Question

这是我试图迭代的响应字符串：

{
"page": 1,
"results": [
    {
        "adult": false,
        "backdrop_path": "/8uO0gUM8aNqYLs1OsTBQiXu0fEv.jpg",
        "id": 550,
        "original_title": "Fight Club",
        "release_date": "1999-10-15",
        "poster_path": "/2lECpi35Hnbpa4y46JX0aY3AWTy.jpg",
        "popularity": 61151.745000000003,

        "vote_average": 9.0999999999999996,
        "vote_count": 174
    },
    {
        "adult": false,
        "backdrop_path": "/5Z0FScA1bB6EbdGmZCUBeUk32eV.jpg",
        "id": 14476,
        "original_title": "Clubbed",
        "release_date": "2008-10-02",
        "poster_path": "/bl6PEQtmohEP1zP9srNZY6bXyHg.jpg",
        "popularity": 1.7290000000000001,
        "title": "Clubbed",
        "vote_average": 7.7999999999999998,
        "vote_count": 3
    },
    {
        "adult": false,
        "backdrop_path": "/qw2Qb42xtyE1B449JoTgb1mVCe1.jpg",
        "id": 51021,
        "original_title": "Lure: Teen Fight Club",
        "release_date": "2010-11-16",
        "poster_path": "/aRTX5Y52yGbVL6TGnyI4E8jjtz4.jpg",
        "popularity": 0.26600000000000001,
        "title": "Lure: Teen Fight Club",
        "vote_average": 0.0,
        "vote_count": 0
    },
    {
        "adult": false,
        "backdrop_path": "/tcoAGvTo96R7Y9ZGVCCz7BZvrvb.jpg",
        "id": 104782,
        "original_title": "Florence Fight Club",
        "release_date": "2010-01-01",
        "poster_path": "/eQqqu0srTYcclWqylvgpLyU87hV.jpg",
        "popularity": 0.085000000000000006,
        "title": "Florence Fight Club",
        "vote_average": 0.0,
        "vote_count": 0
    },
    {
        "adult": false,
        "backdrop_path": null,
        "id": 115584,
        "original_title": "Fight Club – The “I am Jack’s Laryngitis” Edit",
        "release_date": null,
        "poster_path": null,
        "popularity": 0.059999999999999998,
        "title": "Fight Club – The “I am Jack’s Laryngitis” Edit",
        "vote_average": 0.0,
        "vote_count": 0
    }
],
"total_pages": 1,
"total_results": 5
}

我想迭代结果并提取一些属性，例如original_title，release_date等。我尝试使用下面的代码（以及其他代码）尝试打印一行无效：

var data = JSON.parse(this.responseText);
alert(data.page[0].results[0].original_title);

Answer 1

page属性不是您要检索的预期结果集的一部分。试试这个：

alert(data.results[0].original_title);

Answer 2

删除.page[0]：

alert(data.results[0].original_title);

在Javascript中迭代JSON响应
