Stopping a iframe from loading a page using javascript

Question

Is there a way in javascript of stopping an iframe in the middle of loading a page? The reason I need to do this is I have a background iframe streaming data from a web serv

If you only have a reference to the element, you need to use .contentX to get the document/window to run the accepted answer.
Checking that the iframe actually has a document is also necessary for dynamically added iframe elements.

function stopIframe(element) {
    var doc = element.contentDocument;
    //iframes wont have a document if they aren't loading/loaded
    //check so JS wont throw
    if (!doc)
        return;

    //try for modern browsers
    if (doc.defaultView.stop)
        doc.defaultView.stop();
    //fallback for IE
    else
        doc.execCommand('Stop');
}
