How to Properly Use jQuery to Insert HTML After Specific Classes

In web development, dynamic interactions with HTML elements are often required. One such interaction involves deciding where to insert HTML based on specific conditions. In this guide, we'll explore a common challenge: inserting HTML after certain elements based on their classes while avoiding others.

The Challenge

Suppose you have a set of HTML div elements structured categorically with specific class names:

Problem Statement

When you click on a div with the class A1_B1, the goal is to insert a new <div> with the class class2 immediately after it, but only if the next element does not have the class class1. Additionally, the new HTML should not be inserted following the specific div that was clicked.

Desired Outcome

The expected output after clicking on the A1_B1 div should look something like this:

The Solution

You can achieve the intended functionality using jQuery effectively. Below is the solution that corrects the original attempt.

Step-by-Step Breakdown

Attach a Click Event: Bind an event handler to the class connect, which is located within the A1_B1 divs.

Referencing the Parent Elements: Identify the closest .group container to scope the search for the .A1_B1 divs.

Iterate Over Relevant Divs: Loop through the .A1_B1 divs excluding the one that was clicked.

Check for the Next Class: Within the loop, check if the following sibling div does not have the class class1.

Insert the HTML: If the conditions are satisfied, insert the new HTML right after the targeted div.
