title: jQuery: Posting an array quirk with square brackets
body: <p>I'm using the following code to make a post.</p>
  
  <pre><code>var checked = ["2231","2432"];
  
  jQuery.ajax({
              type: 'post',
              url: statusUrl,
              data: {"entries":checked},
  ...
  </code></pre>
  
  <p>However, when it actually posts, Post Data on server side and inspection in developer tools is always</p>
  
  <pre><code> {entries[]: 2342 etc}
  </code></pre>
  
  <p>Why are the square brackets appearing? How can I get rid of it?</p>
