Can you please explain to me how to target a specific element by its ID in the DOM and then move on to the next element with the same ID using jQuery

During the event handling process, a scenario arises where two div elements end up having identical IDs within the DOM structure.

While using JQuery, my objective is to specifically target the second occurrence of the div with the aforementioned ID in the document.

I am in search of a precise method that allows me to achieve this, like using $('#theMentionedId').nextWithTheSameId()...

Initially, I focus on selecting the element with the mentioned ID $('theID');

Now the question remains: how do I navigate to the next element with the same ID within the DOM?

Although there are various techniques and solutions available for this issue, I prefer to implement the approach I have outlined above.

It's recommended to use classes instead of non-unique unique ids. Unique ids should only be used once, while classes can be reused multiple times.

The id attribute provides a unique identifier for an element. The value must be distinct among all IDs in the element's subtree

If you are unable to modify the existing code and need to select the second element with the same id, jQuery's attribute equals selector can be utilized. It follows a 0-index style format, so the second element will have an index of one.

$('[id="YourIdHere"]').eq(1); // Select second element matching #YourIdHere
