failed send response ajax to html

My HTML Code is like this :

<div class="loading"></div>  

My Javascript Code is like this :

...
                success: function (response) {
                   for(i=0; i<response.SearchAvailResponse.Hotel.length; i++){

                           // console.log(response.SearchAvailResponse.Hotel[i].HotelNo);
                           $parent.find('.loading').html(response.SearchAvailResponse.Hotel[i].HotelNo);

                    }
                }
      ...     

If I run console.log(response.SearchAvailResponse.Hotel[i].HotelNo), the result :

1

2

But when sent to html, the result :

2 

Any solution to solve my problem?

Thank you
