javascript - Determine and bind click or "touch" event -

I am using the code below to bind "click" or "touchtart" events (using jQuery) .

  what? = (Navigator.userAgent.match (/ ipad / i))? 'TouchStart': 'Click';   
 Later:  
  $ foo.on (what, function () {...});   
 ... which works well for the iPad and "everything", but I'm worried that the code above is "iPad Tunnel Vision" ...  < P>  My question:   
 Did all other devices (for example, Android tablet) have named "TouchStart" event similarly? If so, how can I improve the above code so that I can create an account for those event types?  
 In other words, how would I account for the maximum number of touch devices in the above code (not just the iPad)?  
 
 Edit # 1  
 What people think about it:  
  var foo = ('optarch' in the window) ? 'TouchStart': ((document.DocumentTouch & Document document documentation)? 'Tap': 'click');   
 Note: Most of the above logic are.  
 The above firefox / iPad is working ... I have nothing else to test this time.  
 What do I like about things mentioned above?  
 Is  tap  for all other touch devices a good default?

 There really is no direct answer but many Facing multiple click related events for platforms and devices, gives lots of details.

 Android and iPhone Touch Event  
 WebKit's Android and Touch events in some common in iPhone versions:  
  TouchStart - triggers when triggered mouse equals - mouseDown touchmov - triggers when one touch moves Mouse equivalent - MouseSmouch Touch - Triggers are triggered when the mouse is equivalent - Mouseup is a little special on an iPhone - TouchScan Despicable After reading - Seeing a secret    
, I think I will change the code on it:  
  var foo = (window) 'Achurchch') || (Touch the document document and document presentation presentation))? 'TouchStart': 'Click';   
 When I first asked my question - if I did not have access to anything other than an iPad / iPhone - I took  touchstream  an iOS-specific The event was; It will now see the  touchstart  and  as the basis for the touch code  most if not all, if not all.
