How to Generate Barcode Using a String

Barcodes are widely used in various industries for inventory management, product tracking, and many other purposes. In this blog post, we will explore how to generate a barcode using a string of text. We will use HTML, CSS, and JavaScript to accomplish this task.

Setting Up the HTML Structure

First, let’s create the basic HTML structure for our barcode generator. We will use a simple form to input the string for which we want to generate the barcode. We will also include a button to trigger the barcode generation process.

<form id="barcodeForm">
  <label for="inputString">Enter the text:</label>
  <input type="text" id="inputString" name="inputString" required>
  <button type="button" onclick="generateBarcode()">Generate Barcode</button>

Styling the Barcode

Next, let’s add some CSS to style our barcode. We will use a <div> element to display the barcode, and we will apply some CSS properties to make it visually appealing.

  #barcode {
    width: 100%;
    height: 100px;
    background-color: #FFF;
    border: 1px solid #000;
    display: flex;
    justify-content: center;
    align-items: center;
    font-size: 20px;

Generating the Barcode Using JavaScript

Now, let’s write the JavaScript code to generate the barcode based on the input string. We will use a library called “JsBarcode” to generate the barcode. You can download this library from the official website or include it from a CDN.

<script src=""></script>
  function generateBarcode() {
    var inputString = document.getElementById("inputString").value;
    JsBarcode("#barcode", inputString);

Displaying the Barcode and Download Code Button

Finally, let’s add the <div> element to display the generated barcode, and a button to download the code for our readers to use in their own projects.

<div id="barcode"></div>
<button onclick="downloadCode()">Download Code</button>

And that’s it! With this HTML, CSS, and JavaScript code, you can now generate a barcode using a string of text. Users can input any desired string, and the barcode will be generated dynamically.


In this blog post, we have learned how to generate a barcode using a string of text. We used HTML, CSS, and JavaScript to create a simple barcode generator. By following the steps outlined in this post, you can easily implement a barcode generator in your own projects.

Feel free to experiment with different CSS styles and JavaScript libraries to enhance the functionality and appearance of your barcode generator. Happy coding!
