How to add a edit to-do list item feature?

Ive been studying javascript and following along on this online tutorial for a to-do list. I switched up and added a few of my own features, but I am not sure how would go about adding a feature where I can edit a individual list item?
I started off creating a function editTodo(key), I know I would have to append my new text to the old list text? If someone could give me a hint or guide me in the right direction?
//array that holds todo list items
let listItems = [];
//Function will create a new list item based on whatever the input value
//was entered in the text input
function addItem (text) {
const todo = {
text, //whatever user types in
checked: false, //boolean which lets us know if a task been marked complete
id: Date.now(), //unique identifier for item
};
//it is then pushed onto the listItems array
listItems.push(todo);
renderTodo(todo);
}
function checkDone(key) {
//findIndex is an array method that returns position of an element in array
const index = listItems.findIndex(item => item.id === Number(key));
//locates the todo item in the listItems array and set its checked property
//to opposite. 'true' will become 'false'
listItems[index].checked = !listItems[index].checked;
renderTodo(listItems[index]);
}
function deleteTodo(key) {
//find todo object in the listItems array
const index = listItems.findIndex(item => item.id === Number(key));
//create a new object with properties of the current list item
//delete property set to true
const todo = {
deleted: true,
...listItems[index]
};
//remove the list item from the array by filtering it out
listItems = listItems.filter(item => item.id !== Number(key));
renderTodo(todo);
}
//edits list item
function editTodo(key) {
//find todo object in the listItems array
const index = listItems.findIndex(item => item.id === Number(key));
}
//selects form element
const form = document.querySelector('.js-form');
const addGoal = document.getElementById('addBtn');
//adds a submit event listener
function selectForm(event) {
//prevent page refresh on form submission
event.preventDefault();
//select the text input
const input = document.querySelector('.js-todo-input');
//gets value of the input and removes whitespace beginning/end of string
//we then save that to new variable -> text
const text = input.value.trim();
//checks whether 2 operands are not equal, returning true or false (boolean)
//if input value is not equal to blank, add user input
if (text !== '') {
addItem(text);
input.value = ''; //value of text input is cleared by setting it to empty
input.focus(); //focused so user can add many items to list witout focusing the input
}
};
addGoal.addEventListener('click', selectForm, false);
form.addEventListener('submit', selectForm, false);
function renderTodo(todo) {
//saves local storage items, convert listItems array to JSON string
localStorage.setItem('listItemsRef', JSON.stringify(listItems));
//selects the first element with a class of 'js-to'list'
const list = document.querySelector('.js-todo-list');
//selects current todo (refer to top) list item in DOM
const item = document.querySelector(`[data-key='${todo.id}']`);
//refer to function deleteTodo(key)
if (todo.deleted) {
//remove item from DOM
item.remove();
return
}
//use the ternary operator to check if 'todo.checked' is true
//if true, assigns 'done' to checkMarked. if not, assigns empty string
const checkMarked = todo.checked ? 'done' : '';
//creates list 'li' item and assigns it to 'goal'
const goal = document.createElement('li');
//sets the class attribute
goal.setAttribute('class', `todo-item ${checkMarked}`);
//sets the data-key attribute to the id of the todo
goal.setAttribute('data-key', todo.id);
//sets the contents of the list item 'li'
goal.innerHTML = `
<input id="${todo.id}" type="checkbox" />
<label for="${todo.id}" class="tick js-tick"></label>
<span>${todo.text}</span>
<button class="edit-todo js-edit-todo"><i class="fa-solid fa-pencil"></i></button>
<button class="delete-todo js-delete-todo">X</button>
`;
//if item already exists in the DOM
if (item) {
//replace it
list.replaceChild(goal, item);
}else {
//otherwise if it doesnt (new list items) add at the end of the list
list.append(goal);
}
}
//selects entire list
const list = document.querySelector('.js-todo-list');
//adds click event listener to the list and its children
list.addEventListener('click', event => {
if (event.target.classList.contains('js-tick')) {
const itemKey = event.target.parentElement.dataset.key;
checkDone(itemKey);
}
//add this 'if block
if (event.target.classList.contains('js-delete-todo')) {
const itemKey = event.target.parentElement.dataset.key;
deleteTodo(itemKey);
}
})
//render any existing listItem when page is loaded
document.addEventListener('DOMContentLoaded', () => {
const ref = localStorage.getItem('listItemsRef');
if (ref) {
listItems = JSON.parse(ref);
listItems.forEach(t => {
renderTodo(t);
});
}
});

I added the edit feature to the event handler for click events on the list:
Figure I
if (event.target.matches('.edit-todo') && event.target !== event.currentTarget) {
const text = event.target.previousElementSibling;
text.toggleAttribute('contenteditable');
if (text.contenteditable) {
text.focus();
}
}
Basically, when the user clicks an edit button the contenteditable attribute is toggled (true/false) on the <span> that sits right before the button (hence .previousElementSibling).
I also added 2 CSS rulesets as well:
Figure II
.fa-pencil { pointer-events: none }
[contenteditable] { outline: 3px inset blue }
For some reason my mouse cannot click font-awesome icons, I have no idea why. So I disabled click events on the edit icon in order to click the edit button. Others might have the same problem as I do -- I'm 99% sure there's no harm in keeping that ruleset since it just makes the edit button 100% the origin element on the event chain. The second ruleset is a visual cue to the user that the <span> is editable.

Autocomplete Search bar won't read my values

im trying to make a search bar for my website to redirect pepole on other pages of my website by selecting values from autocomplete suggestions, but when i select a suggestion (example:"Home") and hit search nothing happends, instead when i write the value (example:"chat") it works just fine and it redirects me to another page, my question is: what im doing wrong and why my autocompleted values are not seen by the searchbar?
Here is the code example for values "chat, Home, youtube"
function ouvrirPage() {
var a = document.getElementById("search").value;
if (a === "chat") {
window.open("/index.html");
}
if (a === "Home") {
window.open("/customizedalert.html");
}
if (a === "youtube") {
window.open("https://www.youtube.com/");
}
}
And here is the entire thing:
https://codepen.io/galusk0149007/pen/LYeXvww

Try this in your IDE : Clicking the search icon will navigate to your urls.
// getting all required elements
const searchWrapper = document.querySelector(".search-input");
const inputBox = searchWrapper.querySelector("input");
const suggBox = searchWrapper.querySelector(".autocom-box");
const icon = searchWrapper.querySelector(".icon");
let linkTag = searchWrapper.querySelector("a");
let webLink;
let suggestions = ['chat','home', 'youtube']
// if user press any key and release
inputBox.onkeyup = (e)=>{
let userData = e.target.value; //user enetered data
let emptyArray = [];
if(userData){
icon.onclick = ()=>{
webLink = `https://www.google.com/search?q=${userData}`;
linkTag.setAttribute("href", webLink);
linkTag.click();
}
emptyArray = suggestions.filter((data)=>{
//filtering array value and user characters to lowercase and return only those words which are start with user enetered chars
return data.toLocaleLowerCase().startsWith(userData.toLocaleLowerCase());
});
emptyArray = emptyArray.map((data)=>{
// passing return data inside li tag
return data = `<li>${data}</li>`;
});
searchWrapper.classList.add("active"); //show autocomplete box
showSuggestions(emptyArray);
let allList = suggBox.querySelectorAll("li");
for (let i = 0; i < allList.length; i++) {
//adding onclick attribute in all li tag
allList[i].setAttribute("onclick", "select(this)");
}
}else{
searchWrapper.classList.remove("active"); //hide autocomplete box
}
}
function select(element){

inputBox.value = selectData;

Editing a specific row in a dynamic table

I've been stuck with this problem for a while now and almost got it to work, but I'm left with an issue I cannot solve or find a solution anywhere.
So I'm trying to make an application which helps users log certain data - it all works on a table, adding rows and deleting them works just fine, but I have a problem with editing them.
At the end of each row, there are 2 buttons - delete and edit.
Edit pops up a modal, which should (and it does as far as I know) display inputs with values read from a specific table row. When you do this for the first time after reloading it works fine, but afterward, if you have more than one table rows it just starts to clean up these tr's upon submitting an edit of a row.
There's clearly a problem with logic, and I just cannot solve it. Most likely it can be found in this block
Record.prototype.addRow = function(){
let newLog = document.createElement('tr');
newLog.setAttribute('id',idContainer);
idContainer++;
recordTable.appendChild(newLog);
//store values and add them to each td
let valueStorage = [this.time,this.latitude,this.longitude,this.heading,
this.speed,this.wind,this.sea,this.visibility,this.remarks];
for (let i=0; i<9;i++) {
let tableData = document.createElement('td');
newLog.appendChild(tableData);
tableData.textContent = valueStorage[i];
}
//add 2 buttons - delete and edit
let deleteBtn = document.createElement('button');
deleteBtn.setAttribute('class','new-record__delete-row-btn')
newLog.appendChild(deleteBtn);
let editBtn = document.createElement('button');
editBtn.setAttribute('class','new-record__edit-row-btn')
newLog.appendChild(editBtn);
//adding functionality to edit/delete btns
function editThisRow(e){
//on pop up display values from the edited row
let popUpHeading = document.querySelector('.new-record__popup h2');
let thisRow = e.target.parentNode;
let editStorage = [];
for(let i = 0; i < 9; i++){
editStorage.push(thisRow.childNodes[i].textContent);
}
editStorage[1]=editStorage[1].replace(/([A-Z])/,"");
editStorage[2]=editStorage[2].replace(/([A-Z])/,"");
for(let i = 0; i <8; i++){
newRecordInputs[i].value = editStorage[i];
}
remarks.value = editStorage[8];
popUpHeading.textContent = 'Edit your record!'
openNewRecordPopup();
//adding event listener to the record edit button, so that it applies changes
const recordEditBtn = document.querySelector('#edit-record')
newRecordSubmitBtn.style.display = "none";
recordEditBtn.style.display = "block";
recordEditBtn.addEventListener('click',()=>{
let thisRowTds = thisRow.childNodes;
for(let i = 0; i < 8; i++){
thisRowTds[i].textContent = newRecordInputs[i].value
}
thisRowTds[8].textContent = remarks.value;
closeNewRecordPopup();
popUpHeading.textContent = 'Fill out inputs below to make a new record';

quick note: This is not designed for mobile use, and I really would appreciate vanilla JS solutions, without lib's or frameworks.

All edit clicks keep on stacking in below button:
const recordEditBtn = document.querySelector('#edit-record')
I have changed it to have fresh event handler always like this:
let oldRecordEditBtn = document.querySelector('#edit-record')
let recordEditBtn = oldRecordEditBtn.cloneNode(true);
oldRecordEditBtn.parentNode.replaceChild(recordEditBtn, oldRecordEditBtn);
So now below snippet is working fine for your issue:
//Set ship header and type
const shipDetailsBtn = document.querySelector('.ship-details__button');
const shipDetailsClosingBtn = document.querySelector('#ship-details__popup-closing-btn');
const shipDetailsPopUp = document.querySelector('.ship-details__popup');
const shipTypeSpan = document.querySelector('#ship-type-span');
const shipNameSpan = document.querySelector('#ship-name-span');
//opening of a form
shipDetailsBtn.addEventListener('click', () => {
shipDetailsPopUp.style.visibility = "visible";
disableButtons();
})
//disabling of button operation when popup is open;
function disableButtons() {
voyageDetailsBtn.disabled = true;
newRecordBtn.disabled = true;
shipDetailsBtn.disabled = true;
}
function enableButtons() {
voyageDetailsBtn.disabled = false;
newRecordBtn.disabled = false;
shipDetailsBtn.disabled = false;
}
//closing of a form
shipDetailsClosingBtn.addEventListener('click', () => {
shipDetailsPopUp.style.visibility = "hidden";
enableButtons();
})
//pop up input selection
const shipTypeSelect = document.querySelector('#ship-type');
const shipDetailsPopUpSubmit = document.querySelector('#ship-details-submit-btn');
//Submitting of ship details
shipDetailsPopUpSubmit.addEventListener('click', () => {

})

Why isn't the string.length updating?

This is my first piece of code js done on my own. I am trying to have an input field to add items to the list and then if you press the button to generate code it will collect all the checked items and copy the text into another div.
Basically, my question is around two variables:
const list = listUl.children;
const listCopy = listUl.querySelectorAll('span');
Let say I have 4 items in the list. If I add a new item to the list I can see the list.length add this new item, it changes from 4 to 5.
But it doesn't happen with listCopy.length the value keeps being 4.
Why is it happening if lstCopy is inside of list?
How can I have listCopy updated too?
Here is my code:
const addItemInput = document.querySelector('.addItemInput');
const addItemButton = document.querySelector('.addItemButton');
const copyText = document.querySelector('.generateCode');
const listUl = document.querySelector('.list');
const list = listUl.children;
const listCopy = listUl.querySelectorAll('span');
const clonedCode = document.querySelector('.code p');
//FUNCTION: Generate value/items = Draggable, Checkbox, Remove button
const attachItemListButton = (item) => {
//Draggable
item.draggable = "true";
item.classList.add("list--item");
//Checkbox
let checkbox = document.createElement('input');
checkbox.type = 'checkbox';
checkbox.className = 'checkbox';
checkbox.name = "chkboxName1";
checkbox.value = "value";
checkbox.id = "id";
item.insertBefore(checkbox, item.childNodes[0] || null);
//Remove button
let remove = document.createElement('button');
remove.className = 'remove';
remove.textContent = 'x';
item.appendChild(remove);
};
for (let i = 0; i < list.length; i += 1) {
attachItemListButton(list[i]);
}
//Cloning code if there are checked items
copyText.addEventListener('click', () => {
let copyTextFromList = "";
for (let i = 0; i < listCopy.length; i += 1) {
if (listCopy[i].parentNode.querySelector("input:checked")) {
copyTextFromList += listCopy[i].textContent + ',';
}
}
clonedCode.innerHTML = copyTextFromList;
});
//Add item from the input field to the list
addItemButton.addEventListener('click', () => {
let li = document.createElement('li');
let span = document.createElement('span');
span.textContent = addItemInput.value;
listUl.appendChild(li);
li.appendChild(span);
attachItemListButton(li);
addItemInput.value = '';
});
//FUNCTION: Remove button
listUl.addEventListener('click', (event) => {
if (event.target.tagName == 'BUTTON') {
if (event.target.className == 'remove') {
let li = event.target.parentNode;
let ul = li.parentNode;
ul.removeChild(li);
}
}
});

There are two variants of NodeList, live and non-live ones. querySelectorAll returns a static NodeList that is not live. .children returns a live one (technically it returns an HTMLCollection but you can ignore this distinction for now).
To make listCopy be live as well, you could use listUl.getElementsByTagName('span')…
To select elements by their classes, use getElementsByClassName. There is no way (that I know of) to get a live collection with CSS or XPath (i.e. more complex) queries, though.

The problem is that const listCopy = listUl.querySelectorAll('span'); is initiated with the span array from the beginning.
In order to get updated list
const listCopy = listUl.querySelectorAll('span'); will be let listCopy = listUl.querySelectorAll('span'); and in your function
//Cloning code if there are checked items
copyText.addEventListener('click', () => {
// add the following line - in this way you will select the span from the updated list
listCopy = listUl.querySelectorAll('span');
let copyTextFromList = "";
for (let i = 0; i < listCopy.length; i += 1) {
if (listCopy[i].parentNode.querySelector("input:checked")) {
copyTextFromList += listCopy[i].textContent + ',';
}
}
clonedCode.innerHTML = copyTextFromList;
});

if you want to use querySelectorAll, this maybe help. with this every time you check the length it recalculates and returns the value. Symbol.iterator helps you to manipulate for...of loops.
const addItemInput = document.querySelector('.addItemInput');
const addItemButton = document.querySelector('.addItemButton');
const copyText = document.querySelector('.generateCode');
const listUl = document.querySelector('.list');
const list = listUl.children;
const listCopy = {
get length() {
return listUl.querySelectorAll('span').length
},
*[Symbol.iterator]() {
let i = 0;
const l = listUl.querySelectorAll('span');
while( i < l.length ) {
yield l[i];
i++;
}
}
};
const clonedCode = document.querySelector('.code p');
//FUNCTION: Generate value/items = Draggable, Checkbox, Remove button
const attachItemListButton = (item) => {

checkbox.type = 'checkbox';
checkbox.className = 'checkbox';
checkbox.name = "chkboxName1";
checkbox.value = "value";
checkbox.id = "id";
item.insertBefore(checkbox, item.childNodes[0] || null);

let remove = document.createElement('button');
remove.className = 'remove';

attachItemListButton(list[i]);

removing the input text in the text field that matches the removed tab

In this example I made, since it uses keyup event, each input text (separated by comma) entered is converted into a tab. I want the input text to be deleted from the text field according to the tab I remove; for example, I enter "Item 1" but I suddenly change my mind and decide to remove the "Item 1" tab, the input text in the text field that has a string that matches the textContent of the removed tab should be automatically deleted from the text field.
var query = document.querySelector.bind(document);
query('#textfield').addEventListener('keyup', addTag);
function addTag(e) {
var evt = e.target;
if(evt.value) {
var items = evt.value.split(',');
if(items.length <= 10) {
evt.nextElementSibling.innerHTML = null;
for(var i = 0; i < items.length; i++) {
if(items[i].length > 0) {
var label = document.createElement('label'),
span = document.createElement('span');
label.className = 'tag';
label.textContent = items[i];
span.className = 'remove';
span.title = 'Remove';
span.textContent = 'x';
label.insertAdjacentElement('beforeend', span);
evt.nextElementSibling.appendChild(label);
span.addEventListener('click', function() {
var currentElement = this;
currentElement.parentNode.parentNode.removeChild(currentElement.parentNode);
})
}
}
}
} else {
evt.nextElementSibling.innerHTML = null;
}
}

How can I make that feature possible?

Replace the 'x' button listener with this one:
span.addEventListener('click', function () {
var text_field = document.getElementById("textfield");
var evt = this.parentNode;
var tags = text_field.value;
this.parentNode.removeChild(this); // remove the 'x' span so you can get the pure tag text with .innerHTML
var evname = evt.innerHTML;
var tags_array = tags.split(",");
var tag_position = tags_array.indexOf(evname);
if(tag_position > -1)
tags_array.splice(tag_position,1);
text_field.value = tags_array.join(',');
evt.parentNode.removeChild(evt);
})
// Coding this complexity in pure javascript when there is jQuery is ... like eating soup with a fork. You will get the job done, but it is dammn hard!
