title: Get value of a checkbox?
body: <p>I have a checkbox, how do I get its value using jquery? I have this example from searching:</p>
  
  <pre><code>var checked = $('input[type=checkbox]:checked').val() != undefined;
  </code></pre>
  
  <p>but how do I specify which checkbox I'm interested in, I want to only examine a checkbox with a particular id?</p>
  
  <p>Thanks</p>
