可能重复:
循环通过Json对象

我有一个PHP函数,data.php它从外部服务器URL获取JSON数据,如:

<?php
$url = "https://dev.externalserver.net/directory";
$content = file_get_contents($url);
echo json_encode($content);
?>

检索到的JSON数组如下所示:

[ 
   { "name": "Not configured", 
     "mac_address": "1111c11c1111", 
     "online": "false", 
     "rate": "Not configured" },

   { "name": "Not configured", 
     "mac_address": "0000c00c0000", 
     "online": "false", 
     "rate": "Not configured" } 
]

我现在正在尝试编写一个对该PHP函数的AJAX调用,遍历JSON数组,并以非JSON格式在浏览器中显示它.我的AJAX代码如下所示:

$.ajax({ url: 'data.php',
         type: 'POST',
         dataType: 'json',
         success: function(output) {            
            $.each(output, function() { 
                $.each(this, function(key, value){
                    alert(key + " --> " + value); 
                });
            });
                                   }
});

我的问题是,代码当前显示的警告框,显示像这样的阵列内的单个字符:0 --> [,0 --> ,0 --> …
