title: jQuery - If checkbox value="test" uncheck
body: <p>I have been trying to use jQuery to uncheck the checkbox if value is = to a variable for instance "test"
  Example:</p>
  
  <p><code>&lt;input type="checkbox" name="cbname" value="test" checked="checked" /&gt;</code></p>
  
  <p>Since this one has a value of test i would like it to be unticked, how could i do this?</p>
  
  <p>thanks</p>
