未捕获的类型错误：$(...).jqGrid 不是函数

Question

我知道这是一个愚蠢的问题，但是当我使用 ado.net 时我无法弄清楚这个问题。我可以通过使用实体框架按预期运行和使用 jqgrid，但是当我使用 ado.net 时出现此错误。请帮助。几乎敲我的头。我正在附上代码。提前致谢。

$(function ()
{
    $("#ListGrid").jqGrid
        ({
        url: "/TodoList/GetTodoLists",
        datatype: 'json',
        mtype: 'Get',
        colNames: ['Firstname', 'Gender', 'Id', 'LastName', 'Salary'],
        colModel: [
            { key: false, name: 'Firstname', index: 'Firstname', editable: true },
            { key: false, name: 'Gender', index: 'Gender', editable: true },
            { key: true, hidden: true, name: 'Id', index: 'Id', editable: true },
            { key: false, name: 'LastName', index: 'LastName', editable: true },
            { key: false, name: 'Salary', index: 'Salary', editable: true }],
        pager: jQuery('#pager'),
        rowNum: 10,
        rowList: [10, 20, 30, 40],
        loadonce: true,
        height: '100%',
        viewrecords: true,
        caption: 'Todo List',
        emptyrecords: 'No records to display',
        jsonReader: {
            root: "rows",
            page: "page",
            total: "total",
            records: "records",
            repeatitems: false,
            Id: "0"
        },
        autowidth: true,
        multiselect: false
    });
});

    ViewBag.Title = "TodoList";

在这种情况下，_Layout.cshtml 中有两个对 jquery 库的引用，必须删除（*如果您在 cshtml 文件中包含库标记）才能完全运行脚本，否则您将得到相同的错误。
