Asp.net 客户端验证库在哪里？

我正在为sharepoint 2010编写代码。根据这一点，当您查看浏览器的页面源代码时，您应该找到类似这样的内容，以便使用验证库。我没有找到它

<script language="javascript" 
        src="/aspnet_client/system_web/1_0_3617_0/WebUIValidation.js">
</script>

---

我很困惑，您能否解释一下验证库是如何加载到客户端浏览器的。

WebUIValidation.js文件包含用于客户端验证的客户端JavaScript函数。在以下情况下，它会自动注入页面：

• 该页包含一个或多个验证Web控件
• “uplevel”浏览器正在访问该页面

我在

System.Web.UI.WebControls.BaseValidator

类中启动了Reflector，以在该类中sneek一个峰值，该类是所有验证Web控件的派生类。

RegisterValidationCommonScript（）

方法负责

归功于：

通过ILSpy（.NET 4.0）反映：

// System.Web.UI.WebControls.BaseValidator
protected void RegisterValidatorCommonScript()
{
    if (this.Page.IsPartialRenderingSupported)
    {
        ValidatorCompatibilityHelper.RegisterClientScriptResource(this, typeof(BaseValidator), "WebUIValidation.js");
        ValidatorCompatibilityHelper.RegisterStartupScript(this, typeof(BaseValidator), "ValidatorIncludeScript", "\r\nvar Page_ValidationActive = false;\r\nif (typeof(ValidatorOnLoad) == \"function\") {\r\n    ValidatorOnLoad();\r\n}\r\n\r\nfunction ValidatorOnSubmit() {\r\n    if (Page_ValidationActive) {\r\n        return ValidatorCommonOnSubmit();\r\n    }\r\n    else {\r\n        return true;\r\n    }\r\n}\r\n        ", true);
        ValidatorCompatibilityHelper.RegisterOnSubmitStatement(this, typeof(BaseValidator), "ValidatorOnSubmit", "if (typeof(ValidatorOnSubmit) == \"function\" && ValidatorOnSubmit() == false) return false;");
        return;
    }
    if (this.Page.ClientScript.IsClientScriptBlockRegistered(typeof(BaseValidator), "ValidatorIncludeScript"))
    {
        return;
    }
    this.Page.ClientScript.RegisterClientScriptResource(typeof(BaseValidator), "WebUIValidation.js");
    this.Page.ClientScript.RegisterStartupScript(typeof(BaseValidator), "ValidatorIncludeScript", "\r\nvar Page_ValidationActive = false;\r\nif (typeof(ValidatorOnLoad) == \"function\") {\r\n    ValidatorOnLoad();\r\n}\r\n\r\nfunction ValidatorOnSubmit() {\r\n    if (Page_ValidationActive) {\r\n        return ValidatorCommonOnSubmit();\r\n    }\r\n    else {\r\n        return true;\r\n    }\r\n}\r\n        ", true);
    this.Page.ClientScript.RegisterOnSubmitStatement(typeof(BaseValidator), "ValidatorOnSubmit", "if (typeof(ValidatorOnSubmit) == \"function\" && ValidatorOnSubmit() == false) return false;");
}
