// This script will close child windows when the parent // window is closed. // // Date: 12/14/1999 // Author: David Wickersham (skeezicks@cyberdude.com) // Version: 1.0 // // Installation Instructions: // 1. Copy this script into a file named popup_closer.js. // 2. Use the script tag to incorporate popup_closer.js // into the head area of the html page: // . // 3. Add the onUnload event handler to the tag: // . // 4. Each time you open a new window using the window.open // method put the new window object into poparray: // poparray[popsub] = window.open("[your_popup.html]","[any_name]","[your_window_options]"); // and then increment popsub by 1: popsub++;. // // How It Works: // All popup window objects created during the life cycle // of the parent page are stored in poparray. When the page // is unloaded the script spins through poparray looking // for child window objects that still exist. Any that are // found are closed. // // Compatibility: // Should run on all IE & Netscape browsers but will not // close the child windows for IE browsers prior to version // 4. Tested on IE 5 and Netscape 4. poparray = new Array(); var popsub = 0; function popupCloser() { if (navigator.appName != "Microsoft Internet Explorer" || parseInt(navigator.appVersion) >= 4) { for(popsub = 0; popsub < poparray.length; popsub++) { if(poparray[popsub] != null) { if(!poparray[popsub].closed) { poparray[popsub].close(); } } } } return true; }
