From: Rich on 26 Feb 2006 01:14 I have the following script on all pop up windows, would like to have this work on all newer browsers if possible. Right now it only works on MSIE & Opera. Not sure why. Any suggestions are appreciated. Not concerned with the print part yet. TIA Rich <SCRIPT language="jscript"> function CloseWindow() { self.close(); } function printpage() { window.print(); } </SCRIPT> <a href="#" onclick="printpage()">Print</a> | <a href="#" onclick="CloseWindow()">Close Window</a>
From: Manifest Interactive on 26 Feb 2006 03:06 Greetings, You really only need to use the code window.close(); window is standard for most DOM's so you should not have any issues with this. HOWEVER due to most security features in standard browsers, this function, no matter how you write it, will only work in a window that was launched using javascript. In other words, if you open a new browser page and access the URL that contains this script and have try to close the window, it will do one of two things: 1. It will prompt an alert telling you that a script is trying to close the window and it will ask if you that is OK. 2. It will ignore you script and do nothing. The above only happen if you are in the PARENT window. If you are launching a new window through javascript then it is assumed you have permission to close the window and you will then be able to close it just fine. I hope this helps, - Peter Schmalfeldt Manifest Interactive

It will close the window in 90% (if not more) of the browsers on the web if you add one more line of code. > The above only happen if you are in the PARENT window.

I can close it, most of the time, even if script didn't open it. At least until IE7 is released anyway. > I hope this helps, It didn't, only confused because of your lack of quoting what you were replying to.

Right now it only works on MSIE & Opera. I've filed a bugreport on the usage of window.close() at Microsoft and Opera when closing a non-javascript-initiated window: Microsoft fixed it in IE7 beta 2 and you can expect Opera to fix it too in Opera 9. There is absolutely no reason as to why a browser should honor a script closing a non-javascript-initiated window without the user's explicit consent. Any window can be closed by the user with Alt+F4; any window with a titlebar can be closed by the user by clicking the close command icon. Mozilla goes a bit further with dom.allow_scripts_to_close_windows in its user settings. > Not sure why. Any suggestions are appreciated. Here's one suggestion. Do not duplicate the normal browser commands, the UI-based ones: because - it's unneeded, - it requires javascript support, - it wrongly induce the users to trust websites more than their browser commands and induce the users into not using their own browsers - it does not induce users to get to know the commands of their own browsers. So: - do not create close buttons or, worse, "close" links - do not create go back buttons or, worse, "go back/history" links - do not create increase/decrease font size buttons or, worse, "increase/decrease font size" links (1) - do not create print buttons or, worse, "print" links; with maybe only 1 exception if the link is to print a frame in a frameset...but even there, I strongly oppose frames-based design to begin with and anyway, the native UI for printing indicate how/which frame(s) can be printed. (1): but you can show the users how to increase the font size. This is what w3schools.com does at their site (see Larger text? link: http://www.w3schools.com/largetext.htm ) and I think this is very good into helping users to get to know their browser commands and get to know + trust their browser. Empowering the users and letting them in control of the technology is a winning strategy. > Not concerned with the print part yet.
