javascript – Bloodhound.js：转换远程源返回的数据？

我正在使用Bloodhound和远程API,我需要转换从远程API返回的结果.

API URL为https://www.googleapis.com/books/v1/volumes?q=quilting,返回具有项属性(列表)的对象.我需要将该列表返回给Typeahead,而不是顶级对象.

Bloodhound文档说there is a transform function that is supposed to do this,但我不能让它工作.

这是我的代码：

var books = new Bloodhound({
  datumTokenizer: function(d) { return Bloodhound.tokenizers.whitespace(d.num); },queryTokenizer: Bloodhound.tokenizers.whitespace,remote: {
    url: 'https://www.googleapis.com/books/v1/volumes?q=quilting'
  },transform: function(response) {
    console.log('transform',response);
    return response.items;
  }
});
books.initialize();

// instantiate the typeahead UI
$('#myTextBox').typeahead(null,{
  displayKey: function(suggestion) {
    console.log('suggestion',suggestion);
    return suggestion.volumeInfo.title + suggestion.volumeInfo.publishedDate;
  },source: numbers.ttAdapter()
});

这里有一个JSFIddle：http://jsfiddle.net/2Cres/46/

这不起作用,因为我需要将项目列表提供给预先输入的UI,但这似乎并没有发生.

remote {
  url:"fdsfds",transform: function (response){...}
}
