Javascript - Jumping between browser Tabs

Question

My program consists of two browser tabs. I open the second tab from the first tab via window.open(..) . Can I induce changes in the first tab from the second tab? Like sending new Ajax requests etc.

Answer 1

Yes, you can, since window.open() returns a reference to the new window, and from the new window, you can access the parent window through its opener property.

You should see : http://www.w3schools.com/jsref/prop_win_opener.asp

So you could invoke functions that are in the parent from the new window ( opener.functionName() ) and invoke functions of the new window from the parent ( var newWindow : window.open(...); newWindow.functionName2() );
