title: Checkbox boolean
body: <p>I have the following checkbox:</p>
  
  <pre><code>&lt;input type="checkbox" id="blacklist" value="&lt;c:out value="${param.blacklist}" /&gt;" name="blacklist" style="width: 300px; padding-left: 5px"/&gt;           
  </code></pre>
  
  <p>param.blacklist is a boolean, it should return false if checbox is not selected and true if checkbox is selected.</p>
  
  <p>Since i'm not so good on html / javascript someone can give me a tip, pls?</p>
