An example Analysis of the order of data returned by ajax requests

Editor to share with you the ajax request return data order of the example analysis, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to know it!

The details are as follows:

After ajax requests a url,php backend for processing, the array is in the following format:

A = array ('- 1percent = > 10,'- 3' = > 2,'0' = >'5','- 2' = > 4)

Then use the asort function of php to sort the array in ascending order by value, as follows:

$a = array ('- 3'= > 2,'- 2'= > 4) 0' = > 5cm,'- 1century = > 10)

The return value received by the front-end ajax is still unordered.

The possible reason is that because the key value is a character exchange, js reorders the data.

The treatment plan is as follows:

$I = 0 tmp foreach ($data as $k = > $v) {$tmp [$I] ['data'] = $v; $tmp [$I] [' key'] = $k; $ifold foreach;}

At this point, the data is as follows:

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

Ajax receiving and processing, the data is correct.
