Javascript jQuery获取JSON访问结果

我使用以下命令提取json数组：

$.get('URL')
.always(function(data) {
    console.log(data);

直接访问URL时会返回以下信息：

        "ipaddr": "192.168.37.10.",

                        var g = m.isFunction(a[b]) && a[b];
                        e[f[1]](function() {
                            var a = g && g.apply(this, arguments);
                            a && m.isFunction(a.promise) ? a.promise().done(c.resolve).fail(c.reject).progress(c.notify) : c[f[0] + "With"](this === d ? c.promise() : this, g ? [a] : arguments)
                        })
                    }), a = null
                }).promise()
            }
            __proto__: Object

我为上述格式表示歉意。我不知道如何正确地格式化它

无论如何，这其中最重要的部分是responseText。responseText相当于直接访问URL时返回的数据。我需要能够从中提取特定元素（例如，今天的攻击）

简单地说：

data.responseText.attacks_today
OR
data['responseText']['attacks_today']

不工作。我还尝试了各种循环方法，但它们都会给我相同类型的错误：

var arr = data.responseText;                                    
$.each( arr, function( index, entry ) {   

结果：

Uncaught TypeError: Cannot use 'in' operator to search for '1700' in ...

必须有一些简单的方法来访问json元素，除非我弄错了，但我只是没有看到它

我使用的是jQuery版本1.11.0

谢谢。

您的Ajax失败了。文档说，如果请求成功，第一个参数将是xhr对象或数据对象

始终（函数（数据| jqXHR、文本状态、jqXHR |错误抛出）{ });

完整回调选项的另一个构造是 .always（）方法替换不推荐使用的.complete（）方法

为了响应成功的请求，函数的参数是 与.done（）相同：data、textStatus和jqXHR对象。对于 失败的请求参数与.fail（）的参数相同： jqXHR对象、textStatus和error抛出。请参阅deferred.always（） 有关实施细节

---

您看到的对象是XHR对象，因为请求失败。如果您想确保在找出请求失败的原因后总是能得到结果，请使用.done（data）。

Matt：在我测试的每种情况下（无论是直接访问数组元素，还是在json数组上循环），get和getJSON有同样的问题。尝试

。然后

而不是

。始终

。如果将JSON响应复制到中，它是否有效？尝试解析从ajax接收的数据，例如：data=JSON。解析（数据），这样您将得到一个对象而不是字符串，讨论JSON中的数据类型字段标签必须在

中

。所以

0:{“ID”：7611…

无效。它应该是

“0”：{“ID”：7611…

Paul，是的，几分钟前Mac为我指明了验证JSON的方向后，我才意识到这一点。总是有效的，但是。完成了没有。失败了，所以它返回了一些不好的数据。我将深入研究数据不好的原因。谢谢。确保你在响应头中返回了application/JSON。这是一件事如果您传递给请求的URL是正确的，并且您在浏览器中看到了良好的响应，我可以认为这会破坏它。响应头是正确的。问题是，在代码中的其他地方，完全与我的工作空间分离，一些额外的数据被传递到json返回中。抑制这些额外的内容可以修复d JSON验证，解决了这个问题。谢谢！
