Check if the child window is open from parent window

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(.....);

Code (markup):

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');

Code (markup):

hope this does the trick for you
