c# - get input type="number" tag to run on server

Question

I have two html5 input number controls on my page and I would like to use their value through code behind. but when I add the runat="server" attribute I still cannot catch them in the cs file. is there a way to do it?

here are my controls:

<input id="hour_input" type="number" min="1" max="12" step="1" value ="1" runat="server"/>
            <input id="minutes_input" type="number" min="0" max="60" step="5" value ="0" runat="server"/>

it gives: "the name 'hour_input' does not exist in the current context"

Answer 1

Microsoft 发布了 .NET Framework 4 的更新，允许 TextBox 支持 HTML 5 属性。

在您的页面加载中，您可以简单地添加以下内容：

 hour_input.Attributes.Add("type", "number");
