You need a web.config key to enable the pre 4.5 validation mode.
您需要一个 web.config 密钥来启用 pre 4.5 验证模式。
More Info on ValidationSettings:UnobtrusiveValidationMode:
有关ValidationSettings:UnobtrusiveValidationMode 的更多信息：
Specifies how ASP.NET globally enables the built-in validator controls to use unobtrusive JavaScript for client-side validation logic.
Type: UnobtrusiveValidationMode
Default value: None
Remarks: If this key value is set to "None"[default], the ASP.NET application will use the pre-4.5 behavior(JavaScript inline in the pages) for client-side validation logic. If this key value is set to "WebForms", ASP.NET uses HTML5 data-attributes and late bound JavaScript from an added script referencefor client-side validation logic.
Example:
<appSettings> <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" /> </appSettings>
指定 ASP.NET 如何全局启用内置验证器控件以将不显眼的 JavaScript 用于客户端验证逻辑。
类型：UnobtrusiveValidationMode
默认值：无
备注：如果此键值设置为“无”[默认]，则 ASP.NET 应用程序将使用4.5 之前的行为（页面中的 JavaScript 内联）进行客户端验证逻辑。如果此键值设置为"WebForms"，则 ASP.NET 使用HTML5 数据属性和来自客户端验证逻辑的添加脚本引用的后期绑定 JavaScript。
例子：
<appSettings> <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" /> </appSettings>

Rather than disabling a new feature, I opted to follow the instructions of the error. In my global.asax.cs I added:
我没有禁用新功能，而是选择按照错误说明进行操作。在我的 global.asax.cs 中，我添加了：
protected void Application_Start(object sender, EventArgs e)
{
string JQueryVer = "1.7.1";
ScriptManager.ScriptResourceMapping.AddDefinition("jquery", new ScriptResourceDefinition
{
Path = "~/Scripts/jquery-" + JQueryVer + ".min.js",
DebugPath = "~/Scripts/jquery-" + JQueryVer + ".js",
CdnPath = "http://ajax.aspnetcdn.com/ajax/jQuery/jquery-" + JQueryVer + ".min.js",
CdnDebugPath = "http://ajax.aspnetcdn.com/ajax/jQuery/jquery-" + JQueryVer + ".js",
CdnSupportsSecureConnection = true,
LoadSuccessExpression = "window.jQuery"
});
}
This comes from an msdn blog postwhich highlights some of the advantages of script resource mappings. Of particular interest to me was centralized control over the delivery of the script files based on "debug=true", EnableCDN, etc.
这来自msdn 博客文章，该文章强调了脚本资源映射的一些优点。我特别感兴趣的是基于“debug=true”、EnableCDN 等对脚本文件的交付进行集中控制。

There are at least three ways to disable the use of unobtrusive JavaScript for client-side validation:
至少有三种方法可以禁用不显眼的 JavaScript 进行客户端验证：
- Add the following to the web.config file:
<configuration> <appSettings> <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" /> </appSettings> </configuration> - Set the value of the
System.Web.UI.ValidationSettings.UnobtrusiveValidationModestatic property toSystem.Web.UI.UnobtrusiveValidationMode.None - Set the value of the
System.Web.UI.Page.UnobtrusiveValidationModeinstance property toSystem.Web.UI.UnobtrusiveValidationMode.None
- 将以下内容添加到 web.config 文件中：
<configuration> <appSettings> <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" /> </appSettings> </configuration> - 将
System.Web.UI.ValidationSettings.UnobtrusiveValidationMode静态属性的值设置为System.Web.UI.UnobtrusiveValidationMode.None - 将
System.Web.UI.Page.UnobtrusiveValidationMode实例属性的值设置为System.Web.UI.UnobtrusiveValidationMode.None
To disable the functionality on a per page basis, I prefer to set the Page.UnobtrusiveValidationModeproperty using the page directive:
要在每页的基础上禁用该功能，我更喜欢Page.UnobtrusiveValidationMode使用 page 指令设置属性：
<%@ Page Language="C#" UnobtrusiveValidationMode="None" %>

Unobtrusive validation is enabled by default in new version of ASP.NET. Unobtrusive validation aims to decrease the page size by replacing the inline JavaScript for performing validation with a small JavaScript library that uses jQuery.
新版本的 ASP.NET 中默认启用不显眼的验证。非侵入式验证旨在通过使用使用 jQuery 的小型 JavaScript 库替换用于执行验证的内联 JavaScript 来减小页面大小。
You can either disable it by editing web.config to include the following:
您可以通过编辑 web.config 以包含以下内容来禁用它：
<appSettings>
<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
</appSettings>
Or better yet properly configure it by modifying the Application_Start method in global.asax:
或者通过修改 global.asax 中的 Application_Start 方法更好地正确配置它：
void Application_Start(object sender, EventArgs e)
{
RouteConfig.RegisterRoutes(System.Web.Routing.RouteTable.Routes);
ScriptManager.ScriptResourceMapping.AddDefinition("jquery",
new ScriptResourceDefinition
{
Path = "/~Scripts/jquery-2.1.1.min.js"
}
);
}
Page 399 of Beginning ASP.NET 4.5.1 in C# and VB provides a discussion on the benefit of unobtrusive validation and a walkthrough for configuring it.
在 C# 和 VB 中开始 ASP.NET 4.5.1 的第 399 页讨论了不显眼的验证的好处以及配置它的演练。
For those looking for RouteConfig. It is added automatically when you make a new project in visual studio to the App_Code folder. The contents look something like this:
对于那些寻找 RouteConfig 的人。当您在 Visual Studio 中创建新项目时，它会自动添加到 App_Code 文件夹中。内容如下所示：

using Microsoft.AspNet.FriendlyUrls;
namespace @default
{
public static class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
var settings = new FriendlyUrlSettings();
settings.AutoRedirectMode = RedirectMode.Permanent;
routes.EnableFriendlyUrls(settings);
}

Solves the issue, but then it makes your validation controls/scripts throw Javascript runtime errors.If you change to:
解决了这个问题，但随后它会使您的验证控件/脚本抛出 Javascript 运行时错误。如果您更改为：

You should be OK, but you'll have to make sure the rest of your code does/ behaves as desired. You might also have to forgo some new features only available in 4.5 onward.
你应该没问题，但你必须确保你的代码的其余部分按预期做/表现。您可能还必须放弃一些仅在 4.5 及更高版本中可用的新功能。

它有其他人告诉上层的 3 个解决方案......但是当尝试 Application_Start 解决方案时，我的其他 jQuery 库（如 Pickup_Date_and_Time）不起作用......所以我测试了第二种方式并得到了回答：1-将目标框架设置为 Pre 4.5 2 - 在页眉中使用“ UnobtrusiveValidationMode="None" " =>
<%@ Page Title="" Language="C#"
MasterPageFile="~/Master/MasteOfHotel.Master"
UnobtrusiveValidationMode="None" %>
it works for me and doesn't disrupt my other jQuery function.
