touch anywhere on screen to jump

Hey guys I need help to make a character sprite jump when there is a touch detected anywhere on screen. So can you please tell me the code that registers the touch on screen…

Thanks in Advance

this code do not work?

void Update()
  if (Input.GetMouseButtonDown(0))
     //Touch anywhere

From the script reference this is how to detect touches.

function Update () {
  var fingerCount = 0;
  for (var touch : Touch in Input.touches) {
  if (touch.phase != TouchPhase.Ended && touch.phase != TouchPhase.Canceled)
  if (fingerCount > 0)
    print ("User has " + fingerCount + " finger(s) touching the screen");
