转换解析的JSON来JavaScript数组

问题描述：

$array1 = array("fruits" => "banana","vegetables" => "tomatos"); 
$array2 = array("name" => "Jack","Age" => "32"); 

$array3 = array($array1, $array2); 

echo json_encode($array3);

JavaScript代码包括jquery的：

var json_data = $.ajax({ 
       type: 'POST', 
       url: 'scripts/myfile.php', 
       data: { action: 'myaction' }, 
       dataType: 'json', 
       cache: false, 
       success: function(result) { 

       } 
      }); 
      console.log(json_data);

这是浏览器的控制台的json_data内容：

"{"HUM":[{"label":"2014-10-16 17:08:55","y":"58"},{"label":"2014-10-15 08:16:55","y":"56"},{"label":"2014-10-15 08:16:50","y":"56"},{"label":"2014-10-15 08:16:45","y":"56"},{"label":"2014-10-15 08:16:40","y":"56"},{"label":"2014-10-15 08:16:35","y":"56"},{"label":"2014-10-15 08:16:30","y":"56"},{"label":"2014-10-15 08:16:25","y":"56"},{"label":"2014-10-15 08:16:20","y":"56"},{"label":"2014-10-15 08:16:15","y":"56"},

现在我想将其转换为数组，然后将它分离到数组HUM - TEMP - HUM2 - TEMP2

VAR OBJ = JSON.parse（json_data）; – Jose 2014-10-17 15:13:49

您的阵列未被终止。 'JSON.parse（）'会抛出语法错误。 – Joe 2014-10-17 15:22:45

答

您需要使用parseJson方法从该json创建对象。

result = $.parseJson(result);

现在你将有一个物体里面所有的数组：

console.log(result['HUM']); 
console.log(result['TEMP']); 
// etc

是不是只是JSON.parse（字符串）？这是jQuery的实现，它不是像这样的js原生的。否则，它会工作，但。 – somethinghere 2014-10-17 15:15:32

var json_data = $ .ajax（{....}）;该变量默认情况下jquery中的parsejson（结果）我的问题是如何将该对象转换为数组 – Souf 2014-10-17 15:17:22

在控制台对象{HUM：Array [50]，TEMP：Array [50]，HUM2：Array [50]，TEMP2 ：Array [50]} – Souf 2014-10-17 15:20:12

答

你需要这个方法

JSON.parse(json_data);

已经试过了，它给出错误 – Souf 2014-10-17 15:21:15

答

你可以用它获取传递给你的AJAX调用的的result变量success功能：

success: function(result) { 
    // result here is your JSON data which has already been parsed 
}

您可以使用点或括号记号访问单独的阵列：

var HUM = result.HUM; 
// or 
var HUM = result["HUM"];

他们已经指定'dataType：'json''，这意味着jQuery无论如何都会将服务器响应解析为JSON。再次调用'JSON.parse'会很糟糕。 – 2014-10-17 15:16:57

@AnthonyGrist啊，我放置了错误的变量。感谢那！ – 2014-10-17 15:18:13

我想你已经误解了我想说的话。没有任何理由根据任何变量调用'JSON.parse（）'（'json_data'甚至不是JSON数据，它是一个jQuery Deferred）。响应将已经是一个对象，他们只需要使用'result'作为对象，并访问'result.HUM'等。 – 2014-10-17 15:21:05
