我正在以我的一个注册表格
实施验证码在Example.Cs文件中,我写了以下内容:
public static class CaptchaHelper
{
public static string Captcha(this HtmlHelper helper, string text)
{
string srcPath = System.Web.VirtualPathUtility.ToAbsolute("~/Handler1.ashx");
string htmlContent = string.Empty;
htmlContent += "<script type=\"text/javascript\">function __rc(){document.getElementById(\"" + text +
"\").src = \"../Handler1.ashx?query=\" + Math.random();}</script>";
htmlContent += string.Format("<img id=\"{0}\" src=\"{1}\" alt=\"Captcha Image\"/>", text, srcPath);
htmlContent += "<a href=\"#\" onclick=\"javascript:__rc();\">Reset</a>";
return htmlContent;
}
}
在View(.cshtml)中,我写了以下内容:
@Html.Captcha("Sample")
代替图像,显示脚本可以为此提供任何帮助。

试试这个...
public static class CaptchaHelper
{
public static MvcHtmlString Captcha(this HtmlHelper helper, string text)
{
string srcPath = System.Web.VirtualPathUtility.ToAbsolute("~/Handler1.ashx");
string htmlContent = string.Empty;
htmlContent += "<script type=\"text/javascript\">function __rc(){document.getElementById(\"" + text +
"\").src = \"../Handler1.ashx?query=\" + Math.random();}</script>";
htmlContent += string.Format("<img id=\"{0}\" src=\"{1}\" alt=\"Captcha Image\"/>", text, srcPath);
htmlContent += "<a href=\"#\" onclick=\"javascript:__rc();\">Reset</a>";
return MvcHtmlString.Create(htmlContent.ToString());
}
}
编辑...试试这一行......
htmlContent += string.Format("<img id=" + text + " src=" + srcPath + " alt=\"Captcha Image\"/>", text, srcPath);
