为什么没有正确解析这个JSON？

Question

我的问题是这个JSON没有被JavaScript或jQuery API解析.我包含下面的代码和JSON输出的URL.

这个JSON在JavaScript中被解析为什么都没有:

//something like this:
alert(data); // gives an object
alert(data.horas[0].hora; // gives undefined

JSON本身:

{"horas": [{"hora": "13:20","filmes":[{ "tittle": "A Idade do Gelo 3 - Despertar dos Dinossauros VP3D ", "description": "", "image_url": "images/cartazes/img/a_idade_do_gelo_3_despertar_dos_dinossauros.jpg"}]},{"hora": "15:50","filmes":[{ "tittle": "A Idade do Gelo 3 - Despertar dos Dinossauros VP3D ", "description": "", "image_url": "images/cartazes/img/a_idade_do_gelo_3_despertar_dos_dinossauros.jpg"}]},{"hora": "18:00","filmes":[{ "tittle": "A Idade do Gelo 3 - Despertar dos Dinossauros VP3D ", "description": "", "image_url": "images/cartazes/img/a_idade_do_gelo_3_despertar_dos_dinossauros.jpg"}]},{"hora": "21:05","filmes":[{ "tittle": "A Idade do Gelo 3 - Despertar dos Dinossauros VP3D ", "description": "", "image_url": "images/cartazes/img/a_idade_do_gelo_3_despertar_dos_dinossauros.jpg"}]},{"hora": "13:40","filmes":[{ "tittle": "Igor ", "description": "", "image_url": "images/cartazes/img/igor.jpg"}]},{"hora": "16:10","filmes":[{ "tittle": "Igor ", "description": "", "image_url": "images/cartazes/img/igor.jpg"}]},{"hora": "21:30","filmes":[{ "tittle": "Bruno ", "description": "", "image_url": "images/cartazes/img/bruno.jpg"}]},{"hora": "13:00","filmes":[{ "tittle": "Harry Potter e o príncipe Misterioso ", "description": "", "image_url": "images/cartazes/img/harry_potter_e_o_principe_misterioso.jpg"}]},{"hora": "16:30","filmes":[{ "tittle": "Harry Potter e o príncipe Misterioso ", "description": "", "image_url": "images/cartazes/img/harry_potter_e_o_principe_misterioso.jpg"}]},{"hora": "20:30","filmes":[{ "tittle": "Harry Potter e o príncipe Misterioso ", "description": "", "image_url": "images/cartazes/img/harry_potter_e_o_principe_misterioso.jpg"}]},{"hora": "00:15","filmes":[{ "tittle": "O Barco do Rock ", "description": "", "image_url": "images/cartazes/img/o_barco_do_rock.jpg"}]},{"hora": "12:30","filmes":[{ "tittle": "O Barco do Rock ", "description": "", "image_url": "images/cartazes/img/o_barco_do_rock.jpg"}]},{"hora": "15:25","filmes":[{ "tittle": "O Barco do Rock ", "description": "", "image_url": "images/cartazes/img/o_barco_do_rock.jpg"}]},{"hora": "18:20","filmes":[{ "tittle": "O Barco do Rock ", "description": "", "image_url": "images/cartazes/img/o_barco_do_rock.jpg"}]},{"hora": "00:20","filmes":[{ "tittle": "Harry Potter e o príncipe Misterioso ", "description": "", "image_url": "images/cartazes/img/harry_potter_e_o_principe_misterioso.jpg"}]},{"hora": "13:30","filmes":[{ "tittle": "Harry Potter e o príncipe Misterioso ", "description": "", "image_url": "images/cartazes/img/harry_potter_e_o_principe_misterioso.jpg"}]},{"hora": "17:10","filmes":[{ "tittle": "Harry Potter e o príncipe Misterioso ", "description": "", "image_url": "images/cartazes/img/harry_potter_e_o_principe_misterioso.jpg"}]},{"hora": "13:10","filmes":[{ "tittle": "Cinco Minutos de Paz ", "description": "", "image_url": "images/cartazes/img/cinco_minutos_de_paz.jpg"}]},{"hora": "16:00","filmes":[{ "tittle": "Cinco Minutos de Paz ", "description": "", "image_url": "images/cartazes/img/cinco_minutos_de_paz.jpg"}]},{"hora": "18:30","filmes":[{ "tittle": "Cinco Minutos de Paz ", "description": "", "image_url": "images/cartazes/img/cinco_minutos_de_paz.jpg"}]},{"hora": "21:40","filmes":[{ "tittle": "Cinco Minutos de Paz ", "description": "", "image_url": "images/cartazes/img/cinco_minutos_de_paz.jpg"}]},{"hora": "00:00","filmes":[{ "tittle": "A Proposta ", "description": "", "image_url": "images/cartazes/img/a_proposta.jpg"}]},{"hora": "12:50","filmes":[{ "tittle": "A Proposta ", "description": "", "image_url": "images/cartazes/img/a_proposta.jpg"}]},{"hora": "15:40","filmes":[{ "tittle": "A Proposta ", "description": "", "image_url": "images/cartazes/img/a_proposta.jpg"}]},{"hora": "18:10","filmes":[{ "tittle": "A Proposta ", "description": "", "image_url": "images/cartazes/img/a_proposta.jpg"}]}]}

我在JSONLint中运行它,它给出了"有效的JSON"

你可以在以下网址查看:

当我通过$.post或$.get在JSON中调用它时,我总是在回调中获得空数据.任何人都可以向我解释这是错的吗？

    <script type="text/javascript">
            $.post("http://localhost/getCinema.php", { cinemaid: 'W5'},
              function(data){
                alert(data);
                alert(data.horas[0]);
            }
            ,"json");
            alert("fim");
    </script>

Answer 1

这是因为你的字符串中有换行符.如果您查看JSON页面的源代码,则可以全部查看它们.如果删除它们,该页面将起作用.

查看:

• http://jsbin.com/umidu(清理数据 - 我所做的就是删除所有换行符)
• http://jsbin.com/ijuhi/(包含换行符的数据)

此外,您可以通过导航到帖子中的URL,查看源并复制并将其粘贴到jslint来验证您的JSON是否无效.
