Question

以下是我的JSON对象

var data = [{"city":"Oslo","cityCode":"OSL","airport":"Oslo - All airports","airportCode":"OSL","country":"Norway","localName":"Gardermoen","europeFlag":true,"airlines":["SK","WF"],"distance":0.0}]

我正在尝试使用JSON数据进行自动完成。在键入OSL（cityode）时，我想在下拉列表中显示OSLO（城市），反之亦然。

我使用了下面的代码但是它返回空值

JQUERY：

$(document).ready(function(){
     var data = [{"city":"Oslo","cityCode":"OSL","airport":"Oslo - All airports","airportCode":"OSL","country":"Norway","localName":"Gardermoen","europeFlag":true,"airlines":["SK","WF"],"distance":0.0}]

    $("#meta-area").autocomplete({
        source:data,
        select: function(e, ui) {
            e.preventDefault() 
            $("#meta_search_ids").val(ui.item.cityCode);

            $(this).val(ui.item.city);
        }
    });

});

HTML：

<input type='text' size='20' id='meta-area' />
<input type='hidden' id='meta_search_ids' value='' />

请帮助我获取价值。谢谢提前
