jquery - 使用 jquery 调用 "imdbapi.com"

Question

我正在尝试根据函数中的电影标题从 IMDB 获取电影海报。

我已经尝试过:

function getPoster(title)
{
    $.ajax({
      url: "http://www.imdbapi.com/?t=" + title,
      datatype: "json",
      success: return data
    });
}

但我真的不知道如何“返回”从 .ajax() 获得的数据...

edit IMDBapi 返回一个 json 数据集，如下所示:

{"Title":"Jurassic Park","Year":"1993","Rated":"PG-13","Released":"11 Jun 1993","Genre":"Action, Adventure, Family, Sci-Fi","Director":"Steven Spielberg","Writer":"Michael Crichton, Michael Crichton","Actors":"Sam Neill, Laura Dern, Jeff Goldblum, Richard Attenborough","Plot":"During a preview tour, a theme park suffers a major power breakdown that allows its cloned dinosaur exhibits to run amok.","Poster":"http://ia.media-imdb.com/images/M/MV5BMTc2NDIxNTQyNF5BMl5BanBnXkFtZTcwNzIwMzM3MQ@@._V1._SX320.jpg","Runtime":"2 hrs 7 mins","Rating":"7.9","Votes":"159458","ID":"tt0107290","Response":"True"}

编辑2:这有效:

for(var i in titles)
{
    $.ajax({
      url: "http://www.imdbapi.com/?t=" + titles[i],
      dataType: 'jsonp',
      success: function(data) {
        $('body').append(data.Poster+'<br />');
      }
    });
}

Answer 1

你不能。

AJAX 是异步；您只有在函数返回后才能收到服务器的回复。

相反，您可以让您的函数接受回调，就像 $.ajax 那样。
