How to get notified about IFRAME appended dynamically and loaded?
I need to add an ability to a Firefox extension to handle cases when IFRAME elements are being added dynamically. Is there a way to get notified when IFRAME document is loaded in such a case?
For example:
<html>
<head>
<title>iframe test</title>
<script type="text/javascript">
function addIFrame() {
var ifrm = document.createElement("iframe");
ifrm.setAttribute("src", " http://www.google.com/");
document.body.appendChild(ifrm);
}
setTimeout('addIFrame()', 3000);
</script>
</head>
<body>
<p>A new <i开发者_运维问答frame> will be added in 3 seconds:</p>
</body>
</html>
You can set a capturing load listener on the tabbrowser and then check that the event's target is an <html:iframe>.
