Answer
to add content to iframe, you should pass by src attribute, here is an example.
JavaScript

1
var iframe = document.createElement('iframe'); 2
var html = '<body>Foo</body>'; 3
iframe.src = 'data:text/html;charset=utf-8,' + encodeURI(html); document.body.appendChild(iframe);4
if your content is url, you put it directly into src,like this

iframe.src="https://www.w3schools.com"2
