Question

我有一个数组的Php数组，json编码为

 [{"TASK_ID":"79","USER_ID":"cool12",
   "LATITUDE":"32.702550412612524",
   "LONGITUDE":"74.85893413424492",
   "STARTED_ON":"2016-06-07 14:57:05",
   "STOPED_ON":"2016-06-07 14:57:05",
   "DEVICE_ID":null,"DEVICE_NAME":null,
   "DEVICE_TYPE":null,"PATH_ENDED":"0"},  
   {"TASK_ID":"80",
    "USER_ID":"cool12", 
   "LATITUDE":"32.70255831226375",
  "LONGITUDE":"74.85894754529",
  "STARTED_ON":"2016-06-07 14:57:06",
  "STOPED_ON":"2016-06-07 14:57:06",
 "DEVICE_ID":null,
  "DEVICE_NAME":null,
  "DEVICE_TYPE":null,
 "PATH_ENDED”:”0”}]


var ar = <?php echo json_encode($resultArray) ?>;

给出了这个结果

Array [ Object, Object, Object, Object, Object, Object, Object, Object, Object, Object, 25 more… ]

如何解析此数组以获取值

Answer 1

json_encode()是一个从PHP数组中创建JSON字符串的函数。

这里要注意的重要一点是PHP array有点类似于 Javascript Object包含key和value对。

因此，在javascript中获取变量ar之后，您只需要JSON.parse(ar)，然后通过以下任何循环（或任何其他自定义函数）遍历变量：< / p>

forEach
for in循环
for of循环
