问题
I want to create a link on page A that links to page B and also clicks on a link on page B once page B has finished loading. Is this possible or would I have to code javascript on that specific page where the link is supposed to be clicked on.

If you simply want to redirect to another page you can check the document.referrer on your site to see where the person came from (url) and then redirect with location.replace("http://example.com/myformpage.htm")

You're right, JS is pretty much run in contained environment (i.e., the original page).
