Question

我是asp.net的新手;我尝试将RequiredFieldValidator添加到电话号码部分，但我不能在视觉工作室2010，因为它没有＆＃34; id＆＃34;当我在课堂上添加id时，它仍然没有显示。

另外如何在提交按钮上添加onclick？

只显示一个带有RequiredFieldValidator的字段。

Answer 2

您需要使用asp.net服务器端控件，它在运行时创建html。

例如，您可以使用：

<asp:textbox ID='phonenumber' runat='server'/>
<asp:RequiredFieldValidator ID="ValidateName"
     ControlToValidate="phonenumber"                        
     runat="server" ErrorMessage="Phone Number is required is Required"
     Display=Dynamic>
</asp:RequiredFieldValidator>

Asp.net验证与div
