What's the best way to detect a 'touch screen' device using JavaScript?

Question

I\'ve written a jQuery plug-in that\'s for use on both desktop and mobile devices. I wondered if there is a way with JavaScript to detect if the device has touch screen capa

Answer 1

It looks like Chrome 24 now support touch events, probably for Windows 8. So the code posted here no longer works. Instead of trying to detect if touch is supported by the browser, I'm now binding both touch and click events and making sure only one is called:

myCustomBind = function(controlName, callback) {

  $(controlName).bind('touchend click', function(e) {
    e.stopPropagation();
    e.preventDefault();

    callback.call();
  });
};

And then calling it:

myCustomBind('#mnuRealtime', function () { ... });

Hope this helps !
