选择2；如何加载我从数据库加载一次的数组

Question

我正在加载一个包含以下操作结果的数组：

public ActionResult GetJudges(string q)
    {
        var judges = new List<Judge>();
        using (var con = new SqlConnection(ConfigurationManager.ConnectionStrings["db"].ConnectionString))
        {
            using (var cmd = con.CreateCommand())
            {
                cmd.CommandType = CommandType.Text;
                cmd.CommandText = "query";
                con.Open();
                using (var rdr = cmd.ExecuteReader())
                {
                    while (rdr.Read())
                    {
                        var judge = default(Judge);
                        var id = Convert.ToInt32(rdr["ID"]);
                        var email = Convert.ToString(rdr["Email"]);
                        var name = Convert.ToString(rdr["Name"]);
                        var jurisdiction = Convert.ToString(rdr["Jurisdiction"]);
                        var code= Convert.ToString(rdr["code"]);

                        if (!judges.Select(x => x.Id).Contains(id))
                        {
                            judge = new Judge
                            {
                                Id = id,
                                Email = email,
                                Name = name,
                                Code= code
                            };
                            judges.Add(judge);
                        }
                        else
                        {
                            judge = judges.FirstOrDefault(x => x.id == id);
                        }

                        judge.Jurisdictions.Add(jurisdiction);
                    }
                }
                con.Close();
            }
        }
        return Json(judges, JsonRequestBehavior.AllowGet);
    }

我试图将此数组加载到 Select2 元素中，但没有成功。 select2 元素始终为空。这是我用来加载 select2 的 javascript:

var judges = [];


    $(document).ready(function () {
        $.getJSON('/Home/GetJudges', function (result) {
            judges = result;
            $(".select2").select2({
                placeholder: "Search for a Judge",
                data: { results: result, id: "Id", text: "Text" }
            });
        });
    });

谁能告诉我这里缺少什么？

查看 this 示例，了解如何使用 select2。您传递的数据不正确。你的 result 应该包含一个对象数组，这些对象有一个 id 属性和一个 text 属性，你应该将它作为 [=14] 传递给 select2 =] 直接，而不是将其包装在另一个对象中。

//sample data
var result = [{id: 0, text: 'Judge 1'}, {id: 1, text: 'Judge 2'}];

$(".select2").select2({
    placeholder: "Search for a Judge",
    data: result
});
