jQuery & JSON – Make JSON POST request using jQuery.post()

We can also make JSON POST request using the jQuery.post() function. If you want to use GET request. please refer to the previous post.
jQuery & JSON – Make JSON GET request using jQuery.getJSON()

 
Update @ 2011-10-13: This example does not work for Cross Domain POST request since the Current jQuery version(1.6.4) does not allow a Cross Domain POST request. For more information, you can refer to Mark Needham – jQuery: $.post, ‘jsonp’ and cross-domain requests

So if you want to make a Cross Domain GET request. Take a look on the following post.
jQuery & JSON – Make Cross Domain Request Using jQuery.getJSON() with JSONP

 
Here is the new server.php

<?php
  $arr1 = array('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);
  $arr2 = array('a'=>5,'b'=>4,'c'=>3,'d'=>2,'e'=>1);
  
  if ($_SERVER['REQUEST_METHOD'] == 'GET') {
    // GET request received
    if ($_GET['param1'] == 'ykyuen' && $_GET['param2'] == 'eureka') {
      print json_encode($arr1);
    } else {
      print json_encode($arr2);
    }
  } else if($_SERVER['REQUEST_METHOD'] == 'POST') {
    // POST request received
    $arr3 = array('1st' => $_POST['param1'], '2nd' => $_POST['param2']);
    print json_encode($arr3);
  }
?>

 

json-post.php

<html>
  <head>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
  </head>
  <body>
    <script>
      $.post('http://localhost/json-request/server.php',
        {
          param1: "ykyuen",
          param2: "eureka"
        },
        success,
        "json"
      );
      
      function success(data) {
        $.each(data, function(key, val) {
          $("body").append(key + " : " + val + "<br/>");
        });
      }
    </script>
  </body>
</html>
