我的问题是,JavaScript或jQueryAPI没有解析这个JSON。我包括下面的代码和JSON输出所在的URL。

此JSON在JavaScript中被解析为nothing:

//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 prÃncipe Misterioso ", "description": "", "image_url": "images/cartazes/img/harry_potter_e_o_principe_misterioso.jpg"}]},{"hora": "16:30","filmes":[{ "tittle": "Harry Potter e o prÃncipe Misterioso ", "description": "", "image_url": "images/cartazes/img/harry_potter_e_o_principe_misterioso.jpg"}]},{"hora": "20:30","filmes":[{ "tittle": "Harry Potter e o prÃncipe 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 prÃncipe Misterioso ", "description": "", "image_url": "images/cartazes/img/harry_potter_e_o_principe_misterioso.jpg"}]},{"hora": "13:30","filmes":[{ "tittle": "Harry Potter e o prÃncipe Misterioso ", "description": "", "image_url": "images/cartazes/img/harry_potter_e_o_principe_misterioso.jpg"}]},{"hora": "17:10","filmes":[{ "tittle": "Harry Potter e o prÃncipe 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"}]}]}

当我通过 $.post 或 $.get 在JSON中,我总是在回调中获取空数据。谁能给我解释一下这是怎么回事吗?

注:

这不是因为“同一原产地政策”)

              function(data){
                alert(data);
                alert(data.horas[0]);

            ,"json");

这是因为你的弦上有断线。如果您查看JSON页面的源代码,您可以看到所有这些内容。如果删除它们,页面将正常工作。

退房:

http://jsbin.com/ijuhi/ (其中包含包含换行符的数据)

此外,您还可以通过导航到帖子中的URL、查看源代码并将其复制粘贴到jslint中来验证JSON是否无效。

您是否在php脚本中正确地编码了它?

警报(数据)似乎返回一个对象,因为它是一个有效字符串。警报(data.horas[0]。hora为您提供未定义的消息,因为该对象未被解释为JSON(例如,一组hora对象,每个对象都具有hora属性)。

在php中尝试以下操作:

<?php echo json_encode(... your array of hora objects here ...); ?>
