How can this be used in iframe elements injected by JS

[chaoming]

I am trying to use document.createElement('iframe') and setAttribute('is','x-frame-bypass') to create a dynamic iframe. But not sure how to make it work on the dynamic injected iframes.

The simplest way is: document.write('<iframe is="x-frame-bypass" src="..."></iframe>') or element.innerHTML = '<iframe is="x-frame-bypass" src="..."></iframe>'

const ifrm = document.createElement('iframe'); ifrm.setAttribute('is', 'x-frame-bypass'); ifrm.setAttribute('width', '500px'); ifrm.setAttribute('height', '350px'); ifrm.setAttribute('src', 'your HTML URL');

Add function to onload. Assuming you've already reference Jquery.

<iframe is="x-frame-bypass" id="iframe" onload="oniFrameLoad(this)" src="https://..." width="100%" height="100%" frameBorder="0"></iframe>

<script>
function oniFrameLoad() {
	var scriptTag = "....";
	scriptTag += "}";

	console.log(scriptTag);
	//inject content into iframe
	$('#iframe').contents().find('body').append($('<script>').html(scriptTag))
};
</script>
