as long as you are in the same domain (pop-up and opener), there should not be a problem...

I put this on my iframe source to a button that contains the iframe tag and I get an error

<body onLoad="window.opener.document.getElementById('backButton').onclick = 'google.com'">

ERROR: window.opener.document is null or not an object

var myWin = null;
function clickIt () {
if (myWin && !myWin.closed) {
alert("Window is already open");
} else {
myWin = window.open('window.html', '');
}
}
</script>

"opener" is for pop-ups.. not iframes...

this should work in an iframe:

<script>
function testf2() {
  alert("this is test ");
}

alert( "test: " + parent.document.getElementById('testLink').onclick );
                  parent.document.getElementById('testLink').onclick = testf2;
alert( "test: " + parent.document.getElementById('testLink').onclick );
</script>
