn);
remBtn.textContent = 'Remove';
remBtn.onclick = remBook;
});
}
// Remove book function
function remBook() {
const bookId = this.parentElement.classList[1];
const findBook = myLibrary.findIndex(
(element) => element.bookId === bookId
);
const delBook = myLibrary.splice(findBook, 1);
this.parentElement.remove();
}
displayBooks();

I think you can add specific ids whenever you add a new card. And call the card classes using querySelectorAll. That will return you a nodelist. Loop that nodelist and check if the specific id that you are click right now match with the looped element's id. If true, you can do your stuffs in that loop cuz whatever you're doing will only apply to the button that you're clicking.
I made a sample here. By the way, I used JSON to check the condition in string state.
function remBook(obj) {
let card = document.querySelectorAll(".card");
for(let x=0; x<card.length; x++) {
if(JSON.stringfy(card[y].id) === JSON.stringfy(obj.id) {
/* You can do your stuff here using index */
}
}
}

What I am trying to achieve is the following with my code:
User input is printed on created task?
currently, as it stands, the user input is not printed and I am not sure how to achieve that.
How to make it that when the checkbox is ticked the word is strikethrough with a line?
I know if I do
if(checkbox) {element.style.textDecoration ="line-through"
but I am not sure how to call the element
How to make the list local storage?
I know the local storage is saves on the browser, but I am not sure where to put the local storage in this code that I wrote.

You can find the version where it is running here - https://jsfiddle.net/blaze92/seLvzd1h/
TO ANSWER ONE QUESTION AT A TIME
To achieve the strike through
Create a separate function for that and run it every time you add new element as follows
function Listen(){
var allCheckboxes=document.querySelectorAll('.tick')
allCheckboxes.forEach(checkbox=>{
checkbox.addEventListener('change',(e)=>{
var parentElem=e.target.parentElement
if(e.target.checked){
parentElem.style.textDecoration ="line-through"
}else{
parentElem.style.textDecoration ="none"
}
})
})
}
Then you can call the listen() function
At the bottom of createTask() after The append statement

Other stack answers have failed to fix my problem because I think this occurs for different reasons. My JS code:

const draggable_list = document.getElementById('draggable-list'); //draggable_list is a ul
let itemBox;
let items;
const array = [];
const listItems = [];
let dragStartIndex;
class item {
constructor(itemName) {
this.createDiv(itemName);
}
createDiv(itemName) {
let removeButton = document.createElement('button');
removeButton.innerHTML = 'REMOVE';
removeButton.classList.add('removeButton');
draggable_list.appendChild(items);
items.appendChild(removeButton);
removeButton.addEventListener('click', () => this.remove(items);
}
async remove(item, value) {
draggable_list.removeChild(item)
}
}
async function check() {
if (input.value != '') {
array.push(input.value)
listItems.push(input.value)
array.forEach((numbers,index) => {
items = document.createElement('li')
items.setAttribute('data-index', index)
items.innerHTML = `
<div class="draggable" draggable="true">

<i class="fas fa-grip-lines"></i>
</div>`;
} )
new item(input.value)
input.value = ''
}
addButton.addEventListener('click', check)
When remove() is called for the first time, it successfully removes the last li element. But when it is called again, I get the following error:
Uncaught (in promise) DOMException: Node.removeChild: The node to be removed is not a child of this node

Instead of copying and pasting some convoluted code you don't understand you should try and write it yourself. Try and focus on what you require and nothing else.
Here is one way of doing it:
const [inp,btn,ul]=["input","button","ul"].map(e=>document.querySelector(e));
btn.onclick=function(){
ul.innerHTML+=`<li><p>${inp.value}</p><button>delete</button></li>`;
inp.value="";
}
ul.onclick=function(ev){
if (ev.target.tagName==="BUTTON")
ul.removeChild(ev.target.closest("li"));
}
<input type="text">
<button>add</button>

I am creating a Todo list and trying to implement it with the following contents.
https://gyazo.com/0b47106078622a1e44e912f56b5e9603
-Show/hide depending on task status
-Toggle task display depending on radio button selected
-If you add a new task when "Working" is selected, the task will be displayed
-If you add a new task when "Complete" is selected, the task will not be displayed (but it is added correctly in the background)
■ Current problems
(1) If you press the task completion button and then put the check box into operation, "Only the completion button" will be hidden.
→I want to hide every td
(2) Even if you click the in-process button and then click the completion check box, it will not be hidden
■ Tried
if (createButton.textContent === "Working") {
createButton.textContent = "Done";
const doneParent = a.target.parentNode;
doneParent.className ='workDone'; /* Done class */
Here is this.parentNode;
I changed it to
If you have any other problems, please let me know.
Thank you for your guidance.
I'm creating a CRUD page where the user can add, delete and edit text, but I have an issue in updating the text after I select it for edit.
In editText function when I click the edit button the text that was added will pop up inside the input field. When I click on the update button (triggering the updateText function), I can see the text in console log but the corresponding html is not updated.
HTML
<div class="main">
<form>
<input type="text" placeholder="search">
</form>
<ul></ul>
<div>
<input class="add-text" type="text" placeholder="Add Text">
<button id="add">Add</button>
<button id="update">update</button>
</div>
</div>
Javascript
const inputsearch = document.querySelector('form input');
const addInputBtn = document.querySelector('#add');
const update = document.querySelector('#update');
addInputBtn.addEventListener('click', addtext);
function addtext(){
let li = document.createElement('li');
let inputadd = document.querySelector('.add-text');
let addedtext = inputadd.value;
let h1Tag = '<h1 id="text">'+addedtext+'</h1>';
let tags = h1Tag + '<button id="delete">Delete</button><button id="edit">Edit</button>';
if(addedtext == ''){
alert('please add some text');
return;
}else{
li.innerHTML = tags;
document.querySelector('ul').appendChild(li);
}
li.querySelectorAll('#delete')[0].addEventListener('click', deleteText);
li.querySelectorAll('#edit')[0].addEventListener('click', editText);
getlist(li, h1Tag);
inputadd.value = '';
}
function deleteText(e) {
e.target.parentNode.remove();
document.querySelector('.add-text').value = '';
}
function editText(e) {
let currentText = e.target.parentNode.firstChild.textContent;
let currentValue = document.querySelector('.add-text');
currentValue.value = currentText;
getupdate(currentText, currentValue);
}
function getupdate(currentText, currentValue) {
update.addEventListener('click', updateText);
function updateText() {
currentText = currentValue.value
console.log(currentText = currentValue.value);
}
}
function getlist(li, h1Tag) {
inputsearch.addEventListener('keyup', serchText);
function serchText(e) {
let typetext = e.target.value.toLowerCase();
if(h1Tag.toLowerCase().indexOf(typetext) != -1){
li.style.display = 'block';
}else{
li.style.display = 'none';
}
}
}
To solve the issue without changing your overall approach, your edit button click needs to get the corresponding element (not just its textContent) and pass it to your getupdate() function to be updated when your update button is clicked. Relatively minor changes to your current functions:
function editText(e) {
const currentText = e.target.parentNode.firstChild;
const currentValue = document.querySelector('.add-text');
currentValue.value = currentText.textContent;
getupdate(currentText, currentValue);
}
function getupdate(currentText, currentValue) {
update.addEventListener('click', updateText);
function updateText() {
currentText.textContent = currentValue.value;
}
}
There are some other issues with your code, particularly the creation of multiple elements with the same id (which is malformed and will likely become problematic as you add additional features). Following is a snippet that addresses that issue as well as simplifying some of your functions and fixing the search.
const search = document.querySelector('form input');
const input = document.querySelector('.add-text');
const container = document.querySelector('ul');
let items = null;
let currentItem = null;
const searchItems = (event) => {
if (items) {
const s = event.currentTarget.value.toLowerCase();
for (const item of items) {
if (item.firstChild.textContent.toLowerCase().indexOf(s) !== -1) {
item.style.display = 'block';
} else {
item.style.display = 'none';
}
}
}
};
const deleteItem = (event) => {
currentItem = null;
event.currentTarget.parentNode.remove();
};
const editItem = (event) => {
currentItem = event.currentTarget.parentNode.firstChild;
input.value = currentItem.textContent;
};
const updateItem = () => {
if (currentItem) {
currentItem.textContent = input.value;
}
};
const addItem = () => {
let val = input.value
if (val) {
const li = document.createElement('li');
let inner = '<h1 class="text">' + val + '</h1>';
inner += '<button class="delete">Delete</button>';
inner += '<button class="edit">Edit</button>';
li.innerHTML = inner;
container.appendChild(li);
val = '';
currentItem = li.firstChild;
items = document.querySelectorAll('li');
for (let del of document.querySelectorAll('.delete')) {
del.addEventListener('click', deleteItem);
}
for (let edit of document.querySelectorAll('.edit')) {
edit.addEventListener('click', editItem);
}
} else {
alert('please add some text');
return;
}
};
search.addEventListener('keyup', searchItems);
document.querySelector('#add').addEventListener('click', addItem);
document.querySelector('#update').addEventListener('click', updateItem);
<div class="main">
