我正在尝试使用 Select2 并在 Aurelia 中加载远程数据（ajax）。因此，我创建了一个名为Select2并遵循文档中的选项的自定义属性。

但是，当我滚动到下拉列表的末尾时，我遇到了一个问题，出现“正在加载更多结果”消息，但没有加载更多数据或调用 API（使用 Select2 文档中的相同 API 以确保我没有遗漏任何东西）。

import { customAttribute, inject , bindable, bindingMode} from 'aurelia-framework';
import 'jquery';
import 'select2'; 

@customAttribute('select2')
@inject(Element)
export class Select2CustomAttribute {
    element;

    constructor(element) {
        this.element = element;
    }

    attached() {

               var self=this;

        $(this.element).select2(
            {
               // closeOnSelect: false,
                 allowClear: true,        
                ajax: {
    url: "https://api.github.com/search/repositories",
    dataType: 'json',
    delay: 250,
    data: function (params) {
      return {
        q: params.term, // search term
        page: params.page
      };
    },
    processResults: function (data, params) {
      // parse the results into the format expected by Select2
      // since we are using custom formatting functions we do not need to
      // alter the remote JSON data, except to indicate that infinite
      // scrolling can be used
      params.page = params.page || 1;

      return {
        results: data.items,
        pagination: {
          more: (params.page * 30) < data.total_count
        }
      };
    },
    cache: true
  },
                escapeMarkup: function (markup) { return markup; }, 
                minimumInputLength:0,
                templateResult: function( repo )
                            {
                                if (repo.loading) return repo.text;

      var markup = "<div class='select2-result-repository clearfix'>" +
        "<div class='select2-result-repository__avatar'><img src='" + repo.owner.avatar_url + "' /></div>" +
        "<div class='select2-result-repository__meta'>" +
          "<div class='select2-result-repository__title'>" + repo.full_name + "</div>";

      if (repo.description) {
        markup += "<div class='select2-result-repository__description'>" + repo.description + "</div>";
      }

      markup += "<div class='select2-result-repository__statistics'>" +
        "<div class='select2-result-repository__forks'><i class='fa fa-flash'></i> " + repo.forks_count + " Forks</div>" +
        "<div class='select2-result-repository__stargazers'><i class='fa fa-star'></i> " + repo.stargazers_count + " Stars</div>" +
        "<div class='select2-result-repository__watchers'><i class='fa fa-eye'></i> " + repo.watchers_count + " Watchers</div>" +
      "</div>" +
      "</div></div>";

      return markup;

                            },
                             templateSelection: function (repo) { return repo.full_name || repo.text; } ,

            }
        ).on('change', evt => {
                if (!evt.originalEvent) {
                    try{
                        this.element.dispatchEvent(new Event('change'));
                    }catch(e){
                        // IE 11+
                        try{
                            let evt = document.createEvent('HTMLEvents');
                            evt.initEvent('change', false, true);
                            this.element.dispatchEvent(evt);
                        }catch(e){
                            console.log(e);
                        }
                    }
                }
            });

}
}

我将您的代码复制到 gist.run 中，它运行良好：https ://gist.run/?id=5b560eac6deff0f1b0896c30a3f12f79

唯一的区别是我从 CDN 加载 jQuery 和 select2 而不是从包中加载。你可以在这里看到它的 GIF：http: //imgur.com/a/6uSs6
