I have a form where the user inputs information from a book they are reading and upon hitting submit, the information is sent as its own object inside an array. I also have a forEach method running which loops through the array and displays each object as a div on the web page.
let myLibrary = [];
const book = {
title: title,
author: author,
pages: parseInt(pages),
read: false,
};
myLibrary.push(book)
As you can see from the code above, the three properties that the user fills out are the books title, author and page count. There's also a property that is automatically added called the read property and it is automatically set as false.
The Problem
My problem is this. I have the following code displayed at the bottom of each div.
<div class="read">
<label class="switch">
<input type="checkbox" />
<span class="slider round"></span>
</label>
</div>
This code is very simple. It's a toggle switch which I found here.
I want it so when the toggle switch is grayed out, the read status is set to false. But when the toggle switch is turned on, the read property is set to true. I am having a very difficult time figuring out how to get this done.
What I've Tried
I was able to use an onclick to select the toggle switch's parent element, and I tested it using console.log however I am unsure of where to go from there. I attempted to update the book.read to true using the ternary operator but it was out of scope and resulted in an error.
document.querySelector(".main").onclick = (ev) => {
let el = ev.target.classList.contains("switch")
? ev.target.parentElement
: ev.target.classList.contains("slider")
? ev.target
: false;
if (el) {
let toggle = el.parentElement.parentElement.parentElement;
let index = [...toggle.parentElement.children].indexOf(toggle);
myLibrary[index].read = false ? false : true;
console.log(myLibrary[index].read);
}
console.log(myLibrary);
};

Change this
function displayBook(book) {
...
<label class="switch" data-book="0">
to
function displayBook(book,bookIndex) {
...
<label class="switch" data-book="${bookIndex}">
and
myLibrary.forEach((book) => {
displayBook(book);
});
to
myLibrary.forEach((book,i) => {
displayBook(book,i);
});
lastly change
// Displays new book
displayBook(book);
to
// Displays new book
displayBook(book,myLibrary.length-1);
Here is the code inclusive a delete function
It would be slightly simpler if we had an associate array on book_id
Note I removed the numeric ID because it is not needed since the index of the array is the same
let myLibrary = [{
title: "The Once and Future King",
author: "White",
pages: 654,
read: false,
},
{
title: "The Hobbit",
author: "Tolkien",
pages: 304,
read: false,
},
];
const bookContent = document.getElementById("content");
const formDiv = document.getElementById("addBookForm");
function displayBook(book, idx) {
const addBook = document.createElement("div");
addBook.className = "book";
addBook.id = `book_${idx}`;
bookContent.appendChild(addBook);
addBook.innerHTML = `
<div class="title">
<p class="bookTitle">
<span>${book.title}</span>
</p>
</div>
<div class="body">
<p>
Author: <span>${book.author}</span>
</p>
<p>
Pages: <span>${book.pages}</span>

<div class="read">

<div class="delete">

</div>`;
}
// Display your original object list
myLibrary.forEach((book, i) => {
displayBook(book, i);
});
const deleteBook = (e) => {
const parent = e.target.closest("div.book");
const idx = parent.querySelector(".switch").dataset.book;
parent.remove();
console.log(idx);
myLibrary.splice(idx, 1);
console.log(myLibrary);
content.querySelectorAll("div.book").forEach((book, i) => { // reset the hard way
book.id = `book_${i}`;
book.querySelector("label.switch").dataset.book = i;
})
};
content.addEventListener("click", function(e) {
const tgt = e.target;
if (!tgt.matches(".delete-btn")) return; // not the delete
deleteBook(e); // pass the event to the delete
})
// Handle your object creation
const form = document.getElementById("form");
form.addEventListener("submit", updateLibrary);
function updateLibrary(event) {
// Need this so it doesn't refresh page
event.preventDefault();
const title = document.getElementById("title").value;

]2]2how can I prevent this from adding the same text each time the add favourite icon is clicked? It should just add it once and if the add favourite btn is selected again and the quote already exists it should not repeat adding the same ones. I tried a few stuff but as I am a beginner those did not work.
Please anyone can assist?

You can check for something before adding/pushing into favorites array.
Check if something like id(best) or string exists in the arrray and if so - return, else push

Step by step, this is what you are missing:
Create an empty object.
Each time the user clicks the "Add to Favourites" button, you should check if it's already in that object.
If it is, you are done handling that click event.
If it is not, you should add it to the object and then proceed with the logic you currently have to update the UI.
Simplified example:
const rollButton = document.getElementById('roll');
const numberElement = document.getElementById('number');
const addToFavouritesButton = document.getElementById('addToFavourites');
const favouritesElement = document.getElementById('favourites');
let number = null;
rollButton.addEventListener('click', () => {
numberElement.textContent = number = Math.floor(Math.random() * 10);
addToFavouritesButton.removeAttribute('disabled');
});
const favourites = {};
addToFavouritesButton.addEventListener('click', () => {
if (favourites[number]) return;
favourites[number] = true;
favouritesElement.textContent = Object.keys(favourites).sort((a, b) => a - b).join(', ');
if (Object.keys(favourites).length === 10) {
numberElement.textContent = '🎉';
rollButton.setAttribute('disabled', true);
addToFavouritesButton.setAttribute('disabled', true);
}
});

Local storage data not saving on page refresh

I am creating a settings portion on a website. I want the features chosen to be "saved" and kept when the page refreshes. I attempted this but it seems to just reset the form when I refresh the page. Another issue is when I click on the cancel button, the toggle buttons reset but the dropdown comes back blank instead of going back to the placeholder "select timezone". The issue most likely lies in my javascript code below. It's also throwing an error in stack overflow but works properly on my website (minus the issues described above). Any suggestions would be much appreciated!
// ---------- TOGGLE BTN ----------
const toggle = document.getElementsByClassName("toggle");
const labels = document.getElementsByClassName("labels");
for(let i=0; i < 2; i++) {
labels[i].innerHTML = "OFF";
toggle[i].addEventListener( "click", () => {
if(labels[i].innerHTML == "OFF") {
// console.log("button toggled");
labels[i].classList.add("on");
labels[i].innerHTML= "ON";
} else {
labels[i].classList.remove("on");
labels[i].innerHTML = "OFF";
}
});
}
// ---------- LOCAL STORAGE DATA ----------
const save = document.getElementById("save");
const cancel = document.getElementById("cancel");

const data = {

}
var emailVal = localStorage.getItem("email");
var privacyVal = localStorage.getItem("privacy");
var zoneVal = localStorage.getItem("timezone");
save.addEventListener('click', () => {
localStorage.setItem("email", emailBtn.value);

here a working example.
The problems with your code were that you were using emailBtn.value and publicBtn.value instead of emailBtn.checked and publicBtn.checked (they are checkbox so in order to get the correct value you have to read che checked property) and you were not loading the saved values on document load (the function inside window.addEventListener("load", ...) in my example.
Hope this helps you.

To see the iPhone better you should click on Full-Page in the snippet.
My problem was that I have 2 divs: #appsOne and #appsTwo which are in the div #slider. On the home page of the iPhone you can see two apps (#appsOne) and a text (#appsTwo) in the middle. The apps (#appsOne) should stay where they are but the text (#appsTwo) should be made on a second page with a horizontal scroll snap. How could I do that?
And here's an image, how it looks like without the slider and the #appsTwo div:

CSS Scroll-snapping
We can seperate the two 'screen's by wrapping each in a div with class panel.
To make the slider scrollable, we have to apply white-space: nowrap to force it into a single line. To make scroll-snap work horizontally, set scroll-snap-type to x and make it mandatory (scroll-snap-type: x mandatory;). This means that:
The visual viewport of this scroll container will rest on a snap point if it isn't currently scrolled. That means it snaps on that point when the scroll action finished, if possible. If content is added, moved, deleted or resized the scroll offset will be adjusted to maintain the resting on that snap point.MDN
We also set overscroll-behavior-x to contain which makes sure that no scroll chaining occurs to neighboring scrolling areas, e.g. underlying elements will not scroll.
We then apply scroll-snap-align: center to .panel. To prevent the overflowing contents in the panels, we also apply white-space: initial.
Result:
https://jsfiddle.net/Spectric/j7br8h5a/
JS Scroll-snapping (mouse drag)
We can take it one step further by adding support for user drag to scroll.
For this, we don't actually need scroll-snap at all. We can do it with pure JS.
Add an event listener for mousedown that sets isDown to true. Record the last position of the mouse.
Add an event listener for mousemove that checks whether the user is currently dragging (isDown == true). If the user is, calculate the distance from the current mouse position and the last mouse position, increment the slider's scrollLeft by the difference, and set the last position to the current position.
Add an event listener for mouseup that sets isDown to false and checks whether the slider's current scrollLeft is bigger than half. If it is, we can use scrollIntoView() on one panel to smoothly scroll it into the viewport.
To prevent scrolling when an app is opened, we can store the status in a variable which we set it to true when one of the open app function is called and false when the closeApp function is called. In the mousemove listener we also check whether this variable is true.

Strange behavior while adding DOM element using addEventListener() on a button

I'm trying to create a project card with user info when the user clicks on a button. When the user clicks the new project button, a modal form pops up that takes the user info and has a create button. The program should add a new project card whenever the user clicks the create button. To achieve this I added a click event listener to the Add new project button and another to Create button. I nested the create event listener inside the add new project event listener.
Here's the event listener.
addTileBtn.addEventListener("click", (e) => {
e.preventDefault();
modal.style.display = "block";
const titleField = document.querySelector("#title");
const descriptionField = document.querySelector("#description");
const create = document.querySelector("#create");
const close = document.querySelector("#close");
create.addEventListener("click", (e) => {
e.preventDefault();
title = titleField.value;
description = descriptionField.value;
function createProjectTile() {
const projectTile = document.createElement("div");
projectTile.classList.add("cards-grid__tile");
projectTile.textContent = title;
console.log(title, description);
return projectTile;
}
cardsGrid.appendChild(createProjectTile());
modal.style.display = "none";
});
close.addEventListener("click", (e) => {
e.preventDefault();
modal.style.display = "none";
});
});
The problem is that when I create the first card it works fine. But the second time, it creates two cards and 3 cards on the 3rd time and so on.
Here is the JSFiddle link for the full code.

I've edited your code, this should be what you wanted:
const logoutBtn = document.querySelector("#logout");
const addTileBtn = document.querySelector("#add-tile");
const cardsGrid = document.querySelector(".cards-grid");
const modal = document.querySelector(".modal");
const titleField = document.querySelector("#title");
const descriptionField = document.querySelector("#description");
const create = document.querySelector("#create");
const close = document.querySelector("#close");
addTileBtn.addEventListener("click", (e) => {
e.preventDefault();
modal.style.display = "block";
titleField.value = "";
descriptionField.value = "";
});
create.addEventListener("click", (e) => {
e.preventDefault();
title = titleField.value;
description = descriptionField.value;
function createProjectTile() {
const projectTile = document.createElement("div");
projectTile.classList.add("cards-grid__tile");
projectTile.textContent = title;
console.log(title, description);
return projectTile;
}
cardsGrid.appendChild(createProjectTile());
modal.style.display = "none";
});
close.addEventListener("click", (e) => {
e.preventDefault();
modal.style.display = "none";
});

scroll eventListener not working in javascript

window.addEventListener for scroll event is not working in my JS. I've tried several ways but still not working. I've used intersectionObserver in the JS also. Here is the JS code
const moveToAbout = () => {
document.getElementById('about').scrollIntoView(true)
}
const moveToWork = () => {
document.getElementById('work').scrollIntoView()
}
const moveToTop = () => {
document.getElementById('main-section').scrollIntoView(true)
}
const options = {
root: null,
threshold: 0,
rootMargin: "-150px"
}
const header = document.querySelector("header")
const sections = document.querySelectorAll(".section")
const mainSection = document.querySelector(".main-container")
const bttWrapper = document.getElementById('bttBtn-wrapper')
const veganImage = document.getElementById('vegan-store-image')
const navbar = document.getElementById('header')
veganImage.onclick = () => {
window.open("https://thoughtlessmind.github.io/Vegan-store")
}
const sectionOne = document.querySelector(".about-section");
// bttWrapper.style.display = 'none'
const mainObserver = new IntersectionObserver(function (entries, observer) {
entries.forEach(entry => {
if (entry.isIntersecting) {
header.classList.remove("nav-theme-2")
bttWrapper.classList.add("btnWrapperHidden")
bttWrapper.classList.remove("btnWrapperShow")
} else {
header.classList.add("nav-theme-2")
bttWrapper.classList.add("btnWrapperShow")
}
// console.log(entry.target, '-', entry.isIntersecting)
});
}, options);
mainObserver.observe(mainSection)
window.addEventListener("scroll", (event)=>{
console.log("scrolled")
var scroll = this.scrollY
if(scroll > 20){
console.log('reached')
}
})
const test = () =>{
console.log('working')
}
window.addEventListener("scroll", test)
window.addEventListener("scroll", () => console.log(window.pageYOffset));
Later in the lower part, I've tried to add scroll event in some ways but nothing is happening.

remove height property from CSS main. It is working now :
use min-height, max-height

}
const moveToTop = () => {

Try this one
const main = document.querySelector('main');
// main.onscroll = logScroll;
main.addEventListener('scroll', logScroll)
function logScroll(e) {
console.log(`Scroll position: ${e.target.scrollTop}`);
if(e.target.scrollTop == 761){
console.log('About Page is Reached');
}
}
Note for target.onscroll
Only one onscroll handler can be assigned to an object at a time. For greater flexibility, you can pass a scroll event to the EventTarget.addEventListener() method instead.
As explained here https://developer.mozilla.org/en-US/docs/Web/API/GlobalEventHandlers/onscroll
As I understand here in my code above, the target.scrollTop will only works when you have selected a valid target in your document object. In this case as I inspect your html markup you have wrapped your whole sections to a main tag.
Now that's it, I tried to get your main tag and add an eventListener to it, and it works to me. Hope this also works to you.
