one of my classes in Javascript needs to be updated with Json sometimes. I have always done a function, that updates the array of data, given an id, but now i wanted to do it more encapsulated (Function update, inside the class).

What i made:

function File(data){

        this.data = data;



        this.update = function (callback){

            var set = function(ajaxData){

                this.data = ajaxData.PcbFile;

            }

            getPcbFile(data.id, function(ajaxData){

                set(ajaxData);

                callback();

            });

        };

    }

But, this.data = ajaxData.PcbFile; doesen't work... My object still with the last data set, and not the updated one. The function SET, i created as another attempt to set the data.

There is no problem on the ajax, since i debuged the ajaxData, and it's ok (when i update).

So, how do i really access the object property data from an inside function?

(sorry for my english...)
