[jQuery] getJSon loop through variable

[Charlie]

Following getJSON works fine but I need to replace "presentations with a variable "getSlides" tried a lot of different ways with a variety of errors no matter what I've treid var getSlides = $(this).attr("href"); $.getJSON("photoList.js",  function(slides){                   $.each(slides.presentations, function(i,item){             $("<img/>").attr("src", item.photo).appendTo("#slideshow");                        });           ///do something             });
