Razor mvc5 c# web用于输入滑块范围
本文关键字:范围 输入 用于 mvc5 web Razor | 更新日期: 2023-09-27 18:16:04
我试图在我的c# mvc 5视图页面上获得一个范围滑块输入,我可以将输入提交给mvc控制器以写入数据库。我尝试使用Jquery Ui滑块,但我无法弄清楚如何将值转换为我的c#代码,用于编写表单数据到数据库。下面是视图CSHTML文件
@model RateMyCourse.ReviewCourse
@{
ViewBag.Title = "Create";
}
<h2>Create</h2>
@using (Html.BeginForm())

很可能你错过了其中一个:
a)我的元素在视图中是否有相应的名称<input type="number" class="nmbr" name="second"/>
b)我是否在绑定列表中包含了我想要的元素
public ActionResult Create([Bind(Include = "second")] ReviewCourse reviewCourse)
这两个是最可能的原因。如果仍然没有,检查你是否真的发布了所有的数据。
