This time I will bring you the order of data returned by ajax request operation. What are the precautions for the order of data returned by ajax request operation? The following is a practical case, let's take a look.

ajax requests a url, and after PHP backend processing, the

array is in the following format: 

$a = array( '-1'=> 10 ,'-3' => 2, '0' => '5' ,'-2' => 4);
Copy after login

Then use PHP's asort function to sort the array in ascending order by value, As follows: 

$a = array('-3' => 2, '-2' => 4，'0' => '5', '-1'=> 10  );
Copy after login

The return value received by the front-end ajax is still out of order.

The possible reason is: because the key value is character replacement, js reorders the data

The processing plan is as follows: 

$i = 0;
foreach ($data as $k => $v) {
   $tmp[$i]['data'] = $v;
   $tmp[$i]['key'] = $k;
   $i++;
}
Copy after login

The data at this time is as follows:

{
  "rows": [
    {
      "data": "2",
      "key": 0-3
    },
    {
      "data": "4",
      "key": -12
    },
    {
      "data": "5",
      "key": 0
    },
    {
      "data": "10",
      "key": -1
    }
  ]
}
Copy after login

ajax reception and processing, the data is correct.
