            });
        });
    }

</script>

and this is my html

   <div id="makeMeScrollable" style="height: 400px; width: 400px;">

</div>

i should append all the images only to the above div replacing the previous images

Answer 1

Try this,

$("#makeMeScrollable").html('ProdcutID<span>' + ele.ProductID +
  '</span>ProductName<span>' + ele.ProductName + '</span>Price<span>' + 
  ele.Price + '</span><img src="' + ele.ImageURL + '" />'); 

You can always use html() in place of append() to remove the existing content.

or you can do empty the element before append with .empty().append()

EDIT (after comments)

 var $div = $("#makeMeScrollable");
    $div.empty();
    $.each(data, function (idx, ele) {.append('ProdcutID' + '<span>' + ele.ProductID + '</span>ProductName<span>' + ele.ProductName + '</span>Price<span>' + ele.Price + '</span>');
        $("<img/>").attr({
            src: ele.ImageURL
        }).appendTo("#makeMeScrollable");
    });
