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

You can install modernizer and use a simple touch event. This is very effective and works on every device I have tested it on including windows surface!

I've created a jsFiddle

function isTouchDevice(){
    if(Modernizr.hasEvent('touchstart') || navigator.userAgent.search(/Touch/i) != -1){
         alert("is touch");
            return true;
         }else{
            alert("is not touch");
            return false;
    }
}
