Edit function in my code isn't working. I tried a few different methods but ended up getting the same error. The problem is with the edit function, but I can't figure it out. I am getting the error Uncaught TypeError: edit is not a function".
But I have defined the edit function. I tried adding this, but the edit gave me the same error.
The other functionalities like add and delete are working, but I am not able to edit my list of items. Please suggest a solution.
This is my javascript code:
const todoInput = document.querySelector(".todo-input");
const todoButton = document.querySelector(".todo-button");
const todoList = document.querySelector(".todo-list");
const filterOption = document.querySelector(".filter-todo");
//Event Listeners
document.addEventListener("DOMContentLoaded", getTodos);
todoButton.addEventListener("click", addTodo);
todoList.addEventListener("click", deleteTodo);
filterOption.addEventListener("click", filterTodo);
//Functions
function addTodo(e) {
//Prevent natural behavior
e.preventDefault();
//Create todo div
const todoDiv = document.createElement("div");
todoDiv.classList.add("todo");
//Create list
const newTodo = document.createElement("li");
newTodo.innerText = todoInput.value;
//Save to local - do this last
//Save to local
saveLocalTodos(todoInput.value);
//
newTodo.classList.add("todo-item");
todoDiv.appendChild(newTodo);
todoInput.value = "";
var edit = document.createElement('button');
edit.classList.add('edit');
edit.innerHTML = "EDIT";
edit.addEventListener('click', () => edit(e));
todoDiv.appendChild(edit);
//Create Completed Button
const completedButton = document.createElement("button");
completedButton.innerHTML = `<i class="fas fa-check"></i>`;
completedButton.classList.add("complete-btn");
todoDiv.appendChild(completedButton);
//Create trash button
const trashButton = document.createElement("button");
trashButton.innerHTML = `<i class="fas fa-trash"></i>`;
trashButton.classList.add("trash-btn");
todoDiv.appendChild(trashButton);
//attach final Todo
todoList.appendChild(todoDiv);
}
function edit(e){
const item = e.target;

const item = e.target;
if (item.classList[0] === "trash-btn") {

todo.addEventListener("transitionend", e => {

Try renaming the function to "OnEditPress".
You have a variable called "edit" as well as a function called "edit". Try using different names for these.
Assuming you have renamed the method to onEditPress, don't forget to pass the event object to your renamed edit method
edit.addEventListener('click', (e) => onEditPress(e));
