javascript - opening a different webpage from my webpage and reading its content /clicking buttons etc -

I was just curious how to do it.

I want to open www.whatsmyip.com

Click on the button

Read more values ​​(a text box that looks like).

I want to achieve all this program without any human contact.

How is this possible?

The example you posted is possible not .

You can not read the contents of the frame from any other domain (though it is possible on a subdomain or on the same domain), this is a restriction for security reasons.

What if I can launch gmail.com and my login name, what about your online banking site? :) You can see how quickly it will be misused if permission is given.
