Is it possible that the iframe finish loading before we assign onload handler in the script?

[MulliGan81]

Having following code

<iframe id="myframe" src="..."></iframe>

<script>
document.getElementById('myframe').onload = function() {
  alert('myframe is loaded');
};
</script>

Is it possible that the iframe finish loading before we assign onload handler in the script?
