Set HTML to an iframe

By Steven Verbeek • May 8^th, 2020

Ever wanted to set some HTML to an iframe?

You can easily do that using srcdoc attribute on an iframe if you don't care about IE 11 support.

<iframe srcdoc="<html><body>blah</body></html>"></iframe>

If you do need IE 11, support sadly you have to resort to Javascript.

document.getElementById('iframe')
    .contentWindow
    .document
    .write("<html><body>Hello world</body></html>");
