加载失败的select2搜索

Question

使用Ajax在select2框中搜索内容时，出现“加载失败”错误。我的代码如下：

enter code here.

搜索文字：

<div>@Html.Hidden("cod_indem", ViewBag.cod_indem as object)</div>

     $(function () {
     $("#cod_indem").select2(
            {
                width: "100%",
                ajax: {
                    type: "Get",

                    url: '@(Url.Action("GetAll", "Zpy_paye"))',
                    cache: false,

                    dataType: 'json',

                    delay: 250,
                    data: function (term, page) {
                        return {
                            match: term, // search term
                            pageIndex: page,
                            pageSize: 30
                        };
                    },
                    results: function (data, page) {
                        page = page || 1;
                        return {
                            results: data.items,
                            more: (page * 30) < data.total_count

                        };
                    }
                },

                escapeMarkup: function (markup) { return markup; },
                minimumInputLength: 3,
                formatSelection: format,
                formatResult: format

            });
        });


        function format(data) {
            return   data.text;

        }
