title: Javascript if (j === null) do nothing
body: <p>I'm using <a href="http://www.curvycorners.net/" rel="nofollow noreferrer">CurvyCorners</a> to make my corners curvy in IE, only thing is that when it reads the CSS it takes all the webkit properties and shows me an alert <code>curvyCorners.alert("No object with ID " + arg + " exists yet.\nCall curvyCorners(settings, obj) when it is created.");</code>.</p>
  
  <p>How can I just set this if statement to do nothing?</p>
  
  <pre><code>if (j === null)
    do nothing(); //but in real script
  </code></pre>
  
  <p>Thanks :)</p>
