title: jQuery equivalent of getting the context of a Canvas
body: <p>I have the following working code:</p>
  
  <pre><code>ctx = document.getElementById("canvas").getContext('2d');
  </code></pre>
  
  <p>Is there any way to re-write it to use <code>$</code>? Doing this fails:</p>
  
  <pre><code>ctx = $("#canvas").getContext('2d');
  </code></pre>
