//This code will change ISBN links to point to the url of your choice, //instead of Special:Book_sources. // //How to use it: // //First, you must copy this code to your user javascript page. This is //at User: /monobook.js. My username is Lunchboxhero so //my javascript page is User:Lunchboxhero/monobook.js. You must be logged //in to edit your javascript page. // //Once you have copied the code and saved the page, you need to refresh your //browser's cache. For Mozilla/Safari/Konqueror: hold down Shift while clicking //Reload (or press Ctrl-Shift-R), IE: press Ctrl-F5, Opera: press F5. // //The code should now work, as long as you are logged in. // //You can change the destination URL. Go to Book sources and copy the URL of the site you want to use (right-click the link, then click "Copy Link Location", "Copy Target", or similar). Put the new URL between the quotes next to magicURL, in place of the URL now there. // //Good luck, and if you have any questions, leave a comment on the discussion //page of User:Lunchboxhero/monobook.js. // //(Every line that starts with "//" is a comment and can be discarded.)
