How to Set Multiple Cookies for Multiple Dynamic Divs in JavaScript

When it comes to creating an online cart, one common challenge developers face is managing cookies for multiple dynamic items. Picture this: You want to allow users to add various products (or in our case, cookies) to their cart. However, when you attempt to set a cookie for each product, only the first item's cookie appears to be set. This post tackles the problem and provides a systematic solution to set unique cookies for each dynamic div.

The Problem: Setting Multiple Cookies

Steve, one of our readers, raised a question about setting multiple cookies for dynamic items in a shopping cart. The core problem is that he could only set a single cookie for the first item in his cart, and needed a way to create unique cookies for each product added.

Understanding the Issue

Dynamic Content: The number of products added to the cart is always changing, which complicates cookie management.

Single Cookie Limitation: Only the first item's cookie was being saved, making it impossible to retain information for multiple products.

The Solution: Managing Cookies for Dynamic Divs

To address the issue of dynamic products, we need to set up an efficient way of managing cookies. Below is a step-by-step guide on how to achieve this.

Step 1: Create Cookie Helper Functions

First, let's create helper functions to handle cookie retrieval and parsing. The following JavaScript functions will assist in getting and parsing cookies:

Step 2: Modify the Event Handler

Next, we need to rewrite the click event handler to accommodate multiple cookies. When a user clicks to add a product, we will collect its details and update the cookies accordingly:

Step 3: Ensure Dynamic Functionality

In the modified event handler, we:

Retrieve the current cookie and parse it.

Check if the cookie format is valid and initialize it if necessary.

Create a new order object each time a product is added.

Update the existing cookie with the new order appended.

Conclusion

By following these simple steps, you can create a robust solution for managing cookies for multiple dynamic divs in your shopping cart. Each cookie will uniquely represent an item that has been added, which allows you to maintain the integrity of your shopping experience.

Now, you can seamlessly manage multiple cookies regardless of how many dynamic items are present in the cart! Happy coding!
