title: jQuery post array
body: <p>Am wondering how to post an array using $.ajax. My array is something like this:</p>
  
  <pre><code>var a = new Array();
  a['test'] = 1;
  a['test2'] = 2;
  and so on...
  </code></pre>
  
  <p>I tried:</p>
  
  <pre><code>$.ajax({
    url: baseUrl+"chat.php",
    data: { vars: a},
    type: 'post',
    success: function(data) {
  alert(data);
  }});
  </code></pre>
  
  <p>Any suggestions?</p>
