is there any way how to access from iframe to parrent page (and change parrent page)?

<body>
   <iframe src="frame1.html" name="frame1" height="100%"></iframe>
   <div id="test1"></div>
</body>

In frame1.html is <a href=..> and I want to add text "<h1>clicked</h1>" into <div id="test1"></div>, when the <a href..> was clicked.

Thanks.

If your child page (frame1.html) is located at the same domain as the parent page, You can write a code like below in the child window :

 $('#test1', parent.document).html('<h1>clicked</h1>');

The second parameter provides the context in which to search the element matched by the first parameter. The Document is here:http://api.jquery.com/jQuery/#jQuery-selector-context

 jQuery( selector [, context ] )

So, your code (frame1.html) could go like this:

 <a href="..." 
  onclick="$('#test1', parent.document).html('<h1>clicked</h1>');">click me</a>

Hope this helps.
