我有一个 select2 选择菜单工作（来自远程地理字节的状态），但我无法选择具有相同索引 ID 的选项。例如，如果我搜索“新”，我会得到一些选项，我可以选择第一个选项 New Albany, IN。然后，如果我输入“far”，第一个选项是 Far Hills, NJ。当我选择它时，它显示 Albany, IN，它的索引为 1。

我尝试了加载远程数据的示例，https://select2.github.io/examples.html#data-ajax。它的行为方式不同，所以我想知道我是否错误地解析了我的结果。每次搜索时，它都会返回一个索引从 1 开始的新对象。

$('#input_3_4').select2({
      ajax: {
        url: "http://gd.geobytes.com/AutoCompleteCity?callback=?&template=%3Cgeobytes%20city%3E,%20%3Cgeobytes%20code%3E&filter=US",
        dataType: 'json',
        quietMillis: 1500,
        data: function (params) {
          return {
            q: params.term, // search term
            page: params.page
          };
        },
        processResults: function (data, params) {
          for(var i = 0; i < data.length; i++){
             data[i] = {id:i+1, text:data[i]};
          }
          // 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;
          console.log(data);
          return {
            results: data,
            pagination: {
              more: (params.page * 30) < data.total_count
            }
          };

        },
        cache: true,
      },
      escapeMarkup: function (markup) { return markup; }, // let our custom formatter work
      minimumInputLength: 3,
      //templateResult: formatRepo, // omitted for brevity, see the source of this page
      //templateSelection: formatRepoSelection // omitted for brevity, see the source of this page
   });
