Access parent properties (iframe)

help
1

My meteor app is inside iframe (<iframe src="http://myApp.meteor.com"></iframe>), and I want to access parent property. It’s possible?

My page:

<!DOCTYPE html>
<html>
<body>
   <div id="myDiv">old text</div>
   <iframe src="http://myApp.meteor.com"></iframe>
</body>
</html>

Meteor app client code:

Template.myApp.rendered = function () {
    parent.document.getElementById('#myDiv').innerHTML = 'new text';
};

Error:

Exception from Tracker afterFlush function: Permission denied to access property “document”
