I’m learning vanilla JS and trying to make "To-do list" project.
So, idea is simple adding values from form into the list. After that I add edit/remove buttons for every li in list and put the addEventListener to that buttons.
For some reason, event listener is targeted on button from form. When I click on button to add new item in list, there is click listener that I want on edit button.
I try different ways to target the right button with parentNodes or childNodes, i find the pretty same code as mine but that don’t work for me.
function newItem() {
let input = document.getElementById("input").value;
if (input != "") {
let li = document.createElement("li");
li.appendChild(document.createTextNode(input));
let editButton = document.createElement("button");
editButton.appendChild(document.createTextNode("Edit"));
li.appendChild(editButton);
editButton.addEventListener("click", console.log('a'));
let ul = document.getElementById("list");
ul.appendChild(li);
document.getElementById("input").value = "";
}
function editItem() {
alert('e');
}

<input id = "input" type = "text" placeholder="What do you want to do?" value="">
<button id = "enter" onclick = "newItem()">Ok</button>

<ul id = "list">

>Solution :
You need to pass a function in addEventListener, not just code.
editButton.addEventListener("click", ()=>{console.log('a')});
Or pass it to editItem
editButton.addEventListener("click", editItem);
