我的視圖模型中包含以下模型public class FloorPlanSettingsModel{    public int Id { get; set; }    public int? MainFloorPlanId { get; set; }    public string ImageDirectory { get; set; }    public string ThumbnailDirectory { get; set; }    public string IconsDirectory { get; set; }}如何從Javascript訪問上述屬性之一？我嘗試了這個，但是我得到了“未定義”var floorplanSettings = "@Model.FloorPlanSettings";alert(floorplanSettings.IconsDirectory);
