Chrome blocks different origin requests

When script tries to access a frame from a different origin Chrome blocks it and throws exception as

"Uncaught SecurityError: Blocked a frame with origin 'provider domain' from accessing a frame with origin 'mydomain'. Protocols, domains, and ports must match".

I got this error after some update in google chrome. Any suggestions?

How do I fix cross origin requests are only supported for protocol schemes Chrome Chrome extension https?

Just change the url to http://localhost instead of localhost . If you open the html file from local, you should create a local server to serve that html file, the simplest way is using Web Server for Chrome . That will fix the issue.

Direct Javascript calls between frames and/or windows are only allowed if they conform to the same-origin policy. If your window and iframe share a common parent domain you can set document.domain to "domain lower") one or both such that they can communicate. Otherwise you'll need to look into something like the postMessage() API.
