You can use your bookmarks toolbar folder on your browser to quickly validate web pages using the W3C validator. Just drag the buttons below onto your toolbar, and hit either one when you want to validate a page.

Another use for the JavaScript is to put the links on a web page, implementing them to make sure that you don’t get any no referrer header found errors. You can always make the JavaScript an onclick reference with a return false, and have the link point at “http://validator.w3.org/check?uri=referer” for the small number of people without JavaScript enabled.
