title: Javascript: refresh IFrame browser specific
body: <p>i need a solution for refreshing an iframe which works for different browsers.
  <br />can you confirm, that the code i found on the internet is correct or give me the correct javascript?</p>
  
  <p>IE 7
    <code>window.document.getElementById('iframeId').contentWindow.location.reload(true);</code></p>
  
  <p>IE 8
    <code>window.document.getElementById('iframeId').contentWindow.location.reload(true);</code></p>
  
  <p>IE 9
    <code>window.document.getElementById('iframeId').contentWindow.location.reload(true);</code></p>
  
  <p>Firefox 12-17 <br />
    <code>window.document.getElementById('iframeId').src = window.document.getElementById('iframeId').src;</code></p>
  
  <p>Chrome &lt; 19<br />
    <code>document.getElementById('iframeId').contentWindow.location.reload();</code><br /></p>
  
  <p>Chrome now <br />
  ???</p>
  
  <p>Safari and Opera would be nice, but the above are important. the iframe may be in a different domain.</p>
  
  <p>Many thanks in advance!</p>
