How To Bind Dropdown Using Jquery

When developing a web application, there are often various elements that need to be populated with data. One common element is a dropdown list. In this blog post, we will discuss how to bind a dropdown list using jQuery, a popular JavaScript library for DOM manipulation.


To follow along, you will need the following:

  • A basic understanding of HTML and JavaScript
  • jQuery library (you can either download it or use a CDN)

Getting Started

First, let’s create a simple HTML page with a dropdown list:


        <meta charset="UTF-8">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <title>Dropdown Binding Example</title>
        <script src=""></script>
        <select id="exampleDropdown"></select>

        <script src="script.js"></script>

Next, let’s create a JavaScript file named script.js.

Binding the Dropdown

Now that we have our HTML page and a dropdown list, let’s bind some data to it using jQuery. In this example, we will use an array of objects as our data source:

    $(document).ready(function() {
        // Sample data array
        var data = [
            { id: 1, text: 'Option 1' },
            { id: 2, text: 'Option 2' },
            { id: 3, text: 'Option 3' },

        // Bind the data to the dropdown
        for (var i = 0; i &lt; data.length; i++) {
            $('#exampleDropdown').append($('<option>', {
                value: data[i].id,
                text: data[i].text,

Let’s break down the code:

  1. We use the $(document).ready() function to ensure that the script only runs once the DOM is fully loaded.
  2. We create a sample data array containing objects, each with an id and a text property.
  3. We loop through the data array, and for each object, we use the append() method to add a new <option> element to the dropdown list. The value attribute is set to the object’s id property, and the displayed text is set to the object’s text property.


In this blog post, we covered how to bind a dropdown list using jQuery. This is a useful technique for populating select elements with dynamic data from various sources, such as an API or database. Remember to include the jQuery library in your project and use the append() method to add new <option> elements to your dropdown list.
