This JavaScript code, executed when the document is fully loaded, performs the following operations:

1. Waits for the Document to Load: The script uses jQuery(document).ready() to ensure that the code inside runs only after the HTML document has been completely loaded and is ready for manipulation.

2. Checks a Specific Element's Value: It accesses a DOM element with the id of "renewbuttonaccess" using JavaScript's document.getElementById() method. Then, it checks the value property of this element to see if it is equal to the string "showbutton".

3. Changes CSS Class if the Condition is Met: If the value of the "renewbuttonaccess" element is "showbutton", the script uses jQuery to find all elements with the class "RenewNowButton". It then removes the hidden class from those elements by calling .removeClass("hidden").

Purpose:

This code appears to conditionally display elements (likely buttons) with the class "RenewNowButton". If the element with the id "renewbuttonaccess" has a value of "showbutton", those buttons will become visible, assuming the hidden class is used to initially hide those elements (e.g., via CSS).
