How to solve a Cross Orgin Issue in IFrame?

Question

Hi,

 

In my web application,  i have Iframe and loaded another domain URL. I need to access the focus and unload methods of Iframe. In past, I have achieved the same by disabling the Chrome security and using Allow X-Frame header extension.

 

But unfortunately, Google chrome was not allowed to disabling the security features in the latest version(last month update).

 

I am getting the below error. 

 

 

 

If anyone solved this issue before please let me know the solution.

 

Thanks in advance.
