I think it will be something like this:
var script=iframe.createElement('script');
script=iframe.standardCreateElement('script');
script.setAttribute('src','http://localhost/jquery-1.3.2.js');
script.setAttribute('type','text/javascript');
iframe.lastChild.firstChild.appendChild(script);
Note this can be done just if the iframe and the holder page are in the same domain, or if you calling this from a bookmarklet or a browser extension/plugin.

This should work... Maybe you are trying to create something like this:
<body onload="initialize()">
<script language="JavaScript">
function initialize() {
var testFrame =
document.createElement("IFRAME");
testFrame.id = "testFrame";
testFrame.name = 'hehe';
testFrame.src = "http://www.seekload.tk";
testFrame.style.border='20px';
testFrame.style.width='900px';
testFrame.style.height='300px';
testFrame.style.frameBorder = 10;
testFrame.style.overflow = "hidden";
testFrame.style.align = "left";
testFrame.style.display = "block";
testFrame.style.fontSize = "10px";
document.body.appendChild(testFrame);
}
</script>
PS: You made some mistakes in your coding try the above instead.

No, you cannot insert code into a document from another domain. This is a security measure enforced by the browser to prevent cross-site scripting (XSS) and phishing attacks.
