Hello!

How can I know if a window is open or not?

Thank you in advance!

if(windowreference&&!windowreference.closed)

//it is opened
}

I believe the syntax is:

windowName.isOpen

that returns a boolean value, so

if (windowName.isOpen){
do stuff if it is open} theEclipse

The following is from the Netscape Javascript Reference at

http://developer.netscape.com/library/documentation/communicator/jsref/index.htm:

The closed property is a boolean value that specifies whether a window has been closed. When a window closes, the window object that represents it continues to exist, and its closed property is set to true.

Use closed to determine whether a window that you opened, and to which you still hold a reference (from the return value of window.open), is still open. Once a window is closed, you should not attempt to manipulate it.
