title: How to Check if an iFrame Has a Value In It
body: <p>I have the following iframe within a parent window:</p>
  
  <pre><code>&lt;iframe
     name="sg_iframe" 
     id="sg_iframe" 
     src="www.myurl.com"
     align="left"
     height="150px" 
     width="750"
     frameborder="0" 
     marginheight="0" 
     marginwidth="0"
     overflow="auto"&gt;
  &lt;/iframe&gt;
  </code></pre>
  
  <p>Now within www.myurl.com, let’s say I have a report that display 3 fields based on some criteria.</p>
  
  <p>So based on this, how can I check from the parent form whether the iframe described above is empty of data, i.e. no report data listed or actually does have data using jquery/javascript?</p>
  
  <p>Basically just need to know if the report within the iframe has 0 rows or 1 or more rows.</p>
  
  <p>Thanks.</p>
