You can capture the onload event of an iframe. Target your form to the iframe and listen for the onload. You will not be able to access the contents of the iframe though, just the event.

Try something like this:

...

script block:

var loadComplete = 0
function loaded() {
    //avoid first onload
    if(loadComplete==0) {
        loadComplete=1
        return()
    }
    alert("form has loaded")
}
