Safari Doesn't Call Iframe Onload When Src Is Not Valid Site

For the following iframe, Safari never calls the onload function and doesn't display anything in the iframe. All other browsers I've tested do call onload and display a default err

Solution 1:

I just the other day stumbled upon this post with a workaround for the missing load event in Safari. The post is from 2011 but seems to be still valid.

The solution proposed there for Safari is to check for the readyState event on the iframe's document like so:

<iframeid="ifra"src="http://www.asdkjhjhkjhkjhjhjhfhkjhsdflkjahdsjfhasf.com"onload="alert('iframe loaded');"></iframe><script>var iframe = document.getElementById('ifra'),
        doc = iframe.contentDocument || iframe.contentWindow;
    if (doc.document) doc = doc.document;
    var _timer = setInterval(function() {
        if (doc.readyState == 'complete') {
            clearInterval(_timer);
            alert('iframe ready');
        }
    }, 1000);
</script>

As per Mozilla's documentation on contentDocument, you wouldn't need to include the workaround with the contentWindow when running this script only in Safari, but I kept it in here in case you want to use it across browsers.
