c# - nopCommerce 3.70 中的 bootstrap Mega Menu

Question

我正在 nopCommerce 3.70 网站上工作，我正在制作自定义 MagaMenu 下拉菜单，

我完成它的方法是创建一个 TopMenu.cshtml 文件，我将它放在我的主题文件夹下，所以它覆盖了默认值，并且我根据 Bootstrap 的 Maga 菜单制作了一些自定义助手和 css，对于移动我我仍在使用 DefaultClean 的标准，但我的整个想法只在主页上有效，所有其他页面的菜单都乱七八糟，我不知道为什么它在其他页面上不起作用，这是我的代码。

        $(document).ready(function () {
            $(".dropdown").hover(
                function () {
                    $('.dropdown-menu', this).stop().fadeIn("fast");
                },
                function () {
                    $('.dropdown-menu', this).stop().fadeOut("fast");
                });
          
            $('.menu-toggle').click(function () {
                $(this).siblings('.top-menu.mobile').slideToggle('slow');
            });
            $('.top-menu.mobile .sublist-toggle').click(function () {
                $(this).siblings('.sublist').slideToggle('slow');
            });
        });

代码都在TopMenu.cshtml页面里面，js被script标签包围，css被script标签包围，当然我在css中为@media做转义字符。

有人对此有意见吗？

你的菜单问题是你没有包含 Bootstrap。

nopCommerce 的任何版本都默认使用 Bootstrap，这就是每当发布新版本时开发人员都会发布支持 bootstrap 的主题的原因，如下所示:

Default Clean Theme Bootstrap version (Free)

您可以选择上面的主题并将您的菜单合并到那里，或者您自己将其包含在您的主题中。如果您选择后一种方法，请将 Bootstrap 解压缩到主题的内容文件夹中。

然后，从主题的 Shared 文件夹中的 _Root.Head.cshtml 文件中，添加对 Bootstrap 文件的引用，如下所示:

Html.AddScriptParts(ResourceLocation.Head, "~/Themes/THEMENAME/Content/BOOTSTRAPFOLDER/dist/js/bootstrap.min.js");
Html.AddCssFileParts(ResourceLocation.Head, "~/Themes/THEMENAME/Content/BOOTSTRAPFOLDER/dist/css/bootstrap.min.css");

我目前正在自己​​开发一个 3.70 Bootstrap 主题——这是我用来合并 bootstrap 的方法。
