错误：0x800a138f - Microsoft JScript 运行时错误：无法获取属性“unobtrusive”的值：对象为空或未定义

底部列出的 Index.cshtml 是我出现问题的地方。

BundleConfig.cs：

                      "~/Scripts/jquery-{version}.js"));

          bundles.Add(new ScriptBundle("~/bundles/jqueryui").Include(
                      "~/Scripts/jquery-ui-{version}.js"));

          bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(

在您的布局中，您应该首先包含 jQuery，然后包含 jQueryval：

Scripts.Render("~/bundles/jquery"); 
Scripts.Render("~/bundles/jqueryval");

这是因为 jQuery.validate 插件依赖于 jQuery，并且包含脚本的顺序很重要。

另外，我建议您将所有自定义脚本放在一个专门的部分中，该部分位于其他主要脚本之后：

Scripts.Render("~/bundles/jquery"); 
Scripts.Render("~/bundles/jqueryval");
RenderSection("Scripts", required: false)

然后在您的视图中将所有脚本放在此部分中，以便保留顺序：

@section Scripts {
    <script type="text/javascript">
        function displaySuccess(result) {
            popup.Show();
        }

        function PrepareValidationScripts(form) {
            if (!form)
                return;
            if (form.attr("data-executed"))
                return;
            $.validator.unobtrusive.parse(form);
            form.attr("data-executed", "true");
        }
    </script>
}

@{
    //this is where I render my partial views
    <snip.....>
    <snip.....>
    <snip.....>
 }

当然，您的 CSS 样式也是如此。您应该将它们放在文档中专门的部分中<head>。
