is it possible that iframe resize itself without help from main window?

Question

Both main window and iframe are on the same domain, but what I want to achieve is to resize iframe to fit its contents using js only within that iframe.

I also do no

Answer 1

For same-origin content like yours, yes you can.

To borrow from Gary's answer on the above question:

In the iframe, window.parent refers to the global object of the parent document, not the document object itself. I believe you would need to use parent.document.getElementById

Try accessing the iframe using parent.document, and see if this solves your issue.
