Question

我正在阅读这里的教程：https://docs.microsoft.com/en-us/aspnet/web-api/overview/getting-started-with-aspnet-web-api/using-web-api-with-aspnet-web-forms

注意：本教程使用的是Visual Studio 2012（我相信），我使用的是Visual Studio 2015。

我正在运行Chrome。

它似乎无法识别jQuery文件。是不是及时加载？注意：我的屏幕截图中有一个jQuery选项卡及其内容。

我收到错误 - 默认值：34未捕获的ReferenceError：$未定义：

这是default.aspx页面：

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Products._Default" %>
  
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">

    <script type="text/javascript">
        function getProducts() {
            $.getJSON("api/products",
                function (data) {
                    $('#products').empty(); // Clear the table body.

                    // Loop through the list of products.
                    $.each(data, function (key, val) {
                        // Add a table row for the product.
                        var row = '<td>' + val.Name + '</td><td>' + val.Price + '</td>';
                        $('<tr/>', { text: row })  // Append the name.
                            .appendTo($('#products'));
                    });
                });
            }

        // Executes when the document loads.
        $(document).ready(getProducts);
    </script>
</asp:Content>

<%-- A content server control that points to the master pages "content place holder" area (MainContent) where this content page will be placed. --%>
