How to Retrieve the Value of <ion-select> Without jQuery

In the world of web development, select elements are essential for gathering user input. However, when working with frameworks like Ionic, it can be tricky to extract values, especially if we want to avoid using libraries such as jQuery.

If you've been struggling to get the value of an <ion-select> element using pure JavaScript, this post is for you! We'll go through the entire process step-by-step, ensuring clarity and ease of understanding.

The Problem

Suppose you have a user form created with Ionic that allows users to select their country. When the user selects a country and clicks a button, you want to display the chosen option in an alert box. The challenge is to achieve this without relying on jQuery or other libraries, using only Vanilla JavaScript.

Initial Code Structure

Here is what the basic structure of your HTML and JavaScript might look like:

The Problem in the Code

The issue with the above code is that the selected value will not be accessible until an option is selected. Here's how to improve the code:

The Solution

Step 1: Update Your HTML

First, we need to ensure that the <ion-select> is visible to the user. We will remove the style="display: none;" attributes:

Step 2: Modify the JavaScript Function

Now, we need to modify the JavaScript function to ensure we can retrieve the selected option when the button is clicked:

How It Works

Event Listener: We add an event listener to the <ion-select> element that detects when the value changes. This way, we can respond to user selections in real-time.

Display Selected Value: When the button is clicked, the myFunction() retrieves the value of the selected country and shows it in an alert box.

Summary

To summarize the steps to retrieve the value of an <ion-select> without using jQuery:

Ensure the <ion-select> is visible in your HTML.

Use Vanilla JavaScript to directly access the selected value.

Add an event listener to handle changes effectively.

By following these steps, you can easily get the value of an <ion-select> element in Ionic using only Vanilla JavaScript, creating a smoother user experience.

Happy coding, and enjoy building your Ionic forms efficiently without extra libraries!
