How to Display the Right Movie Information in a JavaScript Overlay?

In web development, displaying the correct information is crucial, especially when creating interactive elements like popups. Suppose you're building a movie gallery application where clicking on a movie should show detailed information in an overlay. You might encounter an issue: no matter which movie you click, the overlay displays the information for only the last movie.

This guide will guide you through understanding this problem and provide a solution to ensure that each movie displays its relevant information correctly in your popup overlay.

Understanding the Problem

When you implement the functionality to show movie details, it’s common to utilize event listeners for elements like buttons. The problem arises from the way you're handling the dynamic elements in your code. Specifically:

You're fetching all elements with the class .seemore and attaching event listeners to them inside a loop.

When a movie is clicked, the event handler refers to the last movie in the loop, leading to all popups displaying the same movie information.

Breaking Down the Solution

Step-by-Step Fix

Separate Event Listener Setup: Instead of assigning event listeners within the movie mapping loop, you must first create all the .seemore elements and then assign the event listeners afterward.

Use the Index: Use the index of the current movie to get the relevant movie information when a .seemore element is clicked.

Updated Code Example

To address the issue, here’s the revised version of your movieIntegration function:

Key Changes in the Code

Movie Mapping: The .seemore elements are created after all movies are rendered in the movieGallery.

Event Listener Uses Index: The index i from the loop of the forEach allows you to access the respective movie's properties when the button is clicked. This ensures that the correct details are shown in the popup.

Conclusion

By restructuring your code to separate concerns and utilize the loop index effectively, you've now enabled your application to display the right movie information in your overlay. This not only improves user experience but also enhances the functionality of your web application.
