This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
In my jsp I am calling window.popup but I don't want to create a popup if the user already has the popup open when using a different browser tab or session.
Instead I would like to prompt the user to close the popup before continuing.
Is there a way of doing this ?
