Why is my iframe throwing an \'X-Frame-Options\' error, and how can I fix it?

Setting 'X-Frame-Options' on an iframe

When creating an iframe with JavaScript, you may encounter an error indicating that 'X-Frame-Options' is set to 'SAMEORIGIN' on the requested resource. This means that the domain hosting the resource (such as 'https://www.google.com.ua') has prohibited loading the resource in an iframe outside their own domain.

The 'X-Frame-Options' response header cannot be modified on an iframe. It is set by the host domain and determines the allowed origins from which the resource can be loaded in a frame.

To resolve this issue, you need to verify the 'X-Frame-Options' setting on the host domain's response headers. If the host domain has disallowed cross-origin framing, there is no way to override this setting from the iframe itself.

Here is an example of inspecting the response headers in Chrome developer tools:

<img src="https://i.sstatic.net/bjM2C.png" alt="enter image description here">

The 'X-Frame-Options' value, in this case 'SAMEORIGIN', is displayed in the 'Response Headers' section.
