Question

我试图调用bootstrap-datepicker，从这里查看类似的问题我认为我正确引用它但是当我打开chrome开发人员时，jQuery没有定义，开发者的图片链接截图以下

BundlesConfig

    public static void RegisterBundles(BundleCollection bundles)
    {
        bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                    "~/Scripts/jquery-{version}.js"));

        bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
                    "~/Scripts/jquery.validate*"));

        bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
                    "~/Scripts/modernizr-*"));

        bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
                    "~/Scripts/bootstrap.js",
                    "~/Scripts/respond.js"));

        bundles.Add(new StyleBundle("~/Content/css").Include(
                    "~/Content/bootstrap.css",
                    "~/Content/site.css"));

        bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                    "~/Scripts/jquery.unobtrusive-ajax.min.js"));

        bundles.Add(new ScriptBundle("~/bundles/bootstrap-datetimepicker").Include(
                        "~/Scripts/moment.js",
                        "~/Scripts/bootstrap-datetimepicker.js"));

        bundles.Add(new StyleBundle("~/Content/bootstrap-datetimeicker").Include(
                        "~/Content/bootstrap-datetimepicker.min.css"));

Scripts folder

Answer 1

您将从屏幕截图中看到jquery未作为其中一个脚本加载，这总是意味着您忘记在该页面上包含jquery软件包。

@section scripts{
    @Scripts.Render("~/bundles/jquery") // <-- this'll probably fix it
    @Scripts.Render("~/bundles/jqueryval")
    @Scripts.Render("~/bundles/bootstrap-datetimepicker")

或者，您可能忘记在“布局”中包含该部分

@Styles.Render("~/Content/css")
@RenderSection("styles", required: false)
@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/modernizr")
@RenderSection("scripts", required: false) // <-- placed *after* the jquery bundle

在这种情况下，您不应该直接将它包含在脚本部分中。
