如何在Javascript中将json编码的PHP数组转换为数组？

Question

我从PHP文件中使用AJAX获取JSON编码数组,但在JavaScript中我需要将其用作数组,如何在Javascript中创建数组？

我的AJAX调用PHP文件:

  $.ajax({
    type:"POST",
    url:"ajaxfetch.php",
    success:function(result){
            alert(result);
             }
    });

ARRAY在PHP文件中创建:

Array
(
    [0] => Array
        (
            [id] => 4
            [deviceID] => xyz123
            [latitude] =>  -33.80010128657071
            [longitude] => 151.28747820854187
            [altitude] => 34.78788787
            [createdDate] => 2013-08-15 23:00:00
            [delete] => 0
        )

    [1] => Array
        (
            [id] => 5
            [deviceID] => jdkfhjskh344
            [latitude] => -33.950198
            [longitude] => 151.259302
            [altitude] => 76.44455
            [createdDate] => 2013-08-15 21:50:42
            [delete] => 0
        )

    [2] => Array
        (
            [id] => 1
            [deviceID] => abc223
            [latitude] => -33.890542
            [longitude] => 151.274856
            [altitude] => 21.4454455
            [createdDate] => 2013-08-15 20:00:00
            [delete] => 0
        )

)

我json用PHP编码了这个数组,但是AJAX检索它并以字符串形式输出.

上面的ARRAY json编码如下:

$data = array();
$data = $locate_obj->getAllDeviceLocation();


echo json_encode($data);

输出json_encode

[{"id":"4","deviceID":"xyz123","latitude":" -33.80010128657071","longitude":"151.28747820854187","altitude":"34.78788787","createdDate":"2013-08-15 23:00:00","delete":"0"},{"id":"5","deviceID":"jdkfhjskh344","latitude":"-33.950198","longitude":"151.259302","altitude":"76.44455","createdDate":"2013-08-15 21:50:42","delete":"0"},{"id":"1","deviceID":"abc223","latitude":"-33.890542","longitude":"151.274856","altitude":"21.4454455","createdDate":"2013-08-15 20:00:00","delete":"0"}]

我正在寻找可以在Javascript中使用我在ajax响应中收到的输出创建数组的方式,这样我就可以得到一个格式数组:

var locations = [
      ['Bondi Beach', -33.890542, 151.274856, 4],
      ['Coogee Beach', -33.923036, 151.259052, 5],
      ['Cronulla Beach', -34.028249, 151.157507, 3],
      ['Manly Beach', -33.80010128657071, 151.28747820854187, 2],
      ['Maroubra Beach', -33.950198, 151.259302, 1]
    ];

这个问题有三个解决方案:

• JSON.parse显式调用并将响应文本传递给它.返回值将是JavaScript数据类型.

• dataType: 'json'在$.ajax调用中设置选项,以便jQuery为您解析JSON.

• 在PHP中为JSON设置正确的响应头.jQuery将检测标头并自动解析JSON.

如果要在客户端修改结构,请查看Access/process(嵌套)对象,数组或JSON.
