Hi, Would someone please explain how to use the popup\_javascript\_function in urlhelper. I need to have a popup window opened when a user click on a link and I think that action is written for that purpose. Unfortunately I don’t quite understand what to pass to the popup parameter and perhaps more. I have not found documentation or example on this either. Please help! Thanks! ---

Why not use a link\_to with a :popup parameter?
