Understanding the Problem: JavaScript Click Scroll with Multiple Elements

Having multiple interactive elements on a web page often leads to a common challenge: ensuring that actions triggered by one element do not interfere with others. In this instance, you have a JavaScript scrolling script that appears to work well for the first element but fails to respond for any subsequent elements on the page.

This problem can arise due to how events are registered and how elements are targeted in the document. Let's explore how to fix this issue and ensure that all elements respond correctly to user interactions.

Solutions to the Problem

To resolve the issue of making multiple elements scroll in unison upon clicking an icon, we need to adjust how we select and interact with these elements. Here's a step-by-step breakdown of a successful approach:

Step 1: Select All Scrollable Elements

Step 2: Loop Through Each Element

Next, we should iterate through each of these selected elements and apply the scrolling functionality to each one. We can do this with the forEach method.

Step 3: Create a Function for Each Gallery

Inside this loop, we will define a function named gallery, which will handle the scroll behavior for each individual element passed to it.

Key Considerations

Unique Class Names: This solution assumes that no other elements in the DOM share the class name "test-js" because this could cause selector conflicts. Striving for unique identifiers like ids, specific attributes, or combinations of classes is a best practice.

Hierarchy Structure: Ensure that each test-js element is properly structured and contains all necessary child nodes needed for scrolling.

Conclusion

By following these steps and structuring your code effectively, you can ensure that each scrolling element functions independently and cohesively on your webpage. Implementing a looping mechanism for event listeners allows you to harness the power of JavaScript, leading to a more interactive and engaging user experience on your site.

If you encounter more complex issues or have unique setups, consider revisiting your HTML structure or using additional JavaScript tools for more control over DOM elements.
