Check if the child window is open from parent window

[magnon]

Hi,

how can I check if the child window i created is still active or if it is closed?
hopefully that it would work on IE and FF

when you create it you need to assign the window object to a variable


var win = window.open(.....);


now, since you have a reference to the window object, you can check the property closed

if (win.closed)
alert('closed');
else
alert('still open');

hope this does the trick for you ;)
