What I want to do -
1) On Click of a button I will open a new window(popup).
2) When I click on same button, If the window(popup)is already open I will not open it again instead bring the previously opened window(popup) on top of all windows.
3) If popup is not open I will use window.open() to open a popup.
What I did till now -
1) On Click of a button I will open a new window(popup).
2) Problem : How do I not allow opening of new window on click of button if window is already open?
