i am creating a to-do list, i want the user to be able to edit and delete the added tasks, this will be possible by removing readonlyattribute from HTML. but i am struggling doing the edit function.
Here is my code:
const formulario=document.getElementById("new-task-form");
const lista=document.getElementById("list");
const input=document.querySelector("#new-task-input");
let id=0;
formulario.addEventListener('submit', (e)=>{
//console.log("activado");
e.preventDefault();
addTask();
});
let addTask=()=>{
id ;
let task=input.value;
lista.innerHTML =`<div id="tasks">
<div id="taskin">
<div id="${id}">
<input
id="${id}"
type="text"
value=${task}
readonly
/>
</div>
<div >
<button >Edit</button>
<button >Delete</button>
</div>
</div>
</div> `
input.value='';
}
lista.addEventListener('click', (evento)=>{
console.log(evento);
if(evento.target.className=="edit"){
console.log("Editar");
}else if(evento.target.className=="delete"){
console.log("Borrar");
}
}) <body>
<header>
<h1>Task List</h1>
<form action="#" id="new-task-form"> <!--Formulario para poner tareas-->
<input type="text" id="new-task-input" placeholder="Que vas a hacer" />
<input type="submit" id="new-task-submit" value="Add Task" />
</form>
</header>
<main>
<div id="list" >
<h2>Tasks</h2>
<div id="tasks">
<!-- <div >
<div >
<input type="text"
value="My Task"
readonly
/>
</div>
<div >
<button >Edit</button>
<button >Delete</button>
</div>
</div> -->
</div>
</div>
</main>
<script src="app.js"></script>.
</body>
</html>Thanks in advance :D

I have added some lines to your JS code. Please check.
lista.addEventListener('click', (evento)=>{
let parentEl = evento.target.parentNode.parentNode;
let input = parentEl.getElementsByTagName('input');
if(evento.target.className=="edit"){
console.log("Editar");
input[0].removeAttribute('readonly');
}else if(evento.target.className=="delete"){
console.log("Borrar");
}
})
Test it in the Snippet below:
const formulario=document.getElementById("new-task-form");
const lista=document.getElementById("list");
const input=document.querySelector("#new-task-input");
let id=0;
formulario.addEventListener('submit', (e)=>{
//console.log("activado");
e.preventDefault();
addTask();
});
let addTask=()=>{
id ;
let task=input.value;
lista.innerHTML =`<div id="tasks">
<div id="taskin">
<div id="${id}">
<input
id="${id}"
type="text"
value=${task}
readonly
/>
</div>
<div >
<button >Edit</button>
<button >Delete</button>
</div>
</div>
</div> `
input.value='';
}
lista.addEventListener('click', (evento)=>{
let parentEl = evento.target.parentNode.parentNode;
let input = parentEl.getElementsByTagName('input');
console.log(input[0]);
if(evento.target.className=="edit"){
input[0].removeAttribute('readonly');
console.log("Editar");
}else if(evento.target.className=="delete"){
console.log("Borrar");
}
})<body>
<header>
<h1>Task List</h1>
<form action="#" id="new-task-form"> <!--Formulario para poner tareas-->
<input type="text" id="new-task-input" placeholder="Que vas a hacer" />
<input type="submit" id="new-task-submit" value="Add Task" />
</form>
</header>
<main>
<div id="list" >
<h2>Tasks</h2>
<div id="tasks">
<!-- <div >
<div >
<input type="text"
value="My Task"
readonly
/>
</div>
<div >
<button >Edit</button>
<button >Delete</button>
</div>
</div> -->
</div>
</div>
</main>
<script src="app.js"></script>.
</body>
</html>Hope it helps.

First, 2 elements have the same
id's value :<div id="${id}">and<input id="${id}">You can change same as :
const formulario=document.getElementById("new-task-form");
const lista=document.getElementById("list");
const input=document.querySelector("#new-task-input");
let id=0;
formulario.addEventListener('submit', (e)=>{
//console.log("activado");
e.preventDefault();
addTask();
});
let addTask=()=>{
id ;
let task=input.value;
lista.innerHTML =`<div id="tasks">
<div id="taskin">
<div id="${id}">
<input
id="input-${id}"
type="text"
value=${task}
readonly
/>
</div>
<div >
<button data-task_id="input-${id}">Edit</button>
<button data-task_id="input-${id}">Delete</button>
</div>
</div>
</div> `
input.value='';
}
lista.addEventListener('click', (evento)=>{
if(evento.target.className=="edit"){
document.getElementById(evento.target.dataset.task_id).removeAttribute('readonly');
}else if(evento.target.className=="delete"){
document.getElementById(evento.target.dataset.task_id).remove();
}
})<body>

Maybe you mean remove the readonly attribute on textbox inside the three divs?
$('.edit').click(function(){
$('.first_div input, .second_div input, .third_div input').removeAttr('readonly');
});
$('.edit_first').click(function(){
$('#first_textbox').removeAttr('readonly');
});
$('.edit_second').click(function(){
$('#second_textbox').removeAttr('readonly');
});
$('.edit_third').click(function(){
$('#third_textbox').removeAttr('readonly');
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div >
<input readonly id="first_textbox">
</div>
<div >
<input readonly id="second_textbox">
</div>
<div >
<input readonly id="third_textbox">
</div>
<button >Edit All</button>
<button >Edit first textbox</button>
<button >Edit second textbox</button>
<button >Edit third textbox</button>
