 <span id="data"></span>
 <iframe name="dd" src="http://otherdomain.com/innerpage.html" style="width:600px;height:500px;"></iframe>
</div>
</body>
</html>

innerpage.html(on another domain)

code:

<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
 function SendDataToParent(){
  var dataId = parent.document.getElementById("data"),
   data = document.getElementById("iframeData").value;
   dataId.innerHTML ="<input type='hidden' value='"+data+"' name='dataFromChildIframe'/>";

For security reasons, it is completely impossible to pages in two different domains to communicate on the client in current browsers.

As a workaround, you can use JSONP in both pages.
