title: How to read cross- domain iframe content?
body: <p>I am embedding an iframe which has src ="" from another domain.</p>
  
  <p>For example, my page is www.abc.com/Default.aspx, and the iframe </p>
  
  <pre><code>&lt;iframe id="myFrame" src="www.xyz.com"&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>All that I want to do is when I click on submit button of iframe from
  then I should display an alert.</p>
  
  <pre><code>&lt;script&gt;
      $(document).ready(function(){
         $("button[type=submit]").click(function () {
             alert();
         });
  
      });
  &lt;/script&gt;
  </code></pre>
