How to Capture the Current Data Slider in Bootstrap Carousel Changes?

If you're working on a web project that uses Bootstrap's carousel component and need to track data from the current slide, you've come to the right place. Specifically, you might be wondering how to retrieve and utilize the data from the slider not just when it changes, but also initially, when the carousel is first loaded. In this guide, we will explore a solution to ensure that you can track your promotional banners effectively and ensure that the first slide's data is captured and sent to Google Analytics.

Problem Overview

You’ve created a slider where each slide has a data-banner attribute that contains essential data for tracking purposes. However, when the page initially loads, the data from the first slide does not seem to be captured in the console. This issue can lead to incomplete data in your analytics logs.

Solution Breakdown

Here’s how you can modify your JavaScript code to ensure that the data from the initial slide is captured and displayed alongside data from subsequent slides when the carousel changes.

Step 1: Initialize the Data Capturing

You want to make sure that your JavaScript listens to the loading of your carousel and retrieves the data immediately from the first slide.

Step 2: Capturing Data When the Carousel Changes

Next, you need to add an event listener for when the carousel slides change. This event will capture the data from the active slide after it changes.

Step 3: Integrating Google Analytics (Optional)

If you also want to send this data to Google Analytics, you should uncomment the gtag call and integrate that function accordingly. It allows you to track how many times each banner is viewed, giving you insight into user interactions with your promotions.
