Ho trovato una discussione simile, Uncaught SecurityError: Failed to read the 'contentDocument' property from 'HTMLIFram.

This issue fired when you try to call ajax to another domain, please check this article for more info about Same origin policy

Mozilla's Same Origin article

For fix this, you will need to add this code

document.domain = 'yourdomain.com' 

Dall'articolo stesso:

A page may change its own origin with some limitations. A script can set the value of document.domain to a subset of the current domain. If it does so, the shorter domain is used for subsequent origin checks. For example, assume a script in the document at http://store.company.com/dir/other.html executes the following statement:

document.domain = "company.com"; 

After that statement executes, the page would pass the origin check with http://company.com/dir/page.html . However, by the same reasoning, company.com could not set document.domain to othercompany.com.

The port number is kept separately by the browser. Any call to the setter, including document.domain = document.domain causes the port number to be overwritten with null. Therefore one cannot make company.com:8080 talk to company.com by only setting document.domain = "company.com" in the first. It has to be set in both so that port numbers are both null.

Answer 2

La mia soluzione ricostruisce l'IFRA me e utilizzabile in angolare. Quando costruiamo un iframe, è richiesto il controllo della sicurezza dell'origine per modificare il contenuto iframe. Questa soluzione ci consente di ricreare più volte i contenuti iframe.

HTML

<div id="iframecontainer"></div> 

JS

var content = "<h1>Content inside Iframe</h1>"; //desired content of iframe 
var iframecontainer = document.getElementById("iframecontainer"); 
iframecontainer.innerHTML ='<iframe id="threedsframe" width="%90" height="400px"></iframe>'; 
var iframe = iframecontainer.childNodes[0]; 
let doc = iframe.contentDocument || iframe.contentWindow; 
doc.open(); 
doc.write(content); 
doc.close();
