In web development, manipulating the content displayed on a webpage is an important skill. One way to accomplish this is through the JavaScript createtextnode.
This powerful function allows you to create and insert text nodes within HTML elements, dynamically changing your page’s content.
In this article, we will discuss the details of using CreateTextNode JavaScript with example codes, allowing you to improve user experiences on your website.
Methods to Use in CreateTextNode JavaScript
Here are the following methods to Use in CreateTextNode JavaScript.
Method 1: Using CreateTextNode to Add Text Content
One of the essential use cases of the CreateTextNode function is to dynamically insert text content into HTML elements.
Let’s see the following example code:
const targetElementValue = document.getElementById('target');
const newTextMessage = 'Welcome Itsourcecode!';
const textNodeResult = document.createTextNode(newTextMessage);
targetElementValue.appendChild(textNodeResult);
In this example, we select an HTML element using its ID, create a text node that consists of the desired text, and then append it to the selected element.
This process ensures that the text is added to the webpage dynamically.

Manipulating Text Content
With CreateTextNode, you’re not limited to adding static text. You can also manipulate existing text content constantly.
Let’s say you have a paragraph element and want to change its text content based on user interactions.
Here’s an example code of how you can do it:
const paragraphValue = document.getElementById('paragraph');
function changeTextValue() {
const newTextSample = 'New text content!';
paragraphValue.firstChild.nodeValue = newTextSample;
}
In this example, the changeTextValue function changes the text content of the targeted paragraph element.
By accessing the firstChild of the paragraph and updating its nodeValue, you will accomplish dynamic content manipulation.
Handling User Inputs
User inputs are an integral part of interactive web pages. You can combine user inputs with CreateTextNode to display custom messages or data.
Here’s a simple form input example code:
<input type="text" id="userInput">
<button onclick="displayInputValue()">Display Input</button>
<p id="output"></p>
<script>
function displayInputValue() {
const userInputValue = document.getElementById('userInput').value;
const outputElement = document.getElementById('output');
const textNodeValue = document.createTextNode(`User input: ${userInputValue}`);
outputElement.appendChild(textNodeValue);
}
</script>
In this example code, when the user enters text into the input field and clicks the button, the entered text is displayed below as part of a dynamically created text node.
