How to Apply jQuery Functions to Multiple Elements with the Same ID?

Applying jQuery Functions to Elements with the Same ID

jQuery's ability to manipulate elements is crucial for enhancing the functionality of web pages. However, novice jQuery users may encounter difficulties when attempting to apply functions to multiple elements sharing the same ID.

In HTML, IDs serve as unique identifiers for elements. Identifying multiple elements with the same ID is incorrect HTML practice. To distribute functionality across elements, utilize a shared class instead.

However, if altering IDs is impractical, consider the following workarounds:

Using the Same ID (If Unavoidable)

To select elements with the same ID attribute, use the following syntax:

jQuery('[id=carousel]').jcarousel();

Note that this approach is not ideal since IDs should be unique.

Using a Common Class (Recommended Approach)

Assign a common class to the elements you wish to manipulate, then apply the jQuery function using the class selector:

jQuery('.carousel').jcarousel();

This method is more efficient and aligns with HTML best practices. By assigning a common class, you can easily target multiple elements for the same functionality without relying on unique IDs.
