jQuery自动完成与JSON响应

Question

即时通讯在JSON中获取响应，但这不会解析JSON响应。我在做什么错？我在doc
http://docs.jquery.com/Plugins/Autocomplete上找不到任何内容

$("#users-allowed").autocomplete("/people/following.json", {
  width: 320,
  //max: 4,
  highlight: false,
  scroll: true,
  scrollHeight: 300,
  formatItem: function(response, i, max) {
    console.log(response);
    console.log(response['items']);
    console.log(response.items);
    return i + "/" + max + ": \"" + response.status_code + "\" [" + response.status_description + "]";

    //return "<img src='images/" + value + "'/> " + value.split(".")[0];
  },
  formatResult: function(response) {
    //return value.split(".")[0];
    return response.status_description;
  }
});

Answer 1

$("#users-allowed").autocomplete("/people/following.json", {
  width: 320,
  dataType: 'json',
  highlight: false,
  scroll: true,
  scrollHeight: 300,
  parse: function(data) {
    var array = new Array();
    for(var i=0;i<data.items.length;i++) {
      array[array.length] = { data: data.items[i], value: data.items[i], result: data.items[i].username };
    }
    return array;
  },
  formatItem: function(row) {               
    var name = '';
    if (row.first_name && row.last_name)
      name = '('+row.first_name+', '+row.last_name+')';
    else if (row.first_name)
      name = '('+row.first_name+')';
    else if (row.last_name)
      name = '('+row.last_name+')';

    return row.username+' '+name;
  }
});

检查dataType和parse选项。
