title: Append query string to iframe source
body: <p>I've got a page with several iframes that are added by the end user via a cms. I need to append a query string (exactly the same to all iframes) to the end of the iframe source and am stuck on how to proceed.</p>
  
  <p>My current code is here where .frame-wrap is a container around all iframes:</p>
  
  <pre><code>$(document).ready(function() {
  
      var hideLinkHeader = '?hideLink=true&amp;hideHeader=true';
      var url = cannot figure out how to set this for each iframe
  
      $('.frame-wrap').find('iframe').attr('src', url + hideLinkHeader);
  
  });
  </code></pre>
  
  <p>Any help is greatly appreciated.</p>
