title: How do I capture when a finger touches the screen and when a finger is removed from a screen on touchscreen device
body: <p>I am developing an app for a touchscreen and I would like to capture the equivalent of the mouse down and mouse up events. </p>
  
  <p>For example, when the user has their finger touching the screen, a javascript function will execute, but when the finger leaves the screen function stops.</p>
  
  <p>I am using firefox 3.5, with the jQuery framework for my javascript.</p>
  
  <p>Thanks for any help,
  Ben</p>
