title: Safari + Jquery + Replace
body: <p>Couldn't find any answers to this question:</p>
  
  <p>How come this works everywhere except in Safari?</p>
  
  <pre><code>var img = $(this).css('background-image');
  img = img.replace('url("', '').replace('")', '');
  </code></pre>
  
  <p>Thank you in advance.</p>
