Is there a way to access cross-origin iframes? got the error
[error] Blocked a frame with origin “[mydomain.com]” from accessing a cross-origin frame.
Have a look at this thread in Stack Overflow.
Quote: You need control over the domain you want to embed to remove/amend its CORS policy. If the domain has explicitely blocked Cross-Origin requests, there’s nothing you can do about it.
Katalon Studio/Recorder can do nothing for cross-origin iframe issue
Normally, scripts on different pages are allowed to access each other if and only if the pages they originate from share the same protocol, port number, and host. Above error message shows that you can’t access an < iframe > with different origin using JavaScript/jQuery, it would be a huge security flaw if you could do it.
window.postMessage() provides a controlled mechanism to securely circumvent this restriction.
