ASP.NET MVC视图中动态生成的javascript

我有一个数据库，里面有一些Java脚本。显示给用户的文本因章节和语言而异。使用存储过程提取所需的正确脚本。然后在控制器中将其分配给ViewBag。然后，它将显示在视图上。除了一个障碍外，每件事情都很好，那就是在我的Javascript周围添加jQuery函数，这使得它无法工作。我在控制器中设置了一个断点，可以清楚地看到它在控制器上没有jQuery函数。我想如果我加上剧本 标记，然后使用Html.Raw将其写入视图，这样它可能会修复它，但不会

这是控制器中的代码

 public ActionResult Personality(int AssessmentID, int ProfileID, int LanguageID)
    {
        string script = "<script type=\"text/javascript\">";
        var questions = db.CRI_AssessmentQuestions.Where(a => a.SectionID == 1 && a.LanguageID == LanguageID).OrderBy(a => a.Sequence);
        using (SqlConnection oConn = new SqlConnection(ConfigurationManager.ConnectionStrings["CRI_Support"].ConnectionString))
        {
            SqlCommand oCmd = new SqlCommand();
            object pages;
            oCmd.CommandText = "CRI_GetSectionCount";
            oCmd.CommandType = CommandType.StoredProcedure;
            oCmd.Parameters.Add(new SqlParameter("@AssessmentID", AssessmentID));
            oCmd.Connection = oConn;
            oConn.Open();
            pages = oCmd.ExecuteScalar();
            oConn.Close();
            oCmd.Dispose();
            ViewBag.NumPages = pages.ToString();

            SqlCommand myCmd = new SqlCommand();
            object mids;
            myCmd.CommandText = "CRI_GetAllowedMiddles";
            myCmd.CommandType = CommandType.StoredProcedure;
            myCmd.Parameters.Add(new SqlParameter("@AssessmentID", AssessmentID));
            myCmd.Connection = oConn;
            oConn.Open();
            mids = myCmd.ExecuteScalar();
            oConn.Close();
            myCmd.Dispose();
            ViewBag.Middles = mids.ToString();

            SqlCommand tCmd = new SqlCommand();
            object totalQ;
            tCmd.CommandText = "PersonalityQuestionCount";
            tCmd.CommandType = CommandType.StoredProcedure;
            tCmd.Parameters.Add(new SqlParameter("@AssessmentID", AssessmentID));
            tCmd.Connection = oConn;
            oConn.Open();
            totalQ = tCmd.ExecuteScalar();
            oConn.Close();
            tCmd.Dispose();

            SqlCommand cmd = new SqlCommand();
            Object returnValue;
            cmd.CommandText = "CRI_GetNewScript";
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.Add(new SqlParameter("@SectionID", 1));
            cmd.Parameters.Add(new SqlParameter("@LanguageID", LanguageID));
            cmd.Connection = oConn;
            oConn.Open();
            returnValue = cmd.ExecuteScalar();
            oConn.Close();
            cmd.Dispose();
            script += returnValue.ToString() + "</script>";
            script = script.Replace("#iPageNumber#", "1").Replace("#iTotalPages#", pages.ToString()).Replace("#iAllowedMiddles#", mids.ToString()).Replace("#TotalQuestions#", totalQ.ToString());
        }
        ViewBag.Script = script;
        ViewBag.AssessmentID = AssessmentID;
        ViewBag.ProfileID = ProfileID;
        ViewBag.LanguageID = LanguageID;
        return View(questions);
    }

这是要归还的东西

我需要做些什么才能使它正确显示？

查看

Personality.cshtml

视图。在那里你可以找到

（函数（$）{

code

我找到了原因。我在项目中有MVC控件工具包

有以下代码

 public static class MySuperPackage {
    public static void PreStart() {
        MVCControlsToolkit.Core.Extensions.Register();
        //System.Web.Mvc.GlobalFilters.Filters.Add(new MVCControlsToolkit.ActionFilters.PlaceJavascriptAttribute());
    }
}

注释添加过滤器解决了这个问题

我认为Eduardo正确地解决了这个问题，但作为旁白，您不应该在视图中填充所需的变量。创建视图包是为了让您能够在_Layout.cshtml的视图范围之外访问这些变量。使用您希望您的视图能够访问的属性，然后初始化它并在控制器中填充它的值，并将其传递给您的视图。如果这是实际的代码，那么这里还发生了其他事情。您的函数使用

“

”构建脚本，这将是unescape之后的

，但是您的“返回内容”显示

。请注意引号和间距的差异。很明显，这里没有显示某些内容。是的，我也看到了。

(function($){
})(jQuery);

 public static class MySuperPackage {
    public static void PreStart() {
        MVCControlsToolkit.Core.Extensions.Register();
        //System.Web.Mvc.GlobalFilters.Filters.Add(new MVCControlsToolkit.ActionFilters.PlaceJavascriptAttribute());
    }
}
