Code:
parent.htm

<a href='child_as_newWindow.htm' target='_blank'>
child_as_newWindow
</a>
If a user clicks the link above, a newWindow will pop.

I like to write some code in child_as_newWindow.htm.

The code has a button named "close."

If the user clicks the button "close," child_as newWindow.htm will be close.
At the same time, the parent.htm will go to another_parent.htm.

Can I do it with your help?
