gistfile1.js

try{
  document.createEvent("TouchEvent");

  // Here we're ensured touch capabilities
  var scroll = document.getElementById('myid');
  var start = null;
  var clickIfEnd = true;
  scroll.addEventListener('touchstart', function (e) {
    start = e.touches[0].pageX;
    clickIfEnd = true;
    e.preventDefault();
  }, false);
  scroll.addEventListener('touchmove', function (e) {
    this.scrollLeft = start - e.touches[0].pageX;
    clickIfEnd = false;
    e.preventDefault();
  }, false);
  scroll.addEventListener('touchend', function (e) {
    if (clickIfEnd) {
      if (e) {
        clickIfEnd = e.target;
        // Add a delay before treating this as a click, in case it was accidental
        setTimeout(arguments.callee, 100);
      } else {
        // clickIfEnd is the element that was clicked!
      }
    }
  }, false);
} catch(e){}
