How to Dynamically Display Selected Item Images in Laravel and jQuery

Creating an interactive web application often involves manipulating the Document Object Model (DOM) to display dynamic content based on user input. In this post, we will tackle a common problem faced by developers: dynamically displaying images of selected items using Laravel and jQuery.

The Problem

In web applications, you may have forms with dynamically added rows, each containing a dropdown (select box) for various selections. When a user selects an item from this dropdown, you might want to display additional information, such as an image associated with the selected item.

In our case, we faced two issues:

Multiple images were being displayed for each row when selecting an item from the dropdown.

The correct image for the selected item was not being shown.

Let’s dive into the solution that will address both of these issues.

The Solution

Here's a step-by-step breakdown of how to implement a solution using Laravel and jQuery.

1. HTML Structure

First, we need to ensure that the HTML structure is set up correctly to support dynamic elements. Here's a simplified version of our setup:

4. Improve the Deletion Functionality

To innovate our solution, we should ensure that when a user deletes a row, it also removes the corresponding HTML block:

Summary

In this guide, we tackled the issue of dynamically displaying images based on user selection in a dropdown using Laravel and jQuery. By properly handling dynamic additions and ensuring that images are correctly associated with their respective rows, you can create a more intuitive user experience on your web application.

Feel free to experiment with the code and integrate it into your projects. Happy coding!
