Extend the previous problem to display a [Delete] link after each list item. Clicking it, should delete the item with no confirmation.
Input/Output:
There will be no input/output, your program should instead modify the DOM of the given HTML document.
Sample HTML:
<h1>List of Items</h1>
<ul id="items"></ul>
<input type="text" id="newText" />
<input type="button" value="Add"
onclick="addItem()">
<script>
function addItem() { ...
function deleteItem() { ... }
}
</script>

Here is my solution:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
<h1>List of Items:</h1>
<ul id="items"></ul>
<input type="text" id="newText">
<input type="button" value="Add New Text" onclick="addItem()">
<script>
function addItem() {
let input = document.getElementById("newText");
let text = input.value;
let newLi = document.createElement("li");
newLi.textContent = text + " ";
let deleteLink = document.createElement("a");
deleteLink.textContent = "[Delete]";
deleteLink.href = "#";
deleteLink.addEventListener("click", deleteItem);
newLi.appendChild(deleteLink);
document.getElementById("items").appendChild(newLi);
input.value = "";
function deleteItem() {
document.getElementById("items").removeChild(newLi);
}
}
</script>
</body>
</html>
Another function:
function addItem() {
let text = document.getElementById("newText").value;
let li = document.createElement("li");
li.textContent = text;
let span = document.createElement("span");
span.innerHTML = " <a href = '#'>[Delete]</a>";
span.addEventListener("click", function () {
let li = span.parentNode;
li.parentNode.removeChild(li);
});
li.appendChild(span);
let items = document.getElementById("items");
items.appendChild(li);
document.getElementById("newText").value = "";
}
