        $ajax.select2({
            ajax: {
                url: "/TestSelect2DropDown/GetCountries",
                dataType: 'json',
                delay: 250,
                data: function (params) {
                    return {
                        q: params.term, // search term
                        page: params.page
                    };
                },
                processResults: function (data, params) {
                    params.page = params.page || 1;

                    return {
                        results: data.result.items,
                        pagination: {
                            more: (params.page * 30) < data.result.totalCount
                        }
                    };
                },
                cache: true
            },
            escapeMarkup: function (markup) { return markup; },
            minimumInputLength: 1,
            templateResult: formatRepo,
            templateSelection: formatRepoSelection
        });

        function formatRepo(repo) {
            if (repo.loading) return repo.displayText;

            var markup = "<div class='select2-result-repository clearfix'>" +
                "<div class='select2-result-repository__title'>" + repo.displayText + "</div>";
            if (repo.displayText) {
                markup += "<div class='select2-result-repository__description'>" + repo.displayText + "</div>";
            }
            markup += "<div class='select2-result-repository__statistics'>" +
            "</div></div>";
            return markup;
        }

        function formatRepoSelection(repo) {
            return repo.displayText;
        }

＆＃13;

            <select class="js-example-data-ajax form-control">
                <option value="3620194" selected="selected">select2/select2</option>
            </select>

我尝试在select2下拉列表中使用ajax获取数据。我得到数据但是当我尝试选择一个元素时，它会被选中。此下拉没有滚动显示其他页面中的数据 有什么想法可以解决这个问题吗？
