php - jQuery JSON 和 PHP 关联数组数组问题

Question

您好，我想知道是否有人可以帮助我？

我有以下代码。它从 php 文件检索 JSON 数据。 Json 的格式如下:

{"Title":"rose","Price":1.25,"Number":15},{"Title":"daisy","Price":0.75,"Number":25},{"Title":"orchid","Price":1.15,"Number":7} 

此 JSON 是使用以下 php 代码创建的:

$shop = array();
$shop = array( array( Title => "rose", 
                  Price => 1.25,
                  Number => 15 
                ),
           array( Title => "daisy", 
                  Price => 0.75,
                  Number => 25,
                ),
           array( Title => "orchid", 
                  Price => 1.15,
                  Number => 7 
                )
         );

 echo json_encode($shop);

每当我尝试使用 obj.Title 访问数据时，我都会收到一条未定义的消息。

 $.ajax({
        type: "GET",
        url: "data.php",
        success: jsonDo
    });

    //JSON DATA = {"Title":"rose","Price":1.25,"Number":15},{"Title":"daisy","Price":0.75,"Number":25},{"Title":"orchid","Price":1.15,"Number":7}

    function jsonDo(data) {

        var obj = jQuery.parseJSON(data);

        alert(obj.Title)

    }

我想知道如何访问 JSON 中的键并显示数据？

感谢一百万。

Answer 1

var obj = jQuery.parseJSON('{"Title":"rose","Price":"1.25","Number":"15"}');

alert(obj.Title);

这项工作。检查代码中的差异。

好吧，这更正确:

var obj = [
    {"Title":"rose","Price":"1.25","Number":"15"},
    {"Title":"daisy","Price":"0.75","Number":"25"},
    {"Title":"orchid","Price":"1.15","Number":"7"}
    ];


 alert(obj[1].Title);
