Asp.net Net MVC Recaptcha和严格的Doctype

我在我的MVC项目中使用了这种Recaptcha方法，但是它不能验证为严格的1.0 DOCTYPE

有人能帮忙吗

谢谢

创建您自己的控件。正如您在RecaptchaControl的RenderContents方法中所看到的，它使用iframe。Iframe不是严格遵从HTML的，因此必须使用HTML对象标记

protected override void RenderContents(HtmlTextWriter output)
{
 output.AddAttribute(HtmlTextWriterAttribute.Type, "text/javascript");
 output.RenderBeginTag(HtmlTextWriterTag.Script);
 output.Indent++;
 output.WriteLine("var RecaptchaOptions = {");
 output.Indent++;
 output.WriteLine("theme : '{0}',", this.theme ?? string.Empty);
 if (this.customThemeWidget != null)
 {
  output.WriteLine("custom_theme_widget : '{0}',", this.customThemeWidget);
 }
 output.WriteLine("tabindex : {0}", this.TabIndex);
 output.Indent--;
 output.WriteLine("};");
 output.Indent--;
 output.RenderEndTag();
 output.AddAttribute(HtmlTextWriterAttribute.Type, "text/javascript");
 output.AddAttribute(HtmlTextWriterAttribute.Src, this.GenerateChallengeUrl(false), false);
 output.RenderBeginTag(HtmlTextWriterTag.Script);
 output.RenderEndTag();
 output.RenderBeginTag(HtmlTextWriterTag.Noscript);
 output.Indent++;
 output.AddAttribute(HtmlTextWriterAttribute.Src, this.GenerateChallengeUrl(true), false);
 output.AddAttribute(HtmlTextWriterAttribute.Width, "500");
 output.AddAttribute(HtmlTextWriterAttribute.Height, "300");
 output.AddAttribute("frameborder", "0");
 output.RenderBeginTag(HtmlTextWriterTag.Iframe); // Change this to object HTML tag
 output.RenderEndTag();
 output.WriteBreak();
 output.AddAttribute(HtmlTextWriterAttribute.Name, "recaptcha_challenge_field");
 output.AddAttribute(HtmlTextWriterAttribute.Rows, "3");
 output.AddAttribute(HtmlTextWriterAttribute.Cols, "40");
 output.RenderBeginTag(HtmlTextWriterTag.Textarea);
 output.RenderEndTag();
 output.AddAttribute(HtmlTextWriterAttribute.Name, "recaptcha_response_field");
 output.AddAttribute(HtmlTextWriterAttribute.Value, "manual_challenge");
 output.AddAttribute(HtmlTextWriterAttribute.Type, "hidden");
 output.RenderBeginTag(HtmlTextWriterTag.Input);
 output.RenderEndTag();
 output.Indent--;
 output.RenderEndTag();
}

您想要什么帮助？为了让它通过严格的doctype验证，我刚刚查看了源代码，它使用了iframe，因此无论如何都不会通过。羞耻。recaptcha Group的人建议我使用HTML5 Doctype-我添加了HTML5 Doctype，但由于iframe上的frameborder属性，它仍然失败。您希望得到什么帮助？为了让它通过严格的Doctype验证，我只查看了源代码，它使用了iframe，所以无论如何都不会通过。羞耻。recaptcha Group的人建议我使用HTML5 Doctype——我添加了HTML5 Doctype，但由于iFrame上的frameborder属性，它仍然失败
