function fetchJSON(start,keyword){
        var data;
        $.getJSON("http://api.douban.com/movie/subjects?alt=xd&callback=?&st
art-index="+start+"&max-results=1&q="+$("#autofetch").val(),function(data){
                        var id=data.entry[0].id['$t'];
                        $.getJSON(id+"?alt=xd&callback=?", function(data){
                                return data;
                        })
        })
}

为什么我得到的返回都是undefined呢？
