function ajaxJson(method, url, data, callback) {
    var options = {
        type: method,
        url: url,
        dataType: 'JSON',
        traditional: true,
        contentType: "application/json; charset=utf-8"
    };
    if (typeof data === 'function') { // No data offered
        callback = data;
    } else { // Add data
        options.data = data;
    }
    options.success = function (msg) {
        return callback(null, msg);
    };
    options.error = function (err) {
        return callback(err);
    };
    $.ajax(options);
}
