I use embedded videos on my website and want to automate a test that they all render properly. I could get the video's title and tried this in a browser's JavaScript:
var iframe = document.getElementById("iframe");
iframe.contentWindow.document;
and got a SecurityError
similar to SecurityError: Blocked a frame with origin from accessing a cross-origin frame . I don't want to disable that security feature in my browser.
For reference, the website with the embedded video is https://emotionathletes.org/day1.
How can I get the title of an embedded video to make sure it displays on a website?
