Dynamically Adding value Attributes to <option> Elements in jQuery

When working with HTML forms, dropdown selections are a common element that often require additional attributes for effective data handling. One common problem developers face is how to automatically assign value attributes to each <option> based on its displayed text. In this guide, we will walk through a straightforward solution using jQuery.

Here, each option lacks a value attribute. However, it is essential to provide these attributes (e.g., "0930", "1000", "1130") for server-side processing or other manipulations. This leads us to the question: How can we add value attributes to these options dynamically using jQuery?
