the response from the server PHP page:

return json_encode(array('item1'=>'value1', 'item2'=>'value2'));

parse FileUploadResult in javascript:

try {
    var obj = JSON.parse(FileUploadResult.response); // Produces a SyntaxError
} catch (error) {
    console.log(error.message); // Handle the error - Unexpected token
}

try using eval:

eval('var obj=' + FileUploadResult.response);

So in your success function you get an FileUploadResult which you have referred to as "f". Well f has a property called "response" which gives you the response from the PHP page. You'll have to look at the response and use JSON.parse() to turn it into and Object.
