title: jquery turning "on" and "off" event handlers
body: <p>How would I apply the "off" directive to a named handler?</p>
  
  <p>ex</p>
  
  <pre><code>var $btn = $("#theBtn");
  var namedHandler = $btn.on("click", function() {
  //do something
  //then turn off
  })
  </code></pre>
  
  <p>would I turn it off like this</p>
  
  <pre><code>$btn.off("click");
  </code></pre>
  
  <p>or could I do something else now it is stored in a variable?</p>
  
  <pre><code>namedHandler.off("click");
  </code></pre>
  
  <p>or</p>
  
  <pre><code>namedHandler.off();
  </code></pre>
  
  <p>etc.</p>
  
  <p>Any pointers much appreciated.</p>
