How to remove an added list items using JavaScript ?

  • Last Updated : 06 Jul, 2021

In the following article,  we dynamically add and remove list items using JavaScript. We are using JavaScript to add and/or remove list items dynamically which means that if we run our webpage it will show the option of adding and removing items using buttons.

 Approach: In the webpage, one input text box is given for the user entry to add a list item. Two buttons are given to add a list item and also remove a list item. The list items are added or removed using JavaScript functions addItem() and removeItem(). The list items are created using document.createElement() method and to create a text node, document.createTextNode()  method is used and then this node is appended using appendChild() method. The list item is deleted using the removeChild() method.

Hey geek! The constant emerging technologies in the world of web development always keeps the excitement for this subject through the roof. But before you tackle the big projects, we suggest you start by learning the basics. Kickstart your web development journey by learning JS concepts with our JavaScript Course. Now at it's lowest price ever!

The in-built functions used are listed below.

  • Create new elements: We can create new elements using the document.createElement() function. It will create elements dynamically.
  • Append element: We can append elements using the function appendchild(). 
  • Create text node: We can create a text node using the document.createTextNode() element.  HTML consists of both an element node and a text node. So createTextNode() method creates a text node with the specified text.
  • Remove existing element: We can remove a child from the created list by using removechild() function.

Example: The following code demonstrates the addition and deletion of list items using JavaScript functions.


<!DOCTYPE html>
<html lang="en">
        #candidate {
            border-radius: 20%;
            border-color: aquamarine;
            box-sizing: border-box;
        .buttonClass {
            border-radius: 20%;
            border-color: aqua;
            border-style: inherit;
        button:hover {
            background-color: green;
    <ul id="list"></ul>
    <input type="text" id="candidate" />
    <button onclick="addItem()" class="buttonClass">
    Add item</button>
    <button onclick="removeItem()" class="buttonClass">
    Remove item</button>
        function addItem() {
            var a = document.getElementById("list");
            var candidate = document.getElementById("candidate");
            var li = document.createElement("li");
            li.setAttribute('id', candidate.value);
        // Creating a function to remove item from list
        function removeItem() {
            // Declaring a variable to get select element
            var a = document.getElementById("list");
            var candidate = document.getElementById("candidate");
            var item = document.getElementById(candidate.value);

Output: Now, click on add item to add any item to the list. Click on remove item to delete any item from the list.
