title: How to get a browser to spot this javascript/jquery syntax error?
body: <p>I had a subtle typo in a javascript I was testing - a double-apostrophe instead of a single. Can you spot it? </p>
  
  <pre><code>$('#visa, #mastercard').click(function() {
      $('#creditCard input').attr('disabled', false).css('backgroundColor",''); 
      $('#creditCard label').css('color','');
  }); 
  </code></pre>
  
  <p>My question is - is there a way to have this error flagged in the browser? When I look at the console in both Chrome and Firefox (firebug), nothing shows up. </p>
