if (data.ReplaceDataFields != null) {

$.each(data.ReplaceDataFields, function (i, item) {
                            $("<option></option>")
                            .val(item.ItemKey)
                            .text(item.ItemValue + "(" + item.ItemKey + ")")
                            .attr("Id", item.ItemKey)
                            .appendTo($("#selDataFields"));
                        });
                    }

效果如下:

<option value="hotelName" id="hotelName">酒店名称(hotelName)</option>

<option value="rooms" id="rooms">预订数量(rooms)</option>
