I have some html pages with the same footer. With javascript and only javascript could i import another html page inside it?
You could do a server side include, depending on your webserver. but the quickest way would probably be to create a JavaScript file that uses document.write or similar to output the html syntax. and then just include the created JavaScipt file the normal way. more info at: http://webdesign.about.com/od/ssi/a/aa052002a.htm
