            }else if (chrome.notifications) {var opt = {type: ' Basic ', title: ' Notice of title! ', 
            Message:data, Iconurl: ' Images/icon.png ',} chrome.notifications.create (', OPT, function (ID) {
       	    settimeout (function () {Chrome.notifications.clear (ID, function () {});
      	}, 3000);
    
    }); }else{alert (' Pro, your browser doesn't support AH.
    '); }
