title: How to attach preventDefault() and function to physical back button on mobile?
body: <p>I would like to display a slide-down menu (containing all links) when the back button is pressed. There are only 5 pages and each page is a div called by javascript which makes the back button useless without the requested modification.</p>
  
  <p>How do I call my custom functions from the back button using jQuery?</p>
  
  <p>Thanks a lot ! :)</p>
