Here is my script of to do list. I wanna add a new note to my ul list.
li > p > i, i, input :
var list = document.querySelector('.list');
document.querySelector('.add-btn').addEventListener('click', function(e){
e.preventDefault();
var input = document.querySelector('.add-input');
if(input.value !== '') {
var li = document.createElement('li');
firstP = document.createElement('p');
secondP = document.createElement('p');
firstIc = document.createElement('i');
secondIc = document.createElement('i');
input1 = document.createElement('input');
firstIc.className = 'fas fa-edit';
secondIc.className = 'fas fa-trash-alt';
input1.className = 'edit-note';
input1.setAttribute('type', 'text');
firstP.textContent = input.value;
secondP.appendChild(firstIc);
secondP.appendChild(secondIc);
li.appendChild(firstP);
li.appendChild(secondP);
li.appendChild(input1);
li.appendChild(li);
}
});
Here is HTML:
<div class='container'>
<h1>Note manager</h1>
<ul class="list">
<li>
<p>First note</p>
<p><i class="fas fa-edit"></i><i class="fas fa-trash-alt"></i></p>
<input type="text" name="" class="edit-note">
</li>
<li>
<p>Second note</p>
<p><i class="fas fa-edit"></i><i class="fas fa-trash-alt"></i></p>
<input type="text" name="" class="edit-note">
</li>
</ul>
<div class="add-notes">
<input type="text" name="" class="add-input" placeholder="Add a note..">
<button type="submit" class="add-btn"> Add</button>
</div>
</div>
And I wanna save added notes when I refresh the page. How can I do this ?
Should I use AJAX >?
Look at this line:
li.appendChild(li);
Here you add element as child of itself (of course it's not possible), looks like you want to do
list.appendChild(li);
instead.
EDIT:
Answer to your updated question: you should post your items to server and save them there or you can use localStorage to keep items in browser (link)

3)Be able to edit each item and save it when the edit button is clicked
Any help would be appreciated!

I'm working on a to-do list project and I got a problem, I want that when I click on the submit button the input value becomes a list item but it doesn't work.
here's the code:
let btn = document.getElementById('btn')
let txt = document.getElementById('txt')
btn.addEventListener('click', function(){
let list = document.createElement('li')
list.innerHTML = txt.value
})
<h1 id="title">To do list</h1>
<div class="main">
<input type="text" alt="type text here" id="txt">
<button type="submit" id="btn">Submit</button>
</div>
you forgot document.body.appendChild(list);
You need to have a ul (if it is to be an unordered list) element in your document - or to create one with JS, and then you need to add the new list items to that (not to the body).
Try this snippet (where the ul element is already in the document)
let btn = document.getElementById('btn')
let txt = document.getElementById('txt')
let ul = document.getElementById('ul');
btn.addEventListener('click', function() {
let list = document.createElement('li')
list.innerHTML = txt.value;
ul.appendChild(list);
})
<h1 id="title">To do list</h1>
<div class="main">
<input type="text" alt="type text here" id="txt">
<button type="submit" id="btn">Submit</button>
</div>
<ul id="ul">
</ul>
I'm trying to create an interactive resume template using javascript and html and have managed to use cloneNode to duplicate work history blocks (see attached screenshot)
The problem(s) I am having is that clicking on the add list item button in the cloned/duplicated work history block at the bottom, creates a <li> item in the 1st/cloned element.
The objective is to be able to add or delete ````` list elements within a specific work history block and to also be able to add/remove entire work history sections. Currently it deletes from the top down, which is also an issue.
Thanks for any pointers in advance.

You'd have to use e.currentTarget instead of document.getElementById, otherwise you're only referring to the first instance of it:
function addWork(e) {
const div = e.currentTarget.parentElement;
const cln = div.cloneNode(true);
document.getElementById("test").appendChild(cln);
}
function removeWork(e) {
const last = e.currentTarget.parentElement;
last.parentElement.removeChild(last);
}
function addTask(e) {
const ul = e.currentTarget.parentNode;
let task = ul.children[0].childNodes[1].value;
let li = document.createElement("li");
// Replace paragraph breaks
task = task.replace(/\r?\n|\r/g, " ");
li.innerText = task;
ul.appendChild(li);
}
function removeTask(e) {
const ul = e.currentTarget.parentNode;
ul.removeChild(ul.lastChild);
}

This allows you to refer to the specific element where the click event occurred and add/remove any elements that are relative within the DOM.
As a side note, it's best practice to have unique id attributes, adding the same id to multiple elements goes against that.
var add_button = $(".add_form_field");
var wrapper = $(".container1");
var max_fields = 9;
var x = 1;
$(add_button).click(function (e) {
e.preventDefault();
if (x < max_fields) {
x++;
$(wrapper).append(
` <div class="email">
<label for="">Year</label>
<input type="text" name="eduYear${x}">
<label for="">Title Name</label>
<input type="text" name="eduTitle${x}">
<label for="">Institution/School Name</label>
<input type="text" name="eduPlace${x}">
<label for="">Details</label>
<input type="text" name="eduNotes${x}"> <br>Delete<hr></div>`
); //add input box
}
});
$(wrapper).on("click", ".delete", function (e) {
e.preventDefault();
$(this).parent("div").remove();
x--;
});

I'm trying to add a menu page to my wordpress site for series script.
To easy understand "bolum" means episode and "sezon" means season.
Javascript
function addSeason() {
var main_div = document.getElementById("taxonamy-category");
var helper_son = document.getElementById("sezon-son");
var helper_active = document.getElementById("sezon-active");
var last_active = document.getElementById("sezon-" + helper_active.getAttribute("value"));
var ul = document.getElementById("sezon-tabs");
var yeni_sezon = parseInt(helper_son.getAttribute("value"), 10) + 1;
var li = document.createElement("li");
var a = document.createElement("a");
var last_div = document.getElementById("bolumler-" + yeni_sezon - 1);
var div = document.createElement("div");
var a2 = document.createElement("a");
a2.appendChild(document.createTextNode(" + Yeni Bölüm Ekle"));
a2.setAttribute("id", "bolum-add");
a2.setAttribute("onclick", "return addBolum();");
a2.setAttribute("class", "taxonamy-add-new");
div.setAttribute("id", "bolumler-" + yeni_sezon);
div.setAttribute("class", "tabs-panel");
div.setAttribute("style", "display:block;");
last_div.setAttribute("style", "display:none;");
div.appendChild(a2);
main_div.appendChild(div);
a.appendChild(document.createTextNode("Sezon " + yeni_sezon));
a.setAttribute("href", "#sezon-" + yeni_sezon);
a.setAttribute("id", "sezon");
a.setAttribute("onclick", "return focusSeason();");
li.setAttribute("id", "sezon-" + yeni_sezon);

li.appendChild(a);
ul.appendChild(li);
last_active.removeAttribute("class");
helper_active.setAttribute("value", yeni_sezon);
helper_son.setAttribute("value", yeni_sezon);
}

and these 2 hidden elements on my html for storing last season etc.
<input type="hidden" name="sezon-son" id="sezon-son" value="1" />
<input type="hidden" name="sezon-active" id="sezon-active" value="1" />
This js function has no effect i'm checking it with chrome.Has anyone know the problem ?
Thanks so much
First of all, you have id dublicate:
<li id=sezon-active> and <input id=sezon-active>
Also, "bolumler-"+yeni_sezon-1 equals NaN, it should be "bolumler-"+(yeni_sezon-1).
You should rename <a id="sezon" ... to <a id="sezon-1" also to make your code work without errors.
Some more fixes made, here is working code:

I am attempting to make a todo list.Not too sure why my code isn't working.Trying to get the value from the add item input to the To-Do ul.
HTML
<body>
<div class = 'container'>
<h3> Add Item </h3>
<input id='newTask' type='text'> <button id='addTaskButton'> Add </button>
<h3> To-Do </h3>

<li> <input type='checkbox' checked> <label> Buy Peanut Butter </label> <button class='delete'> Delete </button> </li>
</ul>
</div>
<script src = "todolist.js" type="text/javascript"></script>
</body>
Javascript
var taskInput = document.getElementById('newTask');
var addTaskButton = document.getElementById('addTaskButton');
var incompleteTasks = document.getElementById('toDo');
var completedTask = document.getElementById('completedTasks');
var addTask = function () {
var text = taskInput.value;
var li = '<li>' + text + '<li>';
incompleteTasks.appendChild(li);
}
addTaskButton.onclick = addTask;
Any help is greatly appreciated.
Thanks
appendChild accepts a DOMElement, not a string. You need to create an element first and then append it:
var addTask = function () {
var text = taskInput.value;
var li = document.createElement('li');
li.innerHTML = text;
incompleteTasks.appendChild(li);
}
