title: What's the best solution to keep hidden ID in a table (HTML)
body: <p>I have a table that shows contacts informations. Each row is a different contact. I'm using JQuery to fire an event when I click some fields of the row. My problem is I need to keep trace of the contact's id but I don't want to show it in a column. So I need each row to be associated to the contact id that it holds without showing it on the screen (like an hidden field).</p>
  
  <p>So what is the best solution to keep trace of that id?</p>
