Jquery ui 在CakePHP2.0中使用JQuery UI自动完成

我在CakePHP2.0中实现jQueryUIAutoComplete时遇到问题。希望在杂货店列表视图中显示项目列表，以允许用户选择数据库中已有的项目，而不是创建新项目

应用程序Jquery：

视图中的项目窗体：

我不知所措，欢迎任何意见

在对Application.js进行了上述更改之后，我的网页上现在有了响应。根据数据库中当前包含的内容，它具有正确数量的结果，但是它是一个空响应。Firebug的回复如下：

[{"value":null,"label":null},{"value":null,"label":null},{"value":null,"label":null},{"value":null,"label":null}]

以下是我的回复标题：

我不太清楚您在问什么，但以下是我在CakePHP 1.2和1.3中使用的Javascript：

$.ajax({
  url: '/api/v1/zip_codes/utilities/' + zip + '/' + type + '.json',
  type: 'GET',
  dataType: 'json',
  success: function( data, status ) {
    var utility_type = data.Type.name;

    var $provider_name = $('#Building' + utility_type + 'ProviderName');
    var $provider_id   = $('#Building' + utility_type + 'ProviderId');

    // Massage the Cake data into something autocomplete-friendly
    var $friendly = $.map( data.Utilities, function( util ) {
    return { label: util.Utility.name, value: util.Utility.id };
  });

  // If more than one, populate the provider autocomplete options
  $provider_name.autocomplete({
    source: $friendly, // use the autocomplete-friendly data
    minLength: 0,
    focus: function( event, ui ) {
      $provider_name.val( ui.item.label );
      return false;
    },
    select: function( event, ui ) {
      $provider_name.val( ui.item.label );
      $provider_id.val( ui.item.value );
      return false;
    }
  }).data( 'autocomplete' )._renderItem = function( ul, item ) {
    return $( "<li></li>" )
      .data( "item.autocomplete", item )
      .append( '<a>' + item.label + '</a>' )
      .appendTo( ul );
  };
});

此代码段检索在给定邮政编码下运营的公用事业公司的名称和ID，只是为了提供一点上下文。有关更多信息，请参阅。我正在完成XHR加载：当我搜索蛋糕时。虽然问题解决了，但没有打印出任何内容，但不清楚原因。我怀疑Jquery不喜欢[][]

[{"value":null,"label":null},{"value":null,"label":null},{"value":null,"label":null},{"value":null,"label":null}]
