Finding a div Class Name from AJAX Content in jQuery

When working with AJAX responses in jQuery, you might encounter a situation where you need to extract specific class names from the returned HTML content. In this guide, we focus on a common problem: how to find a div class name that contains a certain keyword (in this case, item-title), regardless of the number or other characters present in the class name.

Understanding the Problem

Imagine you receive an AJAX response like this:

Your goal is to extract item-title3 from this content. The complexity arises because you might not know the exact structure or variations of the class names ahead of time; you only want to target those that contain the substring item-title.

The Solution: Step-by-Step Guide

We will break down the solution into clear sections to make it easy to follow.

Step 1: Using jQuery to Select the Class

To start, you can use jQuery's powerful selection capabilities to grab any div elements with class names that contain item-title. Here's how you can do it:
