Ajax请求Select2 - Resultlist始终为空

Question

我尝试使用带有ajax的Select 2插件作为数据源，但我总是收到＆＃34;未找到结果＆＃34;在结果列表中，键入一些字母后。我希望它会在我的搜索结果中列出我的Ajax响应中找到的所有项目（Field：LastName）。我在本文末尾附上了ajax回复。

我的HTML选择元素：

<select class="player-select form-control">
</select>

我的Select2 JS：

jQuery(document).ready(function() {
    $(".player-select").select2({
        ajax: {
            url: "/database/players.php",
            dataType: "json",
            delay: 250,
            processResults: function (data) {
                // 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
                return {
                    results: data.LastName
                };
            }
        },
        minimumInputLength: 1,
    })
});

我的AJAX响应：

您的processResults方法会略有不同，因为您尝试在每个项目上获得与LastName匹配的自定义结果。我已经添加了评论，以便您知道必须做些什么。

processResults: function(data, params) {
  var resData = [];//just to store matching data
  //iterate through each data
  data.forEach(function(value) {
    //check if the LastName param contains the search param entered
    if (value.LastName.indexOf(params.term) != -1)
      resData.push(value)//push the item to resData array
  })
  return {
    results: $.map(resData, function(item) {
      //now while returning you need to map the array text and id property since you are
      //returning custom query
      return {
        text: item.LastName,
        id: item.Id
      }
    })
  };
},
