There are already several questions on this topic, but none have really been answered yet.
I really want to disable cross site origin security to access an iframe element and control it via javascript.
I realize that this is a security feature, but then you have to be able to disable it, especially if you explicitly want it in a certain context.
I know it’s possible because you can select the iframe via the hover cursor in the dev tools of any browser and then all javascript commands work directly in the iframe.
However, if I try this without using the cursor select function (directly with Javascript), I keep getting the error:
Command:
var iframe = document.querySelector('iframe');
iframe.contentWindow.contentDocument;
Error:
Uncaught SecurityError: Failed to read a named property 'contentDocument' from 'Window': Blocked a frame with origin “https://example.com” from accessing a cross-origin frame
How could I get around this?
Are there any browsers that allow me to bypass these functions?
