Please help me for this.

Going to need to see more code, how are you calling the ajax add to cart?

Line 138 in public.common.js is:

var content = document.createElement('p');

So if you're seeing "Cannot read property 'dataset' of null" it means the DOM isn't loaded (document is null).

Line 98 in public.ajaxcart.js is just after:

                    //specify timeout for success messages
                    displayBarNotification(response.message, 'success', 3500);

So if I had to guess your add to cart is actually timing out.  You'll need to set break points to step through and see what's happening.
