//<pre>//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:<your username>/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 [[Wikipedia: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 . Thanks to Superm401 and drrngravy for their//improvements.////(Every line that starts with "//" is a comment and can be discarded.)functionexternISBN(){varmagicURL="http://www.amazon.com/s?search-alias=stripbooks&field-isbn=MAGICNUMBER";varmagicRegex=/MAGICNUMBER/ig;if(mw.config.get('wgPageName')!="Special:Booksources"&&mw.config.get('wgPageName')!="Wikipedia:Book_sources"){for(vari=0;i<document.links.length;i++){if(document.links[i].href.match(/Special:BookSources\/(.*)/)){document.links[i].href=magicURL.replace(magicRegex,RegExp.$1);}}}addOnloadHook(externISBN);//</pre>
