How to Quickly Extract Selected Option Values and Attributes from HTML <select> Elements Using jQuery

In web development, working with forms and user input is a common task, especially when dealing with dropdown lists represented by <select> elements in HTML. If you've ever found yourself needing to retrieve the selected value from these dropdowns along with a relevant attribute, this guide is for you!

In this post, we’ll discuss how to effectively extract the selected option's value and attribute from a list of <select> elements using jQuery. Let’s dive into the problem and our solution.

The Problem

You may have encountered a situation similar to the following: you have multiple <select> elements (dropdowns) on your webpage, and you want to obtain the value of the option that a user selects. However, in addition to this value, you also need to retrieve a custom attribute (data-id) associated with the selected option.

To illustrate, here is a sample HTML structure of the dropdowns:

When a user changes their selection, you want to retrieve:

The value of the selected option (e.g., id1, id2, etc.)

The data-id attribute of that selected option

The Solution

To solve this problem, you can utilize jQuery's powerful event handling and DOM manipulation capabilities. Here’s a step-by-step breakdown of how you can achieve this:

Step 1: Bind the Change Event

You need to listen for changes to any of the <select> elements using jQuery's on() method.

Step 2: Get the Selected Option

You can retrieve the selected option by using the :selected pseudo-selector.

Step 3: Retrieve the Values

Obtain both the value and the data-id attribute of the selected option using jQuery methods.

Here’s how you can implement the solution in code:
