Index.cshtml：（这是我的脚本收到错误的地方）

<script type="text/javascript">

        popup.Show();
    }

    function PrepareValidationScripts(form) {
        if (!form)
            return;
        if (form.attr("data-executed"))
            return;
        $.validator.unobtrusive.parse(form); // <----- this is where I get the error
        form.attr("data-executed", "true");
    }
</script>

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

在你的布局中，首先应该包含jQuery，然后是jQueryval：

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

原因是因为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之后其他主要脚本的专用部分中：

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

然后在视图中将所有脚本放在此部分中，以便保留订单：

@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<head>中的专用部分。

不完全了解捆绑，这里有什么问题？
