title: Getting a href from a button
body: <p>I'm trying to extract the href from certain buttons from <a href="https://www.iefp.pt/ofertas-emprego" rel="nofollow noreferrer">this url</a> (the buttons are located bellow the h4 "Ofertas Disponíveis".
  <a href="https://i.stack.imgur.com/71kui.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/71kui.png" alt="enter image description here"></a></p>
  
  <p>These buttons have an onclick function called "updateJobModal(button_index)" but I can't locate the function.
  At the end of the tag, an "ev" button appears to be related to JQuery.</p>
  
  <p>How can I obtain the attribute in this case?</p>
