推荐答案

使用自定义验证器，并让它们全部调用通用JS文件中的函数.

Use custom validators and have them all call a function that''s in a common JS file.

CustomValidator控件为输入控件提供用户定义的验证功能.验证有两种类型
1.服务器端
2.客户端
这是您的问题的解决方案
在网页中插入自定义验证程序控件，然后分配以下属性
< asp:CustomValidator runat = server
controltovalidate ="txtName"
errormessage ="ID无效"
OnServerValidate ="CheckID"/>

在网页的代码后面编写以下代码以进行验证
公共无效CheckID(对象源，ServerValidateEventArgs args)
{
args.IsValid = true;
foreach(args.Value.ToString()中的char chr)
{
if(char.IsDigit(chr)==否&& char.IsLetter(chr)==否)
{
args.IsValid = false;
返回；
}
}
}

The CustomValidator control provides user-defined validation function for an input control. There are two types of validation
1. Server side
2. Client side
Here is the solution for your problem
Insert a custom validator control in the web page and assign the following properties
<asp:CustomValidator runat=server
controltovalidate="txtName"
errormessage="ID is not valid"
OnServerValidate="CheckID" />

Write the following code in code-behind of the web page for validation
public void CheckID(Object source, ServerValidateEventArgs args)
{
args.IsValid = true;
foreach (char chr in args.Value.ToString())
{
if (char.IsDigit(chr) == false && char.IsLetter(chr) == false)
{
args.IsValid = false;
return;
}
}
}
