Catching exception in iframe

Question

I have configured the following iframe.

var iframe = $("<iframe style='display:none;' />");

When I change the src, the iframe loads, but I'm having a hard time catching the exception.

iframe.attr("src", url);

If I load the iframe with the 'load' function, it does catch the exception, but I need the code to be synchronous, not in ajax.

iframe.load(url, {}, function (data, status) {
   // status will be error if an exception has been thrown
});

However, if I run the following example, I cannot get the status of the call.

iframe.load(function  (param1, param2) {
   // param2 will be empty
});
