    remember all windows I opened

    Hi everybody,

    how can I remember all windows I opened to close them with one click on a
    button? (btw: do arrays exist in Javascript?)

      Keep the references returned by window.open(). Yes, arrays exist. You
      want to use an array for this, do you?

          var myArray = new Array();

          myArray[0] = window;
          myArray[1] = window.self;
          myArray[2] = window.opener;
          //etc

          Of course, replace these windows with the windows you care about.

              Ok. Thats exactly what I am doing now. BUT if I reload my main window, the
              array is reinstantiated and all prior values are gone :-(

                  Yes, that is what happens when you reload the main window. Web pages
                  are stateless, meaning they do not retain data on reloads. There is a
                  mechanisim which can fix that... they are called cookies.

                  If you want a reloaded page to have data from the previous page, you
                  need to either use a cookie, or encode it in the search field of the
                  URL, which is really messy. (something like yourpage.html?< your data here>

                  I suppose you could also have a master window or frame, which retains
                  the data you need... But that is messy too.

                  Come to think of it, having multpile windows open at the same time is
                  messy to begin with :)

                      Wenn du eine Array verwendet, warum noch danach fragen?

                      But that aside. <body onunload="clean up()"> and then close all child
                      windows from the cleanup function.

                      Too harsh? Some other approach that comes to mind is some 'anchor
                      construct', where children windows keep an eye on the parent and start a
                      relinking procedure when the content refreshes.

                      Does the array die as well if it sits in an external script?
