Question

I’ve build an Android app in Phonegap and jQuery Mobile and now I want to optimize it, so it will run smoother. I have few performance questions:

1. What is best use of click event handling (for perforamance)

   $('#someID').on('click', function());
   $('#someID').click(function());
   $('#someID').on('vclick', function());
   

2. Is there binded pageshow event, so I wouldn’t have to do it with live?

   $('#somePageId').pageshow(function()) 
   

   instead of

   $('#somePageId').on('pageshow', function())
   

3. Any other tips for better performance will be very helpful. Thank you very much.

1. Delegation -> $(document).on(‘click’,’#someID’, function(e){…});
