If you're using jQuery, then the result of the AJAX request will be passed back to the Done event as a parameter, That result will be an Object with properties named according to your code (Message in your example above):

$.ajax({
    // your AJAX Options
    dataType: "json",
    url : "somePage",
    method: "post",
    ...
}).done(function(data) {
    // data will be Object, with properties:
    console.log( data.Message );
});

Open in new window

If you're not using jQuery, the principles will likely be the same - your AJAX request will have an event handler that gets ran when it completes. The result of your code will be passed back to that handler as JSON, so you just access the properties accordingly.

file.xhr.responseText = return: {"Message":"3d8d8436-04e3-4866-aca7-0c9f74ae3012.jpg"} look good
but file.Message = return Undefined.

<script>
                            Dropzone.options.myAwesomeDropzone = {
                                init:
                                    function () {
                                    this.on("complete", function (file) {
                                        alert("Save File:  " + file.xhr.responseText);
                                        alert("Json Return Msg: " + file.Message);
                                        document.getElementById("photolistingtodatabase").value = document.getElementById("photolistingtodatabase").value + file.xhr.responseText + ",";
                                    });
                                }
                            };
                        </script>
