title: append date to iFrame src property with javascript
body: <p>I'm passing a disclosure page through an iframe on an html page:</p>
  
  <pre><code>&lt;iframe src="../disclosures/Pass_CO_GRN.html" name="disclose" width="790" marginwidth="0" height="400"  marginheight="0" scrolling="Auto" id="disclose" frameborder="0" &gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>I would like to add attach a datetime method to the src attribute to be sure the asset being passed (Pass_CO_GRN.html) does not cache in the client browser. The way I do this with the linked .js file (which I also don't want cached) is:</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
  document.write('&lt;script language="JavaScript" src="linksHLS4.js?'+(new Date).getTime()+'"&gt;&lt;'+'/script&gt;');
  </code></pre>
  
  <p></p>
  
  <p>and this works perfectly. I'm just not sure how to adapt it (if it CAN be adapted) to the iframe tag. anyone know?</p>
