推荐答案

您需要一个 web.config 密钥来启用 pre 4.5 验证模式.

You need a web.config key to enable the pre 4.5 validation mode.

关于ValidationSettings:UnobtrusiveValidationMode的更多信息:

More Info on ValidationSettings:UnobtrusiveValidationMode:

指定 ASP.NET 如何全局启用内置验证器控件使用不显眼的 JavaScript 进行客户端验证逻辑.

Specifies how ASP.NET globally enables the built-in validator controls to use unobtrusive JavaScript for client-side validation logic.

类型:UnobtrusiveValidationMode

Type: UnobtrusiveValidationMode

默认值:无

备注:如果此键值设置为"None" [默认]，则 ASP.NET应用程序将使用 4.5 之前的行为(JavaScript inline in页面)用于客户端验证逻辑.如果设置了这个键值对于 WebForms"，ASP.NET 使用 HTML5 数据属性和后期绑定来自添加的脚本参考的 JavaScript 用于客户端验证逻辑.

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 reference for client-side validation logic.

示例:

    <appSettings>
      <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
    </appSettings>
