在 ASP.NET MVC C# 数据库中首先，我在文本框中对值进行求和，但在数据库中它不会插入 SUM 结果

Question

我想在文本框中找到值的总和，然后在另一个文本框中显示总和，并将总和存储在数据库中。使用下面的代码成功找到总和并将其显示在另一个文本框中但是它不会将总和存储在数据库中。

我检查了数据库，它显示在数据库的 TotalAvgHours 字段中输入了值 NULL。

[HttpPost]
            [ValidateAntiForgeryToken]
            public ActionResult Create(TimePeriodViewModel timePeriodVM)
            {
                var timeperiod = new TimePeriod
                {
                 
                    TotalAvgHours = timePeriodVM.TimePeriod.TotalAvgHours,
                    
    }

                if (!isNaN(result)) {
                    document.getElementById('res2').value = result;
                }
            }

由于在文本框上应用了禁用属性属性，因此您无法在 post 上获取它的数据，而是在文本框上使用只读属性属性。

尝试：

 @Html.TextBox("TotalAvgHours", "", "{0:c}", new { @readonly = "readonly", @class = "form-control", id = "res2" })
