Can you access properties/methods of parent window from the child?

Question

if I create a popup in JavaScript I can access its properties:

var myWin = window.open("test.htm");
myWin.property1;

but my question is, can I access properties/methods of parent window from the child?

Answer 1

Yes. Just do window.opener, this will get you access to the parent window. For example, to refresh the parent window, you can do

window.opener.location.refresh();
