Question

嗨我有这样的PHP代码：

$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：

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

                }
            });
           console.log(json_data );

这是浏览器控制台中的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"},

现在我想将它转换为数组然后将其转换为数组HUM - TEMP - HUM2 - TEMP2

Answer 1

您可以使用传递给AJAX调用result函数的success变量：

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

您可以使用点或括号表示法访问各个数组：

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

Answer 2

您需要使用parseJson方法从该json创建对象。

result = $.parseJson( result );

现在，您将在该对象中包含所有数组：

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

Answer 3

你需要这个方法

JSON.parse(json_data);

将解析的json转换为javascript数组
