<div>
The general syntax is: $('.selector', 'context'); So, target '.quantity-adder' (the selector) within the closest('.qty') (the context):<br />
$('.quantity-adder', $('button:contains(&quot;Avvisa<wbr />mi quando questo articolo diventa disponibile&quot;)').closest('.<wbr />qty') ) .hide();

Excellent! It works... however since I wasn't expecting the code to be in this format (selector/context), I would like to ask you how I could convert this string in the jquery each format as I have several similar cases on the same page.

Why is this jQuery not working?

jQuery (Core) is a cross-browser JavaScript library that provides abstractions for common client-side tasks such as Document Object Model (DOM) traversal, DOM manipulation, event handling, animation and Ajax. jQuery also provides a platform to create plugins that extend jQuery's capabilities beyond those already provided by the library.

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.

HTML (HyperText Markup Language) is the main markup language for creating web pages and other information to be displayed in a web browser, providing both the structure and content for what is sent from a web server through the use of tags. The current implementation of the HTML specification is HTML5.
