防止ASP.Net JSON从在十进制属性中删除尾随0

本文关键字：删除 属性 十进制 Net ASP JSON 防止 | 更新日期: 2023-09-27 18:12:07

我正在使用内置的ASP。Net return JSON()函数将视图模型转换为JSON，在此视图模型中，其中一个属性是decimal。当这个属性被像4.50或4.00这样的值填充时，我注意到视图模型的JSON版本正在删除末尾的0(s)。我如何阻止这种行为，所以当我在视图中读取JavaScript中的数据时，我得到所有的0 ?

ViewModel: 

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; }
}

ASP。. Net代码返回JSON:

{
    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"]);
    }
});

防止ASP.Net JSON从在十进制属性中删除尾随0

为什么不直接在JavaScript中使用.toFixed():

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