doubt in window.open() method

[maddymadhans]

hi
can some one help me to find that if a window is already open or not using javascript.

if i am opening a window by clicking a link in home page using window.open() method and if the user again clicks the same link it should check wheather the window is already open and if so that window should be focussed else a new window should be opened. plz help me its urgent.

Thank you
Madhan
