making link disappear from window.open pop up
<p>I have link that opens a window, with <code>window.open("mytest.aspx");</code> the problem i am having is that when they close that pop up window I need to hide that link on the parent page. So basically, how can I hide the link (which is an anchor) on the parent page from the pop up that was opened with window.open() ?</p>

<p>Thank you</p>
