Following DrJokepu's and David Murdoch idea I implemented a more complete version. It requires jQuery on both the parent and iframe and the iframe to be in your control.

iframe code:

var iframe = window.frameElement;

if (iframe){
    iframe.contentDocument = document;//normalization: some browsers don't set the contentDocument, only the contentWindow

    var parent = window.parent;
    $(parent.document).ready(function(){//wait for parent to make sure it has jQuery ready
        var parent$ = parent.jQuery;

        parent$(iframe).trigger("iframeloading");

        $(function(){
            parent$(iframe).trigger("iframeready");
        });

        $(window).load(function(){//kind of unnecessary, but here for completion
            parent$(iframe).trigger("iframeloaded");
        });

        $(window).unload(function(e){//not possible to prevent default
            parent$(iframe).trigger("iframeunloaded");
        });

        $(window).on("beforeunload",function(){
            parent$(iframe).trigger("iframebeforeunload");
        });
    });
}

parent test code:

$(function(){
    $("iframe").on("iframeloading iframeready iframeloaded iframebeforeunload iframeunloaded", function(e){
        console.log(e.type);
    });
});
