javascript - 防止 ASP.Net JSON 删除小数属性中的尾随 0

Question

我正在使用内置的 ASP.Net return JSON() 函数将 View 模型转换为 JSON，在此 View 模型中，属性之一是 decimal 。当此属性填充诸如 4.50 或 4.00 之类的值时，我注意到 View 模型的 JSON 版本正在删除尾随 0。如何停止这种行为，以便当我在 View 中读取 JavaScript 中的数据时得到所有 0？

View 模型:

public class TimeCardEntryVM
{
    public int ID { get; set; }
    public string ProjectCode { get; set; }
    public string ProjectDescription { get; set; }
    public string TaskCode { get; set; }
    public string TaskDescription { get; set; }
    public bool IsDurationTime { get; set; }
    public decimal HoursWorked { get; set; }
    public DateTime StartTime { get; set; }
    public DateTime EndTime { get; set; }
    public string WorkDescription { get; set; }
}

返回 JSON 的 ASP.Net 代码:

{
    var timeEntryData = db.TimeCards
                            .Include(timeCard => timeCard.Project)
                            .Include(timeCard => timeCard.Task)
                            .Where(timeCard => timeCard.ID == timeCardID)
                            .Select(timeCard => new TimeCardEntryVM()
                            {
                                ID = timeCard.ID,
                                EndTime = timeCard.EndDateTime,
                                ProjectCode = timeCard.Project.Code,
                                ProjectDescription = timeCard.Project.Description,
                                StartTime = timeCard.StartDateTime,
                                TaskCode = timeCard.Task.Code,
                                TaskDescription = timeCard.Task.Description,
                                HoursWorked = (decimal)timeCard.TimeWorked,
                                IsDurationTime = timeCard.IsDurationTime,
                                WorkDescription = timeCard.WorkDescription
                            }).First();

    return Json(timeEntryData, JsonRequestBehavior.AllowGet);
}

我用来检查值的 JavaScript 代码:

$.ajax({
    type: "POST",
    url: "/TimeCard/TimeCardEntry",
    data: { timeCardID: args.row["uid"] },
    success: function (data)
    {
        alert(data["HoursWorked"]);
    }
});

为什么不直接使用 .toFixed() 在 JavaScript 中格式化结果:

$.ajax({
    type: "POST",
    url: "/TimeCard/TimeCardEntry",
    data: { timeCardID: args.row["uid"] },
    success: function (data)
    {
        var formattedHours = data.HoursWorked.toFixed(2);
    }
});
